Final answer:
The digit in the hundredths place of the number 9.014 is 1. Significant figures and rounding concepts determine that if the digit in the thousandths place is 5 or greater, the hundredths place digit is rounded up.
Explanation:
The digit in the hundredths place of the number 9.014 is 1. When dealing with decimal numbers, the first place to the right of the decimal point is the tenths place, the second place is the hundredths place, and so on. In the context of significant figures and rounding, if we need to round a number to the hundredths position, and the digit in the thousandths place (the third position to the right of the decimal) is 5 or greater, we round the hundredths digit up.
For example, if the calculator answer is 921.996 and we need to round to the hundredths place, we look at the thousandths place digit. Since it is greater than 5, we round up, changing the answer to 922.00.

2. Sue is buying a 13-pound mixture of gummy candy, jelly beans, and hard candy. The cost of gummy candy is $1.20 per pound, jelly beans cost $2.00 per pound, and hard candy costs $2.60 per pound. The mixture calls for three times as many gummy candy pieces as jelly beans. The total cost of the mixture is $21.80. How much of each ingredient did the store use?
Answer:
Store used 7.5 pounds of gummy candy, 2.5 pounds of jelly beans, and 3 pounds of hard candy.
Step-by-step explanation:
Let the amount of gummy candy be 'x'.
Let the amount of jelly beans be 'y'.
Let the amount of hard candy 'z'.
Now Given:
Sue is buying 13 pound of mixture.
So we can say that;
[tex]x+y+z =13[/tex]
But Given:
The mixture calls for three times as many gummy candy pieces as jelly beans.
[tex]x=3y[/tex]
Substituting the value of x in above equation we get;
[tex]3y+y+z=13\\\\4y +z =13 \ \ \ \ \ equation \ 1[/tex]
Also Given:
cost of gummy candy = $1.20
cost of jelly beans = $2.00
cost of hard candy = $2.60
Total Cost of mixture = $21.80
Now Total Cost of mixture is equal to cost of gummy candy multiplied amount of gummy candy plus cost of jelly bean multiplied amount of jelly bean plus cost of hard candy multiplied amount of hard candy.
framing in equation form we get;
[tex]1.2x+2y+2.6z=21.80[/tex]
But [tex]x=3y[/tex]
So [tex]1.2(3y)+2y+2.6z=21.80\\\\3.6y+2y+2.6z=21.80\\\\5.6y+2.6z=21.80[/tex]
Now Multiplying by both side by 10 we get;
[tex]10(5.6y+2.6z)=21.80\times 10\\\\10\times5.6y + 10\times2.6z =218\\\\56y+26z=218 \ \ \ \ \ equation \ 2[/tex]
Now Multiplying equation 1 by 14 we get;
[tex]14(4y +z) =13\times14\\\\14\times4y +14z =182\\\\56y+14z=182[/tex]
Now Subtracting equation 3 from equation 2 we get;
[tex](56y+26z) - (56y+14z) =218-182\\\\56y +26z-56y-14z=36\\\\12z=36\\\\z=\frac{36}{12} = 3 \ pounds[/tex]
Now Substituting value of z in equation 1 we get;
[tex]4y+z=13\\\\4y+3=13\\\\4y=13-3\\\\4y = 10\\\\y=\frac{10}{4} = 2.5 \ pounds[/tex]
Now also;
[tex]x= 3y\\\\x =3\times2.5 =7.5 \ pounds[/tex]
Hence Store used 7.5 pounds of gummy candy, 2.5 pounds of jelly beans, and 3 pounds of hard candy.

an airport shuttle company owns cars that have a maximum capacity of 3 passengers and vans that have a maximum capacity of 8 passengers . their 12 vehicles have a combination maximum capacity of 61 passengers. write and solve a system of equations to determine how many vans the company owns
Answer:
The Total number of car is 7 and The Total number of van is 5 .
Step-by-step explanation:
Given as :
The maximum capacity of car = 3 passengers
The maximum capacity of van = 8 passengers
Total number of vehicles = c + v = 12 vehicles
The maximum capacity of vehicles combination = 61 passengers
Let The Total number of car = c
Let The Total number of van = v
Now, According to question
c + v = 12 .........A
3 c + 8 v = 61 ............B
Now, Solving eq A and B
I.e (3 c + 8 v) - 3 × (c + v) = 61 - (3 × 12)
Or, (3 c - 3 c) + (8 v - 3 v) = 61 - 36
Or, 0 + 5 v = 25
∴ v = [tex]\dfrac{25}{5}[/tex]
i.e v = 5
So,The Total number of van = v = 5
Now Put the value of v into eq A
∵ c + v = 12
So, c + 5 = 12
∴ c = 12 - 5
i.e c = 7
So,The Total number of car = c = 7
Hence,The Total number of car is 7 and The Total number of van is 5 . Answer
The student's question is about determining the number of vans owned by a company using a system of linear equations. By setting up two equations and using the elimination method, we find that the company owns 5 vans and 7 cars.
Explanation:The question involves solving a system of linear equations to determine how many vans a company owns. We know that the company has a total of 12 vehicles, which are either cars with a capacity of 3 passengers or vans with a capacity of 8 passengers. The total capacity of all 12 vehicles combined is 61 passengers. To solve this problem, we will create two equations based on this information:
Let c represent the number of cars and v represent the number of vans.The first equation is based on the number of vehicles: c + v = 12.The second equation represents the total capacity: 3c + 8v = 61.We can solve this system using substitution or elimination methods.Using elimination to solve the equations:
Multiply the first equation by -3 to align the passenger capacity of the cars: -3c - 3v = -36.Add this result to the second equation: (-3c - 3v) + (3c + 8v) = -36 + 61.Simplify the equation: 5v = 25.Divide both sides by 5 to find v: v = 5.Substitute v back into the first equation: c + 5 = 12.Solve for c: c = 7.Therefore, the company owns 7 cars and 5 vans.

Answer:
x = 7, y = 28
Step-by-step explanation:
We're given that ABCD is a rectangle, so we know that all sides opposite from each others are equal in length. This also means that each part of the criss-cross-X thing inside the rectangle are equal in length to each others as well. (AE = BE = DE = CE).
AC = 100 from the given picture, which means half of that from AE would be 50. Since DE is the same length as AE, we can set x²+1 = 50 and solve for x. We get x = 7.
To solve for y, we know that opposite sides of a rectangle are of the same length. So AD = BC.
The question already gave us the equation for those sides so we just need to set them equal to each other.
2y + 5 = 3y - 23
sovle for it and you get y = 28.

If the range of f (x) = StartRoot m x EndRoot and the range of g (x) = m StartRoot x EndRoot are the same, which statement is true about the value of m? m can only equal 1. m can be any positive real number. m can be any negative real number. m can be any real number.
Answer:
b. m can be any positive real number.
Step-by-step explanation:
The value of m can be any positive real number. The correct answer is option b) m can be any positive real number.
Step 1
To determine the value of m that makes the ranges of [tex]\( f(x) = m^x \)[/tex] and [tex]\( g(x) = x^m \)[/tex] the same, we need to analyze the ranges of both functions.
Analyzing [tex]\( f(x) = m^x \)[/tex] :
- If [tex]\( m > 0 \)[/tex], [tex]\( m^x \)[/tex] is an exponential function.
- For [tex]\( m > 1 \)[/tex], [tex]\( f(x) = m^x \)[/tex] increases and its range is [tex]\( (0, \infty) \)[/tex].
- For [tex]\( 0 < m < 1 \)[/tex], [tex]\( f(x) = m^x \)[/tex] decreases and its range is also [tex]\( (0, \infty) \)[/tex].
Step 2
Analyzing [tex]\( g(x) = x^m \)[/tex] :
- The range of [tex]\( x^m \)[/tex] depends on whether m is positive or negative:
- For positive m :
- When [tex]\( m = 1 \)[/tex], [tex]\( g(x) = x \)[/tex], the range is all real numbers, [tex]\( \mathbb{R} \)[/tex].
- When [tex]\( m > 1 \)[/tex] or [tex]\( 0 < m < 1 \)[/tex], the function is defined for [tex]\( x > 0 \)[/tex] and its range is [tex]\( (0, \infty) \)[/tex] .
- For negative m :
- The function [tex]\( x^m \)[/tex] is undefined for [tex]\( x = 0 \)[/tex] and for negative x, and thus its range is [tex]\( (0, \infty) \)[/tex].
Both [tex]\( f(x) = m^x \)[/tex] and [tex]\( g(x) = x^m \)[/tex] have the range [tex]\( (0, \infty) \)[/tex] for any positive [tex]\( m \)[/tex], but for any negative m, [tex]\( g(x) \)[/tex] is undefined at zero and for negative x.
The value of m can be any positive real number (option b).
Complete question : If the range of f(x) = ^mx and the range of g(x) = m ^ x are the same, which statement is true about the value of m?
a) m can only equal 1.
b) m can be any positive real number.
c) m can be any negative real number.
d) m can be any real number.

y= 2 / 3x + 7 / 3
Omar has 2 3/4 cups of dough to make dumplings. If he uses 3/16 cups of dough for each dumpling, how many whole dumplings can Omar make?
Plsss help me
Answer: Omar can make 14 whole dumplings.
Step-by-step explanation: Make 2 3/4 an improper fraction. To do this, multiply 2 by the denominator, 4. From this, you get 8. Then add 8 to the numerator, which is 3, and you get 11. Keep the denominator and you'll have 11/4.
To divide fractions, you make 3/16 its reciprocal by basically flipping the fraction so that the numerator becomes the denominator and vise versa, making it 16/3. Then multiply 11/4 and 16/3. 11 x 16 is 176; 4 x 3 is 12. The result is 176/12. Simplify by dividing the numerator and denominator by 4. Your resulting answer should be 44/3. Simplify even further by simple division. Your final answer should be 14 2/3. Discard the 2/3 because Omar needs to make whole dumplings. So the answer is 14.
Final answer:
Omar can make 14 whole dumplings with 2 3/4 cups of dough when each dumpling requires 3/16 cups of dough.
Explanation:
The student's question asks how many whole dumplings Omar can make with 2 3/4 cups of dough if each dumpling uses 3/16 cups of dough.
Convert 2 3/4 cups to an improper fraction: 11/4 cups.
Divide the total cups of dough (11/4) by the amount needed for one dumpling (3/16) to find the number of dumplings Omar can make.
Perform the division: (11/4) \/ (3/16) = 11/4 \\* 16/3 = 44/3.
Omar can make 44/3 dumplings, which is 14 whole dumplings with some dough left over.
Omar can make 14 whole dumplings with 2 3/4 cups of dough when each dumpling uses 3/16 cups of dough.

To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz. However, when Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz. What is the percent error?
(Explain in a detailed way on how you got your answer)
The percent error is 4.17 %
Solution:
To be labeled as a jumbo egg, the egg is supposed to weight 2.5 oz
When Desmond buys a carton of jumbo eggs, the weight of one is 2.4 oz
To find: percent error
Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%
[tex]\% \text { error }=\frac{\text {approximate value}-\text {exact value}}{\text {exact value}} \times 100[/tex]
Here approximate value = 2.5 oz and exact value = 2.4 oz
[tex]\% \text { error }=\frac{2.5-2.4}{2.4} \times 100\\\\\% \text { error }= \frac{0.1}{2.4} \times 100 = 4.17[/tex]
Therefore percent error is 4.17 %

Which angle is an acute angle?
(Full question above)
Answer:
∠CPB is an acute angle.
Step-by-step explanation:
Firstly, lets go over what an acute angle is. An acute angle is any angle that is less than 90°.
In the problem, we are told that ∠APE is a right angle. This means that it is 90°.
As ∠APE and ∠BPD are vertical angles, they must have the same measure. This means that ∠BPD is also 90°
As ∠BPD has the line PC in the middle of it, this angle could be split into ∠CPB and ∠CPD. These two angles must add up to be the same as ∠BPD, which is 90°. As these two angles must add to be 90° they must be less than 90°. This means that both ∠CPB and ∠CPD are acute angles.
As ∠CPD is not one of the options for the question, ∠CPB is the only correct answer.
Acute angles measure less than 90°. Among the options, only C) Angle CPB fulfills this condition. It's the only angle clearly smaller than a right angle in the image.
An acute angle is an angle that measures less than 90 degrees. In the image you sent, only one of the angles measures less than 90 degrees.
-angle APE is a right angle, which measures exactly 90 degrees.
-angle CPE and angle APC are both obtuse angles, which measure more than 90 degrees but less than 180 degrees.
-angle CPB is the only angle that measures less than 90 degrees, so it is the only acute angle.
Therefore, the answer is C) Angle CPB.

Each section represents an angle (capital) and its opposite side (lowercase). When you use it, only use two sections at a time. You may have one missing piece of information when using it. Use the formula that puts the missing information in the numerator (top).
This problem:
We are given one set of information, 8cm and 55°. This can be "a" and "A" (not labelled).
We need angle B to find side b.
Since we are given two of the three angles in the triangle, and the sum of all interior angles of any triangle is 180°, we can find the missing angle.
∠B = 180° - (∠A + ∠C)
∠B = 180° - (55° + 82°)
∠B = 43°
Use the law of sines with sections "A" and "B", with the lowercase letters in the top.
[tex]\frac{a}{sinA} =\frac{b}{sinB}[/tex] Substitute known measurements
[tex]\frac{8cm}{sin(55)} =\frac{b}{sin(43)}[/tex] Rearrange to isolate "b"
[tex]b = \frac{8cm}{sin(55)}X{sin(43)}[/tex] Solve, degree mode on calculator
[tex]b = 6.660...cm[/tex] Exact answer
[tex]b = 6.7cm[/tex] Rounded to nearest tenth
Therefore side b is 6.7cm.

Find the solution(s) for x in the equation below. x^2 + 10x + 21= 0
The solutions for ‘x’ in the given equation are – 3 and - 7
Step-by-step explanation:
Given equation:
[tex]x^{2} + 10 x + 21 = 0[/tex]
To find the ‘x’ value, try to factor, because in this case it works, it's fast. By using factor method, we get
(x + 3) (x + 7) = 0 (adding both value we get 10 and multiply as 21 as in equation and check with signs also while factoring)
x = - 3, -7
Verify above values by multiply both terms,
(x + 3) (x + 7) = 0
[tex]x^{2} + 7 x + 3 x + 21 = 0[/tex]
[tex]x^{2} + 10 x + 21 = 0[/tex] (so values obtained from factor method are correct)
Or, can use quadratic formula, for [tex]a x^{2} + b x + c=0[/tex], the solutions are given by:
[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]
In the given equation, a = 1, b = 10, c = 21, apply these in above formula
[tex]x=\frac{-10 \pm \sqrt{10^{2}-(4 \times 1 \times 21)}}{2(1)}=\frac{-10 \pm \sqrt{100-84}}{2}[/tex]
[tex]x=\frac{-10 \pm \sqrt{16}}{2}=\frac{-10 \pm 4}{2}[/tex]
So,
When [tex]x=\frac{-10+4}{2}=\frac{-6}{2}=-3[/tex]
When [tex]x=\frac{-10-4}{2}=\frac{-14}{2}=-7[/tex]
Hence, the values for ‘x’ are - 3 and - 7

Answer:
[tex]x^2=3x(x-2)[/tex]
Step-by-step explanation:
Let length of square be "x"
According to problem,
Length of Rectangle is 3 times, so
Length of Rectangle = 3x
Also,
Width of rectangle is 2 units less than length of square, so
Width of Rectangle = x - 2
Now, area of square is Side * Side
and
area of rectangle = length * width
Hence,
Area of Square = [tex]x^2[/tex]
Area of Rectangle = [tex](3x)(x-2)[/tex]
If they are equal, we can write:
[tex]x^2=3x(x-2)[/tex]

m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)
Step-by-step explanation:
In the diagram. check attach image
m∠A + m∠B + m∠C + m∠D = 360º.
Every quadrilateral can be decomposed (cut apart) into two triangles, each of whose angles' measures sum to 180º.
m∠A + m∠1 + m∠ 3 = 180º
m∠C + m∠2 + m∠4 = 180º
m∠A+m∠1+m∠3+m∠C+m∠2+m∠4 = 360º
therefore :
m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)

Turn both into improper fractions.
6 1/3 = 19/3
4 1/9 = 37/9
Find common denominators
19/3 = 57/9
37/9
Subtract.
57/9 - 37/9 = 20/9
Turn back into a mixed number.
20/9 = 2 2/9
Best of Luck!
Answer:
2 2/9

8 over 15 minus 1 over 5
Answer:
1/3
Step-by-step explanation:
(8/15) - (1/5)
change 1/5 to 3/15 (which is equivalent to 1/5)
(8/15) - (3/15) = (5/15)
Simplify
(5/15) = (1/3)
Answer:
1/3
Step-by-step explanation:
8/15-1/5=8/15-3/15=5/15=1/3
e. A semicircular window with a radius of
36 inches allows light through an area of how
many square feet? You may use a calculator
if one is available. Round your answer to the
nearest square foot.
Answer:
14 sq. ft [tex](14 ft^{2})[/tex]
Step-by-step explanation:
First, we know that the area of a circle is [tex]\\ A_{circle} =\pi * r^{2}[/tex], where r is the radius of the circle, and [tex]\pi[/tex] is the ratio of the length of a circle's circumference to its diameter, that is, [tex]\pi[/tex]=3.1415926535 ... . But we have here a semicircle.
So, the area of a semicircle is [tex]\\ A_{semicircle} = \frac{1}{2} (\pi * r^{2})[/tex].
We also know that 1 feet = 12 inches, so 36 inches are:
[tex]\\ \frac{1ft}{12inches} * 36 inches = 3 ft[/tex]
Then, the area of the semicircular window is:
[tex]\\ A_{semicircular-window} = \frac{1}{2} (\pi * 3^{2})[/tex] ≈ 14.1372.
Well, rounding the answer to the nearest square foot, we have that the semicircular window allows light through an area of 14 sq. ft [tex] (14 ft^{2})[/tex].
