Answer:
you can make 14 muffins
Step-by-step explanation:
To get this answer you first need to know that 1 cup makes 8 muffins. Next know that there's 1 3/4 cups of flour. Because you know that 1 cup makes 8 muffins you need to figure out how many muffins 3/4 a cup of flour can make. To do this you divide 8 by 4. Hence 8 divided by 4 is 2. So know you know that for every 1/4 cup you can make 2 muffins. Now since there's 3/4 cup of flour you then multiply 2 by 3 which is 6. Now you have to add 1 cup ( 8 muffins) to 3/4 cup ( 6 muffins ) of flour which then equals 14. You then get the answer , 1 3/4 cups of flour can make 14 muffins. Hope this helped ;)

A right cylinder has a radius of 3 and a height of 12. What is its surface area?
A. 457 pi units squared
B. 90 pi units squared
c. 108 pi units squared
D. 72 pi units squared
Answer:
90π units²
Step-by-step explanation:
(refer to attached)
Total Surface are off a right cylinder = area of its ends + area of curved surface
Given radius, r = 3 units and height, h = 12 units
Area of 2 ends,
= Area of 2 circles
= 2 x πr²
= 2π (3²)
= 2π (9)
=18π units²
Area of curved surface,

The circumference of a circle is 8.97cm. Find the length of the diameter. Give your answer rounded to 2 DP. PLEASE HELP ME
Length of diameter is 2.86 cm
Solution:
Given that circumference of a circle is 8.97 cm
To find: length of diameter
We can use the formula for circumference of circle to find radius and then we can find diameter
The circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where "r" is the radius of circle and [tex]\pi[/tex] is a constant equals to 3.14
Substituting c = 8.97 and [tex]\pi = 3.14[/tex]
[tex]8.97 = 2 \times 3.14 \times r\\\\8.97 = 6.28 \times r\\\\r = \frac{8.97}{6.28}\\\\r = 1.4283[/tex]
Thus radius of circle is 1.4283 cm
Finding diameter of circle
diameter = 2(radius)
diameter = 2(1.4283) = 2.8566
On rounding to two decimal point we get, 2.86
Thus length of diameter is 2.86 cm

Step-by-step explanation:
The diagonal of the square creates 2 right triangles with the diagonal as the hypotenuse.
Using Pythagoras' identity in either of the right triangles.
The square on the hypotenuse is equal to the sum of the squares of the other 2 sides.
Let x be the side of the square, then
x² + x² = 40², that is
2x² = 1600 ( divide both sides by 2 )
x² = 800 ( take the square root of both sides )
x = [tex]\sqrt{800}[/tex]
= [tex]\sqrt{100(8)}[/tex]
= = 10[tex]\sqrt{8}[/tex]
= 10 × [tex]\sqrt{4(2)}[/tex]

(02.03) The table below shows two equations: Equation 1 |3x − 1| + 7 = 2 Equation 2 |2x + 1| + 4 = 3 Which statement is true about the solution to the two equations? Equation 1 and equation 2 have no solutions.
Answer:
We can say that equations 1 and 2 have no solutions.
Step-by-step explanation:
The equation 1 is |3x − 1| + 7 = 2 ........ (1)
⇒ |3x − 1| = - 5
This equation is invalid as the absolute value of (3x - 1) will always be positive and here it is - 5.
Therefore, this above equation has no solution.
The equation 2 is |2x + 1| + 4 = 3 ........ (2)
⇒ |2x + 1| = - 1
This equation is invalid as the absolute value of (2x + 1) will always be positive and here it is - 1.
Therefore, this above equation has no solution.
Hence, we can say that equations 1 and 2 have no solutions. (Answer)
Kenny wants to place a picture frame in the center of a wall that is 17 3/4 feet wide. The picture is 2 3/4 feet wide. How many feet from each side of the wall must the frame be so that it is centered?
Answer:
The distance of frame from each side of the wall so that it is at centered is 7.5 feet
Step-by-step explanation:
Given as :
The measure of the wall = 17[tex]\dfrac{3}{4}[/tex] feet
i.e The measure of the wall =[tex]\dfrac{71}{4}[/tex] feet
The measure of the picture = 2[tex]\dfrac{3}{4}[/tex] feet
i.e The measure of the picture =[tex]\dfrac{11}{4}[/tex] feet
Let The distance from each side of wall so that frame at centered = x feet
Now, According to question
x = The measure of the wall - measure of the picture
Or, x = [tex]\dfrac{71}{4}[/tex] feet - [tex]\dfrac{11}{4}[/tex] feet
Or, x = [tex]\dfrac{71 - 11}{4}[/tex] feet
Or, x = [tex]\dfrac{60}{4}[/tex] feet
∴ x = 15 feet
Now, For each side so that frame st centered = [tex]\dfrac{15}{2}[/tex] feet
Or, For each side so that frame st centered = 7.5 feet
Hence,The distance of frame from each side of the wall so that it is at centered is 7.5 feet Answer
find the slope of the line that is horizontal and passes through the point (3,-4). m= ?
Answer: [tex]m=0[/tex]
Step-by-step explanation:
The slope can be calculated with this formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Notice that the formula shows the change in "y" for a unit change in "x" on the line.
In order to solve this exercise, it is important to remember that:
1. If a line is increasing, then its slope is positive.
2. If a line is decreasing, then its slope is negative.
3. If the line is horizontal, its slope is zero.
4. If the line is vertical, it has no slope.
Therefore, since the given line that passes through the point [tex](3,-4)[/tex], is horizontal, its slope is:

List ways to show 46 as tens and ones
Answer:
4 tens 6 ones
Step-by-step explanation:
those are the only way
The number 46 can be expressed as 4 tens and 6 ones, representing the value 40 plus 6, utilizing the powers of ten place value system.
Explanation:When expressing the number 46 in terms of tens and ones, we use the place value system which is based on powers of ten.
In this system, each place in the number represents a power of 10.
To represent 46 as tens and ones, we look for the highest power of ten that fits into the number without exceeding it.
In the case of 46, that value is 40, because 4 tens (4 x 10) equal 40, and there are 6 ones left over.
Therefore, we can say that 46 consists of 4 tens and 6 ones. This can be shown visually as:

Answer:
grapes cost $1.25 per pound
blueberries cost $4 per pound
Step-by-step explanation:
We have two unknowns, the cost of grapes and the cost of blueberries.
I'll call grape g and blueberries b.
since 21lb grapes and 44lb of blueberry cost $202.25, we can set up our first equation.
21g + 44b = 202.25
and the question also said 30lb grape and 22lb blueberries cost $125.50, we can set up our second equation.
30g + 22b = 125.5
now that we have two equations, you can use any methods you want to solve for the variable. I'm gonna use elimination.
21g + 44b = 202.25
-2(30g + 22b = 125.50)
━━━━━━━━━━
-39g = -48.75
g = 48.75/39
g = 1.25, grapes cost $1.25 per pound
now use substitution to find the cost of blueberries. you know the value of g now so plug it back in to one of the equation.
21g + 44b = 202.25
21(1.25) + 44b = 202.25
26.25 + 44b = 202.25
44b = 176
b = 4 , blueberries cost $4 per pound
A car salesman had $65,100 in sales. He earned $1,953 in commission. What percent commission did he earn. Explain your answer.
How long was the loan
Interest earned = $299
Principal = $1300
Interest rate = 7%
Answer:
1. The percent commission earned is 3%.
2. The loan period is 3.29 years.
Step-by-step explanation:
1. Salesman has $65,100 in sales. He earned $1,953 in commission.
Let the percent commission earn be x%
Therefore, x% of the sales equals $1,953
[tex]\frac{x}{100} of $65,100 = $1,953[/tex]
[tex]\frac{x}{100} * 65100 = 1953\\\frac{65100x}{100} = 1953[/tex]
We cross multiply
[tex]\frac{65100x}{100} = 1953\\65100x = 1953 * 100\\65100x = 195300[/tex]
Divide both side by the coefficient of 'x' (65100)
[tex]\frac{65100x}{65100} = \frac{195300}{65100} \\x = 3[/tex]
Therefore, the percent commission earned is 3%
2. Interest (I) = $299 Principal (P) = $1300 Rate (R) = 7%
The formula for finding interest is given as: [tex]I = \frac{PRT}{100}[/tex]
Therefore, substituting into the formula, we have:
[tex]299 = \frac{1300 * 7 * T}{100}[/tex]
We are finding the time it takes the loan to earn an interest of $299
[tex]299 = \frac{1300 * 7 * T}{100} \\299 = \frac{9100T}{100}[/tex]
We cross-multiply:
[tex]299 * 100 = 9100T\\29900 = 9100T[/tex]
Divide both side by the coefficient of T (9100)
[tex]\frac{29900}{9100} = \frac{9100T}{9100}\\T = 3.29[/tex]
Therefore, the time taken for the loan to earn such interest is approximately 3.29 years
Today Robbie is carrying his history textbook and his lunch in his backpack. If the history textbook weighs 2 5/6 pounds and his lunch weighs 1 2/3 pounds, how much weight is in Robbie's backpack?
Final answer:
To find the total weight in Robbie's backpack, the weights of the history textbook (2 5/6 pounds) and lunch (1 2/3 pounds) are added, resulting in a total of 4 1/2 pounds.
Explanation:
The question involves finding the total weight of items in Robbie's backpack: a history textbook and his lunch. The history textbook weighs 2 5/6 pounds and his lunch weighs 1 2/3 pounds.
To find the total weight, we first convert the mixed numbers into improper fractions for easier addition. The history textbook's weight as an improper fraction is (2×6)+5 = 17/6 pounds. The lunch's weight is (1×3)+2 = 5/3 pounds.
Adding these two fractions gives us:
17/6 + 5/3 = 17/6 + 10/6 = 27/6 pounds
Since 27/6 simplifies to 4 1/2 pounds, the total weight in Robbie's backpack is 4 1/2 pounds.

14 ft > [tex]4\frac{1}{2}[/tex] yards
Step-by-step explanation:
Given,
14 ft ____ 4 1/2 yd.
We will convert yards into feet to determine the inequality.
1 yard = 3 feet
[tex]4\frac{1}{2}[/tex] yards = [tex]3*4\frac{1}{2}[/tex]
[tex]4\frac{1}{2}[/tex] yards = [tex]3*\frac{9}{2}[/tex]
[tex]4\frac{1}{2}[/tex] yards = 3*4.5 = 13.5 feet
which is less than 14 feet, making 14 feet greater, therefore, we will use 'greater than' inequality.
14 ft > [tex]4\frac{1}{2}[/tex] yards

How many ounces does a 2-ton rhinoceros weigh?
Answer:
64,000 ounces
Step-by-step explanation:
1 ton = 32,000 ounces
2 tons x 32,000 ounces (which is equal to one ton)
=64,000 ounces
2 tons = 64,000 ounces
A 2-ton rhinoceros weighs 64,000 ounces, which is calculated by converting tons to pounds and then pounds to ounces.
Explanation:The weight of a rhinoceros weighing 2 tons can be calculated in ounces by first converting the weight to pounds. As we know from previous examples, 1 ton = 2,000 pounds. So, a 2-ton rhinoceros weighs 2 × 2,000 = 4,000 pounds. Now, to convert pounds to ounces, we use the conversion factor that 1 pound = 16 ounces. Therefore, a 2-ton rhinoceros weighs 4,000 × 16 = 64,000 ounces.

The width of a rectangle is seven meters less than the length. The perimeter is 58 meters. Find the length and width.
The length of rectangle will be 18 meters and width of rectangle will be 11 meters.
It is given that width of a rectangle is seven meters less than the length.
If perimeter of rectangle is 58 meters then find the value of length and width.
What are the area and perimeter of a rectangle ?
The area of rectangle is A = L × B and the perimeter is 2 ( L + B ) , where ; L = length and B = width.
Let's assume the length of the rectangle is x.
The width of the rectangle will be ;
= x - 7
Also ; the perimeter of triangle is given which is equal to 58 meters.
We know that ; the perimeter of triangle is given by ;
Perimeter = 2 × ( length + width )
So ;
58 = 2 [ x + (x - 7)]
58 = 2 ( 2x - 7 )
58 = 4x - 14
or
4x = 58 + 14
4x = 72
x = 72 ÷ 4
x = 18 meters
So ;
Length = 18 meters
and
Width = 18 -7 = 11 meters
