Answer:
The amount paid to an employee was 162Step-by-step explanation:
The expression 12h + 30w Identifies the amount paid to an employee.Let h represent hours and let w represent the total amount of g-wagons sold. Since the question explains that an employee works 6 hours and sells 3 wagons, put h as h = 6 and w as w = 3. We would end up getting this equation. 12h + 30w = 12(6) + 30(3).Now all you need to do is solve it.left side = 72right side = 9072 + 90 = 162For which of the following is the arc between the two hands of a clock greater than a semicircle?
The long arm is at 12 and the short arm is in-between the 12 and the 1
A The hands are at 11 and 6; arc measured clockwise
B The hands are at 11 and 6; arc measured counterclockwise
C The hands are at 2 and 8; arc measured counterclockwise
D The hands are at 2 and 8; arc measured clockwise
Answer:
A
Step-by-step explanation:
Each hour is 30 degrees. 11 to 6 is 7 hours so 30 * 7 = 210 degrees, which is greater than a semicircle, which is 180 degrees.
Answer:
A. The hands are at 11 and 6; arc measured clockwise
Step-by-step explanation:
A semicircle measures 180º and when you measure the distance from 11 to 6 the difference in the hands of the clock by each hour is given by the equation:
[tex]\frac{360}{12}[/tex]= 30
So there are 7 numbers between the 11 and the 6 if you measure it clockwise, that means that the angle formed by the two hands of the clock measured clockwise is:
7*30= 210
Wich is greater than 180º, which is why that is the correct answer.

Answer:
A (and C)
Step-by-step explanation:
A relationship that is a direct proportion is described by the equation ...
y = kx
for some constant k.
You can examine the tables to see what the value of k is by looking at ...
k = y/x
__
In table A, the values of k are 125/5 = 250/10 = 500/20 = 25.
In table B, the values of k are 100/50 = 2, 250/20 = 125, 50/10 = 5. These are not constant, so the relation is not a proportional one.
In table C, the values of k are -125/5 = -250/10 = -500/20 = -25.
In table D, the values of k are 8/2 = 4, 10/4 = 2.5, 12/6 = 2. These values are not constant, so the relation is not a proportional one.
__
We see that the tables of A and C both represent proportional relationships. We usually expect the value of k to be positive, but there is nothing in the definition of a proportional relationship that demands that be the case.
If this is a single-answer question, choose A.
If this is an "all that apply" question, choose A and C.

What is the volume of the square pyramid with base edges 4m and height 3m?
The volume of a square pyramid is a^2 * h/3, assuming a is the base edge and h is the height. Plug the numbers in and you get your answer.
The volume of the square pyramid with base edges of 4 m and height 3 m is [tex]16 \, \text{m}^3[/tex]
To find the volume of a square pyramid, you can use the formula:
[tex]\[ \text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]
For a square pyramid, the base area is the area of the square base. The formula for the area of a square is \( \text{Area} = \text{side}^2 \).[tex]\[ \text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]
Given:
- Base edges = 4 m
- Height = 3 m
1. Calculate the Base Area:
The base of the square pyramid is a square, so its area is:
Base Area = [tex]\text{side}^2[/tex]
Base Area = [tex]4^2[/tex]
Base Area = [tex]16 \, \text{m}^2[/tex]
2. Plug the Values into the Volume Formula:
Now, we can plug the values into the volume formula:
Volume = [tex]\frac{1}{3} \times \text{Base Area} \times \text{Height}[/tex]
Volume = [tex]\frac{1}{3} \times 16 \, \text{m}^2 \times 3 \, \text{m}[/tex]
Volume = [tex]\frac{1}{3} \times 48 \, \text{m}^3[/tex]
Volume = [tex]16 \, \text{m}^3[/tex]
So, the volume of the square pyramid with base edges 4 m and height 3 m is [tex]16 \, \text{m}^3[/tex]

On a map, the North Carolina cities of Raleigh, Durham, and Chapel Hill form a triangle, as shown below. What are the approximate values of the missing measures on the map?
The approximate values are:
c = 55.2°
r = 22.8°
x = 9.9 miles
Explanation- To find angle [tex]c[/tex], we are using the rule of sines: [tex]\frac{a}{sin(A)} =\frac{b}{sin(B)} =\frac{c}{sin(C)}[/tex]
For our triangle [tex]a=21,A=c,b=x,B=r,c=25[/tex] and [tex]C=102[/tex]
Replacing the values we get: [tex]\frac{21}{sin(c)} =\frac{x}{sin(r)} =\frac{25}{sin(102)}[/tex]
We can pick up two suited values to find [tex]c[/tex]:
[tex]\frac{21}{sin(c)} =\frac{25}{sin(102)}[/tex]
[tex]21=\frac{25sin(c)}{sin(102)}[/tex]
[tex]21sin(102)=25sin(c)[/tex]
[tex]sin(c)=\frac{21sin(102)}{25}[/tex]
[tex]c=sin^{-1}(\frac{21sin(102)}{25})[/tex]
[tex]c=55.2[/tex]
- Now that we have angle [tex]c[/tex], we can use the angle sum theorem to find angle [tex]r[/tex].
The angle sum theorem states the the interior angles of a triangle add up to 180°, so:
[tex]r+c+102=180[/tex]
[tex]r+55.2+102=180[/tex]
[tex]r+157.2=180[/tex]
[tex]r=22.8[/tex]
- Now that we have angle [tex]r[/tex], we can use the rule of sines, one more time, to find side [tex]x[/tex]
[tex]\frac{21}{sin(c)} =\frac{x}{sin(r)} =\frac{25}{sin(102)}[/tex]
[tex]\frac{x}{sin(r)} =\frac{25}{sin(102)}[/tex]
[tex]\frac{x}{sin(22.8)} =\frac{25}{sin(102)}[/tex]
[tex]x=\frac{25sin(22.8)}{sin(102)}[/tex]
[tex]x=9.9[/tex]

The first step in determining the solution to the system of equations, y = –x^2 – 4x – 3 and y = 2x + 5, algebraically is to set the two equations equal as –x^2 – 4x – 3 = 2x + 5. What is the next step?
Answer:
The next step is to put all terms into the left side of the equation and group the like trems
Step-by-step explanation:
The first step in determining the solution to the system of equations, [tex]y =-x^2-4x-3[/tex] and [tex]y = 2x + 5[/tex], algebraically is to set the two equations equal as [tex]-x^2-4x-3 = 2x + 5.[/tex]
The next step is to put all terms into the left side of the equation and group the like trems:
[tex]-x^2-4x-3-2x-5=0,\\ \\-x^2+(-4x-2x)+(-3-5)=0,\\ \\-x^2-6x-8=0.[/tex]
Now you can multiply this equation by -1:
[tex]x^2+6x+8=0[/tex]
and solve it using quadratic formula:
[tex]x_{1,2}=\dfrac{-6\pm \sqrt{6^2-4\cdot 8\cdot 1}}{2\cdot 1}=\dfrac{-6\pm\sqrt{4}}{2}=\dfrac{-6\pm 2}{2}=-4,\ -2.[/tex]
At a local basketball game, all tickets are the same price and all souvenirs are the same price. Mr. Smith bought 2 tickets for this basketball game and 1 souvenir for a total of $17.25. Ms. Lockhart bought 5 tickets to the same game and 2 souvenirs for a total of $42.00. How much was a ticket to this game?
*please explain!*
Answer:
The answer is $7.50.
Step-by-step explanation:
First you have to find the price of the souvenirs which were $2.25, just by doing each common price. Then you just do the answer you got divided by two.
The one ticket for this basketball game is $ 7.50, and one ticket for a souvenir is $2.25.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
Let's suppose the price of the one ticket = $x
And the price of the one souvenir = $y
We have:
2x + y = 17.25 ....(1)
5x + 2y = 42.00 ....(2) (from the quetion)
From the equation (1):
y = 17.25 - 2x
Put the value of y in the equation (2), we get:
5x +2(17.25 -2x) = 42
5x + 34.5 - 4x = 42
x = 42 - 34.5
x = $ 7.50
and y = 17.25 - 2x ⇒ 17.25 - 2(7.5) ⇒ $2.25
Thus, the one ticket for this basketball game is $ 7.50, and one ticket for a souvenir is $2.25.

To integrate sec³(x), use integration by parts and trigonometric identities, ultimately resulting in the integral: 1/2 * (sec(x) * tan(x) + ln|sec(x) + tan(x)|) + C.
To integrate sec³(x), we can use integration by parts. Let’s denote the integral by I:
I = ∫ sec³(x) dx
First, we use the identity:
sec³(x) = sec(x) * sec²(x)We know that sec²(x) = 1 + tan²(x), so:
sec³(x) = sec(x) * (1 + tan²(x)) = sec(x) + sec(x) * tan²(x)Now, we use integration by parts:
Let u = sec(x) and dv = sec(x) * tan²(x) dx.Then, du = sec(x) * tan(x) dx and v = tan(x).
Using integration by parts formula ∫ u dv = uv - ∫ v du, we get:
I = ∫ sec(x) * sec²(x) dx = sec(x) * tan(x) - ∫ tan(x) * sec(x) * tan(x) dxWhich simplifies to:
I = sec(x) * tan(x) - ∫ sec(x) * tan²(x) dxWe already know sec²(x) = 1 + tan²(x), so:
tan²(x) = sec²(x) - 1∫ sec(x) * tan2(x) dx = ∫ sec(x)(sec²(x) - 1) dx = ∫ sec³(x) dx - ∫ sec(x) dxI = sec(x) * tan(x) - ∫ sec(x) * tan²(x) dx∫ sec³(x) dx = sec(x) * tan(x) - ∫ sec³(x) dx + ∫ sec(x) dx2∫ sec³(x) dx = sec(x) * tan(x) + ln|sec(x) + tan(x)| + C∫ sec³(x) dx = 1/2 * (sec(x) * tan(x) + ln|sec(x) + tan(x)|) + CWhich pair of angles are corresponding? 10 points <3
Answer: Angles 1 and 5
Step-by-step explanation: Corresponding angles are angles that have the same measures.
Since angle 1 and 5 have the same measure on these lines, that means that the answer must be angle 1 and 5.
A circle has a circumference of 14pi. What is the area in terms of pi?
Step-by-step explanation:
Divide the circumference by pi to get diameter, which is 14. Divide 14 by 2 for the radius, which is 7. Now square the radius to get 49, and multiply by pi for the area.
Area is 49pi.
The area of the circle in terms of π with a circumference of 14π is 49π units².
Given a circle.
Also, given that:
Circumference of the circle = 14π
It is required to find the area of the circle.
It is known that:
Circumference of a circle is:
C = 2πr, where r is the radius.
So, here,
2πr = 14π
2r = 14
r = 7
So, the radius of the circle is 7.
So, the area of the circle is:
A = πr²
= π(7)²
= 49π
Hence, the area is 49π.

What is the total surface area of this rectangular pyramid?
square meters
Answer:
The total surface area = 10956 m²
Step-by-step explanation:
∵ The pyramid is rectangular pyramid
∴ It has a rectangular base with dimensions of 50 m and 78 m
∴ It has four faces each two opposite are congruent
* to find the total surface area, we will find the area of
each face and add them together
- Area base = L × W
∴ Area base = 50 × 78 = 3900 m² ⇒ (1)
- Area of triangular face of dimensions:
base = 50 m and height = 60 m
∵ Area triangle = 1/2 × base × height
∴ Area triangle = 1/2 × 50 × 60 = 1500 m²
∵ We have another triangle congruent to this triangle (opposite faces)
∴ Area of the two congruent faces = 1500 × 2 = 3000 m² ⇒ (2)
- Area of triangular face of dimensions:
base = 78 m and height = 52 m
∵ Area triangle = 1/2 × base × height
∴ Area triangle = 1/2 × 78 × 52 = 2028 m²
∵ We have another triangle congruent to this triangle (opposite faces)
∴ Area of the two congruent faces = 2028 × 2 = 4056 m² ⇒ (3)
∴ Add (1) , (2) and (3)
∴ The total surface area = 3900 + 3000 + 4056 = 10956 m²

in circle O, AD and BE are diameters. the measure of arc AB is 55 and the measure of arc CD is 25 what is the measure of EAC
Answer:
arc EAC = 280 degrees
Step-by-step explanation:
Given: the measure of arc AB is 55 and the measure of arc CD is 25
Vertical angles are equal so <AOB = <DOE = 55
In a circle, the degree measure of an arc is equal to the measure of the central angle.
so if <DOE = 55 then arc DE = 55
As you know, the arc angle to a full angle in a circle = 360
so
arc EAC = 360 - arc CD - arc DE
arc EAC = 360 - 55 - 25
arc EAC = 280
Answer:
arc EAC = 280 degrees
The measure of EAC = 280°

Step-by-step explanation:
The surface area is the area of each face of the cube. The volume is the amount that will fill the cube. These are two separate processes which cannot give you the same measurement by calculating one part of the surface area. B is false.
Doubling the sides of the cube will not double the surface area. It will quadruple it. D is false too.

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Let x be the cost of each water bottle and y be the cost of each nachos.
Two bottled water and an order of cheese nachos costs $5.50.
So, 2x+y=5.50 -------(I)
Three bottled water and two orders of cheese nachos costs $9.50
3x+2y=9.50 -------(II)
Multiply equation (I) by 2, we get
4x+2y=11 -------(III)
Subtract equation (II) from equation (III), we get
4x+2y-(3x+2y)=11-9.50
x=$1.50
Substitute x=1.50 in equation (I), we get
2(1.50)+y=5.50
y=$2.50
Therefore, the cost of each nachos is $2.50.

The area of a square garden is 98 m2. How long is the diagonal?
Answer:
The diagonal is about 14 m
Step-by-step explanation:
A = s^2
98 = s^2
so
s = √98
diagonal c^2 = 98 + 98
c^2 = 196
c = √196
c ≈ 14
Answer:
The diagonal is about 14 m
Answer:
C= 14
Step-by-step explanation:
The side is the square root of the area
S × S = A
S = √98
The diagonal is the hypotenuse of a right triangle formed by the two sides so
a² + b² = c²
Where C = the diagonal A = √98 , B = √98
so C²= (√98)² + (√98)²
This gives: C²= 98 + 98 or
C² = 196
√C² = √196
C= 14
