Answer:

Area ≈ 1256 [tex]in^{2}[/tex]

Step-by-step explanation:

The formula to find the area of a circle is [tex]\pi r^{2}[/tex]

the diameter of this circle is 40 inches. The radius is half of that, 20 inches.

[tex]\pi 20^{2}[/tex] = [tex]400 \pi[/tex]

[tex]400\pi[/tex] ≈ 1256

Area ≈ 1256 [tex]in^{2}[/tex]

Pat’s Pizza Place sells large pies for $12 with a charge of $2 for each topping.

Answers

Answer:

A number line going from 2 to 7. A solid circle is at 4. Everything to the left of the circle is shaded.

Step-by-step explanation:

The pizza itself will cost $12, and because toppings cost $2 apiece, the maximum amount of toppings that can be used is 4.

4·2=8

8+12=20

So, by putting a closed circle on 4, going to the left, the line shows that she can buy anywhere from 0-4 topping on her pizza.

How many committees can be formed by choosing 4 men from an organization of a membership of 15 men?


Answers

The selection of the committee members is an illustration of combination

There are 150150 different ways of selecting the committee

How to determine the total selection

The number of members (n) is:

n = 15

The members on the committee are (r):

r = 4

So, the number of selection is:

[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]

This gives

[tex]^{15}C_4 = \frac{15!}{(15 - 4)!4!}[/tex]

Evaluate the differences

[tex]^{15}C_4 = \frac{15!}{9!4!}[/tex]

Expand

[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10 * 9!}{9!4!}[/tex]

This gives

[tex]^{15}C_4 = \frac{15* 14 * 13 * 12 * 11 * 10}{4!}[/tex]

[tex]^{15}C_4 = 150150[/tex]

Hence, there are 150150 different ways of selecting the committee

Triangle P Q R is shown. Angle P Q R is a right angle. The length of Q R is p, the length of R P is q, and the length of P Q is r. Which sine ratios are correct for ΔPQR? Check all that apply.
A. sin (P) = StartFraction r Over q EndFraction
B. sin (P) = StartFraction p Over q EndFraction
C. sin (Q) = StartFraction r Over p EndFraction
D. sin (R) = StartFraction q Over r EndFraction
E. sin (R) = StartFraction r Over q EndFraction

Answers

Step-by-step explanation:

answer is in the picture

Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.

To determine the correct sine ratios for ΔPQR, let's recall the definitions of sine for each angle in a right-angled triangle.

In a right-angled triangle ΔPQR:

1. sin(P) = opposite side / hypotenuse = r / q (Correct) [By definition of sine in a right triangle, sin(P) = opposite/hypotenuse]

2. sin(Q) = opposite side / hypotenuse = r / p (Correct) [By definition of sine in a right triangle, sin(Q) = opposite/hypotenuse]

3. sin(R) = opposite side / hypotenuse = q / r (Correct) [By definition of sine in a right triangle, sin(R) = opposite/hypotenuse]

Option A (sin(P) = r/q), Option C (sin(Q) = r/p), and Option D (sin(R) = q/r) are correct sine ratios for ΔPQR. Option B (sin(P) = p/q) and Option E (sin(R) = r/q) are not correct sine ratios for ΔPQR.

Find the value of y in the solution to the system of equations shown. y=5x+3 2y=18x-10

Answers

Answer:

13

Step-by-step explanation:

To find the value of y, we will use the substitution method

Plug the y of the top equation into the other equation

2(5x + 3) = 18x - 10

Distribute the 2 into the equation inside the parenthesis

10x + 6 = 18x - 10

Subtract 10x from both sides

10x + 6 = 18x - 10

-10x        -10x

6 = 8x - 10

Add 10 to both sides

6 = 8x - 10

+10      + 10

16 = 8x

Divide both sides by 8

16/8 = 8x/8

x = 2

Sub the 2 in the place of x into one of the original equations. We will use the first one.

y = 5(2) + 3

y= 10 + 3

y = 13

Answer:

y = 13

Step-by-step explanation:

y = 5x + 3

2y = 18x- 10

substitution (substituting y with the y value given):

2( 5x + 3 ) = 18x - 10

solve:

10x + 6 = 18x - 10

10x - 18x = -10 - 6

-8x = -16

x = 2

now plug in the x:

y = 5( 2) + 3

y = 10 + 3

y = 13

Answers

A square prism has the same the base area and volume as the square pyramid is 4 units.

What is the volume of square pyramid?

The volume of a square pyramid is,

[tex]a^{2} *h/3[/tex]

[tex]256=a^{2} *12/3[/tex]

[tex]256=4 a^{2}[/tex]

[tex]256/4=a^{2}[/tex]

[tex]64=a^{2}[/tex]

[tex]a=8[/tex]

Now we know that the square is 8 by 8.

A square pyramid has a height of 12 units and a volume of [tex]256 units^3[/tex]

What is the volume of of a square prism?

The volume of a square prism is a²h

[tex]V=a^{2} h[/tex]

[tex]256=64h[/tex]

[tex]256/64=h[/tex]

[tex]h=4[/tex]

The height is 4 unit

Also, a square pyramid is 1/3 the volume of a square prism.
