Answer: 54π

Step-by-step explanation: volume = π · r^2 · h

Step-by-step explanation:

2x+5=3x-12

or, 2x-3x=5-12

or, -x= -7

i.e X=7

again

y+4=3x+2

or, y+4=3*7+2

or, y+4=21+2

or, y+4=23

or, y =23-4

i.e y = 19

hence, the value of X is 7 and y is 19

Answer: 26

2³ + 4(2 + x) for x = 10

- first do 4(2 + x) which is

8+4x

- Evaluate 2 cubed

You get 2 times 2 times 2.

That would get 8

Our expression is 8 + 8+x

x = 10

Substitute the values.

It is Now eight plus 8 plus ten

So when you Calculate eight plus 8 plus 10

You will get 26

Answer:

Step-by-step explanation:

When x = 10, the value of the given expression is:

Correct choice is D

Answer:

(3x-7) (x+1)

Step-by-step explanation:

3x^2 - 4x - 7

First split the middle term

3x^2 + 3x - 7x - 7

Make into two separate expressions

(3x^2 + 3x) (-7x-7)

Take out what you can

3x (x+1) -7 (x+1)

Now you have your answers

(3x-7) (x+1)

Answer:

I think the answer is

[tex]x = \frac{9}{7} [/tex]

Step-by-step explanation:

Reason :

[tex]4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7} [/tex]

Therefore

[tex]x = \frac{9}{7} [/tex]

Answer:

d = 364 feet

Step-by-step explanation:

Given that,

The pressure at depth d is given by :

[tex]P=13+\dfrac{8}{13}d[/tex]

Pressure under water is found to be 237 pounds per square foot

Now, put P = 237 to find d. So,

[tex]237=13+\dfrac{8}{13}d\\\\237-13=13+\dfrac{8}{13}d-13\\\\224=\dfrac{8}{13}d\\\\d=\dfrac{224\times 13}{8}\\\\d=364\ ft[/tex]

So, the depth is equal to 364 feet.

Your answer is 0.19.

I hope this helps you get a good grade on your test!!

Answer:

The manager purchased 28 soccer balls.

Step-by-step explanation:

Since the information states that the athletic department manager purchased a total of 52 balls, you can say that the result of adding up the number of footballs and soccer balls purchased is 52, which can be expressed as:

x+y=52, where:

x is the number of footballs purchased

y is the number of soccer balls purchased

Also, as the statement indicates the price of each type of ball and the total cost, you can say that adding up the results of multiplying the price of each ball for the quantity purchased is equal to the total amount spent, which is:

23.53x+19.86y=1,120.80

Now, you have 2 equations:

x+y=52 (1)

23.53x+19.86y=1,120.80 (2)

To be able to find the value of x and y, first you can isolate x in (1):

x=52-y (3)

Then, you can replace (3) in (2) and solve for y:

23.53(52-y)+19.86y=1,120.80

1,223.56-23.53y+19.86y=1,120.80

1,223.56-1,120.80=23.53y-19.86y

102.76=3.67y

y=102.76/3.67

y=28

Finally, you can replace the value of y in (3) to find the value of x:

x=52-28

y=24

According to this, the answer is that the manager purchased 28 soccer balls.

Answer:

8x^6 esa es la respuesta correcta...

Answer:

Step-by-step explanation:

The "trick" to this problem is knowing that opposite sides of the box add up to 180°

Now that you know that maybe you can solve this?

180= 7x+2 + 6x-4

180 = 13x -2

182 = 13x

14 = x

find y now to find all the angles

180 = 2y + 4 +4y - 4

180 = 6y

30 = y

now solve the x expressions and the y expressions

7x+2

7(14)+2

98 + 2

D= 100°

6x-4

6(14)-4

84-4

B = 80°

2y + 4

2(30) + 4

60 + 4

A = 64°

4y-4

4(30)-4

120-4

C = 116°

Answer:

I think your right but I'm not sure yet

Answer:

SCI or ICS

Step-by-step explanation:

The largest line will have the largest angle opposite to it, so angle SCI is the correct choice.

A = 50.24

To find the area of a circle we can use the following equation

[tex]A = r^2\pi \\A = 4^2\pi \\A = 16\pi \\\\A = 16*3.14\\A = 16*3.14\\\\A = 50.24[/tex]

Answer:

105 eggs

Step-by-step explanation:

Total eggs they bought = ( 8×12) = 96 eggs

They already had 9 eggs so adding 96 and 9 gives us 105 eggs in total

Answer:

3/5

Step-by-step explanation:

The numerator, 24, and the denominator, 40, both have a GCF(greatest common factor) of 8. By dividing both the numerator, 24, and the denominator, 40, by 8 you would be simplify the fraction. In which you'd get a numerator of 3 and a denominator of 5, which is 3/5 and the simplest form of 24/40.

The simplified form of 24/40 is 3/5.

To simplify the fraction 24/40, we need to find the greatest common factor (GCF) of the numerator (24) and the denominator (40) and then divide both the numerator and denominator by that GCF.

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24.

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40.

Looking at the lists of factors, we can see that the greatest common factor of 24 and 40 is 8.

To simplify the fraction, we divide both the numerator and denominator by 8:

24 ÷ 8 = 3

40 ÷ 8 = 5

Therefore, the simplified form of 24/40 is 3/5.

The simplified fraction represents the same proportion as the original fraction but is written in its simplest and most reduced form. In this case, 24/40 can be simplified to 3/5 by dividing both the numerator and denominator by their greatest common factor, which is 8.

y=2( x - [tex]2^{2}[/tex])-2

Step-by-step explanation:

Use the vertex form,  y=a(x - [tex]h^{2}[/tex])+k to determine the values of A,H,K

a=2
