Answer:

8 times

Step-by-step explanation:

<u>The volume of the prism:</u>

V = lwh

<u>If each of the dimensions is doubled, then the volume becomes:</u>

V₁ = 2l*2w*2h = 8lwh = 8V

The larger prism has 8 times greater volume

If f(x) = V7x + 31 , find f(0).

Arte-miy333 [17]

Answer:

f(0) = 31

Step-by-step explanation:

We are given the following function:

$f(x) = \sqrt{7x} + 31$

f(0).

This is the value of f when $x = 0$ . So

$f(0) = \sqrt{7*0} + 31 = \sqrt{0} + 31 = 0 + 31 = 31$

So f(0) = 31

Tell whether the given number is a solution of each question. ( Must show work for credit)

guajiro [1.7K]

Answer/Step-by-step explanation:

1. $9 = 2a + 3$ ; 3

Let's solve for a.

$9 - 3 = 2a$ (subtraction property of equality)

$6 = 2a$

$\frac{6}{2} = a$ (division property of equality)

$3 = a$

$a = 3$

Therefore, 3 is a solution to 9 = 2a + 3

2. $5n - (-30) = 5$ ; 7

$5n + 30 = 5$ (- × - = +)

$5n = 5 - 30$ (Subtraction property of equality)

$5n = -25$

$\frac{5n}{5} = \frac{-25}{5}$ (division property of equality)

$n = -5$

Therefore, 7 is not a solution of $5n - (-30) = 5$

3. $4.4r - 2.8 = 1.6$ ; 1

$4.4r = 1.6 + 2.8$

$4.4r = 4.4$

$\frac{4.4r}{4.4} = \frac{4.4}{4.4}$

$r = 1$

Therefore, 1 is a solution of $4.4r - 2.8 = 1.6$ .

If y varies directly as x, and y = 12 when x = 72, then what is the value of x when y = 3 ?

qwelly [4]

Answer:

x = 18

Step-by-step explanation:

difference between y = 12, x=72 is 6

so if y = 3 then multiply 3×6 = 18
