I assume, that the number 120 is 100% - because it's the output value of the task.

If 120 is 100%, so we can write it down as 120=100%.

We know, that x is 25% of the output value, so we can write it down as x=25%.

Now we have two equations:

1) 120=100%

2) x=25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

120/x=100%/25%

Solution for what is 25% of 120:

120/x=100/25 

(120/x)*x=(100/25)*x - we multiply both sides of the equation by x 

120=4*x - we divide both sides of the equation by (4) to get x 

120/4=x 

30=x 

x=30

The answer is: 25% of 120=30

A box in the shape of a rectangular prism has a width that is 5 inches greater than the height and a length that is 2 inches gre

aliina [53]

The volume of the rectangular prism can be express in standard polynomial as follows:

x³ + 12x² + 35x

<h3>How to find the volume of a rectangular prism?</h3>

volume of a rectangular prism = lwh

where

l = length
w = width
h = height

Therefore,

let

height = x

width = x + 5

length = x + 5 + 2 = x + 7

Therefore,

volume = x(x + 5)(x + 7)

volume = x(x² + 7x + 5x + 35)

volume = x(x² + 12x + 35)

volume = x³ + 12x² + 35x

Find the exponential function P(t)=P0a^t where P(2)=5 and P(4)=10

asambeis [7]

Answer:

$P(t)=\frac{5}{2} \cdot (\sqrt{2})^t$

Step-by-step explanation:

$P(2)=5$ meants when $t=2$ , that the value for $P(t)$ is 5.

So this gives us this equation:

$5=P_0 \cdot a^2$

$P(4)=10$ meants when $t=4$ , that the value for $P(t)$ is 10.

So this gives us this equation:

$10=P_0 \cdot a^4$

So I take equation 2 and divide it be equation 1 I get:

$\frac{10}{5}=\frac{P_0 \cdot a_4}{P_0 \cdot a_2}$

Simplifying:

$2=a^2$

Since the base for an exponential function can't be negative then $a=\sqrt{2}$ .

So plugging into one of my equations I began with gives me an equation to solve for the initial value, $P_0$ :

$5=P_0 \cdot (\sqrt{2})^2$

$5=P_0 \cdot 2$

Divide both sides by 2:

$\frac{5}{2}=P_0$

The function is:

$P(t)=\frac{5}{2} \cdot (\sqrt{2})^t$
