5. Two similar figures have volumes 27 in.? and 125 in.?. The surface area of the smaller figure is 63 in.. (1 point)
GREYUIT [131]

Answer:

175\ in^{2}

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z----> the scale factor

x----> volume of the larger solid

y----> volume of the smaller solid

z^{3}=\frac{x}{y}

we have

x=125\ in^{3}

y=27\ in^{3}

substitute

z^{3}=\frac{125}{27}

z=\frac{5}{3}

step 2

Find the surface area of the larger solid

we know that

If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared

Let

z----> the scale factor

x----> surface area of the larger solid

y----> surface area of the smaller solid

z^{2}=\frac{x}{y}

we have

z=\frac{5}{3}

y=63\ in^{2}

substitute

(\frac{5}{3})^{2}=\frac{x}{63}

x=\frac{25}{9}*63=175\ in^{2}

Can someone explain this to me I need help T_T
vaieri [72.5K]

Answer: 6,800,000 people

Step-by-step explanation:

We are looking for the number of people, not the percentage of wealth that has been made up by the people.

2% of the people are the richest in the United States, and there are 340,000,000 people in total in the United States.

2% = 0.02

340,000,000 * 0.02 = 6,800,000

I hope this was helpful! :)

Which expression can be used to calculateof formalin needed make this batch of 3200 pd the amount? The batch sugar 3% water 39%
Anit [1.1K]

The appropriate expression to identify the amount of formalin is: x = 3200 ÷ 100 × 44%

<h3>How to identify the amount of formalin?</h3>

To calculate the amount of formalin in this substance we must perform the following mathematical operation:

  • 3200 ÷ 100 = 32
  • 32 × 44% = 1,408

According to the above, the mathematical expression would be:

  • X = 3200 ÷ 100 × 44%
