Answer:

The ratio of their corresponding side lengths is equal to \frac{1}{3}

Step-by-step explanation:

step 1

<em>Find the scale factor</em>

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----> the area of the smaller solid

y----> the area of the larger solid

so

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

In this problem we have

\frac{x}{y} =\frac{16}{144}

substitute

z^{2}=\frac{16}{144}

square root both sides

z=\frac{4}{12} ------> scale factor

Simplify

z=\frac{1}{3}

step 2

<em>Find the ratio of their corresponding side lengths</em>

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

In this problem we have that the scale factor is equal to \frac{1}{3}

therefore

The ratio of their corresponding side lengths is equal to \frac{1}{3}

Each table in the cafeteria can seat 10 students.how many tables are needed to seat 40 students
Vitek1552 [10]
Hi there!

To solve this problem, we need to divide the total amount of tables by the amount of students:

40 / 10 = 4

So, we need 4 tables to seat 40 students. 

Hope this helps!

if the line AB with A(-1,5) and B(3,7) is perpendicular to the line CD WITH C(7,11) AND D(X,23). THEN X=?​
MissTica

Answer:

x=1

Step-by-step explanation:

slope AB = (7-5) / (3 - -1) = 2 / 4 = 1/2

slope CD = (23-11) / (x-7) = 12 / (x-7)  

12 / (x-7) = - 2  ... perpendicular to AB slope 1 = - 1/slope 2

-2 (x-7) = 12

-2x + 14 = 12

-2x = -2

x = 1
