Answer:

Solve 14×1/5=n does not work

Step-by-step explanation:

Assuming you mean

4 ÷ 1/5=n

A Find out how many 1/5s are in 4.

That is correct. We are writing the division problem in words

B Solve 4×5/1=n.

We can copy dot flip

4 * 1/5=n

C Solve 1/4×1/5=n.

We do not flip the first term

D Solve n×1/5=4.

4 ÷ 1/5=n

Multiply each side by 1/5

4 ÷ 1/5 * 1/5=n* 1/5

4 = n*1/5

The surface areas of two similar figures are 25 in2 and 36 in2. If the volume of the smaller figure is 250 in3, what is the volu

Slav-nsk [51]

Since the figures are similar, we can establish a rule of three as follows.
We know that the area of the smaller figure is $25in^{2}$ , and its volume is $250in^{3}$ . We also know that the area of the larger figure is $36in^{2}$ ; since we don't now its volume, lets represent it with $X$ :
$\frac{25in^{2}----\ \textgreater \ 250in^{3}}{36in^{2}----\ \textgreater \ Xin^{3}}$
$\frac{25}{36} = \frac{250}{X}$
$X= \frac{(250)(36)}{25}$
$X=360$

We can conclude that the volume of the larger figure is $360in^{3}$ ; therefore, the correct answer is a.
