A pet survey found that the ratio of dogs to cats is
2
5
. Which proportion shows the number of dogs if the number of cats is 140?

Ok so i hope this helps you.

There are 56 dogs when the number of cats is 140.

Step-by-step explanation:

The ratio of dogs to cats:

\frac{2}{5}

The other proportion:

\frac{x}{140}

\frac{2}{5} = \frac{x}{140}

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1

\frac{2}{5} * \frac{28}{28} = \frac{56}{140}

There are 56 dogs when the number of cats is 140.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
