At an elementary school there are two fenced in areas on the playground. the small play area is 1 4 the area of the large play area. the total square footage of the two areas is 2000 ft2. what is the size of the small play area?

The size of the small play area is

Step-by-step explanation:

Let

x-----> the small play area

y-----> the large play area

we know that

----> equation A

----> equation B

substitute equation B in equation A and solve for x

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

c.   x=2.4cm

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.
