Luden [163]3 years ago
4 0

Answer:

Area = 30 in.

<h3>Step-by-step explanation:</h3>

the formula for an area of a trapezoid is A = (a+b)/2 × h

a = base (or bottom)

b = 2nd base (or top)

h = height

set up your equation as A = (10 + 5)/2 × 4

A = 15/2 × 4

A = 7.5 × 4

A = 30

The area of the trapezoid is 30 in.

After a storm, 135 trees out of 180 were left standing. What is the percentage loss of the number of trees?
beks73 [17]

Answer:

Percentage loss of the number of trees is 25\%.

Step-by-step explanation:

Given: After a storm, 135 trees out of 180 were left standing.

To find: What is the percentage loss of the number of trees?

Solution:

We have,

Total number of trees =180

Number of trees left standing =135

Therefore, loss of trees=180-135=45

We now that \text {Loss\%}=\frac{\text{Number of trees left}}{\text{Total number of trees}}\times 100 \%

\implies \text {Loss\%}=\frac{45}{180}\times 100 \%

\implies \text {Loss\%}=\frac{450}{18} \%

\implies \text {Loss\%}=25 \%

Hence, the percentage loss of the number of trees is 25\%.

If a math student Square both legs of a right triangle and the results were 441 and 400, what is the length of the hypotenuse of
kolezko [41]

Answer:

29 \\

Solution:

According to the Pythagorean Theorem, is that the square of the hypotenuse is equal to the sums of squares of the two legs in which if you take the square root of the sum you are going to get the actual length of the hypotenuse but the two legs are already squared so all you have to do now is sum them and take the square root of it.

\sqrt{441  +  400}  \\  \sqrt{841} \\ 29
