Answer:

36√3 + 144

Step-by-step explanation:

Given that,

base of the pyramid is an equilateral triangle with sides = 12

Formula to calculate total surface area of pyramid

<h3>[Base Area] +  1/2 × Perimeter × [Slant Length]</h3>

Base Area

1/2 (height) (base)

1/2 (√12²-6²)(12)

6(6√3)

36√3

perimeter of base

sum of all sides = 12 + 12+ 12

                          = 36

slant height = √10²-6²

                     = 8

put all these values in the formula above

36√3 + 1/2(36)(8)

36√3 + 144

Total area for the pyramid with the equilateral base =

36√3 + 144

In homer run derby competition there were 32 home rinse hit out of 124 hits approximately what percent of hits were home runs
RoseWind [281]

Answer:

26% of hits were home runs.

Step-by-step explanation:

In homer run derby competition there were 32 home rinse hit out of 124 hits approximately.

We need to find what percentage of hits were home runs.

\text{Formula for percentage }=\frac{\text{Number of hit by home run}}{\text{Total number of hits}}\times 100

Number of home runs hit = 32

Total number of hit = 124

Now we calculate the percentage

\%=\frac{32}{124}\times 100\approx 26

Thus, 26% of hits were home runs.

The complement of an angle is 25 less than 3 times the angles itself. Find the measure of each
Semenov [28]

Answer: 28.75° and 61.25°

Step-by-step explanation:

A complementary angle equals 90°.

Let the measure of the angle be a

Therefore, its complement will be:

= 90-a.

The complement of an angle is 25 less than 3 times the angles itself can be written as:

90-a = 3a - 25

90 + 25 = 3a + a

115 = 4a

a = 115/4

a= 28.75

Since the angle is 28.75°, the complement will be:

= 90° - 28.75°

= 61.25°

The angles are 28.75° and 61.25°
