Answer:

24.9 meters to the nearest tenth.

Step-by-step explanation:

We have 2 similar triangles here so:

21/8 = h/9.5

h = 21* 9.5 / 8

= 24.94 m = the height of the tank.

Answer:

\boxed{24.9375}

Step-by-step explanation:

→ Write out the direct proportion equation

y = kx

→ Substitute in x = 21 and y = 8

8 = 21k

→ Divide both sides by 8 to isolate k

k = 2.625

→ Substitute back into original equation

y = 2.625k

→ Substitute 9.5 for k

y = 2.625 × 9.5 ⇔ 24.9375

What is 87 24 over 25 as a decimal
erastova [34]
8724/25 = 348.96
 When you say "over" that means that it has to be divided that short subtraction sign that separates the numerator and the denominator and also means divide so I believe that if you divide you can find the decimal.

vovikov84 [41]

Answer:

≈ 0.2526

Step-by-step explanation:

<u>The number of combinations of 4 out of 8:</u>

  • 8C4 = 8!/(4!(8-4)!)= 8*7*6*5/(1*2*3*4)= 70

<u>Success factor is: </u>

  • 57% = 0.57

<u>and failure factor is: </u>

  • (100 - 57)%= 43%= 0.43

<u>Probability:</u>

  • 0.57⁴*0.43⁴*70 ≈ 0.2526

A new building in the shape of a square pyramid is to be constructed. The slant height will be five times the side length of the
Temka [501]

The area of the square pyramid building is the amount of space on it

The maximum base length of the building is 67.42 cm

<h3>How to determine the maximum side length?</h3>

The given parameters are:

Base = b

Slant height (l) = 5b

The lateral surface area is calculated using:

L = 2bl

So, we have:

L = 2 * b * 5b

Evaluate the product

L = 10b^2

The total surface area is calculated using:

T = L + b^2

So, we have:

T = 10b^2 + b^2

Evaluate the sum

T = 11b^2

The maximum surface area is 50,000 square feet

So, we have:

11b^2 = 50000

Divide both sides by 11

b^2 = 50000/11

Take the square root of both sides

b = 67.42

Hence, the maximum base length of the building is 67.42 cm
