Answer:
317.6 feet
Step-by-step explanation:
the length of the diagonal can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
280² + 150²
= 78,400 + 22,500
= 100,900
take the square root of 100,900
= 317.648 feet
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
317.6 to the nearest tenth
By the PEMDAS rule, as long as the stuff inside the parentheses add up to 42, it would be correct. Therefore:
A. Correct because 40 + 2 = 42
B. Correct because 20 + 22 = 42
C. Incorrect because 4 + 20 = 24 ≠ 42
D. Incorrect, because 4 + 2 = 6 ≠ 42
32/10 as a mixed number is 3 2/10
The volume of a square pyramid is equal to:
Volume = a^2 (h/3)
In order for us to get the height, we need to substitute the values.
<span>Volume = a^2 (h/3)
</span>960 = 12^2 (h/3)
960 = 144h/3
960 = 48h
h = 20 in.
So the height is equal to 20 inches.
