Answer:
AC = 
units²
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse AC is equal to the sum of the squares on the other 2 sides, that is
AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( take square root of both sides )
AC = ≈ 9.43 ( to 2 dec. places )
Answer:
B
Step-by-step explanation:
Given
Your family has a circular swimming pool.
The radius of the pool is 9 feet and and its depth is 4 feet.
Find out the volume of the pool.
To proof
As depth is given in the question that means the shape of the swimming pool
is cylinder.
Formula
where r = radius
h = height
now
radius of the pool is 9 feet and and its depth is 4 feet.
put all the values in the above equation
we get
use 3.14 to approximate pi
we get
= 1017.4 ( approx )feet²
Hence proved
0

Answer:
The inequality best represents the length of the femur that would suggest the woman had a height greater than 160 cm is:
f > 40
Step-by-step explanation:
Woman's height (cm): h = 60 + 2.5 f
Length of the femur (cm): f
Height greater than 160 cm:
h > 160
Replacing h by 60+2.5f in the inequality above:
60+2.5f > 160
Solving for f: Subtracting 60 both sides of the inequality:
60+2.5f-60 > 160-60
Subtracting
2.5f > 100
Dividing both sides of the inequality by 2.5:
2.5f/2.5 > 100/2.5
f > 40
Answer: The inequality best represents the length of the femur that would suggest the woman had a height greater than 160 cm is:
f > 40
