Answer:
There would be 168 girls and 252 boys
Step-by-step explanation:
40% or 0.40 x 420 = 168
420 - 168 = 252
Answer:
False
Step-by-step explanation:
The volume of a right cylinder is given by the formula:
And the volume if a oblique cylinder is <em>also</em> given by the formula:
Regardless of the height, if the radius are different, then the volume would not be the same.
Algebraically:
To solve this problem, we need to know that
arc length = r θ where θ is the central angle in radians.
We're given
r = 6 (units)
length of minor arc AB = 4pi
so we need to calculate the central angle, θ
Rearrange equation at the beginning,
θ = (arc length) / r = 4pi / 6 = 2pi /3
Answer: the central angle is 2pi/3 radians, or (2pi/3)*(180/pi) degrees = 120 degrees
<u>The commutative property is when you can change the order and it will be the same answer.</u>
<u>6 + 8 + 7 = 7 + 8 + 6</u> would be your answer.
