_____________________
The volume of a sphere is 2/3 of the volume of a cylinder with same radius, and height equal to the diameter. The volume V of a sphere is four-thirds times pi times the radius cubed. The volume of a hemisphere is one-half the volume of the related sphere.
Answer:
D
Step-by-step explanation:
A is an arithmetic sequence in that is adds or subtracts the same amount.
B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year
C is a geometric sequence because it's losing 5× however many questions missed
D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.
Answer:
m∠R = 39 degrees
Step-by-step explanation:
As complementary angles add up to 90 degrees, we can set up an equation to get x then find the measure of ∠R:
m∠R + m∠S = 90
2x+7+4x-13=90
6x+7-13=90
6x-6=90
6x=96
x=16
Since m∠R = (2x+7), 2x+7 would be 2(16)+7 or 39 degrees. So in conclusion, m∠R = 39 degrees
Answer:
120 feet
Step-by-step explanation:
Length/height =second number in ratio (here's it is 12)
L/10=12
Therefore length will be 120
