Answer:
Step-by-step explanation:
The volume of a cone is
Filling in what we have:
and simplifying a bit:
Multiply both sides by 3 to get:
Divide both sides by 12.56 to get:
and take the square root of both sides to find the radius:
r = 5
If the radius is 5 and the radius by definition is half the diameter, then the diameter is 10 inches.
Answer:
940800 different ways to create the committee.
Step-by-step explanation:
1 chosen from 100 leaves 98 to chose from on the second pick because the other senator from the same state is also eliminated. The second choice leaves 96 available for the third selection.
So multiply 100×98×96=940800
Rational numbers are sometimes natural numbers.
Answer:
D
Step-by-step explanation:
If you multiply 3 and 7 you are saying she worked 21 hours when she only worked a total of 10 hours.
This looks familiar, right? Like slope-intercept.
y=mx+b, where m is the slope.
Let's right it like that.
5y=3x-10 (add 3x to both sides, since we want to isolate the y.)
Now divide by 5, since - again - we want to isolate the y.
y= 3/5x-10/5 >>>> y= 3/5x-2
I think the slope is 3/5.
If the line happens to be parallel, the slope is the same. If perpendicular, it is opposite reciprocal. So if it was perpendicular, the slope would be -5/3.
