volume of the center sphere = 4/3*PI*r^3
r = 3 ( given in the picture)
so 4/3 * 3.14 *3^3 = 113.04 cubic feet
volume of 1 cone: pi *r^2 *h/3
r = 3 and h=3 ( given in the picture)
so 3.14 * 3^2 * 3/3 = 28.26 cubic feet
there are 4 cones so 28.26* 4 = 113.04 cubic feet
113.04 + 113.04 = 226.08 cubic feet
rounded to nearest cubic foot = 226 cubic feet
Easy! 1 hour - 1 hour and 30 minutes = 30 minutes(together)
Since u need the surface area of a rectangular prism it is length•width•height so the answer is 24 feet squared
Simple, since you want to find y, in y=mx+b form, move everything to the other side.
1/2x-y=4
Move 1/2x
1/2x-y=4
-1/2x -1/2x
Making it look like,
-y=4-1/2x
Divide by the negative 1 in front of the y,
-y=4-1/2x
/-1 /-1
y=-4+1/2x
or
y=1/2x-4
Thus, this written in y=mx+b form, y=1/2x-4.
Any number that ends with 0 or 5 is divisible by 5. If it ends with any other numbers such as 1 2, 3, 4, ,6, 7, 8, 9 then it is not divisible by 5. If a number is divisible by it means that the number can be divided by 5.
5, 10, 15, 20, 25, 1234567890, 9876543210, etc. are going to be divisible by 5 because they end or a 0.
So, look through your given options. Which answer choice has a 0 or a 5 at the end of the number? That's your answer. :)
Hope that helped. (:
