Answer:
262 in
Step-by-step explanation:
the equation for volume of a sphere is : 
r
so replacing the number of the radius into the equation, it would look like:

r
which gives you 523.59878 in
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in
9514 1404 393
Answer:
True
Step-by-step explanation:
It is the sum of numbers having a common difference. The fact that it is a sum makes it a series (as opposed to a sequence, which is just a list of numbers). The common difference (of 2.5) makes it an arithmetic series.
True, the sum is an arithmetic series.
Answer:
im so so so sorry, but i dont know(possibly because im only in 7th grade with a sucky teacher)
Step-by-step explanation:
of a single roll . Mr. Hanky have 5 roll so Total Area =
. So ,
paper does Mr. Hanky have
<u>Step-by-step explanation:</u>
Here we have , Mr. Hanky has 5 rolls of butcher paper. If you roll out a whole roll the paper would measure 510 yards long. If the paper is 1.8 yard wide .We need to find that how many total square feet of paper does Mr. Hanky have . Let's find out:
We know that when butcher paper will be unfolded it will be in form of a rectangle with dimensions as :

So , Area of rectangle = 
⇒ 
⇒ 
⇒ 
But , 
⇒ 
⇒ 
Therefore ,
of a single roll . Mr. Hanky have 5 roll so Total Area =
. So ,
paper does Mr. Hanky have .
Y = -x + 4
y = 3x + 3
3x + 3 = -x + 4
3x + x = 4 - 3
4x = 1
x = 1/4
y = 3x + 3
y = 3(1/4) + 3
y = 3/4 + 3
y = 3/4 + 12/4
y = 15/4
solution is (1/4,15/4)
so line y = -x + 4 intersects the line y = 3x + 3 at (1/4,15/4)
