1st problem:
Use the Pythagorean theorem:
a^2+b^2=c^2
49+361=c^2
c^2=410
c=20.24
The answer is 20m

2nd problem:
First calculate the height using the Pythagorean theorem:
a^2+b^2=c^2
20^2+b^2=625 (i got 20 {radius} by half-ing the base edge length)
400+b^2=625
b^2=225
b=15

Next, solve for the volume:
V=a^2*h/3
V=40^2*15/3
V=1600*5
V=8000

The answer is the second choice or B.

What is the greatest common factor of 35b^2,15b^3 and 5b?

xz_007 [3.2K]

ANSWER

The greatest common factor is 5b.

EXPLANATION

The first expression can be rewritten as

$35 {b}^{2} = 5 \times 7 \times {b}^{2}$

The second expression is rewritten as

$15 {b}^{3} = 3 \times 5 {b}^{3}$

The third expression is

$5b = 5 \times b$

The greatest common factor is the product of the least powers of the common factors.

$GCF=5 \times b = 5b$

How to solve and graph this equation ?

crimeas [40]

Start by adding 2y so that the equation becomes 2y= -3x-4 then divide by 2 on both sides so it cancelled out. (This if for if your trying to get it in y=mx+b form)

length-10x

width-x

perimeter-2(l+b)

66=2(10x+x)

66-2=10x+x

64=11x

x=11/64
