List the prime factors of each number.Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
GCF and common factors are pretty much the same thing. GCF focuses only on the largest common while common focuses on them all.

Answer:

Step-by-step explanation:

volume of a cylinder=πr^2*h

226.2=3.14*8*r^2

226.2=25.12*r^2

226.2/25.12=r^2

9=r^2

$\sqrt{9$ =r

3=r

radius =3 feet

IM GIVING OUT BRAINLIEST!!!<br><br> 9*8+2+4=_______

inn [45]

We use the Order of Operations here.

Parentheses

Exponents

Multiplying

Adding

Dividing

Subtracting (PEMDAS)

And if both are there, we work left to right.

In the process we multiply first, then add left to right..

So,

9 * 8 + 2 + 4

= 72 + 2 + 4

= 74 + 4

= 78.

Which ordered pair (x, y) is the solution to the given system of linear equations?

QveST [7]

Answer:(-1,0)

Step-by-step explanation:

3x + 3y=-3. Solve by the elimination method.

-2x+y=2

2(3x + 3y)=-3(2) New equation 6x + 6y=-6

3(-2 + y)=2(3). New equation -6x +3y=6

9y= 0

y=0

6x +6(0)=-6

6x =-6

X=-1

Solve the proportion for the variable given.

xxMikexx [17]

Answer:

A) -50

Step-by-step explanation:

The given proportion relation is

$\frac{r + 10}{4} = \frac{r}{5}$

The least common denominator is 20

We multiply through by 20 to get

$20 \times ( \frac{r + 10}{4}) = \frac{r}{5} \times 20$

We simplify to get;

$5(r + 10) = 4r$

Expand the parenthesis to get:

$5r + 50 = 4r$

$5r - 4r = - 50$

This simplifies to

$r = - 50$
