Volume of a sphere formula is: V=4 /3 πr^3

You know v=17000 and pi=3.14

17 000 = 4/3 x 3.14 x r^3

(divide 17 000 by 4/3 x 3.14 ) --> r^3 = 4060.51 (2dp)

(cube root is to get just r) r = 15.95 inches (2dp)

There 15 inches to the nearest inch.

Hope this is correct! :D

R^2+(ab)^2= (ao)^2
ab=6
ao=11.7

Plug in

r^2+6^2=11.7^2

simplify

r^2+36= 136.89
-36 both sides

r^2=100.89
square root both sides

r= 10.04 rounded 10

Anybody...Help!!!!!!!!!!!

Sloan [31]

Simple...

when they ask for the rate of change they ask for slope -->>

Using $\frac{ y_{1} - y_{2} }{ x_{1} - x_{2} }$ to find the rate of change for (-3,0) and (-2,-5)

$\frac{0--5}{-3--2}$

$\frac{0+5}{-3+2}$

$\frac{5}{-1}$

m=-5

Thus, your answer.

Can somebody helppp ??

Answer:

Step-by-step explanation:

Since F is the midpoint of EG, EF and FG are equal. We know that FG is 4 units, so EF must be 4 units. We also know that FH and EF make EH, so we substitute the values that we have.

FH + EF = EH

6 + 4 = EH

EH = 10

Mr. Simpson is buying jerseys for his High School football team. Thejerseys cost $0 each and there is a processing fee of $65 to

Rina8888 [55]

ANSWER

The linear equation is: y = 80x + 65

Te cost for 40 football jerseys: $3265

EXPLANATION

Let 'x' be the number of jerseys and 'y' the cost of x jerseys.

Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.

Therefore, the cost 'y' of x jerseys is:

$y=80x+65$

Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:

$\begin{gathered} y=80\cdot40+65 \\ y=3200+65 \\ y=3265 \end{gathered}$

Help with my algebra homework

Maru [420]

Let's solve your equation step-by-step.

2x /5 + 3 = x/10 - 1

Step 1: Simplify both sides of the equation.

2x /5 + 3 = x/10 - 1

2/5x + 3 = 1/10x - 1

Step 2: Subtract 1/10x from both sides.

2/5x + 3 - 1/10x = 1/10x - 1 - 1/10x

3/10x + 3 = -1

Step 3: Subtract 3 from both sides.

3 /10x + 3 - 3 = -1 - 3

3/10x = -4

Step 4: Multiply both sides by 10/3.

(10/3) * (3/10x) = (10/3) * (-4)

x = -40/3
