Step 4: SImplify. a > 336

What is the answer? 6.3 = 0.7x

Answers

Answer:

x = 9

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 0.7 from both sides:

6.3 = 0.7x

(6.3)/0.7 = (0.7x)/0.7

x = 6.3/0.7

x = 9

x = 9 is your answer.

Ben can type 150 words in 3 minutes. how many words can he type in 2minutes

Answers

Ben can type 100 words in 2 minutes. Since 50 can go into 150 three times, you do 50 x 2 which is 100 words in two minutes.
the answer would be 100.
this is because ben is most likely to type words in an equal amount of time. 
you can solve this by first finding how many words ben can type in ONE minute. this results in division or 150 divided by 3 which gives 50.
since the question is asking about TWO minutes, you add 50 two times or multiply 50 by 2 which will either way give you 100

- - Solve:

To find the volume of a sphere:
 (4)/(3) *3.14*R^3

3.14≈π

Now since its telling us to use π, then we do our formula by multiplying by π.

π=3.14 (Approximate amount)

So:

4/3*3.14*9^3=3052.08

So you are correct.

When Radius=9, you plug in for R. :)

Yes your answer is correct.
9 = R , for radious
Sphere Formula = s = 4,  Pi r  powered by 2  , volume below :

Volume of a sphere = V = (4/3)x(3.14)x(r^3)

now we have to multiply by pi = 3.14 which gets us 
3052.08    |  in powered by 3

so again yes you were right
