Joannie lent $200 to her sister. Four years later, her sister repaid her in full with $228. What simple annual interest rate did
vodomira [7]

Ok, so lets convert all the percents into decimals to help us solve this problem

A 3.0%= 0.03

B 3.5%= 0.035

C 4.0%= 0.04

D 4.5%= 0.045

Now, we can multiply $200 by all the decimals we just converted to see which one will add up to $208

200*0.03= 6-------200+6=206 (this is not equal to 208 so it's not A)

200*0.035=7--------200+7= 207 (Still does not equal 208, so it's not B)

200*0.04= 8---------200+8=208 C is your answer

Btw John makes 9$ an hour and amber makes 8$ an hour. REMEMBER TO ANSWER IN MINUTES NOT HOURS.
yarga [219]
Hello there! Provided the information, we know that the nearest multiple of 8 and 9 has to be greater than 50. 8 and 9 do not go into 50.

$9 • 6 hours = $54

$8 • 7 hours = $56

There are 60 minutes in an hour, so we can multiply accordingly:

60 minutes • 6 hours = 360 minutes

60 minutes • 7 hours = 420 minutes

Your final answers are:

It will take John 360 minutes to earn $50.

It will take Amber 420 minutes to earn $50.

(P.S. It takes Amber one more hour to earn $50 than it does for John to earn $50.)

Hope this helps!

A plastic ball is filled with gel to make a stress ball. If the ball has a radius of 4 cm, how much
Dafna1 [17]

Answer:

267.947 cm^{3} of gel is required to fill the plastic ball.

Step-by-step explanation:

<em>The radius of the ball is given as 4 cm.</em>

<em>The gel is filled in the plastic ball, that means the gel occupies the volume of the radius.</em>

The volume of the sphere is given by the formula,

V = \frac{4}{3}(\pi)R^{3} , the R is the radius of sphere.

V = \frac{4}{3}(\pi)(4)^{3} = 267.947 cm^{3}

Thus, the volume of gel required to fill the plastic ball to make it stress ball is

267.947 cm^{3} of gel.
