63 can be your answer

Add the digits: 6 + 3 = 9

Round: 63, 3 is less than 5, therefore, round down. 63 rounded = 60

20 < 63 < 90

hope this helps

You have the be 63 for sure!

So, you're less than 90. I got that. Than, you're older than 20.

We than know that your age is rounded up to 60. So, if we do 9- 3 = 6.

Let's inverse that. 6+3=9 which means  . . . You're 63 years old. I'm sure you have a couple wrinkles by then! ;)

You are choosing between two plans at a health club. Plan A offers an initial membership fee of $75. And you pay $15 per month.
Dennis_Churaev [7]

Answer:

5 months

Step-by-step explanation:

Let the number of months equalising both plans fee = x

Plan A total fee = 75 + 15x , Plan B total fee = 20 + 26x

Equalise both: 75+15x = 20+26x ; 75-20 = 26x-15x ; 55 = 11x ; x = 55 / 11

x = 5  

Proof : 75 + 15 (5) = 20 + 26 (5) ; LHS 150 = RHS 150

A spherical balloon has a 34-in. diameter when it is fully inflated. Half of the air is let out of the balloon. Assume that the
jeka57 [31]

Answer:

a. 20,579.52 cubic inches

b.10,289.76  cubic inches.

c. 13.49 inches

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of a sphere:

Volume of a sphere: 4/3 π r³

Since diameter (d) = 2 radius (r)

Replacing with the value given:

34 =2r

34/2=r

r= 17 in

Back with the volume formula:

V = 4/3 π r³

V =4/3 π (17)³

V = 20,579.52 cubic inches

The volume of the half-inflated balloon is equal to the volume of the sphere divided by 2.

20,579.52/2 = 10,289.76  cubic inches.

To find the radius of the half-inflated balloon we have to apply again the volume formula and substitute v=10,289.76

10,289.76= 4/3 π r³

Solving for r

10,289.76/ (4/3 π)= r³

2,456.5 = r³

∛2,456.5 = r

r = 13.49 inches
