Answer:

8 inches.

Step-by-step explanation:

In the first bounce, the height that the ball reaches was 125 inches.

If the ball always bounces back to \frac{2}{5} of the height, then after 2nd bounce it will reach (125 \times \frac{2}{5}) = 50 inches height.

Again, after 3rd bounce, it will reach (50 \times \frac{2}{5}) = 20 inches height.

And, after 4th bounce, it will reach (20 \times \frac{2}{5}) = 8 inches height. (Answer)

How do I convert these probs? into base 10 4120_7, A3B_12, WXYZ_36
natali 33 [55]

4120_7 = 4•7³ + 1•7² + 2•7¹ + 0•7⁰

4120_7 = 4•343 + 1•49 + 2•7 + 0•1

4120_7 = 1372 + 49 + 14

4120_7 = 1435

In base 12, we use the digits 0-9 as well as A for 10 and B for 11. So

A3B_12 = 10•12² + 3•12¹ + 11•12⁰

A3B_12 = 10•144 + 3•12 + 11•1

A3B_12 = 1440 + 36 + 11

A3B_12 = 1487

In base 36, we assign values between 10 and 35 to the letters A-Z, so that

WXYZ_36 = 32•36³ + 33•36² + 34•36¹ + 35•36⁰

WXYZ_36 = 32•46656 + 33•1296 + 34•36 + 35•1

WXYZ_36 = 1492992 + 42768 + 1224 + 35

WXYZ_36 = 1537019

The radius of a sphere is 3 inches. Which represents the volume of the sphere?
uranmaximum [27]

Answer:

volume of sphere  =  113.14inches³  or  

      36πinces³

Step-by-step explanation:

given the radius of a sphere = 3inches

volume of the sphere = ?

π = 3.14v 0r 22/7

 recall, the formula for finding the volume of a sphere is given to be = 4/3 πr³

so,

volume of sphere  =   4/3 πr³

volume of sphere  = 4/3 ×  22/7 ×  ( 3)³

volume of sphere  =  4/3 × 22/7 × 27

volume of sphere  =  (4 × 22 × 9)/7

volume of sphere  =  113.14inches³  or  36πinces³

If the quotient of a number and 16 is added to 1/4 the result is 5/16
Molodets [167]

Answer:

if youre trying to find the number then the number is 1

Step-by-step explanation:

the equation would be x/16+1/4=5/16

well we want to make everything have the same denominator and 16 is the LCD ( least common denominator ) so you would multiply 1/4 by 4/4 to get 4/16.

this means x/16+4/16=5/16 and and 4+1=5 so 1 is the answer
