Anthony has 400 marbles. He sells 1/4 of the marbles to Jayveon, he gives 10% to Abdul and donates 10 marbles to his little brot
Georgia [21]

Answer: See explanation

Step-by-step explanation:

Number of marbles = 400

Anthony sells 1/4 of the marbles to Jayveon. This will be:

= 1/4 × 400

= 100 marbles

Anthony gives 10% to Abdul. Abdul will have:

= 10% × 400

= 0.1 × 400

= 40 marbles

He gave 10 marbles to his little brother.

The number of marbles that Anthony has left will be:

= 400 - (100 + 40 + 10)

= 400 - 150

= 250 marbles

What is the volume of a sphere with a diameter of 15 cm? Round the answer to the nearest whole number.
AveGali [126]

Answer:

1767 cm³

Step-by-step explanation:

We can use volume V = 4/3 π r³

We have diameter of 15 cm. To get radius, we need to divide diameter by 2.

r = 7.5 cm

So now plug in r = 7.5 then calculate V:

V = 4/3 π ( 7.5 )³

V =  4/3 π * 421.875 ≈ 1767.145 ≈ 1767

Hope this helps.
