A baseball pitcher won 80% of the games he pitched. If he pitched 35 ballgames, how many games did he win?

Answers

Find 80% of 35.

0.80 * 35 = 28

So he won 28 games.

35 is the number of games he pitched, you need to find 80% of 35, to do so just change 80% into a decimal and multiply it to 35.

0.80 x 35 = 28

So he won 28 of his games.

btw :)

Answers

Answer:

n=56

Step-by-step explanation:

2/8=14/n

cross multiply

2*n=14*8

n=112/2

n=56

Answer:

n = 56

Step-by-step explanation:

Given

$(2)/(8)$ = $(14)/(n)$ ( cross- multiply )

2n = 112 ( divide both sides by 2 )

n = 56

What is 32 percent of 25

Answers

'is' in mathematics means equal
'of' in mathematics means multiplication

32% can also be written as 32/100

$x = (32)/(100) * 25$

$x = (32)/(4)$

$\boxed{\bf{x=8}}$

32% of 25 is 8

Convert percentage into decimal: 32%/100 = 0.32
Multiply the decimal by 25: 0.32 × 25 = 8 <-- our answer.

Use 3.14 to approximate pi and express your answer in hundredths.

Answers

find volume of each

volume of a sphere is 4/3 times pi times radius^3

so first calculate the smaler sphere
radius=6
pi is aprox 3.14
4/3 times 3.14 times r^3
4/3 times 3.14 times 6^3
4/3 times 3.14 times 216
904.32 cm^3=volume

volume of larger
radius=24
4/3 times 3.14 times 24^3
4/3 times 3.14 times 13824
57876.48 cm^3

so then subtract the volume of the smaller sphere from the larger sphere

57876.48-904.32=56972.16 cm

he used
56972.16 cm^3 plaster

I think you mean to the hundreth's place which is the place denoted by the x in 0.0x so it is to the hundreth's place
