Rianda bought 32 apples. She set aside 25% to eat and divided the rest equally among 6 pies. How many apples are in each pie?

Answers

Firstly, you have to calculate the 25 percent of the 32 apples which is 32 x 0.25 = 8. So the leftover apples would be 32 - 8 = 24. Since she divided the rest equally among 6 pies, you have to divide 24 by 6, which is 4.
Therefore there are 4 apples in each pie.

There are 4 apples in each pie.

A 1350 kg car travels at 12 m/s. What is it's kinetic energy

Answers

energy is always transformed from one form to another

energy is not created nor destroyed

so when a car starts moving the chemical potential energy of the car is converted to kinetic energy

kinetic energy is the energy that moving objects possess

kinetic energy formula is as follows

Kinetic energy = 1/2 mv²

where m - mass

v - velocity

substituting these values

K.E = 1/2 x 1350 kg x (12 m/s)²

= 1/2 x 1350 x 144 = 97200 J

the kinetic energy of the car is 97.2 kJ

Hello!

A 1350 kg car travels at 12 m/s. What is it's kinetic energy ?

We have the following data:

m (mass) = 1350 kg

v (velocity) = 12 m/s

KE (kinetic Energy) = ? (in Joule)

Formula to calculate kinetic energy:

$\boxed{KE = (1)/(2) *m*v^2}$

Solving:

$KE = (1)/(2) *m*v^2$

$KE = (1)/(2) *1350*12^2$

$KE = (1)/(2) *1350*144$

$KE = (194400)/(2)$

$\boxed{\boxed{KE = 97200\:Joule}}\:or\:\boxed{\boxed{KE = 97.2\:kJ}}\Longleftarrow(kinetic\:energy)\:\:\:\:\:\:\bf\blue{\checkmark}$

Of the 216 students on the playground three-eighths are wearing white shoes how many children on the playground are not wearing white shoes

Answers

If 3/8 ARE wearing white schoes
Then 5/8 AREN'T wearing white shoes
because

8/8 - 3/8 = 5/8
8/8 is the same as 1

Therefore,
5/8 x 216/1 = y
If this is mental maths then,

You can cancel the 216 by 8 because the denominator of 5/8 is 8 to make 27

Therefore, the answer is 135

First, you need to turn 3/8 in to a decimal. You can do that by dividing 3 by 8. You should get .375 now multiply that with 216. you should get 81. That means 81 kids are wearing white shoes. To find how many are not wearing white shoe, subtract 81 from 216. That gives you 135. 135 students are not wearing white shoes.

Riverside Elementary School is holding a school-wide election to choose a school color. Five eighths of the votes were for blue, five ninths of the remaining votes were for green, and the remaining 48 votes were for red. How many votes were for blue? How many votes for green?

Answers

1) Write out what you know
Blue: 5/8
Green: 5/9 (of 3/8 because it is the remaining parts) so 5/24
Red: 1 - (5/8 + 5/24) = 1/6
2) Find the total amount of people
You know that 1/6 of the population is 48, so the total population is 288 (48×6)
3) Multiply the total population by the fractions to get the number of votes
Blue: 288 × 5/8 = 180 votes
Green: 288 × 5/24 = 60 votes

Check: 180 + 60 + 48 = 288 votes

Answer:

180
