Jada has 12 library books checked out and Han has one third less than that. How many books does Han have checked out?

Answers

Hi there :)

So since they initially drank 50 gallons, half of that is 25 gallons. 50+25= 75, therefore they drank 75 gallons.

Jada has 12 library books and 1/3 of that is 4, because 12 divided by 3 is 4, so 12-4=8. That means Han checked out only 8 books.

Good luck with the rest of your assignment, have a good day/night!!

What is the value of the expression (2)^6?
pls help ​

Answers

Answer:

64

Step-by-step explanation:

2^6, or 2⁶, is two to the power of six.

Basically you multiply the bottom number (in this case 2) by itself as many times as the the number in the top right (in this case six)

2^6=2*2*2*2*2*2=64

Answer: 64

Step-by-step explanation:

2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 = 64

2 ⋅ 2 ⋅ 2 = 8

2 ⋅ 2 ⋅ 2 = 8

8 x 8 = 64

Marcin buys 7 rulers and 15 crayons for £7.
A ruler costs 12p more than a crayon.

Find the cost of one crayon.

Answers

Answer: 28 p



Explanation:

To solve this problem we're going to use an equation. First let's write down the information that we do know.Let's use (r) for ruler and (c) for crayon.
So 7 rulers and 15 crayons cost £7 (or 700 pennies) --> 7r + 15c = 700But we also know that r = c +12
So we can substitute c + 12 into the first equation where r is at the moment.
7(c+12) + 15c = 700
Now let's expand the brackets. We multiply 7 by c to get 7c and 7x12 t0 get 84
7c + 84 +15c = 70022c + 84 = 700 Here I'm going to take 84 away from both sides. 22c = 616
Remember this is a non calculator paper so we need to find an easy way of dividing 616 by 22.
616 divided by 22 is 28 so c = 28Each crayon therefore costs 28p

Answer: 28 p is the cost of one crayon.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Marcin buys 7 rulers and 15 crayons for £7.

A ruler costs 12p more than a crayon.

now,

To solve this problem we're going to use an equation.

First let's write down the information that we do know.

Let's use (r) for ruler and (c) for crayon.

So 7 rulers and 15 crayons cost £7 (or 700 pennies)

--> 7r + 15c = 700

But we also know that r = c +12

So we can substitute c + 12 into the first equation where r is at the moment.

7(c+12) + 15c = 700

Now let's expand the brackets.

We multiply 7 by c to get 7c

and 7x12 t0 get 84

7c + 84 +15c = 700

22c + 84 = 700

Here I'm going to take 84 away from both sides.

22c = 616

616 divided by 22 is 28

so c = 28

hence, Each crayon therefore costs 28p.

Answers

Answer:

Population.

Step-by-step explanation:

Population can be defined as a collection or set of units or entities from whom we got the data.

This ultimately implies that, a population is the larger set from which other units can be picked from.

Hence, a population is an entire collection of outcomes or objects from which we can obtain or collect data. For example, the number of new born babies in a hospital, a country and the total number of football players in a soccer league.

Population = Movies.

Subset (sample) = comedy movies, horror movies, romance movies, and action movies.
