Answer:

C. 52

Step-by-step explanation:

You can simply subtract 540 from the total amount of points

2880-540=2340

and then you can divide that by the number of points she gets every time she shops on the website

2340÷45

Which would equal 52

So, C. 52 would be the correct answer.

Hope this helps!

Parker is laying pavers to build a patio in his backyard. Each square paver measures 2 feet on each side. He would like the pati
MatroZZZ [7]

Answer:

32 pavers

Step-by-step explanation:

step 1

Find out the area of one square paver

The area of a square is

A=s^{2}

where

s is the length side of the square

we have

s=2\ ft

substitute

A=2^{2}\\A=4\ ft^{2}

step 2

Find out the area of the rectangular patio

we know that

The area of a rectangle is

A=LW

we have

L=16\ ft\\W=8\ ft

substitute

A=(16)(8)\\A=128\ ft^2

step 3

Find out the number of pavers needed to build the patio

Divide the area of the rectangular patio by the area of one paver

128\ ft^2/4\ ft^{2}=32\ pavers

HOW is it helpful to write numbers in different ways?
Alisiya [41]
It is helpful to write them in different ways
some ways to write them are
1.fractions
2.decimals
3.squareroots (if applicable)

so it would be more helpful in an equation to leave 6/7 in fractional form if  you are going to manipulate it more, because 0.857142857142... is much harder to keep track of than 6/7


and sometimes, they want a percent which is easier to convert to from decimal form than from fractinoal form so ex  0.857142857142...=85.7% vs 6/7 to percent

sometimes there will be square roots and they are easier if left like that ex
√2=1.4142135623...
it would be easier to leav it in square root

it depends on the equation you are trying to solve, because different forms have different pros and cons, some are easier to work with in a certain form but not in another, sometimes, you will need to change between multipule forms during the same problem

1 saa<br> ite<br> 5. Count by tens. What is the<br> next number?<br> 20, 30, 40, 50,
OleMash [197]

Answer:

60

Step-by-step explanation:

I would assume you want the answer step-by-step:

We can count carefully and read the question again.

It is asking for us to count by tens or add ten to the most recent integer in the pattern.

In that case, we can see that our answer will by 50 + 10 = 60.

Also, note, that this question is not very intellectually challenging! Next time ask a question like "What do they mean when they say this?" If you don't understand the wording.
