2/9 of the students are in sixth-grade

a. How many sixth graders are there if the school has 90 students?

b. How many sixth graders are there if the school has 270 students?

Answers

Answer 1

Answer:

a. 20

b. 60

Step-by-step explanation:

For this problem you could want to multiply 2/9 and 90, to get the first one, and the second one by doing 2/9 times 270, and since 270 is 3 times as much as 90, you could just multiply your first answer by 3.

hope this helps!

2 4/16 = 2 1/4 lb

Step-by-step explanation:

The pointer is 4 of the smallest units above 2. There are 16 of those small units. Each 2 of those units is 1/8 pound, so when the pointer is on a multiple of 2 units, it is on a multiple of 1/8 pound. No guesswork is required to choose the correct weight to the nearest 1/8 pound.

2 4/16 = 2 1/4 lb . . . . the scale reading to the nearest 1/8 pound.

What is the volume AND surface area of this cube??

I will be marking brainliest

Answers

Answer:

The volume is 80 cube in

The surface area is 112 square in

Step-by-step explanation:

So the volume is length*height*width. 4*5*4 is 80 so the volume is 80 cube inches.

The surface area is actually really easy to calculate. First, you mulitply 5 and 4. you get twenty, but that is only for one side. The side that is parell to that side is aslo 20. Then you mulitply 4 and 5 again, beacuse there is another side that is 4 inches as well.  you would get 20 and the side that is parelle would get 20 inches as well. Then you add. 20 + 20 + 20 + 20 = 80.

4 times 4 is 16. and the side that is parelle to that is 16 as well. 16 + 16 = 32

80 + 32 = 112

Damon buys lumber worth $562. He gets a 20% contractor's discount. The sales tax is 6%. His credit card gives him 2% off. How much does he pay?​

Answers

Answer: $404.64 and 157.36 dollars to save

Step-by-step explanation:

Answer:  $467.05

Step-by-step explanation:

The price is $562

20% off = 562 - 20% of 562 = 562 - 0.2(562) = $449.60

 

6% tax = 6% = 6/100 = 0.06

449.60 + 0.06*449.60 = $476.58

2% off from credit card = 476.58 - 0.02(476.58) = $467.05

$467.05 is the answer

Answer:

Option B

Step-by-step explanation:

to find the answer, you're going to break the phrase into different parts

these parts would be "13 more than", and "the product of 4 and a number, n"

"13 more than" means that you are adding 13 to the pile, so algebraically, this would be written as "+13" or "13+"

"the product of 4 and a number, n" is one thing, but it can be broken down even further to "the product of" and "4 and a number, n"

"the product of" means a multiplication sign, I know this because the term for the answer of multiplying numbers is "product"

"4 and a number, n" means that it is one thing that includes 4 and n together, so this would create 4n

if you put this all together, you would get "4n + 13" or "13 + 4n", these are the same thing, just written in different orders

Answer:

x = 2, y = 5

Step-by-step explanation:

Given the 2 equations

y = - 2x + 9 → (1)

y = 4x - 3 → (2)

Substitute y = 4x - 3 into (1)

4x - 3 = - 2x + 9 ( add 2x to both sides )

6x - 3 = 9 ( add 3 to both sides )

6x = 12 ( divide both sides by 6 )x = 2

Substitute x = 2 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 4(2) - 3 = 8 - 3 = 5

Then x = 2, y = 5

The answer is x= 2, y = 5
