There are 8 boxes of pasta on a shelf. Each serving of pasta is 1/6 of a box. How many servings of pasta are there in the boxes on the shelf?

Answers

Answer:

1 1/3 servings of pasta on the shelf.

Step-by-step explanation:

All you need to do is 8*1/6 because if there are 1/6 of a serving of pasta in each box and you have 8 boxes, then you need to multiply to find the number of servings.

8*1/6=1 1/3 or 1.(3)

(3) or any other number in parentheses next to a decimal means it's a repeating decimal, and it never ends.

Answer:

Step-by-step explanation:

Box=8

Serving=1/6 of 1 box

=6 servings

6 servings * 8= 48 servings

Number of servings= 48

There are 48 servings of pasta in the boxes on the shelf

NOTE: Angles not necessarily drawn to scale.

Answers

The entire plane is 360°
Each side (top & bottom) is 180°
Each 1/4 section is 90°
With the information given that the angle opposite to x is 77°
And the total angle of that quadrant is 90°
By using the laws of angles.

Then you can calculate 90°-77°=x
So x=13°

please help me out giving brainliest

I’m not sure how to solve the first one but the second one (c) is 24. You have to see the pattern between 15 and 45 and then do that to the denominators. The pattern is multiplying by 3 (15x3 =45) so multiply 8 by 3 and you get 24. Hope this helps and if not, please message me for further help.
For the first one, cross multiply 15 and c which is 15c and cross multiply 8 and 45 which is 360, so u get 15c = 360 and divide 15 c by 15 and 360 by 15 also then the answer would be c = 24

For the second one it’s basically the same thing, cross multiply x and 12 which is 12x and 8 and 3 which is 24, then you get 12x = 24. Divide both sides by 12 and the answer would be x = 2

A pair of Adidas running shoes has a regular price of $65.00. The shoes are on sale for 20% off. The sales tax is 8%. What is the TOTAL cost of the shoes including tax?

Answers

The price should be $57.20
The total should be $56.16

First, find how much how much 20% off of 65 would be.

20/100 • 65 = 13

So you have to subtract 13 from 65
65-13=52

So with the 20% discount the price will be $52.

Next find out how much the sales tax will be.
52 • 8/100 = 4.16

The sales tax is 4.16. Add the sales tax with the price of the shoes.
52 + 4.16 = 56.16

Therefore, the total including the sales tax is $56.16.

What is this (please)

Answers

Answer:

A) y=-4/5

Step-by-step explanation:

When you have two fractions equal to one another, the easiest thing is often to cross multiply. To do this, multiply the top of the left fraction by the bottom of the right fraction, and then multiply the bottom of the left fraction by the top of the right side and put them equal to eachother:

[tex]\frac{a}{b} = \frac{c}{d} \\ad=bc[/tex]

Knowing this, and some algebra, we can solve the question:

[tex]\frac{7y+4}{y+2} =\frac{-4}{3}[/tex]

(7y+4)(3)=(y+2)(-4)

21y+12=-4y-8

21y+4y=-8-12

25y=-20

y=-4/5

A) Y= -4/5
