1) Popcorn unit price: 17.57/7 = $2.51

2.51 x 3 = 7.53

Three bags of popcorn would cost $7.53.

2) Old games unit price: 73.10/5 = 14.62

14.62 x 6 = 87.72

If they sold six games they would've made $87.72.

3) Lollipop unit price: 20.51/7 = %2.93

2.39 x 4 = 11.72

Four lollipops would cost $11.72

4) Hotdogs unit price: 82.86/3 = $27.42

Hamburgers unit price: 55.12/2 $27.56

Hotdogs have the lower unit price. $27.42 < $27.56

5) Packs of paper unit price: 12.74/7 = $1.82

1.82 x 2 = 3.64

Two packs of paper would cost $3.64

Answer:

B. 15g^2 + 35g^3 - 45g

Step-by-step explanation:

5g(3g + 7g^2 - 9)

5 x 3 = 15 g x g = g^2; 15g^2

5 x 7 = 35 g x g^2 = g^3; 35g^3

5g x -9 = -45g

Answer: -11 5/8< -116/8

Answer:

1. -11[tex]\frac{5}{8}[/tex] > -11[tex]\frac{6}{8}[/tex]

2. |-11[tex]\frac{5}{8}[/tex]| > |-11[tex]\frac{6}{8}[/tex]|

Step-by-step explanation:

For 1: The greater the negative number, the less it's worth (if that makes sense). So, -11[tex]\frac{5}{8}[/tex] would be greater.

For 2: The absolute value (which is what the bars indicate) of -11[tex]\frac{5}{8}[/tex] is 11[tex]\frac{5}{8}[/tex], and the absolute value of -11[tex]\frac{6}{8}[/tex] is 11[tex]\frac{6}{8}[/tex]. So |-11[tex]\frac{5}{8}[/tex]|.

Hope that helps! :)

Answer: Rahul earns 3.5 dollars more per hour than Arun.

Step-by-step explanation:

17.3 is the slope of Arun's earnings. To find what Rahul makes in an hour, you can find the slope of his graph below.

Use the two points, (10,208) and (20, 416)

Use the formula for calculating slope:

416-208=208

20-10=10

---------------------

208/10= 20.8

Rahul's equation can be set up like this:

y=20.8x

Subtract:

20.8-17.3=3.5

Therefore, Rahul earns 3.50 dollars more per hour than Arun.

Answer: 2

Step-by-step explanation: This is incredibly simple first we can match the denominators, 4*13 = 52 and that means we have to do that to numerators to, 8x*4 = 32x so now our equation is 32x/52 = 64/52 and as we know 32*2 = 64 so that means x = 2.

Answer: D

Step-by-step explanation: -6 is less than 7

Answer:

I'm not sure, but I think is this

z=(82–86)/4 = -1

z=(90–86)/4= 1

P(82<x<86) = 0.34134

P(86<x<90) = 0.34134

P(82<x<90) = 0.34134+0.34134 = 0.68268

Answer: 12

Answer:The value of the given expression is -6.93

How to simplify the expression?

The expression in the question is given as:

negative 15 plus the quantity negative 3 and seven tenths plus 9 and 15 hundredths end quantity divided by 5 all times 3 squared minus 4 and 7 tenths

Rewrite the expression properly

So, we have

-15 - 3.7 + 9.15/5 * 3^2 - 4.7

Evaluate the quotient and the exponent

So, we have

-15 - 3.7 + 1.83 * 9 - 4.7

Evaluate the product

-15 - 3.7 + 16.47 - 4.7

Evaluate the sum and the difference

-6.93

Hence, the value of the given expression is -6.93 (none of the options is correct)

Answer:

1 spot back

Step-by-step explanation:

23 is closest to the number 24. 24 isn't divisible by 5 or 9 but it is by twelve. He Should only move 1 spot back because he is 1 in front of 24.

Answer: Diego is right and needs to go 1 place back.

Step-by-step explanation: We start by finding the least multiple for 5 it is 25, 9 is 27, and finally 12 is 24 and 24 is the closest so he only needs to back one place in line.

Answer:A. 33.814 ounces  B. 17 containers.

Step-by-step explanation:

Since there is only 33.814 USA fluid ounces (fl. oz) A is answered.

[tex]\frac{33.814}{1}[/tex] = 33.814

A. 33.814 ounces

Now that you need 2-ounce containters to fill with the 33.814 ounces (at this point you cant round to 34 ounces) how many cups do you need?

33.814/2 = 16.907 ounces (basicly 17 cups for the guests)

B. 17 containers.

Part A : The number of ounces in 1 liter is 33.814 ounces.

Part B  : The number of containers that can fit the sauce is 17.

Unit conversion is defined as expressing the same quantity by different measurement units.

For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.

Given that,

Amount of sauce for dipping mozzarella sticks = 1 liter

Part A :

We have the unit conversion,

1 liter = 33.814 ounces

Part B :

Measurement of containers = 2 ounces

Total amount of sauce = 33.814 ounces

We have to divide the total amount of sauce in to 2 ounce containers.

Number of containers formed = 33.814 / 2 = 16.907 ≈ 17

Hence there will be 17 containers of sauce.

Answer:

hello can you explain it a lil more pls

but i promise ill answer it

Step-by-step explanation:

Answer:

The answer is 3.

Step-by-step explanation:

So, 27 is equal to 3 times 3 times 3. How? 3 x 3 is 9, and 9 x 3 is 27. The question was asking you to find the number that when multipled by itself 3 times equals to 27. This is an easier question but if its a big number you can use a calculator.

Answer:

Check explanation

Step-by-step explanation:

With problems like these,

you need to find what number would be multiplied by 3 (the 'root index')

In this case, 3 can also be used,

3 x 3 x 3 = 27

It's a bit confusing but once you get the hang of it it becomes easier.

no other equations need to be done this is your answer:

[tex]\sqrt[3]{27}[/tex] = 3 x 3 x 3 = 27

_____

(in other problems there would be more steps,

the symbol is called a radical notion

The radicand is the number you are trying to reach (27 in this case)

the root index (3 in this case) is the number you use to find numbers that multiply *that* amount of times to equal the radicand.

3 can be multiplied 3 times to get 27

3 x 3 x 3 = 27

Hope this is clear!
