$7.25 for 5 liters

Step-by-step explanation:

If you get the unit rate of $4.47 for 3 liters it is 1.49 per liter.

1.49 x 5 = 7.45

Therefore, $7.25 for 5 liters is a better deal than $7.45 for 5 liters.

The product of 45 and the counting number n is a perfect cube. find the least possible value for n.
PLS HELP.

Answers

I agree that the answe is 45

The counting number n is 75 which when multiplied with 45 gives perfect cube.

What is a perfect cube?

Numbers which are the triple product of the exact number are known as perfect cubes.

In other words, we can say the value produced by multiplying a whole number by three times itself is a perfect cube.

A number that may be expressed as three times the product of another integer is also termed as a perfect cube.

It is given in the question that the product of 45 and the counting number n is a perfect cube
So, we have to find the counting number n

First of all we will factorise 45

45 = 5 × 9

After factorising we get,

45 = 3×3×5

For 45 to become perfect cube we have to multiply the factors with 3×5²

45 = 3×3×3×5×5×5

∴ 3×5² = 75

Hence , the counting number n is 75 which when multiplied with 45 gives perfect cube.

I DONNT UNDDERSTAND THIS AT ALL

Answers

Answer:

Here's exactly what I would write:

a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies, d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies

a = 4d

b = 3e

c = 2f

Expression for Sandy: 4d + 3e + 2f

Expression for Sandy and Nina: 5d + 4e + 2f

Step-by-step explanation:

This is a terrible question that makes people feel frustrated. I'm sorry.

a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies,

d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies

Sandy has 4 times the number of cupcakes as Nina: a = 4d

Sandy has 3 times the number of gummy bears as Nina: b = 3e

Sandy has 2 times the number of brownies as Nina: c = 2f

An expression for how many desserts Sandy is bringing: a + b + c

An expression that could be used for how many desserts Sandy and Nina are bringing together: a + b + c + d + e + f, but I think they want you to substitute the equivalent values like above (a = 4d)

Sandy: 4d + 3e + 2f

Sandy and Nina: 5d + 4e + 2f

because 4d + 3e + 2f + d + e + f = 5d + 4e + 2f

I'm sorry I don't have a simpler way to explain this. It's a painful question. I will answer any questions  you have.

Step-by-step explanation:

2. 8/15 + 2/5 = 14/15

since the directions say to estimate the answer is 1.

it is not 0 because it is not 1/15 etc

it is not 1/2 because it isn't 7.5/15

it is 1 because 14/15 is just one off from 15/15 which is equal to 1

Harper only has $15 to spend at the grocery store. She buys Doritos that cost $2 per bag and one sandwich for $8. Which solution set would represent the options for the number of bags of Doritos she can buy.

Answers

Answer:

2x + 8 ≤ 15

Step-by-step explanation:

Hi,

2x represents the cost for each bag of doritios. The 8 is the cost of the sandwitch. And 15 is how much money she can spend :)

Answer:

2d + 8 ≤ 15

Step-by-step explanation:

Let the amount of Doritos bags be represented by d.

2d + 8 ≤ 15

With this, we can solve.

2(3) + 8 ≤ 15

6 + 8 ≤ 15

14 ≤ 15

The equation is true, and we cannot go any further.

The answer is ≤ 3.

Hope this helps. Have a nice day.
