Answer 1
Answer:

Answer:

V =12.167 cm^3

Step-by-step explanation:

V = s^3 is the volume of a cube where s is the side length

The side length of the cube is 2.3 cm

V = ( 2.3  cm) ^3

V =12.167 cm^3
Answer 2
Answer:

Hey there!

The FORMULA:

V = s^3

Your EQUATION:

v = 2.3^3

SOLVING for the EQUATION

v = 2.3^3

2.3^3 = v

(2.3 cm)^3

≈ 2.3 cm * 2.3 cm * 2.3 cm

≈ 5.29 cm * 2.3 cm

≈ 12.167 cm^3

v ≈ 12.167 cm^3

Therefore, your answer is: 12.167 cm^3

Good luck on your assignment and enjoy your day!

You would like to buy a gaming system. The cost of the system is $500 and thecost of internet access is $40 per month.

Answers

This question has no direct question, so here are some facts if you want them:

This equation can be expressed as a linear equation.

The equation can be expressed as: y =40x + 500

The y-intercept is 500, and the slope is 40.

If you type in a graphing website like desmos, then you can actually graph the line if you wanted (or needed) to.

I'm not really sure what the question is, but maybe if you needed help, here you go.

Final answer:

To calculate the total cost of the gaming system and internet subscription, add the one-time cost of the gaming system to the monthly cost of internet access multiplied by the number of months.

Explanation:

This problem pertains to calculating ongoing costs over a period of time, often referred to as monthly expenses. The one-time cost of the gaming system is $500. After purchasing the system, you would incur a recurring cost for internet access which is $40 per month.

If, for example, you wanted to calculate your total cost for one year (12 months), you would begin with the initial $500, then add $40 multiplied by the 12 months: $500 + ( $40 * 12 ) = $980. This method applies to any number of months you want to calculate.

No responses yet... John is making trail mix based on a recipe that combines 6 cups of nuts with 5 cups of granola. John has 36 cups of nuts. How many cups of trail mix (total) does he have?

Answers

Given:

A recipe combines 6 cups of nuts with 5 cups of granola.

John has 36 cups of nuts.

To find:

Number of cups of trail mix (total) does he have.

Solution:

The recipe combines 6 cups of nuts with 5 cups of granola.

The recipe combines 1 cup of nuts with (5)/(6) cups of granola.

The recipe combines 36 cup of nuts with 36* (5)/(6) cups of granola.

So, the number of cups of granola in trail mix is

Granola=36* (5)/(6)

Granola=6* 5

Granola=30

Total number of cups = cups of nuts + cups of granola.

                                    =36+30

                                     =66

Therefore, the total number of cups in trail mix (total) he have, is 66.

What does mean stand for

Answers

When you add numbers together  and you divide it by the number of numbers you added is your mean. Like if you get  a 90 and 91  You add them  and divide it by 2 and that will be your mean. 
If you have a set of numbers, add all the number up and divide them by how many numbers you have. Hope that helps!:)
