A cell phone company recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June’s sales. If y represents July’s sales, which equation can be used to determine the sales in July?

Answer:

12k = 84 (Product means multiply)

k = 7

Step-by-step explanation:

12k = 84

12k ÷ 12 = 84 ÷ 12

k = 7

Answer:

K = 82

94-12=84

therefore k= 82 because, 12+82=94

Answer:

y = [tex]\frac{27}{x^2}[/tex]

Step-by-step explanation:

Assuming you require the equation of proportion.

Given y is inversely proportional to x² , then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex]

To find k use the condition if y = 3, then x = 3, that is

3 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )

27 = k

y = [tex]\frac{27}{x^2}[/tex] ← equation of proportion

Answer:

peters net income is 28,000

Answer:

Sean didn't finish the job. He painted 23/30 of the fence in two hours.

Step-by-step explanation

He didn't finish the job because 23/30 is not finished. It isn't finished because Sean is less than 23/30 of the way done. That doesn't seem done to me.

I got the fraction 23/30 by looking at the problem carefully. He painted 3/10 of the fence "less" than the first hour which was 8/15 of the fence. So that means we have to subtract 8/15 and 3/10 to get 7/30.

Now, we just figured out how much Sean painted in the second hour, and the question is asking what fraction of the fence did he paint in BOTH hours. Meaning we have to add the first and second hour to get the answer of 23/30.

                                Hope this helped! Have a great day!

No, he did not finish his job.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given, Sean paints 8/15 of a fence in 1 hour,

Sean paints 3/10 part less in the second hour So, fraction he paints in the second hour = 8/15-3/10 = 16-9/30 = 7/30

So,

Paint in 2 hours = 8/15+7/30 = 16+7 / 30 = 23/30

Hence, he did not finish his job.

Answer:

y = -4x + 17

Step-by-step explanation:

Using the slope intercept formula, we can see the slope of line p is ¼. Since line k is perpendicular to line p it must have a slope that is the negative reciprocal. (-4/1) If we set up the formula y=mx+b, using the given point and a slope of (-4), we can solve for our b or y-intercept. In this case it would be 17.

Answer:

16 feet

Step-by-step explanation:

We are told that:

Earl attaches a wire from the top of a 16-foot flagpole and stakes it to the ground

Therefore, we can conclude that the Length of the wire = Length of the flagpole

The length of the wire = 16 ft

Therefore, the wire is 16 feet long.

Balanced means both sides are equal.

Add the left side: there are 7 1's which equal 7

Adding the right side you have 2 + r

They have to equal each other so the equation is 7 = 2 + r

Answer:

The correct option is a. 8.75.

Step-by-step explanation:

Given:

f(x)=[2.5x] .............................. (1)

Where;

x = 3.5

The function can be evaluated by substituting x = 3.5 into equation (1), we have:

f(3.5) = 2.5 * 3.5

f(3.5) = 8.75

This implies the value of the function is 8.75. Therefore, the correct option is a. 8.75.

Answer:

The 4th option i.e. 'The terms in Pattern C are 2 more than the terms in Pattern D' is correct.

Step-by-step explanation:

Given the patterns

Pattern C: 4, 5, 6, 7, 8, ...

Pattern D: 2, 3, 4, 5, 6, ...

If we carefully analyze, it is clear that terms in the pattern C are 2 more than the terms in Pattern D.

In other words, if we add 2 in each term of the Pattern D, we will get the pattern C.

For example,

Pattern D: 2, 3, 4, 5, 6, ...

Now, add 2 in each term of Pattern D

i.e.

2+2 = 4

3+2 = 5

4+2 = 6

5+2 = 7

6+2 = 8

It is clear that we get the results 4, 5, 6, 7, 8 when we add 2 in each term of Pattern D.

As 4, 5, 6, 7, 8 represent Pattern C. Therefore, we conclude that the terms in Pattern C are 2 more than the terms in Pattern D.

Hence, the 4th option i.e. 'The terms in Pattern C are 2 more than the terms in Pattern D' is correct.

Answer:

4, 5, 6, 7, 8 when we add 2 in each term of Pattern D

Answer:

c = 12 * t

Step-by-step explanation:

The only equation that relates t and c would be the following...

c = 12 * t

This is because the total number of cubes that exist depends on how many available trays exist. Therefore, creating a positive correlation relationship between these two variables. Since each tray contains 12 cubes, 12 is therefore multiplied by the number of trays to get the total number of cubes. This means that the more trays available the more cubes that are created.
