Answer:

The value of x is \frac{7}{4}.

Step-by-step explanation:

It is given that the inverse variation equation is

xy=k                  ..... (1)

The value of y is 4 and the value of k is 7.

Substitute y=4 and k=7 in equation (1).

x\times 4=7

Divide both sides by 4.

\frac{x\times 4}{4}=\frac{7}{4}

x=\frac{7}{4}

Therefore the value of x is \frac{7}{4}.

Some students washed 24 cars in 2 hours. how many cars can they wash in 15 hours?
madreJ [45]
Answer would be 180 cars.

Reason being if you take 24 and divide that by 2 you will get 12 and 12 times 15 is 180 or you could also do 24 times 7 then add 12 to get the 180 also

The school band director has a budget $4,428.00 to spend on the band room, instruments, music, and uniforms. There are four sect
galina1969 [7]

Answer:

The amount of money left for each section to spend from the budget in additional costs if they follow exact of the options is

Option 1 - $497.5

Option 2 - $494.5

Option 3 - $500.5

The image to show the amounts to match to isn't attagged to the question, but these are the answers and they should be matched accordingly.

Step-by-step explanation:

We first calculate the amount left per section after following each of the options.

Budget $4,428.00

Option 1.

Repair and replace uniforms at $564.00 per section and spend $182.00 on music.

There are 4 sections, hence, total amount spent in this option:

4(564) + 182 = $2438

Amount of money left from the budget after spending = 4428 - 2438 = $1990

Amount left per section = (1990/4) = $497.5

Option 2

Repair and replace uniforms at $593.00 per section and spend $78.00 on music.

There are 4 sections, hence, total amount spent in this option:

4(593) + 78 = $2450

Amount of money left from the budget after spending = 4428 - 2450 = $1978

Amount left per section = (1978/4) = $494.5

Option 3

Repair uniforms at $287.00 per section, spend $856.00 for improving the acoustics in the band room, and spend $422.00 on music and repairing instruments.

There are 4 sections, hence, total amount spent in this option:

4(287) + 856 + 422 = $2426

Amount of money left from the budget after spending = 4428 - 2426 = $2002

Amount left per section = (2002/4) = $500.5

Deffense [45]

Answer:

3.5

Step-by-step explanation:

mean= 0+2+3+3+3+3+3+4+4+4+4+5+5+6=49

49÷14=3.5

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Anvisha [2.4K]

The answer is C, or 28.

You can plug the values into a regression calculator to find the equation. When you do this, you will get the equation y=18.001+0.3ln(x). When you substitue 19 in for y, you get that x is about 28.
