Answer: 27/8 or 3 3/8

Step-by-step explanation:

For this problem, you can simply plug the side length, 2 1/2, into the variable, s. Let's change it to an improper fraction to make it an easier process. Plugging in the number would be: V=3/2^3. This would be translated to 3/2 x 3/2 x 3/2. Multiply them and you'll get 27/8 or 3 3/8.

Answer:

Number 3; Part A:

Megabyte - 0, 25, 50, 75, 100.

Seconds - 1, 2, 3, 4.

Number 3; Part B:

The problem says "A computer downloads songs at a ratio of 50 megabytes in 2 seconds." So, (ratio = 50:2 )...

50:2 = 25:1

-If your confused about part a or b, this is how I did pt. A...

First you have to find the pattern in the number line.

I can tell that the pattern is ×25.

-For part b, I divided the ratio (50:2) by 2.

Which gave me 25:1

Find a polynomial, which if substituted for M will make the equation an identity: (4c^4–7c^2+6)–M=0

Answers

Answer:
-3c^2+6
Step-by-step explanation:
The equation will be identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combing the c^2 terms.

The contents of parentheses simplify as follows: (4c^2 - 7c^2 +6)=(c^2(4 -7)+6)=(-3c^2 +6)

Answer:

It is -3c^2+6.

y=mx+b
Using ordered pair (900,1150)
Slope= 4/3

Solve for the y intercept

Answers

Answer:

the y intercept is -50

Step-by-step explanation:

in y=mx+b, m is the slope and b is the y intercept. We are given the point (900,1150) and a slope of 4/3

we can susbstitute 4/3 into the equation.

y=4/3x+b

since the line will go through the point (900,1150), we can plug it into the equation.

1150=4/3(900)+b

1150=1200+b

-50=b

we are left with the y intercept (b) being -50. As a point, it's (0,-50)

Hope this helps!

The y intercept is -50

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.

On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
sales

Answers

If we take the paycheck amount of $1020 and subtract it by the weekly salary of $300.

$1020 - $300 = $720

We get $720 in sale commissions. So to get the number of sales, you divide the $720 by the $40 per sale commission.

$720/$40 = 18

Therefore, the sales Salesman B has for the week is 18.

he had 18 sales for the week
