Teresa is a software engineer. Her base salary is $2400 and she makes $80 more for every copy of “Math is Fun”. Her total pay ,

P, (in dollars), after selling c copies is given by the following function.
P(c) = 2400 + 80c

1. What is Teresa’s total pay if she sells 22 copies?

2. If Teresa’s total pay is $5040, how many copies did she sell?

Answer:

1.) Teresa’s total pay if she sells 22 copies is $4160.

2.) If Teresa’s total pay is $5040, then she sold 33 copies.

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • Teresa is a software engineer. Her base salary is $2400.
  • she makes $80 more for every copy of “Math is Fun”.
  • P(c) = 2400 + 80c
<h3><u>To </u><u>Find</u>;</h3>
  • Teresa’s total pay if she sells 22 copies
  • If Teresa’s total pay is $5040, how many copies did she sell?
<h3>1.)</h3>

Teresa’s total pay if she sells 22 copies

P(c) = 2400 + 80c

P(22) = 2400 + 80(22) = 1760

P(22) = 2400 + 1760

P(22) = $4160

Thus, Teresa’s total pay if she sells 22 copies is $4160.

<h3>2.)</h3>

If Teresa’s total pay is $5040, how many copies did she sell?

Here,

Total pay – Teresa's salary = total pay after selling copies

$5040 – $2400 = $2640

Now, we know that she paid $80 for making every copy.

So,

2640 ÷ 80 = 33

Thus, If Teresa’s total pay is $5040, then she sold 33 copies.

Multiply 3/sqrt17- sqrt2 by which fraction will produce an equivalent fraction with rational denominator
zzz [600]

Answer:

B.

Step-by-step explanation:

To simplify something that looks like \frac{\text{whatever}}{\sqrt{a}-\sqrt{b}} you would multiply the top and bottom by the conjugate of the bottom. So you multiply the top and bottom for this problem I just made by:

\sqrt{a}+\sqrt{b}.

If you had  \frac{\text{whatever}}{\sqrt{a}+\sqrt{b}}, then you would multiply top and bottom the conjugate of \sqrt{a}+\sqrt{b} which is \sqrt{a}-\sqrt{b}.

The conjugate of a+b is a-b.

These have a term for it because when you multiply them something special happens.  The middle terms cancel so you only have to really multiply the first terms and the last terms.

Let's see:

(a+b)(a-b)

I'm going to use foil:

First:  a(a)=a^2

Outer: a(-b)=-ab

Inner:  b(a)=ab

Last:    b(-b)=-b^2

--------------------------Adding.

a^2-b^2

See -ab+ab canceled so all you had to do was the "first" and "last" of foil.

This would get rid of square roots if a and b had them because they are being squared.

Anyways the conjugate of \sqrt{17}-\sqrt{2} is

\sqrt{17}+\sqrt{2}.

This is the thing we are multiplying and top and bottom.

A basketball player makes 80% of her free throws. The random numbers below represent 20 trials for
Taya2010 [7]

Answer:

0.6

Step-by-step explanation:

  • The numbers 0 to 7 represent a made free throw
  • The numbers 8 to 9 represent a missed  free throw.

Given the simulation data

(8,2) (9,3) (4,0) (5,8) (2,7) (2,0) (5,4) (8,0) (0,4) (9.1)

(9,6) (6,5) (4,4) (1,7) (0,4) (8,5) (8,8) (1,7) (3,5) (0,3)

  • A pair that contains only numbers between 0 and 7 shows the player makes both throws.

These pairs are:

(4,0)  (2,7) (2,0) (5,4)  (0,4) (6,5) (4,4) (1,7) (0,4) (1,7) (3,5) (0,3)

There are a total of 12 cases where the player makes both throws.

Therefore:

P(Player makes both throws)=12/20=0.6

Find the unit rate 6 and 2/5 revolutions in 2 and 2/3 in seconds
Makovka662 [10]

<u>Step 1</u>

Convert mixed fractions into fractions

6 2/5 = (6*5)+2) / 5 = 32/5

2 2/3 = (2*3)+2) / 3 = 8/3

<u>Step 2</u>

32/5 ÷ 8 / 3 ; where 32/5 is the 1st fraction and 8/3 is the 2nd fraction

<u>Step 2 (A)</u>

Get the reciprocal of the 2nd fraction:

From 8/3 to 3/8

<u>Step 2 (B)</u>

Multiply 1st fraction to the reciprocal of the 2nd fraction

32/5 * 3/8 = (32*3) / (5*8) = 96/40

<u>Step 2 (C)</u>

Simplify the fraction

96/40 divide by 4 will become 24/10

24/10 divide 2 will become 12/5. The simplest fraction of 96/40

The unit rate is 12/5 = 2 2/5 revolutions per second
