12. John borrowed $80 from his sister, Joan. He agreed to pay her back at a rate of $6 per

week. Create a function, P, that gives the amount of money that john still owes Joan after

w weeks.


12 (b) John told Joan that he will have paid her back all of the money, after making

payments for 13 weeks.. Explain why John is incorrect?

Answers

Answer 1

Answer:

P = 80 - 6w

Step-by-step explanation:

Initial amount = $80Payment each week = $6

Required function:

P = 80 - 6w

Time required to pay all money. At this time P = 0

0 = 80 - 6w6w = 80w = 80/6w = 13.33

Since w > 13, John needs 14 weeks

4. Elena's account balance with her parents is
-$5.50. She adds a certain amount of
money to her balance by mowing the lawn.
Elena now has an account balance less than
$20. Determine a possible amount she
earned mowing the lawn. Then interpret the
solution. (Example 1) moll end to bi

Answers

Answer:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Step-by-step explanation:

Ok, so the question says that Elena has -$5.50 in her account. That means that she owes someone ( the bank) $5.50.

Elena then mows the lawn which may have paid off her debt. But we don't know that for sure.

All they give us is that Elena has less than $20 in her bank account.

So your answer may look like this:

-$5.50>x>$20

Elena has more than -$5.50 but less than $20.

Elena earned, amount more than -$5.50 and less than $20 by mowing the lawn.

What is Inequality?

If two real numbers or the algebraic expressions are related by the symbols>”, “<”, “”, “”, then the relation is called an inequality.

For example, x>3 (x should be greater than 3)

Given,

Account balance of Elena with her parents = -$5.50.

Which means she is in debt of $5.50.

Elena then  adds a certain amount of money to her balance by mowing the lawn,

which may have paid off her debt, that is not sure.

But,

Account balance of Elena after mowing the lawn is more than - $5.50 less than $20.

Let the money Elena earned by Elena earned mowing the lawn  = x

Then,

Possible amount she earned mowing the lawn = -$5.50 < x <$20.

Hence, Possible amount Elena earned mowing the lawn is

between -$5.50 and $20 = -$5.50 < x < 20.

Answer:d

Step-by-step explanation:

What is Fraction?

A fraction is a mathematical representation of a part or parts of a whole. It consists of two numbers separated by a horizontal line, with the number above the line called the numerator and the number below the line called the denominator.

To convert a decimal to a fraction, we can use the place value of the decimal. In this case, Sharta's batting average is 0.583.

The decimal 0.583 can be expressed as a fraction by considering the digits after the decimal point.

The number 583 has three decimal places, so we can write it as:

= 0.583

= 583/1000

Therefore, the fraction that represents Sharta's batting average is 583/1000.

Answer:

Step-by-step explanation:

did school asignment

The measurement of ∠ B = 74°

What are Supplementary angles?

Two Angles are Supplementary when they add up to 180 degrees.

Given that ∠ A and ∠ B are Supplementary and ∠ A = (3x−23),

∠ B = (2x−12)

According to definition of Supplementary,

∠ A + ∠ B = 180°

(3x−23) + (2x−12) = 180°

5x - 35 = 180°

5x = 180° + 35

5x = 215°

x = 43°

Putting x = 43° in  ∠ B = (2x−12)

∠ B = (2*43−12)

∠ B = 86 - 12

∠ B = 74°

Hence, The measurement of ∠ B = 74°

Write an equation of the parabola that passes through the point (62,−490) and has x-intercepts −8 and 72. Then find the average rate of change from x=−8 to x=2.

Answers

Answer:

y =  0.7(x^2 - 64x - 576)

Average rate of change = -49.

Step-by-step explanation:

As the x intercepts are -8 and 72 we can write the equation

y = a(x + 8)(x - 72)     where a is some constant to be found.

As it passes through point  (62, -490) we have, substituting:

-490 = a(62+8)(62-72)

-490 =  - 700a

a = 0.7

So the equation of the parabola

y = 0.7(x + 8)(x - 72) or

y =  0.7(x^2 - 64x - 576).

Average rate of change between x = -8 and x = 2

=  [0.7(2+ 8)(2 - 72) -  0.7(-8+8)(-8-72)] / (2 - -8)

= -490 - 0 /10

= -49

Mrs. Phillips bought 1.5 pounds of ground beef from Kroger. She paid a total of $6.75 for the ground beef. What was the price per pound?

Answers

Answer:

Price per pound is $4.50

Step-by-step explanation:

Price per pound = $6.75 / 1.5lb = $4.50/lb

Answer:

Price per pound of ground beef is $4.5

Step-by-step explanation:

Price of 1.5 pounds of ground beef = $6.75

We need to find price per pound of ground beef.

Solving:

For finding cost of 1 pound of apples, we will divide cost of 1.5 pounds of ground beef by 1.5. i.e

Price of 1.5 pounds of ground beef = $6.75

Price of 1 pounds of ground beef = $6.75/1,5

                                                       = $ 4.5

So, price per pound of ground beef is $4.5

The Venn diagram represents the Quantum Physics High School student body. Circle A represents all students enrolled in extracurricular activities. Circle B represents all female students. There are 117 female students enrolled in extracurricular activities, and the enrollment of the high school is 1,000 students. There are 450 male students. How many female students are not enrolled in extracurricular activities?

A.
117
B.
433
C.
550
D.
883

Answers

Answer:

D

Step-by-step explanation:

From the total 1000 students, 450 are male, so 1000 - 450 = 550 students are female.

117 students are both [enrolled in extracurriculars] and [female].

The total number of [female] students is equal to the total number of [female AND enrolled] students plus the total number of [female AND not enrolled] students. The events of being enrolled in extracurriculars and not being enrolled are mutually exclusive. So if x is the number of female students not enrolled in extracurriculars, then

550 = x + 117

x = 550 - 117

x = 433

and the answer is B.
