Chloe scored 24 points over the first 12 games of the basketball season. She scored 112 points over the last 16 games of the season. How many more points per game did Chloe score in the last 16 games of the season?

Answers

Answer:

5 points

Step-by-step explanation:

First, find how many points per game she scored over the first 12 games:

24/12

= 2 points per game

Now, find how many she scored in the last 16 games:

112/16

= 7 points per game

Find the difference:

7 - 2

= 5

So, she scored 5 more points per game in the last 16 games

Answer:

first 12 games- 24/12= 2ppg

Last 16 games- 112/16= 7ppg

7-2= 5 points per game more

Function A and Function B are linear functions. Compare the two functions and choose all that are correct. Can someone help?

Answers

Answer:

(b) and (c) are true

Step-by-step explanation:

Given

Function A and B

First, calculate the slope of A

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{24 - -21}{8- -7}[/tex]

[tex]m = \frac{45}{15}[/tex]

[tex]m =3[/tex]

The equation of function A is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 3(x - 8) + 24[/tex]

[tex]y = 3x - 24 + 24[/tex]

[tex]y = 3x[/tex]

The general form of a function is:

[tex]y = mx + b[/tex]

Where [tex]m = slope[/tex] and [tex]b = y\ intercept.[/tex]

This implies that:

[tex]Slope = 3[/tex]

[tex]Y\ intercept = 0[/tex]

For function B:

[tex]y = 4x - 3[/tex]

[tex]Slope = 4[/tex]

[tex]Y\ intercept = -3[/tex]

By comparison:

(b) and (c) are true

The 3rd term of an arithinetic progression is-9
and the 7th term is -29. Find the 10th term of the
progression.​

Answers

Answer:

-64

Step-by-step explanation:

The computation of the 10th term of the progression is shown below:

The 3rd term is -9

A_n = a + (n - 1)d

-9 = a + (3 - 1)d

-9 = a + 2d

-9 - 2d = a

Now the 7th term is -29

A_n = a + (n - 1)d

-29 = a + (7 - 1)d

-29 = a + 6d

Put the a value to the above equation

-29 = -9 - 2d + 6d

-29 + 9 = 4d

-20 = 4d

d = -5

Now

-9 - 2d = a

-9 - 2(-5) = a

-9 - 10 = a

a = -19

Now finally the 10th term of the progression is

= a + (n - 1)d

= -19 + (10- 1)-5

= -19 -45

= -64

Henry bought a pair of shoes that were on sale for 25% off. The sale price of the shoes was $42. What was the original price?

Answers

Answer:

$56

Step-by-step explanation:

Find out the percentage of the pair of shoes after the sale discount.

100 - 25 = 75%

75% = 42

1% = 42 ÷ 75 = 0.56

100% is the percentage of the original price.

100% = 0.56 x 100 = 56
