Hailey wants to hire someone to paint her house. She researched several independent painters who provided information about the

average amount of time it takes them to paint a certain number of square feet of wall space. The three painters with the top ratings are listed in the table below, along with the information they provided.
Name Area Painted
(square feet) Time
(hours:minutes)
Richard 288 45
Gerard 825 2:12
Matthew 992 2:35


Part A: Calculate the unit rate for each painter.

Part B: Compare each pair of painters (Richard with Gerard; Gerard with Matthew; Matthew with Richard), and state whether their rates are in a proportional relationship or not (and why) using their respective unit rates as evidence.

Determine of which lines, if any, are parallel or perpendicular. Explain.
nalin [4]

Answer:

lines b and c are perpendicular

Step-by-step explanation:

Use slope

slope for parallel is the same

slope for perpendicular is negative reciprocal

line a slope- 1-3/-2-0 is -2/-2 or 1

line b slope- 1-4/4-6 is -3/-2 or 3/2

line c slope- 3-1/1-4 is 2/-3 or - 2/3

none are the same so none are parallel

- 2/3 is the negative reciprocal of 3/2 so lines b and c are perpendicular

28% of 80 is what number?<br> a. 22.4<br> b. 2.24<br> c. 224<br> d. 24.4
Ratling [72]
X = 28% * 80

x = 28/100 * 80

x = 28/10 * 8

x = 2.8 * 8

x = 22.4


28% of 80 is 22.4.

Your final name is a. 22.4

8 times of the eight term of an arithmetic progression is equal to 12 times of the twelfth term. find its first term if the comm
denpristay [2]

Answer:

38

Step-by-step explanation:

We can express the 8th term as x and the 12th term as y.

This would mean that 8x=12y

Because the common difference between terms is -2 and term 8 and term 12 are 4 terms apart, this means that the 12th term is 8 less than the 8th term, so x-8=y

Now we can use this to substitute y with x in the first equation. This would give us:

8x=12(x-8)

Which we can expand and solve:

8x=12x-96

-4x=-96

Therefore x=24

This means the 8th term is 24 and the 12th term is 16 (24-8).

To test if this is correct we can do:

8x24=12x16

Which indeed are equal, both sides multiply to 192.

Now that we have our 8th term, we can find the 1st term, which is 7 terms away, therefore we just add 14 to the 8th term 24. (7x2=14)

24+14=38.

The first term is 38.

Hope this helped!
