Answer:

PO = 11, LQ = 4, NQ = 12, perimeter of NLP = 24

Step-by-step explanation:

The centroid is the point where the medians intersect each other.

A median divides the side it intersects in 2 equal parts.

So, if NP = 11, then PO = 11

The medians of a triangle intersect each other in the ratio 2:1

So, if NL = 8, then LQ = 4 and NQ = 8+4 = 12

if ML = 10, LP = 5

Finally, the perimeter of the triangle NLP is

NL + NP + LP = 8 + 11 + 5 = 24

This question is a lot less complicated than it sounds: 
cost = c
amount of tickets = s

Since we know that each ticket costs 7$, we multiply the amount of tickets by 7. 
c = 7s

The 7 is an independent variable. It will always be multiplied by s, no matter what s is. 
The c is a dependent variable. Different numbers for s change what c is. 

Ryan and Sarah are looking at cell phone plans. A group plan will cost $120.95 per month. An individual plan will cost $62.77 per month. Should Ryan and Sarah purchase a group plant or two individual plans? Justify your answer. How much money could they save?

Answers

this is easy
each month they either pay
120.95 per month for 2 people
or
62.77 per month per person or 62.77 time 2 people

so find which is greater: 120.95 or 62.77 times 2

find 62.77 times 2
we find that it is 125.54

125.54 is greater than 120.95
therefor it is less cost to buy a group plan
the could save 125.54-120.95=4.59


answers:
group plan
save $4.59
A group plan because on that one they will pay 120.95 and in a individual plan they will pay 125.54 so in a group plan you pay 4.59 dollars less so thats why a group plan is the best option

Wallpaper was applied to one rectangular wall of a large room. The dimensions of the wall is 42 feet on one side and the other side 25.5 feet. If the total cost of the wallpaper was $771.12, what was the cost, in dollars, of the wallpaper per square foot?PLZ HELP ASAP!!!!!!!

Answers

Answer: $0.72


Step-by-step explanation:

Given The dimensions of the rectangular wall of a large room.

Length of the rectangular wall= 42 feet

Width of the rectangular wall= 25.5 feet

Then the area of the rectangular wall =length*\ width

=42*25.5=1071\ square feet

The cost of the wallpaper = $771.12

The cost of the wallpaper per square foot=\frac{\text{total cost of wallpaper}}{\text{area of the wall}}

=(771.12)/(1071)\n\n=(77112)/(107100)=(72)/(100)=\$0.72

Hence, the cost of the wallpaper per square foot = $0.72
.72¢ per square foot. 
In order to find this answer, first you need to find out how many square feet the wall is. Multiply the dimensions ( 42 x2 5.5), and that would give you the answer. (1,071). Now that we have the total square footage, you can cross multiply to find out how much 1 square foot would cost.    1,071       1

Cross multiply to get the answer .72
