Answer:
Friend A pays $340 and friend B pays $510
Step-by-step explanation:
Let's call
x: payment of friend A
1.5x: payment of friend B
The sum of both payments must total $850, thus:
x + 1.5x = 850
Simplifying:
2.5x=850
x = 340
Now for friend B:
1.5x=1.5*340=510
Friend A pays $340 and friend B pays $510

Data Set A has a mean of 215 and a standard deviation of 35. Data Set B has a mean of 400 and a standard deviation of 12.
Which data set is more spread out?
Answer:
Data set A
Step-by-step explanation:
Data set A is the one that is more spread out.
The mean is the same as the average of a given sample. It is usually a measure of the central tendency of a data set.
Standard deviation is a measure of the spread of a given set of data.
The lower the value of the standard deviation, the more clustered around the mean a data is. Data is spread out if it has a higher value of standard deviation.Since data set A has a standard deviation of 35, it the most spread out.

hi! the total angle measure of a triangle is 180 degrees. so, all three angle measures must add up to 180.
6x+6x+8x=180
20x=180
x=9
now, plug in x=9 for angle ABC.
8(9)= 72
m<ABC= 72 degrees

Tiffany ate 1/4 of a pizza. If there were 16 slices of pizza to begin with, how many slices did Tiffany eat?
Answer:
Tiffany ate 4 slices of pizza

1/4 of 16 is 4
Tiffany ate 4 slices of pizza.
What is fraction?" Fraction is a representation of a part of whole object which is divided into equal parts."
According to the question,
Total number of pizza slices = 16
Part of pizza ate by Tiffany = 1 / 4

Find the equation of the line shown.
Given : A graph of linear equationis given to us.
To Find : The equation of the line .
Solution : Here we can see that the line passes through points ( 1 , 2 ) and ( 2 , 4). So , clearly here we can use Two - point form to find the equation of the line .
So , first point will be , ( 1 , 2 ) & second point will be ( 2 , 4 ) . So here ;
[tex]\sf x_1 = 1\: \& \:y_1 = 2[/tex][tex]\sf x_2 = 2\: \&\: y_2=4[/tex]Now , the two point form formula is :
[tex]\Large\boxed{\red{\sf \purple{\mapsto} y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)}}[/tex]
[tex]\tt:\implies y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]

Wilson paints 40% of a bookcase in 20 minutes.
How much more time will it take him to finish the bookcase?
Answer:
30 minutes
Step-by-step explanation:
The percentage rises up by 40% every 20 minutes and if we divide that in half he paints 20% in 10 minutes. Wilson needs to paint 60% more of the bookcase. 40% plus 20% is 60%. So we just add 20 with 10 to get 30 minutes.

When an article is sold at a discount of 10 %, a profit of Rs 8 is earned. If the same
article is sold without allowing a discount, there will be a profit of Rs 20. Find the cost price of the article.
Answer:
Market Price = MP
Cost Price = CP
P1 = (MP - 10%) - CP = Rs8
- CP = Rs8 - 0.90% MP
CP = 0.90 MP - Rs8
P2 = MP - CP = Rs20
- CP = Rs20 -MP
CP = MP - Rs20
0.90 MP - Rs8 = MP - Rs20
- 0.10% MP = - Rs12
0.10% MP = Rs 12
MP = Rs120p
CP = MP - Rs20 = Rs120 - Rs20 = Rs100.
The cost price of the item is Rs100.
