The Painter siblings, Elsa, Ben and Cal paint houses. They have been in the business so long that each knows exactly how many square feet each other paints in one hour and these rates never change. For their latest job, they calculated that if Elsa and Ben did the job together, it would take exactly 11 hours. On the other hand, if Elsa and Cal did the job together, it would take exactly 9 hours. Finally, Ben and Cal could do it in exactly 9.9 hours (or if you prefer, 9 hours and 54 minutes). They decided all three would paint this particular house. Ben and Cal started the job at 8 AM and Elsa joined them at 9:00. Cal left at 1:30 and so Ben and Elsafinished the job. After deducting the supply costs (paint etc.), the brothers split the net profit based on what percentage of the total square footage each painted. Who earned the most and who earned the least for this job?
Answers
Answer:
Elsa earned the most
Ben earned the least
Step-by-step explanation:
E = Elsa's speed
B = Ben's speed
C = Cal's speed
The combined speeds are:
E + B = 1/11
E + C = 1/9
B + C = 1/9.9
If we add up all three equations:
2B + 2C + 2E = 10/33
B + C + E = 5/33
If we subtract each of the first three equations from the total equation, we can find the individual speeds.
C = 5/33 − 1/11 = 2/33
B = 5/33 − 1/9 = 4/99
E = 5/33 − 1/9.9 = 5/99
Ben and Cal paint together for 1 hour. The fraction of the wall they paint is:
(1/9.9) × 1 = 10/99
Elsa, Ben, and Cal all paint together for the next 4.5 hours. The fraction of the wall they paint is:
(5/33) × 4.5 = 15/22
Ben and Elsa then finish the job. The amount of wall left is 1 − 10/99 − 15/22 = 43/198. So the time it takes is:
(43/198) / (1/11) = 43/18 hours
The fraction of the wall that Ben paints is:
(4/99) (1 + 4.5 + 43/18) = 284/891
The fraction of the wall that Cal paints is:
(2/33) (1 + 4.5) = 1/3 = 297/891
The fraction of the wall that Elsa paints is:
(5/99) (4.5 + 43/18) = 310/891
Answer:
Ben earned the most as 6 of 16.5 as a percentage = (6*100):16.5 =36.36%
We check with Elsa and she earned the least as (5*100):16.5 =30.31%
Cal earned the average as 5.5 of 16.5 as a percentage = (5.5*100):16.5 =33.33%
Step-by-step explanation:
E + B = 11hrs
E + C = 9hrs
B+C = 9.9 hrs
Lets say the house was 100ft sq
if E took 5.5 hrs
B took 5.5hrs we would have 11
C took 3.5 hrs we would have 9hrs for E+C
B took 5.5 hrs + 3.5hrs we are 0.9hrs short and see that B would need to take 0.9 more which means E works 0.9hrs less and shares 0.4 less with C having 0.5 less which gives B an extra 0.4 instead of 0.9
This equates to B: 5.9 , C: 3.9 , E: 5.1
We can change to B: 6 , C: 3.94 , E: 5.4
= E+B = 11.4 = 11
= E+C = 8.99 = 9
= B+C = 9.94 = 9.9
Percentages of fixed net pay when B: 6 , C: 3.94 , E: 5.4 = 6+ 3.94+ 5.4 = 100
Time when 15.34 hrs = 100% if working same rate changes to 16.5hrs to account for the hours given 8am-1.30pm 8am-1.30+ 9am-1.30+ = minimum 1hr more = 2pm
Cal worked 8 am till 1.30 pm = 5.5hrs = 1.66hr extra
Ben worked 8am till 2pm = 6 hrs = 0 hr extra together worked 11.5hrs
Elsa worked 9am till 2pm = 5 hrs = -0.4hr less
11.5+ 5 = 16.5 This equals 16.5hrs = 100%
Ben earned the most as 6 of 16.5 as a percentage = (6*100):16.5 =36.36%
Cal earned the average as 5.5 of 16.5 as a percentage = (5.5*100):16.5 =33.33%
We check with Elsa and she earned the least as (5*100):16.5 =30.31% is the same as 100-69.67%

I think it's 15.2cm and 19.2cm
Step-by-step explanation:
The ratio of corresponding sides of similar triangles are equal.
Answer: x = 17.2, so AB= 15.2 and AC= 19.2
Step-by-step explanation: Set up a ratio.
12:9.5 = (x+2)/(x-2)
Cross Multiply
12(x-2)=(9.5)(x+2)
12x-24=9.5x+19
2.5x = 43
x = 17.2
AB= 17.2 -2 = 15.2
AC= 17.2 +2 = 19.2

Travis wants to buy some CDs over the Internet. Each CD costs $8.01 and has a shipping cost of $9.95 per order. If Travis wants to spend no more than $50 for his CDs, which inequality shows the maximum number of CDs, p, that he can buy?
9.95p − 8.01p ≤ 50, so p ≤ 2
9.95p + 8.01p ≤ 50, so p ≤ 4
9.95 + 8.01p ≤ 50, so p ≤ 5
9.95 − 8.01p ≤ 50, so p ≤ 6
Answers
Answer:
9.95 + 8.01p ≤ 50, so p ≤ 5
Step-by-step explanation:
So to set up the equation you must first add 9.95+ because every order has a shipping fee of 9.95
Then you put in 8.01 is less than or equal to 50 because p representing a number of players is being multiplied by the unit cost 8.01. Trace is also wants the total to be under 50 dollars
Finally p is less than or equal to 5 because if you put the value 5 in for p in the equation, the equation is true.
The whole equation is 9.95 + 8.01p ≤ 50, so p ≤ 5

What is the scale factor of the model?/PLEASE HELP ME SOLVE ALL OF THESE PROBLEMS !!!!!!!!!!!!!!!!!!!!!!!!!
and please answer all of them or I will report ur answer
Answers
Answer:
108 centimeters
Step-by-step explanation:
Given that :
Scale model used for the Eiffel Tower :
2 centimeter represents 6 meters;
This means 2 centimeters on the model represents 6 meters of the Eiffel Tower.
To obtain the height of the model in centimeter :
Let the height of the model = h
h of model = actual height of tower
Actual Height of tower = 324 meters
Using cross multiplication :
2 = 6
h = 324
6 * h = 324 * 2
6h = 648
h = 648 / 6
h = 108
Hence, height of the model = 108 centimeters
Answer: 108 centimeters
Step-by-step explanation:
2 centimeters represents 6 meters;
This means 2 centimeters on the model represent 6 meters of the Eiffel Tower.
Let the height of the model = h
h of the model is = to the actual height of the tower
Actual Height of tower = 324 meters
2 = 6
h = 324
6 x h = 324 x 2
6h = 648
h = 648 divided by 6
h = 108

Answers
Answer:
D. George's speed in miles per minute.
Step-by-step explanation:
This answer is quite confusing because A. and D. are very similar but here is my reasoning.
The slope of the line is 1.
So B. and C. isn't right because they didn't travel 1 mile and they don't have 1 mile left to drive.
Now it is between A. and D. (1 minute per mile and 1 mile per minute)
When talking about speed the distance comes first (Ex. 20 miles per hour), so the best answer is D.
