It will take them 4.24 hours together to paint the area together
Step-by-step explanation:
If Emily takes eight hours to paint the area then she will paint 1/8 of the house in one hour
Similarly, if Mike can paint the same area in 9 hours, then he will paint 1/9 of the same area
Let x be the number of hours in which they will together paint the area.
If x hours are taken by them to paint the area then 1/x of the area will be painted in one hour
So,
It will take them 4.24 hours together to paint the area together

Answer:
60 packets
Step-by-step explanation:
Given that :
Unit cost of 20 packets
$5.49 / 20 =$0.2745
Unit cost of 60 packets :
$10.97 / 60 = $0.1828333
Unit cost of 90 packets :
$18.95 / 90 = $0.2105555
The 60 packets has the least cost per unit, hence it is the best buy.
44x is the way the points are calculated. In order to find out the amount of questions there needs to be a constant, 10 which represents the number of wrong questions, and a variable, x which represents the number of correct questions. You have to know that if wrong questions were counted, he would have 440 points just for the 10 wrong questions. Next you have to add the amount of correct questions and their corresponding points. The numbers that you get should be put together with the wrong questions. The points for the wrong questions don't count but the questions do. When you find the number, (I don't know what it is so I will use x but you will have to find out what it is) you will add x, the number of correct questions to the 10 incorrect questions and then you will have 10+x for the questions. You will need to use 44x to find out the number of points and once you have done that, you use this equation to average the points over the total questions: 44x/10+x
Answer:
The price is now $44
Step-by-step explanation:
The original price is $55
The discount percent is20%
Calculate the savings: 20% of $55 = $11
Subtract the savings from the original price to get the sale price: $55 - $11 = $44
