Answer: 6.56hours.
Step-by-step explanation:
Given;
Mario and julio can wash 7 cars in 2hours
While only mario can wash 5 cars in 3hours
Let m represent the rate at which mario work
j represent the rate at which julio work
t represent the rate at which mario and jolio combined work.
t = m + j
j = t -m .......1
t = 7 cars per 2hours = 7/2 = 3.5cars/hour
m = 5 cars per 3hours = 5/3 = 1.67cars/hour
From eqn 1
j = t -m = 3.5 - 1.67 = 1.83cars/hour
So, to determine the number of time it will take julio to detail 12 cars
Where = number of cars detailed
N = rate × time = j × time
time = N/j
time = 12/1.83
time = 6.56 hours
Therefore, it will take julio to detail 12 cars is 6.56 hours.
If you are looking for 185% as a fraction, you need to put your percentage over 100.
185% converted into a fraction is 185/100.
If you are looking for 1.85%, it is 1.85/100
I hope this helps!
To find weight you use the equation w=m*a. W is weight, m is mass, a is acceleration due to gravity. Since acceleration due to gravity is different on the moon than it is on earth that is the dependant variable. Since the persons mass does not change that is the independent variable
I guess it is 79 but you have to check because I am not sure
Answer: 16 boxes and 6 football cards in each box.
Step-by-step explanation:
Here total football cards rob has = 96
And, He filled 9 boxes with basketball cards.
Also, Rob filled 3 fewer plastic boxes with football cards than basketball cards.
Therefore, football cards in each boxes = 9 - 3 = 6
Thus, the number of boxes he can fill with football cards = 96/6 =16
