Answer:
100 miles
Step-by-step explanation:
Two plans are being offered for the renting of cars.
Plan A:
Cost per week = $200
Cost for each mile = $0.35
Plan B:
Cost per week = $180
Cost for each mile = $0.55
To find:
Number of miles for which the cost is same ?
Solution:
Let the number of miles driven so that the cost becomes the same = 
miles
First of all, let us find the cost for each plan as per miles.
Cost as per plan A = Cost per week + Cost for miles = $200 + $0.35
Cost as per plan B = Cost per week + Cost for miles = $180 + $0.55
Now, putting both the costs equal to find the value of :
Therefore, after <em>100 miles</em> the cost from each plan will be the same.
I’ll explains in the best way I can. Imagine the 3rd one but on the bottom square add one on the left and then one under that. So you would add a total of 2 squares. Hope this helps :)
Answer:
Negative, because negative plus positive = negative
Step-by-step explanation:
Multiples : these are what we get after multiplying a number by an integer (not a decimal or fraction)
Example : 6 * 1 = 6......6 * 2 = 12.....6 * 3 = 18......so 6,12, and 18 are multiples of 6.
factors : these are what we multiply by to get a number
Example : 1 * 6 = 6.....so 1 and 6 are factors of 6....2 * 3 = 6 ...so 2 and 3 are also factors of 6
==============================
problem 1 : Look at ur clues...each number is less then or equal to 12....this right here eliminates D because of the 15. The greatest common factor of the 2 numbers is 2....and this eliminates B because if it has a factor of 2, it has to be an even number. So that leaves us with :
A. 6 and 10
C. 10 and 12
last clue....they have a least common multiple of 60...this means that ur 2 numbers cant have any other common multiples until 60.
6 * 10......both are multiples of 60...however, they are also both multiples of 30...so 60 is not the least common multiple of 6 and 10, it is 30.
Therefore, ur answer is C. 10 and 12....with the LCM of 60, LCF of 2 and < or = to 12
===================
problem 2 : GCF (greatest common factor) of 42 and 84
factors of 42 : 1,2,3,6,7,14,21,42
factors of 84 : 1,2,3,4,6,7,12,14,21,28,42,84
therefore, the GCF of these 2 numbers is 42
The simple interest is 135$ per year, or 675$ total.
The compounded interest is 135$ the first year, 141.08$ the second year, 147.42$ the third year, 154.06$ the fourth year, and 160.99$ the fifth year, or 378.55$ total.
