Answer:
8 days
Step-by-step explanation:
Let the number of days she rented bicycle be "b"
The total cost is fixed cost + variable cost.
Fixed cost = 55
Variables cost = 8.50 each day for b days, that is 8.50b
So, total cost is:
Total Cost = 55 + 8.50b
We know total cost is 123, so we can write:
123 = 55 + 8.50b
Now, we solve for b:
So, she rented the bicycle for 8 days
He has 29/36 of his copies left
convert 7/12 to 21/36 and convert 2/9 to 8/36 so you get like denominators, then add the two together and get 29/36
Answer:
40 gallons of water and 140 gallons premium antifreeze
Step-by-step explanation:
Let p represent the number of gallons of premium antifreeze in the mix. Then 180-p is the number gallons of water. The amount of pure antifreeze in the mix is then ...
0.90p + 0·(180 -p) = 0.70·180
p = 0.70·180/0.90 = 140 . . . . divide by the coefficient of p
180-p = 40 . . . . . find the water content
40 gallons of water and 140 gallons of premium antifreeze are in the mix.
Answer:
The views on first day is 100
on the second day is 200
so the views on second day is double than the first day.
similarly, the views on thirds day are double the views the second day.
This pattern continues....
