Answer:
D. 8 1/2 ÷ 5/6 = x
Step-by-step explanation:
let x be the number of smaller boards
Dividing the total amount of board by the length of each board gives the number of smaller boards.
The division statement is in the format:
Total ÷ number of groups = amount per group
OR
Total ÷ amount per group = number of groups
Each group is a small board. The amount per group is the amount of feet for each board.
8 1/2 ÷ 5/6 = x
The probability of losing per flip is 1/2. Multiply 1/2 by itself 6 times since the condition is asking for the probability for the person to lose 6 times in a row. 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/64. The answer is 1/64.
Answer:
20 * 19.52 = 390.40

First we need to find the total annual costs for both the plans.
In case of leasing:
Fixed monthly cost = $420
So, yearly cost = 420 x 12 = $5040
Cost per mile = $0.08
For x miles driven, the cost per year for leasing will be = 5040 + 0.08x
In case of purchasing:
Fixed yearly cost = $4600
Cost per mile = 0.10
For x miles driven, the cost per year for leasing will be = 4600 + 0.10x
We want to find for what number of miles will the cost of leasing will be no more expensive than the cost of purchasing.
So,
Cost of leasing ≤ Cost of purchasing
5040 + 0.08x ≤ 4600 + 0.10x
440 ≤ 0.02x
22000 ≤ x
Thus, if if the number of miles driven are equal to or less than 22,000 leasing will be no more expensive than purchasing.
