IrinaVladis [17]
Out of your $67 for the day, $40 of it goes to the rental before you even drive it out of the lot.  That leaves you $27 a day for mileage.

$27 / $0.18 per mile = <u>150 miles</u> per day, tops.

Suppose a bank charges a base rate of $5 plus $0.10 per check for your checking account. You can switch to a different account t
wolverine [178]

Answer:

10 number of checks.

Cost = $6

Step-by-step explanation:

Given that:

Fixed Charges of first bank = $5

Charges of first bank per check = $0.10

Fixed Charges of second bank = $4

Charges of second bank per check = $0.20

To find:

Number of checks such that the charges for the banks become the same?

Solution:

Let the number of checks = x

Cost for the first bank for x checks = $5 + $0.10x

Cost for the second bank for x checks = $4 + $0.20x

As per question statement, both the costs are the same.

Comparing the values:

5 + 0.10x = 4 + 0.20x\\\Rightarrow 0.10x = 1\\\Rightarrow x = 10

So, for 10 number of checks the cost will be same.

The cost = 4 + 0.20 \times 10 = <em>$6</em>

The length and width of a rectangle are in a 3:5 ratio. The perimeter of the rectangle is 64. What are the length and width?
Sveta_85 [38]

Answer:

L = 12

W = 20

Step-by-step explanation:

The perimeter of the rectangle is 64.

2L + 2W = 64

The length and width of a rectangle are in a 3:5 ratio.

3 + 5 = 8

64/8 = 8

2L = 8 * 3 = 24

L = 24/2 = 12

2W = 8 * 5 = 40

W = 40/2 = 20

7 − 9x − (x + 12) less than or equal to 25?
Nonamiya [84]

Answer:

x  ≥-3

Step-by-step explanation:

7 − 9x − (x + 12) less than or equal to 25

7 − 9x − (x + 12) ≤ 25

Distribute the minus sign

7 − 9x − x - 12 ≤ 25

Combine like terms

− 10x −5 ≤ 25

Add 5 to each side

− 10x −5+5 ≤ 25+5

− 10x ≤ 30

Divide by -10. Remember that this flips the inequality

− 10x/-10 ≥30/-10

x  ≥-3
