7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?

Answers

Answers:

1)10.80/12 =0.90

0.90+0.75=1.65

2)252/7=36 units

3)cost price = $9.25*225

= $2081.25

Selling price = $15.75*225

= $3543.75

Profit = Selling price - cost price

Profit = $3543.75 - $2081.25

=$1462.50

5) FV = L*(1 + rt),

Where FV is the amount to repay; L is the borrowed amount (the loan amount) and "r" is the annual interest as decimal; t is the time.

In your case L = 2400 dollars; r = 8% = 0.08 (as decimal) and t = 0.5 of a year (6 months).

Therefore,

FV = 2400*(1 + 0.08*0.5) = 2496.

In 6 months, Della Rilley must repay $2496

Ans: 4 days

The number of kilograms that an object weighs varies directly as the number of pounds. If an object weighs 45 kilograms or about 100 pounds, about how many kilograms is an object that weighs 70 pounds?

Answers

Answer:

This is the specific answer: 31.7515

Answer: 31.5

Step-by-step explanation:

To solve this ratio problem, you need the common ratio. Divide the amount of pounds by the amount of kilograms.

Step 1: Divide 100 pounds by 45 kilograms

100 ÷ 45 = 2.2

This is the common ratio

Step 2: Divide 70 pounds by 2.2

70 ÷ 2.2 = 31.5

This is the amount of kilograms in a 70 pound object

how to graph x<-28 on a number line

Answers

Draw out a number line. Make sure -28 is on the number line, along with other optional values (such as 0 perhaps). At -28, plot an open circle or hole. This indicates this value is not part of the solution set. This is because there is no "or equal to" as part of the inequality sign. Then shade to the left to indicate values smaller than -28.

So in summary, you'll have an open hole at -28 and shading to the left.

Rapid Rental Car charges a $40 rental fee, $25 for gas, and $0.65 per mile driven. For the same car, Capital
Cars charges $55 for rental and gas and $0.75 per mile.
Part 1 out of 2
For how many miles is the rental cost at both companies the same?
The rental costs at both companies are the same at
miles.

Answers

Equation

40 + 15 + 0.25x = 45 + 0.35y

Solution

55 + 0.25x = 45 + 0.35y The only way you can do this is to assume that x and y are equal

subtract 45 from both sides

55 - 45 + 0.25x = 0.35x

10 + 0.25x = 0.35x Subtract 0.25x from both sides.

10 = 0.35x - 0.25x

10 = 0.1x Divide by 0.1

10/0.1 = x

x = 100 So if each car goes 100 miles, it should turn out to be the same no matter which company gets the rental.

Let's see if that is true.

Cost for the first company = 40 + 15 + 0.25x = 55 + 25 = 80 dollars.

Cost for the second company = 45 + 0.35x = 45 + 35 = 80 dollars.

Conclusion

Both rentals charge the same total amount when each car is driven 100 miles.

The charge is 80 dollars.
