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

A jar contains only pennies, nickels, dimes, and quarters. There are 29 pennies, 13 dimes, and 21 quarters. The rest of the coins are nickels. There are 91 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
Answers
Answer:
First Question: 63 coins are not nickels.
Second Question: 63+n=91
Step-by-step explanation:
For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.
For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.
Hope that this helps! Good luck with what you're working on!
Answer:
63 coins are not nickels.
Equation to find n:
91 - 63
Or
91 - n

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.

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

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
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.
Hope this helped! :)
