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:
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
4) 654miles/55mph=11 hours, 53 minutes, 27 seconds ANS: ap.12 hours
time = distance/speed
6) 60*3=180mins
180/45=4
Ans: 4 days
7) This is a decrease of 8
a decrease of 28.57% rounded to two decimals

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?
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
(Is this right I don't know, I'm trusting my hands right now)
For each equation, what could you do first to each side of the equation so that there would be no fractions?
Select all the correct responses next to each equation.
[tex]\frac{3x+4}{8} = \frac{x+2}{3}[/tex]
o Multiply each side by 8
o Multiply each side by 30
o Multiply each side by 48
o Multiply each side by 24
o Multiply each side by 60
o Multiply each side by 12

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?
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

Find the sum of the roots of the quadratic x^2 + 7x - 13 = 0
Answer:
-7
Step-by-step explanation:
You use the quadratic formula of [tex]ax^{2} +bx+c = 0[/tex] to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))
[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2} \\\\x=-\frac{7}{2} - \frac{\sqrt{101}}{2}[/tex]
The sum of these two x values turns out to be:
[tex]x=-\frac{7}{2} + \frac{\sqrt{101}}{2}+( -\frac{7}{2} - \frac{\sqrt{101}}{2} )= -\frac{14}{2} = 7[/tex]
