Answer:
Factor by which kinetic energy increase = 4 times
Step-by-step explanation:
Given,
- Mass of the car, v1 = 1500 kg
- initial speed of car = 35 miles/h
= 15.64 m/s
Initial kinetic energy of the car is given by,
= 183606.46 J
- Final velocity of car v2 = 70 miles/hour
= 31.29 m/s
So, final kinetic energy of car is given by
= 734425.84 J
Now, the ratio of final to initial kinetic energy can be given by,
Hence, the kinetic energy will increase by 4 times.
So, it depends. Imma give you two answers, all of which are the same at the end. They just have different ways to do it.
1. So, it's<span> $9 per hour, or $9 per 60 min </span>
<span>You can write a ratio: 9/60 = n/1 </span>
<span>In this case you have to divide 9 by 60 cause
60/60 = 1 </span>
<span>And n=0.15 </span>
<span>Answer: you earn 15 cents per min.
2.</span><span>$9 = 900 cents </span>
<span>900 cents divided by 60 minutes = 15 cents in a minute.
Hope this helps love!! :)</span>
It's completely correct to use the ' / ' sign for division.
Every fraction means division. It means
(the top number) divided by (the bottom number) .
These are easy to do on a calculator, and by now you should
also know how to do them with a pencil.
1). 5,320 / 61 = 87.213... (plus more decimal places)
2). 776 / 28 = 27.714... (plus more decimal places)
3). 1,624 / 23 = 70.608... (plus more decimal places)
Answer:
n = 10
Step-by-step explanation:
move all terms to the left:
-2-(-(n-8))=0
calculate terms in parentheses: -(-(n-8)), so:
-(n-8)
get rid of parentheses
-n+8
add all the numbers together, and all the variables
-1n+8
go back to the equation:
-(-1n+8)
get rid of parentheses
1n-8-2=0
add all the numbers together, and all the variables
n-10=0
move all terms containing n to the left, all other terms to the right
n=10
Answer:
x=162
Step-by-step explanation:
101 + 123 + 104 + 112 + 106 + 162 / 6 = 118
