2.25 = 225 / 100 ;
0.04 = 4 / 100 ;
But, 225 > 4 ; then, 225 / 100 > 4 / 100 ;
Bigger is 2.25 !
Answer:
- C = 0.97m
- $1164 for 1200 miles
- 845 miles for $820
Step-by-step explanation:
Given a car's cost of operation is $485 for 500 miles, you want an equation relating cost for m miles, and solutions to that equation for 1200 miles, and for a cost of $820.
<h3>Cost per mile</h3>
The cost per mile is found by dividing the cost by the associated number of miles:
$485/(500 mi) = $0.97 /mi
<h3>Equation</h3>
The equation for the cost will show the cost as the cost per mile multiplied by the number of miles:
C = 0.97m . . . . . where C is cost in dollars for m miles driven
<h3>1200 miles</h3>
The cost for driving $1200 miles will be ...
C = 0.97(1200) = $1164
The cost of driving 1200 miles is $1164.
<h3>$820</h3>
The number of miles that can be driven for a cost of $820 is ...
820 = 0.97m
m = 820/0.97 = 845.36
About 845 miles are driven for a cost of $820.
Answer:
A. The distance of a race.
Step-by-step explanation:
If a person wants to know the amount of time it would take to finish the race would involve the function of how long the race would have to be because the entry fee of the race and the people involved in the race don't have anything to do with the amount of time it takes to finish the race.
You say to yourself "Self ! This is easy, and I refuse to let it scare me !
I know that 20 dollars minus 2 dollars leaves 18 dollars.
And I know that 20 cows minus 2 cows leaves 18 cows.
And I know that 20 puppies minus 2 puppies leaves 18 puppies.
So it's obvious to me that 20 of anything minus 2 of the same thing
is always 18 of them.
It doesn't matter whether the things are hairbows, goldfish, cars,
CDs, books, or 'x', 'y', or 'z'.
So 20m minus 2m is definitely 18m."
Let us say, the numbers are "a" and "b"
their sum is -13
a + b = -13
their product is 40
a * b = 40
solve for "a",
what is "b"? well, b = 40/a :)
