Answer: 300% Increase

Step-by-step explanation: Lets write and solve a percent equation. First lets subtract 12 from 48 to get 36. 48 - 12 = 36

Now, write the equation. P = percent increase

36/12 x 100 = p

3 x 100 = p

300 = p

So, the percent increase is 300%

Calculate the distance between (0,3) and (3,10) to 1 decimal place

Artemon [7]

Alright, so the distance formula is sqrt((x1-x2)^2+(y1-y2)^2), and plugging that in, we get sqrt((0-3)^2+(3-10)^2)=sqrt((-3)^2+(-7)^2)=sqrt(9+49)=sqrt(58)=around 7.6

He should add exact since money is involved
he could also estimate since they are so close together, but he would be off only 2 cents

The combustion of one gallon of automobile fuel produces about 5 pounds of carbon (in CO₂). Two autos are making a trip of 600 m

rewona [7]

Answer:

Approximately 50 pounds less carbon (in CO₂) will be produced by the second auto on this trip.

Step-by-step explanation:

We have been given that the combustion of one gallon of automobile fuel produces about 5 pounds of carbon (in CO₂). Two autos are making a trip of 600 miles.

Let us find amount of fuel used by autos by dividing the total distance by their mileage.

$\text{Fuel used by 1st auto}=\frac{\text{ 600 miles}}{\frac{\text{ 20 miles}}{\text{gallon}}}$
