Answer:
B-10⁰
Step-by-step explanation:
5 x 10 is 50, 4 x 10 is 40, add those and you get 90⁰
Answer:
The 150 represents the distance Max ran.
Step-by-step explanation:
Step 1) In order to do this correctly you must make the fraction improper. 10/3 and 5/4
Step 2) To multiply two fractions the denominators (bottom numbers) must be the same. So you take 10/3 and times both the numerator (top number) and the denominator and times them by 4, giving you 40/12. Then you take 5/4 and times the numerator and denominator by 3, giving you 15/12.
Step 3) You then times the numerators together, 40 and 15, and the denominators together 12 and 12. Which give you 600/144 which simplifies into 25/6.
Step 4) Simplify the fraction by figuring out how many times 6 goes into 25 which is 4 and leaves you with 1/6 left over. Giving you your answer 4 1/6 miles.
Perimeter of the arc = 296/360 x
![\pi (42)](https://tex.z-dn.net/?f=%20%5Cpi%20%2842%29)
Perimeter of the arc = 108.5 cm
Total Perimeter = 108.5 + 21 + 21 =
150.5 cm
Answer:
It takes 26 2/3 gallons to make a 400 mile trip.
Step-by-step explanation:
This question is simply asking for the number of miles per gallon . In math, <em>per</em> means this is meant to be written as a fraction.
"If a trip of 270 miles required 18 gallons of gas" is actually saying "270 miles per 18 gallons." This can be written as a fraction like so: 270/18.
If we're looking for the amount of gas used for a 400 mile trip, we have the fraction: 400/g, g being the amount of gallons it took to make that trip.
Now we can set up the proportion: ![\frac{270}{18} =\frac{400}{g}](https://tex.z-dn.net/?f=%5Cfrac%7B270%7D%7B18%7D%20%3D%5Cfrac%7B400%7D%7Bg%7D)
Cross multiply and solve accordingly.
![\frac{270}{18} =\frac{400}{g}](https://tex.z-dn.net/?f=%5Cfrac%7B270%7D%7B18%7D%20%3D%5Cfrac%7B400%7D%7Bg%7D)
400
/g
So the answer is:
It takes 26 2/3 gallons to make a 400 mile trip.
