An ostrich can run at a rate of 50 miles in 60 minutes.At this rate,how long would it take an ostrich to run 15 miles?

1 answer:

3 0

If an ostrich can run 50 miles in one hour then he can run 12.5 miles in 15 minutes. 15 minutes is 1/4 of an hour. Multiply 50 by 0.25 = 15.

F(x) = -9x + 2 and g(x) = -9x + 6, find (f - g)(7)

Answer:

I think there is an error in the question because

(f-g) = -4

(f-g) (7) = NO SOLUTION

Step-by-step explanation:

$f(x) = -9x + 2 \\g(x) = -9x + 6\\(f - g)(7)\\(f - g) = -9x + 2 - (-9x+6)\\(f - g) = -9x +2 +9x-6\\(f - g) = -9x +9x+2-6\\(f - g) = -4$

at a shop on times square three''I love NY'' shirts sell every 10 minutes for $19.95 each.Every 45 minutes on Yankee's hat sells

Marizza181 [45]

I believe the answer 30,164.4

you multiply 19.95 by 3 and you get 59.85
then you figure out how many hours are from 9 am to 9 pm which was 12 then you multiply that by 6 then you take 59.85 and multiply that by 72 then you multiply that by 7
