Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. after running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. he converts the average rate to feet per second as shown below: he concludes that she is not running fast enough to exceed her fastest time. 

Check: He used an incorrect time ratio converting hours to minutes

Check: He incorrectly concluded that she is not running fast enough

Do not check: His units do not cancel

Do not check: He used an incorrect distance ratio converting miles to feet

Do not check: He cannot determine her average rate in miles per hour after only 15 minutes

Step-by-step explanation:

You're welcome bud :)

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
