The value of A becomes less than the value of BR
Answer:
a) 11mph
b) 6mph
c) 25 miles
Step-by-step explanation:
She can run 12 miles in 2 hours.
She can bike 33 miles in 3 hours.
a) What is Jennifer's biking speed?
Divide:
![\frac{33mi}{3h}=11mph](https://tex.z-dn.net/?f=%5Cfrac%7B33mi%7D%7B3h%7D%3D11mph)
b) What is Jennifer's running speed?
Divide:
![\frac{12mi}{2h}=6mph](https://tex.z-dn.net/?f=%5Cfrac%7B12mi%7D%7B2h%7D%3D6mph)
c) Jennifer biked for 2 hours and then ran for 30 minutes. What distance did she cover?
She bikes 11 miles per hour.
2 hours would be = 11mi * 2 = 22miles
She runs 6 miles per hour.
30 minutes or 1/2 hour would be = 6mi * 1/2 = 3 miles
Add these distances.
22+3=25 miles
Answer:
Yes
Step-by-step explanation:
A right triangle's formula, according to Pythagorean's Theorem, is a² + b² = c². a and b are the two legs, and c is the hypotenuse. To solve, we must substitute the variables with the given measurements.
9² + 12² = 15²
Let's now solve:
81 + 144 = 225
225 = 225
The formula works out in the end, so it is a right triangle!
#1 Apple's: $7.56. (3 4/5 $1.99 # 19/5 x 1.99 = $7.56)
#2 Pears: $1.68 (3/4 $2.25. 3/4 x 2.25 = $1.68)
#3 Bananas: $6.42. (3 2/3. 11/3 x $ 1.75 = $6.42)
+ _____
$15.66
#4. 20.00
- 15.66
