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:
b) What is Jennifer's running speed?
Divide:
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:
B.
Step-by-step explanation:
The range is all real numbers
It will indefinitely go up and indefinitely go down
Answer:
32.66 units
Step-by-step explanation:
We are given that
Point A=(-2,-4) and point B=(1,20)
Differentiate w.r. t x
We know that length of curve
We have a=-2 and b=1
Using the formula
Length of curve=
Using substitution method
Substitute t=12x+14
Differentiate w.r t. x
Length of curve=
We know that
By using the formula
Length of curve=
Length of curve=
Length of curve=
Length of curve=
Length of curve=
Is it 0.092?
I got this by using the information from pH 4 which is 15 and doubling it to make 30 and taking away 5 (we get 5 from halving the the rate for reaction at pH6) to get 25.
0.071 x 2= 0.142
0.100/2 =0.05
0.142+0.05 =0.092
So, three and seven combine to make 10. Becoming good at mental math can be achieved by noticing things like this. Your mind should automatically see 43 and 17, know that 3 plus 7 equals 10. So there you have 50 plus 10 plus 27. Which is very simple to do. Your final answer will be 87.
