Answer:
5 miles per hour
Step-by-step explanation:
Let the speed of Kelly is 
miles per hour and speed of Raul is v₂ miles per hour.
Since, speed = 
Kelly took 135 minutes to cover 90 miles from New York to Philadelphia.
∵ 1 minute = 
hours
∴ 135 minutes = 
= 
hours
v₁ = 
= 
= 40 miles per hour
Raul took 153 minutes to cover the same distance as Kelly,
∵ 1 minute = hours
∴ 153 minutes = 
= 
hours
v₂ = 
= 35.29
≈ 35.3 miles per hours
v₁ - v₂ = 40 - 35.3
= 4.7
≈ 5.0 miles per hours
Therefore, Kelly is 5 miles per hours faster than Raul.
Answer:
In this problem it gives you the equation you need to solve it.
Y=10x+190
The question asks for the number of calories if the snack has 35 grams of fat. The grams of fat is the independent variable so it is going to be x. So just substitute the x in the equation with 35.
Y=10×35+190
Y=350+190
Y= 540
So for a snack that has 35 grams of fat, it would have 540 calories.

Answer:

Step-by-step explanation:
First find the rate of growth using the formula of
A=p e^rt
A 7200
P 6000
E constant
R rate of growth?
T time 6 hours
We need to solve for r
R=[log (A/p)÷log (e)]÷t
R=(log(7,200÷6,000)÷log(e))÷6
R=0.03 rate of growth
Now predict how many bacteria will be present after 17 hours using the same formula
A=p e^rt
A ?
P 6000
R 0.03
E constant
T 17 hours
A=6,000×e^(0.03×17)
A=9,991.7 round your answer to get
A=9992
