A trucks position relative to a cars position is -60 feet. The car and the truck move in the same direction , but the car moves 5 feet per second faster for 8 seconds. What operations could be used to find the trucks relative position after 8 seconds. EXplain
Answer:
The truck's relative position with respect to the car is: -100 feet
Step-by-step explanation:
If the truck is moving at a seed "V" then its position after 8 seconds is going to be:
XT = V* t = V * 8 = 8 V
The car, which is initially 60 feet ahead of the truck and starts moving at 5 m/s faster than the truck, would have a speed given by: V + 5
And its position (relative to the truck's) would be:
XC = 60 + (V + 5) * t = 60 + (V + 5) * 8 = 60 + 40 + 8 V = 100ft + 8 V
then the position of the truck relative to that of the car would be given by the difference:
XT - XC = 8 V - (100 +8 V) = 8 V - 8 V - 100ft = -100 feet

A cell phone plan has a monthly cost that is shown in the table below. What is the correct statement regarding the average rate of change
during the 40-minute time of talk? (1 point)
Answer:
Second from top...
The average rate of change is $0.07, meaning that for each minute of talk time, the monthly bill increases by $0.07.
Step-by-step explanation:
Pick any two points and calculate the slope which will represent the rate of change:
(Minutes, Cost)
(0, 9.95)
(10, 10.65)
Rate of change:
slope m = (y₂ - y₁) / (x₂ - x₁)
= (10.65 - 9.95) / (10 - 0)
= 0.7 / 10
= 0.07
y is cost
m is rate of change
x is minute(s) use
b is fixed monthly cost regardless if any minutes is used
y = mx + b
y = .07x + 9.95

A rectangular garden has side lengths of 12 feet and (x+10) feet. The garden has an area of 480 square feet. Write an equation and solve for x
Answer:
Step-by-step explanation:
12+x+10=480
22+x=480
x=458
2(12)+2(x+10)=480
24+2x+20=480
44+2x=480
2x=436
x=218
If a bike is going at 26 centimeters per second how many meters per minute is she traveling?
Answer:
15.6 meters in a minute
Step-by-step explanation:
Here's why:
1 centimeter= 0.01 meter
So, if you have 26 cm, that equals 0.26 meters.
Now, we know that there are 60 seconds in a minute.
So, we have to do 0.26 times 60 which equals 15.6 meters.
I hope this helps you! :)

Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a
trainer. For how many sessions is the cost of the two plans the same?
Answer: For 10 sessions, the cost of the two plans the same.
Step-by-step explanation:
Let x= Number of sessions.
Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Total charge for x sessions = 50+30x
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a trainer.
Total charge for x sessions = 250+10x
When both plan charges the same, then
[tex]50+30x=250+10x\\\\\Rightarrow\ 30x-10x=250-50\\\\\Rightarrow\ 20x=200\\\\\Rightarrow\ x=10[/tex]
i.e. For 10 sessions, the cost of the two plans the same.

2. An item used to sell for seventy-five cents a pound, and you see that it's been marked up to
eighty-one cents a pound. What is the percent increase?
Answer:
4%
Step-by-step explanation:
Answer:
It is not 4%. The answer is 8%
Step-by-step explanation:
First subtract .75 from .81 and you get the difference between the two prices .06 cents. Now use the formula % = (amount of increase)/(original amount) * 100.
Substitute and you get X = .06/.75 * 100
X = 6/.75 (.06 * 100 = 6)
X = 8
8%
