A parking attendant charges a different rate for cars than for trucks. It costs $10.75 to park 3 cars and 2 trucks. It costs $12.25 to park 7 cars and 1 truck. How much does it cost to park a single car? A single truck?
Answers
Answer:
$1.25 to park a car and $3.50 to park a truck
Step-by-step explanation:
Set up a system where c is the number of cars parked and t is the number of trucks:
3c + 2t = 10.75
7c + t = 12.25
Solve by elimination by multiplying the bottom equation by -2 to eliminate t:
3c + 2t = 10.75
-14c - 2t = -24.5
Add them together and solve for c:
-11c = -13.75
c = 1.25
Then, plug in 1.25 as c in the equation to solve for t:
3c + 2t = 10.75
3(1.25) + 2t = 10.75
3.75 + 2t = 10.75
2t = 7
t = 3.5
So, it costs $1.25 to park a car and it costs $3.50 to park a truck

Jordan uses three lemons to make 1 pitcher of lemonade. He makes 4 pitchers. How many lemons does he use altogether? *What visual would you use to draw this story problem?
Answers
Answer:
The number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons
Step-by-step explanation:
The number of lemons the Jordan uses to make 1 pitcher of lemonade = three lemons
The number of pitcher lemonades Jordan makes = 4 pitcher of lemonades
The number of lemons Jordan uses altogether, is given by the following relation;
1 pitcher of lemonade = 3 lemons
4 pitcher of lemonades = 4 × 3 lemons = 12 lemons
Therefore, the number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons.

If PR = 25 and PQ = 12, then QR=
Answers
Answer:
QR= 13
Step-by-step explanation:
the points on the line in order from left to right are P, Q, R, which means that the distance from P to R is the length of the line. So PQ is only about half the line. To solve this question you would subtract 12 from 25:
25-12=13
hope that helps. can i have brainliest?
Answer:
It depends on whether P lies on QR or not.
If not, we can't find the exact answer for this question.
If P does, there are 2 cases:
Case 1: P is between Q and R
so QR = PQ + PR = 12 + 25 = 37
Case 2: Q is between P and R (because PQ < PR so there is no likelihood for R to lie betweem P and Q)
so QR = PR - PQ = 25 - 12 = 13

A species of fish was added to a lake. The population size Pt of this species can be modeled by the following function, where t is the number of years from the time the species was added to the lake. P(t) = 1000+(12e^−0.34t)where t is the number of years from the time the species was added to the lake.
Find the initial population size of the species and the population size after 9 years. Round your answers to the nearest whole number as necessary.
Answers
Answer:
1,012 ; 1,001
Step-by-step explanation:
Given the population function :
P(t) = 1000+(12e^−0.34t)
where t is the number of years from the time the species was added to the lake.
Initial population size of the species ; that is the population at year 0
At time, t = 0
P(0) = 1000+(12e^−0.34(0))
= 1000 + (12e^0)
= 1000 + 12(1)
= 1012
Initial population = 1,012
Population after 9 years :
P(9) = 1000+(12e^−0.34(9))
= 1000 + (12e^-3. 06)
= 1000 + (12×0.0468876)
= 1000 + ( 0.5626523)
= 1000.5626
= 1001 ( nearest whole number)
