Overall 240 minutes Lin spend doing homework from monday to friday.
What is an expression?
Expression in mathematical is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Since Lin spent 80 minutes on monday doing homework and from tuesday to friday he is doing half the work before which means he will be doing in 40 mintues now for 4 days that is from tuesday to friday.
Now overall time in mintues he spend on homework will be sum of mintues spent on monday and mintues spent from tuesday to friday :
overall = 80 + 40x4
= 240 minutes
Therefore, overall 240 minutes Lin spend doing homework from monday to friday.

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.
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)

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?
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

If 80 is divided by the sum of 4 and a certain number , the result is 16 .find the number
Answer:
x = 60
Step-by-step explanation:
80/ 4+x = 16
(4 + x) * 80/ 4+x = 16 = 16 (4 + x)
80 = 16 + 4 + x
80 = 20 + x
60 = x or x = 60

If PR = 25 and PQ = 12, then QR=
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

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?
Answer:
The number of lemons Jordan uses to make the 4 pitcher of lemonade is 12 lemons
