Ok so the Markup is how much money you will add on the price so it's 15% of $18 and you don't need to add it onto $18
The Retail Price is the entire price so the retail would be the Markup + Price.
15% of $18 is is $2.7 and $18 + $2.7 is $20.7

The average conversion energy from producers to primary consumers will be 10%
What will be the energy transfer from producers to primary consumers?As we know that energy can not be created nor be destroyed but it can only be transferred from one form to another.
So the primary consumers take energy as food and this energy is utilized in their metabolism and the remaining they transfer.
The average conversion energy from producers to primary consumers is only 10%.
This percentage actually holds true for all transfer of energy at any trophic level in the food chain.
Majority of the energy loss can be attributed to metabolic processes that give off heat and other forms of energy.

Answer:
-3.5625
Step-by-step explanation:
You may be able to round your answer, I am not sure.
Explanation:
3/8(0.4)-4.5
First, multiply 8 by 0.4 to get 3.2. Plug in that number to your new equation.
3/3.2-4.5
Now use order of operations (PEMDAS or GEMA) and divide 3 by 3.2.
0.9375-4.5
Subtract (Round that number if needed. If it says round your number, the answer will be different.)
Final Answer: -3.5625

aden’s teacher had 4 boxes of pens that each contained y pens. She took 6 pens out of one of the boxes and told her 17 students to divide the remaining pens equally among themselves. Which expression shows the number of pens each student got?
Answer:
Jaden’s teacher had 4 boxes of pens that each contained y pens.
Number of boxes of pen = 4
Number of pens per box = y
Total number of pens = 4 x y = 4y
She took 6 pens out of one of the boxes told her 17 students to divide the remaining pens equally among themselves.
Total number of pens left = 4y - 6
Number of students = 17

What is an equation of the line that passes through the points (-3, -2) and (2, -7)
Answer:
y=x-9
Step-by-step explanation:
There are 2 parts to finding the equation of a line: the slope and the y-intercept. In the equation y=mx+b, m is the slope and b is the y-intercept.
First, let's find the slope. 2-(-3)=5 and -7-(-2)=-5, so the slope is -5/5=-1.
Now we can plug in one of the given points to the equation to find the y intercept:
y=x+b
-7=2+b
b=-9
Now, we have the slope and the y intercept, so we can write the equation.
y=x-9

A. As the population of the beaver represents a certain law along with the year.
B. The point Q labels that 3.5 years after 1995 the amount of beaver has grown up to 475 approximately.
C. According to the question, the population is grown exponentially.
p(t) pass through point ( 1, 100), (2, 200), ( 3, 400), ( 4, 800)
therefore, 200 = 100 x 2 = 100 x 2 ^1 = 100 x 2^ 2-1
400 = 100 x 4 = 100 x 2 ^2 = 100 x 2^ 3-1
800 = 100 x 8 = 100 x 2 ^3 = 100 x 2^ 4-1
Answer = p (t) 100 . 2 ^ t-1
1), At Texas A&M University, tuition and fees for 4 years cost approximately $36,000. If a student could pay for these college expenses by the month, the student's monthly school bill would be about- A $650 B $700 C $750 D $900
Answer:
C- $750
Step-by-step explanation:
36,000 = 48b
Since the tuition fees for 4 years equals $36,000, you would first need to solve how many months equals 4 years (48). Divide the total sum of the tuition ($36,000) by the number of months the student would have to pay (48) in order to get $750/mo.
Write the equation of the line that goes through the points (-3,5) and (6,-1).
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
= 5 -(-1) / -3-6
= 6/-9
= -2/3
(y - y1) = m(x - x1)
y -(-1) = -2/3(x - 6)
y + 1 = -2/3x + 4
y = -2/3x + 3

We see : 4x - 5y = -20
We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y
Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20
And -4x + 5y is indeed 20, so the answer is infinitely many solutions.
Answer:
infinitely many solutions
Step-by-step explanation:
4x - 5y = - 20 → (1)
- 4x + 5y = 20 → (2)
add (1) and (2) term by term
0 + 0 = 0
0 = 0 ← true statement
this indicates the system has infinitely many solutions

One week into the course, a 27-year-old student is added to Mr. McKee's section roster. How does this change affect the standard deviation of the set of student ages?
The standard deviation will stay the same as it is not affected by a change in a single measurement,
What is a standard deviation?
A standard deviation is a measure of how dispersed the data when compared to the mean.
In this case, the standard deviation will stay the same as it is not affected by a change in a single measurement. Therefore, the change will not affect the standard deviation of the set of student ages.
