Answer:
The percentage of the markup is 82%
Step-by-step explanation:
In this question, we are asked to calculate the percentage of mark up. This is simply calculating the percentage of the profit margin.
firstly to be able to calculate this percentage, we need to know the value of the profit margin itself.
mathematically, the profit margin is selling price - cost price
From the question, the selling price is $1 while the cost price is 55 cents
The profit margin is thus $1 - 55 cents = 45 cents
We now proceed to calculate the percentage profit
mathematically, that is profit/cost price * 100%
That would be 45 cents/55 cents * 100 = 9/11 * 100% = 81.8 approximately 82%
The formula becomes w = (200P - 20)/3.
Given: Formula
P = (3w + 20)/200
Now, we will convert this in the form of P.
⇒ P = (3w + 20)/200
multiply both sides by 200, we get:
⇒ 200 P = 3w + 20
⇒ 200P - 20 = 3w
⇒ w = (200P - 20)/3
Therefore, the formula after making w as the subject becomes:
w = (200P - 20)/3

Answer:
Step-by-step explanation:
I assume the correct formula is
P = (3w + 20)/200
Solve for w.
200P = 3w + 20
200P - 20 = 3w
(200P - 20)/3 = w
y=3cos pi x
y=2 sin 3x
y=-4 sin 2x
Answer:
Option 2. y = 3 cos πx is the answer.
Step-by-step explanation:
If the function is in the standard form of y = acos(bx+c) or y = asin(bx+c)
Then period of the given function will be = 2π/b
1) For y = cos(x - π/2)
Therefore period of the function will be = 2π/1 = 2π
2) For y = 3cos πx
Period = 2π/π = 2
Correct option.
3) y = 2 sin 3x
Period of the function = 2π/3
4). y = -4sin 2x
Period of the function = 2π/2 = π
So option 2 is the answer.
