Answer:
sorry man i dont know what that means
Step-by-step explanation:
Let us assume the original price of the coats before mark up = x
Cost of the coats after mark up = $3000
Percentage of mar up on the coats = 50%
Then
150x/100 = 3000
150x = 300000
x = 300000/150
= 2000 dollars
From the above deduction, it can be concluded that the actual cost of the coats were $2000. I hope the procedure is clear enough for you to understand.
19) The question is, for which n is n^(4t) equal to 16^(2t)
n^4t = n^(2*2t) = (n^2)^2t
so n^2 must be 16, so n=4
20) Fill in what you know:
<span>f(1) = -2f(0)+3 = -4+3 = -1
</span><span>f(2) = -2f(1)+3 = 2 + 3 = 5
</span>
21) The average speed is the total displacement divided by the total time. In this case the total time is easy, it is 5 seconds (from 5 to 10). The displacement will be d(10)-d(5).
d(10) = 0.8*100 = 80
d(5) = 0.8*25 = 20
So average speed is (80-20)/5 = 12
Answer:
Step-by-step explanation:
9/2 is the slope. Slope defines how steep is the straight line.
Slope = change in y ÷ change in x
In this model, 9 refers to the vertical distance between two points
and 2 refers to the horizontal distance between two points.
9/2 is a positive slope. It indicates that if 'x' increases, y also increase.
The answer is because 15-4 is 11
