Answer:
2% gain
Step-by-step explanation:
We assume the shopkeeper bought the appliances at the indicated prices, and that gain is computed on the basis of that cost price.
Since the base cost is the same for each appliance, the percentages can be added directly to find the percentage gain on 8000. However, the shopkeeper's total outlay was 16000, not 8000, so the final gain percentage is half of that total.
gain percent = (-4% + 8%)/2 = 2%
_____
If you want to see the actual numbers:
Loss on VCR = 4% × 8000 = 320.
Gain on TV = 8% × 8000 = 640.
Total gain on 16000 is -320 +640 = 320. As a percentage, that is ...
320/16000 × 100% = 2%
Answer:
Angle made by ramp with ground is ≈
Step-by-step explanation:
Diagram of given scenario is shown below.
Given that,
Horizontal Distance of Skateboard ramp is 
ft.
Height of Skateboard ramp is 
ft.
From figure,
It is forming a Right angle triangle 
.
In , 
and 
.
Clearly see that we need to find measure of angle 
.
Using Trigonometric ratio:
So, 
Then 
Therefore, Angle made by ramp with ground is ≈
Answer:
144.44
Step-by-step explanation:
C = 2 x π x r . C = 2 x 3.14 x 23 = 144.44

The answer to your question is: letter C
Step-by-step explanation:
Data
Find the Parabola's equation and express the equation as an inequality.
Vertex = (0, -5)
Equation
(x- h) ² = 4p(y - k)
x² = y + 5
y = x² - 5
But, we need the area upper the parabola, then
y ≥ x² - 5
Answer:
Step-by-step explanation:
17x – 7y = 19
17x – 19 = 7y
y = (17/7)x - 19/7
