Answer:
4 cm
Step-by-step explanation:
It's just what cubed is 64. The answer is 4 by the way since
4*4*4=16*4=64
54% of what is 216...
0.54x = 216
x = 216 / 0.54
x = 400....so there were a total of 400 people surveyed
The equation would be y=2/3x+4
So to finish the equation, you would need the slope and the y-intercept. The y-intercept is where the line hits the y-axis. So it hits the y-axis at (0,4), making the y-intercept 4.
Next find the slope. Do this by picking two points and plugging it into the equation
y2-y1/x2-x1
(0,4) (3,6)
6-4/3-0
2/3
So it would be y=2/3x+4
Cost of the compact disc player = 50 pounds
Percentage of VAT = 17 1/2%
= 35/2%
Then
Amount of VAT that needs to be given = (35/2)% * 50
= (35/200) * 50
= 1750/200
= 8.75
So the amount of VAT that has to be given is 8.75 pound
Amount that needs to be paid for the compact disc = (50 + 8.75) pound
= 58.75 pound.
So the total amount that needs to be paid for the compact
disc is 58.75 pounds
Since it can be expressed as fraction, it's a rational number.
