Answer:
Actual price of the TV=£880
1st price reduction of £80.50=£880-£80.50=£799.5
2nd price reduction=£799.5-£102.90=£696.6
Final sales price=£696.6
Answer:
I am really good at doing stuff like that
Answer:
-9x - y
Step-by-step explanation:
Combine like terms. That is, combine all the x terms and then, separately, combine all the y terms.
2x - 10y + 9y - 11x = -9x - y (answer)
First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.
