Answer:
2/18, 1/9
Step-by-step explanation:
5/18 + (-1/6)
-1/6=-3/18
5/18+(-3/18)=
2/18
Area of full circle= πr^2
Area of a quadrant= πr^2/4
=(3.5)^2π/4
=12.25π/4
=3.06πcm squared.
If you're asking for the model for the second problem (I didn't see any unsolved), here it is!
For the answer to the question above, n the 1st month, the accrued interest is ___ (1/12) * .0525 * 135400
subtract the interest from the payment to find the change in the principal for the 2nd month
find the 2nd month's interest and subtract from the payment to find the amount applied to principal. Then that's it!
(20*16 ft^2)(144 in^2/ft^2)(tiles/(10*10 in^2)
320ft^2(144in^2/ft^2)(tiles/100in^2)=460.8 tiles
However tiles are quantized integer units so 461 tiles will be needed to tile the kitchen.
