80
Step-by-step explanation:
8 is 10% of 80 and this was 60% (logical I guess)

To start off take the number of reams of crackers and divide by the total cost of the box: 12/9.89=1.21 and 4/4.29=0.93 to find out how much you pay per ream.
Then what I did was 12x0.93=11.16 (to find out how much you'd be paying with the local price)
Finally subtract 11.16-9.89= 1.27.
So in total you'd save $1.27.
Hope this helps
The window has a shape of a semi-circle (half of a circle).
We know the diameter d = 12 ft.
The area of a (complete) circle is given by the formula:
A = π × r²
The radius can be found by halving the diameter:
r = d ÷ 2
= 12 ÷ 2
= 6 ft
Therefore the area of the circle will be:
<span>A = π × r²
= 3.14 × 6</span>²
= <span>3.14 × 36
= 113.04 ft²
And the area of the semi-circle:
A = </span><span>113.04 </span>÷ 2
= 56.52 ft²
Hence, the area of the window will be 56.52 ft².
