Answer:
128 lawn mowers were manufactured.
Step-by-step explanation:
Let's call z the number of manufactured lawn mowers
The general expenses are: $ 34 816
The costs per lawn mower are $388(z)
We know that:
Total cost (c) = Variable cost + fixed cost
So

The average cost of production Cp is equal to c/z
So:

We know that Cp = 660.
Finally:

64=2πr
642π=r
32π=r
r≈10.186
X=7.1cm

Answer:
0.75 could be a 25% discount. 1.06 could be a sales tax.
Step-by-step explanation:
If p is the original price, then 1.06p could be the amount after a 6% tax is include. Then multiplying by 0.75 could indicate a 25% discount (if you <u>don't</u> pay 25% = 0.25, then you <u>do</u> pay 75% = 0.75).
In case you're wondering about discounting <u>first</u> then charging tax, the result is the same because the multiplication can be done in either order.
0.75(1.06p) = 1.06(0.75p)
Ratio of rise can also mean the slope so let's find the slope given the two points.
slope formula;
m = y2 - y1/ x2 - x1 (3, 4), (-2, 0) (x1, y1), (x2, y2)
m = 0 - 4/ -2 - 3
m = -4/-5
m = 4/5
so your answer is B.
hope this helps, God bless!
