Multiply 200 rolls by 70%
200 *0.70 = 140
The bowler should knock at least 6 pins down 140 rolls
Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
5 and 6 is 65 and 3 and 2 is 25 so I would say add 65 and 25
Answer:
Step-by-step explanation:
