Answer:
Step-by-step explanation:
height of triangle=√(11²-8.6²)=√(11+8.6)(11-8.6)=√(19.6×2.4)
=√(4×4.9×4×0.6)=4√(4.9×0.6)=4√2.94
area of triangle=1/2 bh=1/2×2×8.6×4√2.94
=34.4×√2.94
≈58.984
Answer:
the x would equal to 11 ,so x=11
Answer:
B
Step-by-step explanation:
Answer:
12 pounds
Explanation:
If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.
Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.
So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.
Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.
