T = total bill = 20 + 8.90 = $28.90
O = original bill
O * 1.18 = T
O * 1.18 = 28.90
O = 28.90 / 1.18
O = $24.49
Answer:
area = 254.5 m²
Step-by-step explanation:
area = πr² = (3.14159)(9²) = 254.46 m²
The answer is D. 877 + 228 + 34 + 104
Corresponding sides in the triangles MOP and MNQ are
MO and MN,
OP and NQ,
PM and QM.
Ratios of the corresponding sides for similar triangles should be the same.
MQ/MP =MN/MO
MQ/(MQ+QP) = MN/(MN+NO)
5/(5+x) = 6/(6+18/5)
5*(6+18/5)=6(5+x)
30+18 = 30 +6x
18=6x
x=3 =QP
120 + 0.40m = 50 + 0.50m
120 - 50 = 0.50m - 0.40m
70 = 0.10m
70/0.10 = m
700 = m....they will be the same at 700 miles
