You want to multiply 87.60 and 25.60 by 10. 87.60x10=876. 25.60x10=256.876-256=620. Then you will take 1/4 of 620 to get the answer 155 is what she paid for lessons.
Well I think it's b that's what I tjink
Answer:
A≈94.25in²
Step-by-step explanation:
Let T=Num of T-shirts 27
Let M=Total amount of money spent for 27 T-shirts.
Let X=Cost of 1 T-shirt
M(Total cost)/T(#of T-shirts) = X (Cost of one shirt)
angle QRP=180-(64+47)
=69°
Using sin rule,
p/sinP=q/sinQ.
7.6/sin64=q/sin47
q=6.2cm
Using the formula;
area=1/2p*qsinR
we have;
1/2×7.6×6.2×sin69°=21.995
answer= 22
