Answer:
Step-by-step explanation:
I think the answer is 34
E=number of eight cent stamps
t=number of ten cent stamps bought
w=number of 2 cent stamps bought
number of eight=number of ten
e=t
as many 2 cent as the other 2 combined
e+t=w or
2e=w=2t
total she bouthgt 4.40
4.40=440 cents
8e+10t+2w=440
solve for t or e, I solve for t
8t+10t+2(2t)=440
18t+4t=440
22t=440
divide 22
t=20
t=e
20=e
w=2e
w=2(20)
w=40
answer is
20 eight cent
20 ten cent
40 two cent

Answer:
217.04 cm²
Step-by-step explanation:
We should first calculate the area of the rectangle:
A= 14*21 =294cm²
then we should substract the area of the half-cercle :
A'= (7²*π)/2=76.96 cm²
then the area of the shaded area is :
A"= 294-76.96= 217.04 cm²
