Answer:
Total price = $112.70
Step-by-step explanation:
Total price of all three items without tax = 4 + 94 + 6.35
= $104.35
Total price of all three items with tax = (100% + tax) * Price
= (100% + 8%) * 104.35 = 108% * 104.35
= 1.08 * 104.35 = 112.698
≅ $112.70
(2) Explain how to use estimation to check whether your answer is reasonable:
We can use estimation to check if a result is reasonable by plugging in the answer in the original equation.
E.g. x + 4 = 10; x = 10 - 4
We get that x = 6
Plug in x = 6 in x + 4 = 10.
6 + 4 = 10. Indeed the answer was a reasonable one.
Answer:
V=282.74in^3
Step-by-step explanation:
Volume of cylinder
V= TTr^2h
Where
TT=3.14
r=3
h=10in
V=3.14*3^2*10= 282.743in^3
Answer:
3+18=21
Step-by-step explanation:
first see the second number
let us assume as x & y
3+ (3×6)= 21
3+18=21
The first one is D because you would divide for amount each day, and the second one is A because that has the correct expression of division.
