Answer:
per one foot of aluminum foil it costs .62 cents
Step-by-step explanation:
there are 3 ft in a yard
so 3 x 3 is 9 which is the total amount of feat
then divide 5.58 by 9
5.58 /9 = .62
this means that per one foot of aluminum foil it costs .62 cents
Answer:
The surface area of the object would be 0 or zero because there is not an object.

First step: name the sides according to geometry standards, namely, the sides are named the same lowercase letter as the opposing angle. A revised diagram is shown.
Second step: we need to know the relationships of the trigonometric functions.
cosine(A)=cos(63) = adjacent / hypotenuse = AC/AB .................(1)
sine(A)=sin(63) = opposite / hypotenuse = CB/AB .......................(2)
We're given AB=7, so
using (1)
AC/AB=cos(63)
AC=ABcos(63)=7 cos(63) = 7*0.45399 = 3.17993 = 3.180 (to three dec. figures)
Using (2)
BC/AB=sin(63)
BC=ABsin(63) = 7 sin(63) = 7*0.89101 = 6.237 (to three dec. figures).
