maks197457 [2]

Answer:

x = 5 , y = 15

Step-by-step explanation:

You can solve this using substitution.

Let the quantity of cheese wafers be denoted by x and the quantity of chocolate wafers denoted by y

2x + 1y = 25

x + y = 20

These two equations are the answer to part A, (remember to include the above prompt which says what x and y denote).

For part B I used substitution because it was more applicable to the question then addition or elimination.

ACTUAL WORK

Set 2x + 1y = 25 equal to x

x = 25 - y / 2

Replace x with y in the second equation

(25 - y / 2) + y = 20

And solve for y

y = 15

Since we know what y is we can replace y in the second equation and find what x is

x + 15 = 20

Solve for x

x = 5

Answer:  569.91\ ft^2

Step-by-step explanation:

From the given picture, the radius of the base of the cylinder = 5.5 ft.

The height of the cylinder = 5 ft.+6 ft.=11 ft.

We know that the surface area of a cylinder is given by :-

\text{Surface Area}=2\pi r (r+h)\\\\\Rightarrow\text{Surface Area}=2(3.14)(5.5)(5.5+11)\\\\\Rightarrow\text{Surface Area}=569.91\ ft^2

Hence, the surface area of the given cylinder = 569.91\ ft^2
