Step-by-step explanation:

Let

Cost of popcorn = x

Cost of drink = y

3x + 5y = 24.5(1)

4x + 3y = 23.5(2)

From 1

3x + 5y = 24.5

3x = 24.5 - 5y

x = (24.5 - 5y)/3

Putting value of x in 2

4(24.5 - 5y)/3 + 3y = 23.5

98 - 20y/3 + 3y = 23.5

98 - 20y + 9y/3 = 23.5

98 - 11y = 3 × 23.5

98 - 11y = 70.5

-11y = 70.5 - 98.5

-11y = -28

y = 2.5

3x + 5(2.5) = 24.5

3x + 12.5 = 24.5

3x = 24.5 - 12.5

3x = 12

x = 12/3

x = 4

a cylinder with base are 169π ft^2 and a height twice the radius. what is the lateral area and surface area of the cylinder

Morgarella [4.7K]

$Area\ of\ base:A_B=169\pi\ ft^2\\\\A_B=\pi r^2\ \ \ (r-radius)\\\\\pi r^2=169\pi\ \ \ /:\pi\\\\r^2=169\\\\r=\sqrt{169}\\\\r=13\ (ft)\\\\H=2r\to H=2\cdot13=26\ (ft)$

$
lateral\ area:A_L=2\pi rH\\\\A_L=2\pi\cdot13\cdot26=676\pi\ (ft^2)\\\\Surface\ area:A_S=2A_B+A_L\\\\A_S=2\cdot169\pi+676\pi=338\pi+676\pi=1014\pi\ (ft^2)$

Billy-Bob has a piggy-bank filled with nickels and quarters totaling $11.90.

Lunna [17]

Answer:

x = 33

y = 41

Step-by-step explanation:

GIven

x: number of nickels

y: number of quarters

A nickel = $0.05

A quarter = $0.25

then we have the system of equations

0.05*x + 0.25*y = 11.90

x + y = 74

Which can be solved applying any of known methods. Then, the solution is

x = 33

y = 41

hope this was helpful.
