Answer:
a. You can earn about $245
b. You will earn about $35 less if the lid is missing
Step-by-step explanation:
a. To solve this we first need to calculate the surface area of the drum, which has a cylinder shape, therefore it's surface area is given by:
surface area = 2*(pi*r² + pi*r*h)
r = d/2 = 4/2 = 2 ft
surface area = 2*(pi*2² + pi*2*5)
surface area = 2*(4*pi + 10*pi) = 2*14*pi = 28*pi ft²
surface area = 87.96 ft²
Since each square foot pays $2.79, then the total value of the drum is:
value = surface area * 2.79 = 87.96*2.79 = $245.42
b. If the lid of the drum is missing, then the surface area is given by:
area drum with no lid = surface area - lid area
area drum with no lid = 87.96 - pi*(2)² = 87.96 - 12.566 = 75.394 ft²
value = area drum with no lid * 2.79
value = 75.394 * 2.79 = 210.35
loss value = 245.42 - 210.35 = $35.07
Answer:
Coordinate of R is (-9, -2)
Step-by-step explanation:
Given
M (-6, 4)
S (-3, 10)
Distance between M and S are x = 3 y = 6
Since M is the midpoint between RS, such that distance between RM = MS
x = -6 - 3 = - 9
y = 4 - 6 = - 2
The first answer is x=63
the second one is x=10

Step-by-step explanation:
For this case we have that the variable "k" represents the floor area of Melanie's kitchen.
We have that the floor area of the room is 1.5 times the floor area of the kitchen, then, we propose the following function to find the floor area of the room:
