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
A ratio is a comparison of two quantities by division. Ratios describe a part-to-part comparison or a part-to-whole comparison. Ratios are written three ways: as a fraction, with a colon, and with the word “to.” The ratio for quantity a to quantity b is : a to b, a over b, and a:b
Answer:
2/3*22/7*r^3=231.6
2/3*22/7=2.0952
2.0952*r^3=231.6
r^3=231.6/2.0952
r^3=
Step-by-step explanation:
2/3*22/7*r^3=231.6

Answer:
0.50
Step-by-step explanation:
X ___ - 5 ___ 3 __ - 2 __ 0 __ 12 __ 3
P(x) __0.17_0.13_0.33 _0.16 _0.11 _0.10
P(x <0) = p(x = - 2) + p(x = - 5)
P(x < 0) = 0.33 + 0.17
P(x < 0) = 0.50
It will be x, if y depends on x
Because tent is dependent and the is independent
