<span>13.5 = lw
13.5/l = w
3l + 2w = C
C = 3l + 2*(13.5/l)
C = 3l + (27/l)
dC(l)/dl = 0
3 - (27/l^2) = 0
3*(l^2) - 27 = 0
(l^2) - 9 = 0
(l - 3)*(l + 3) = 0
l = 3
13.5 = 3w
l = 3000; w = 4500
Therefore, to minimize the cost of the fence, length should be 3000 ft while width should be 4500 ft.</span>
Answer:
The answer is J: 1/2
Step-by-step explanation:
The answer would be 1/2, or 50% because there are 4 tiles and 2 tiles are vowels. Hamda would have at least a 50% chance of picking it.
Answer:
The cost of 6 cans of soup = $7.8
Step-by-step explanation:
The cost of 10 cans of soup = $13
The number of cans needed for the soup = 6
Now, Cost of 1 can of soup =
= $13 / 10 =$1.3
⇒The cost of 1 can of soup is $1.3
Now, The cost of 6 cans of soup = 6 x Cost of 1 can
⇒ 6 x $1.3 = $7.8
Hence, the cost of 6 cans of soup = $7.8
Answer:
You'll have to give more information about the question or about what you need solved.
Step-by-step explanation:
1. 2x + 50 = 100
subtract 50 on both sides and then divide by 2.
x = 25
180 - 100 = 80
m
2. 7x - 4 = 87
add 4 on both sides and divide by 7.
x = 13
180 - 87 = 93
m
3. 5x - 2 = 38
add both sides by 2 and divide by 5.
x = 8
180 - 38 = 142
m
4. 14 + 6x = 134
subtract both sides by 14 and divide by 6.
x = 20
180 - 134 = 46
m
5. x = 53
m
6. x = 14
m
