Suppose x books are produced by both methods.
Total cost for method 1 = 60346 + 10.5x
Total cost for method 2 = 18682 + 21x
Cost of method 1 = Cost of method 2
60346 + 10.5x = 18682 + 21x
60346 - 18682 = 21x - 10.5x
41664 = 10.5x
x = 41664/10.5
x = 3968
For 3968 books produced the cost by both methods will be the same.
Step-by-step explanation:
S = ∫ 2π y ds
ds = √(1 + (dx/dy)²) dy
ds = √(1 + (8y)²) dy
ds = √(1 + 64y²) dy
S = ∫₁² 2π y √(1 + 64y²) dy
S = π/64 ∫₁² 128y √(1 + 64y²) dy
S = π/64 [⅔ (1 + 64y²)^(³/₂)] |₁²
S = π/96 (1 + 64y²)^(³/₂) |₁²
S = π/96 (1 + 256)^(³/₂) − π/96 (1 + 64)^(³/₂)
S = π/96 (257√257) − π/96 (65√65)
S = π/96 (257√257 − 65√65)
4 is a regular rhombus I think don't quote me on that. I am pretty sure though
By rounding to the nearest liter, the question is asking us to round to the nearest whole number (get rid of any numbers after the decimal point). This means that we want the last number of our answer to be the number just to the left of the decimal point, which is a 3.
To determine if we should leave the number or round it up, we look to the number to the right of the 3 which is a 4. Because 4 is less than 5, we do not round up. Therefore, the answer would be 103 liters.
I hope this helps.
Answer:
95 12 18
100 100 10
Step-by-step explanation:
insted of the decimal put one and the numbers after the decimal will become 0 in the denominator. for example 1.5, the fraction will be : 15/100
