5/12 is not a whole number, however, their is a decimal for it.
5/12 = 0.416
Answer: 68.75
Step-by-step explanation: I did the math myself so it may not be correct, but it's at least very close.
(3) y= 5x+ 13
you have to do the rise (ryse - with a y because it is the y value) over the run to get your slope and then subtract your slope from 18 to get 13.
Answer:
The answer to your question is Brand B
Step-by-step explanation:
Data
Brand A amount of 20 pencils cost $6
Brand B amount of 40 pencils cost $8.5
Process
1.- Calculate the unit price of each brand of pencils dividing the cost by the number of pencils
Brand A 6/20 = $0.3
Brand B 8.5/40 = $0.21
2.- Conclusion
Brand B is a better deal because you buy more pencils for a lower price.
Answer:
1 m/s
Step-by-step explanation:
the area of the triangle = A = ¹/₂ab
where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²
now we find the derivative of both sides:
dA/dt = ¹/₂ ⋅ dx²/dt
dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt
dA/dt = x ⋅ dx/dt = x ⋅ velocity
we are told that x = 5 m, and dA/dt = 5 m²/s
velocity = dA/dt / x
velocity = 5 m²/s / 5 m = 1 m/s
