Answer:
1/4 × 16/3
Step-by-step explanation:
if 1 lap required 1/4 hour
the 16/3 require 1/4 × 16/3 hour ( cross multiplication)
Here is the solution of the given problem above:
Given: appliance A, B and C: 1 7/8 watts x 3 = 45/8 watts
appliance D : 4 3/4 watts
appliance E : 4 3/4 watts
?: total power used by these appliances
In order to know the total, we just have to add the number of watts.
So we add 45/8 watts plus 38/4 watts. The common denominator for these two fractions is 32. Therefore, the final answer would be 15 4/32 or 15 1/8 watts. The correct answer would be the last option. Hope this answer helps.
Answer:
The proportionality constant is 2/5
Step-by-step explanation:
Here, we want to get the proportionality constant
Let us view the two points as being points on a line
The constant of proportionality will be the slope of the line that connects the two points
Mathematically, we can use the formula for the slope of a line
We have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (20,8)
(x2,y2)= (25,10)
m = (10-8)/(25-20) = 2/5
