Miguel rode his bike 20 miles in 2.5 hours
(1)Starting information is , In 2,5 hours Miguel traveled 20 miles
(2)Now we complete the table
In 2,5 hours distance traveled = 20 miles
So in 1 hour distance traveled =
Time 0 0.5 1 1.5 2 2.5
Distance 0 4 8 12 16 20
(3) The graph is attached below
(4) Equation y = kx
y is the distance
x is the time
Distance = k (time)
We know speed is 8 miles per hour
So k is 8
y = 8k is the final equation
(5) k is the constant of proportionality
the value of k= 8
so 8 is the constant of proportionality.
Answer:
The power dissipated is 45W.
Step-by-step explanation:
The power varies jointly with resistance , and the square of current :
,
where is the constant of proportionality.
Now we are told that when and , :
solving for we get
,
which gives
With the value of in hand, we find the power dissipated when and
Thus, the power dissipated is 45W.
If 15 inches of wire costs 45 cents, that means each inch of wire costs 3 cents. So 12 inches of wire will cost 36 cents.
Answer:
Slope, m = 1.5
y-intercept, c = -4.3
Step-by-step explanation:
We are given the following equation in the question:
where F is foot length in millimeters and h is height in centimeters.
Comparing equation to a general linear equation:
where m is the slope and c is the y - intercept.
Slope, m = 1.5
y-intercept, c = -4.3
Interpretation of slope:
Slope tells us about the rate change. So, when the there is a unit increase in height the foot length changes by 4.3 foot.
Interpretation of y-intercept:
y-intercept is the value of F when height,h is zero that is
Answer:
If there are 16 pieces of fruit and 8 of them are oranges then 16 - 8 = 8. This proves that 8 is half of 16 so the percentage of oranges in the bowl is 50%
I hope this helps (:
