Answer:
The equation is 
Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases
So equation will be

Hence, equation representing the proportional relationship will be 
Answer:
The absolute error = 2 centimeters.
The desirable length = 45 cm
The minimum length = 43 cm.
The maximum length = 47 cm.
Step-by-step explanation:
Katie has been given a project to make a model car that is 45 centimeters long. The teacher has told her that variations in the length of up to 2 centimeters are acceptable.
Therefore, the absolute error = 2 centimeters.
The desirable length = 45 cm
The minimum length = (45 - 2) = 43 cm.
The maximum length = (45 + 2) = 47 cm. (Answer)
The answers are: -5.3, -6.5
Answer:
Step-by-step explanation:

The length of a rectangle is decreased by 25% and the width has increased by 40% calculate the percentage change in the area of the rectangle
to. find.
area of the rectangle
given
decreased. 25•/•
increased.40•/•
solusion
Length = L
Breadth = B
Original area = L x B
New area = A = L x (1 - 25%) x B x (1 + 40%)
A = L x B x 0.75 x 1.40 = L x B x 1.05
Therefore the area of the rectangle has increased by 5%.

Answer:
19
Step-by-step explanation:
Number of crackers that can be fit into the box = volume of the box / volume of crackers
Volume = length x width x height
volume of the box = 8 cm x 2.4 cm x 60 cm = 1152 cm^3
Volume of the crackers = 3cm x 4 cm x 5cm = 60cm^3
1152/60 = 19.2
Rounding 19.2 to the nearest whole number gives 19
