A window in the shape of a parallelogram has the dimensions given. What is the area of this window? 20 ft² 24 ft² 28 ft² 40 ft² Parallelogram A B C D with side A D parallel to side B C and side A B is parallel to side D C. Point E is on side A B. Segment A E is 2 ft. Side D C is 5 ft. A dotted segment D E runs from point D to the opposite side A B and is perpendicular to side A B. Segment D E is 4 ft.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
