Victor wants to buy fertilizer for his yard. The yard measures 35 feet by 55 feet. The directions on the bag of fertilizer say that one bag will cover 1,240 sq ft. How many bags of fertilizer should Victor buy to be sure that he covers the entire yard?

2 bags

Step-by-step explanation:

area of the yard= 35*55= 1925 ft²

1 bag covers 1240 ft²,

required number:

1925/1240= 1.55 ≈ 2 bags

so 2 bags needed to cover the area of the yard fully

- "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."
