kwesi is putting on sunscreen. he uses 3 ml to cover 45 cm squared of his skin. he wants to know

how many milliliters of sunscreen (g) he needs to cover 240 cm squared of his skin. he assumes the relationship between milliliters of sunscreen and area is proportional.

how many milliliters of sunscreen does kwesi need to cover 240 cm squared of his skin?

16

Step-by-step explanation:

He assumed that relationship between milliliters of sunscreen and area is proportional.

Volume of sun screen used to cover

Volume of sunscreen require to cover  of skin will be=

16 milliliters of sunscreen (g) he needs to cover 240 cm squared of his skin.

- "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."

the answer is 13/48
