Yaa is 10 years kwasi is 20 years and they share 60 mangoes and to a ratio of their ages find what each of them will get

Step-by-step explanation:

Yaa's age = 10 years

Kwasi's age = 20 years

They share the mangoes in the ratio of their ages

That's

10 : 20 = 1 : 2

Total number of mangoes = 60

Total parts = 1 + 2 = 3

= 2 × 20

Hope this helps you

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

- "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."
