A pile of sand has the weight 90kg. The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:
7 .work out the weight of sand in each bag

15kg:22.5kg:52.5kg

Step-by-step explanation:

 pile of sand has the weight 90kg. The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:

7 .work out the weight of sand in each bag

Ratio = 2:3:7 = small: medium :large

Total = 2+3+7 = 12

Total weight = 90kg

Weight of small bag = 2/12 × 90

= 90 ÷ 6

= 15kg

Weight of medium bag = 3/12  × 90

= 90÷ 4

= 22.5kg

Weight of large bag = 7/12 × 90

= 7 × 7.5

=52.5kg

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
