We have two stacks of styrofoam cups. One stack has 6 cups, and its height is 15 cm. The other stack has 12 cups, and its height is 23 cm. How many cups are needed

37.5 cups

Step-by-step explanation:

Given data

First stack (n)= 6cups ,

height = 15cm

Second stack(n) = 12 cups

Height = 23cm.

Solution:

First we need to calculate for the average

= H1 - H2 / n1 - n2

= 15 - 23 / 6 - 12

= -8 / - 6

= 4/3.

Next we need to obtain the height of 50cm using our average gotten.

= 50 / 4/3

= 75/2

= 37.5

37.5 cups would be needed to get a height of 50cm.

50- 250 is correct i did that one too

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
