Answer:

40 cm³

Step-by-step explanation:

The information we have about the volume of Prism Y is only that it is 10 cm³ greater than the volume of Prism X. So, we have to first find the volume of Prism X.

The volume of a rectangular prism is found by multiplying the length, width, and height of the figure. X has dimensions of 2 × 5 × 3, so we will multiply these together.

2 · 5 · 3 = 30

The volume of prism X is 30cm³.

Prism Y is 10 cm³ greater than this.

30 + 10 = 40

Prism Y has a volume of 40 cm³.

Good luck :)

BIG JIM/LITTLE JIM PROBLEM When Big Jim stands on a bench that is 15 inches high, the top of his head is 53 inches above the top of Little Jim’s head. Big Jim’s height is twice that of Little Jim’s height. How tall is Big Jim? How tall is Little Jim?

Answers

Answer:

Let J = height of Little Jim. Then Big Jim's height is 2J.

when big jim stands on a bench that is 15 inches high, the top of his head is 53 inches above the top of little jims head.

The above given sentence means 15+ 2J= J+53.

15+2J = J+53

2J-J = 53-15

J = 38 inches

There are 25 dark chocolates in the bag and each is equally likely to be chosen.
Work out how many milk chocolates there must be.

Answers

Answer:

There are 300 milk chocolates in the bag.

Step-by-step explanation:

Since there is a bag with only milk and dark chocolates, and the probability of randomly choosing a dark chocolate is 1/12, if there are 25 dark chocolates in the bag and each is equally likely to be chosen, to determine how many milk chocolates there must be the following calculation must be performed:

1 = 25

12 = X

12 x 25/1 = X

300/1 = X

300 = X

Therefore, there are 300 milk chocolates in the bag.

You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of increase in the tree's height? 3643×100 43−3643 43−3636×100 43−3643×100

Answers

Answer:

19.4%

Step-by-step explanation:

Given data

Initial height=36in

Final height= 43in

% increase= Final-initial/initial*100

Substitute

% increase= 43-36/36*100

%increase= 7/36*100

%increase= 0.194*100

%increase= 19.4%

Hence the increase is 19.4%
