Answers

Answer:

3/2

Step-by-step explanation:

Look at 2 points that are easy to read.

For example, (-2, 0) and (2, 6).

slope = (difference in y)/(difference in x)

Subtract one y-coordinate from the other. Do the same with the x-coordinates in the same order.

slope = (0 - 6)/(-2 - 2)

slope = -6/(-4)

slope = 3/2

Figures ABCD and PQRS are parallelogram find x and y (lengths are in metres) Part i and ii.​

Answers

Step-by-step explanation:

For 1st question

In a parm ABCD

5x - 4 = 16 ( being opposite sides of parallelogram)

5x = 16 + 4

5x = 20

x = 20 / 5

x = 4

3y + 1 = 22 (being opposite sides of parallelogram)

3y = 22 -1

3y = 21

y = 21 / 3

y = 7

For second question

In parm PQRS

Diagonals bisect each other so

x + 4 = 12

x = 12 - 4

x = 8

x + y = 32

8 + y = 32

y = 32 - 8

y = 24

A tank has a volume of 1,500 liters of water.If you pour 500,000 milliliters out of it how much water will still be in it?

Answers

Answer:

Step-by-step explanation:

first convert the milliliters to liters!
