Answer 2
Answer: P = 1.48km = 1480m
P = 2l + 2w
l = 460
2l = 920
1480 - 920 = 560
560 = 2w
560 ÷ 2 = 280
280m = width or w

What are two inequalities to compare -17 and -22

Answers

The two inequalities are

-17 > -22

- 22 < -17

What is inequalities ?

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Comparing the two numbers, if plotted on a graph, we can see that -17 is much nearer to the point zero and -22 is farther from point zero. Therefore, we can say that -17 is greater than -22 or -22 is less than -17.

This can be represented with the help of two inequalities, greater than and less than.

first, -17 > -22   (greater than)

second, - 22 < -17 (less than)

Answer:

1/20

Step-by-step explanation:

There are 16 marbles, 4 of them blue.

The probability of getting a blue marble on the first draw is 4/16.

Now there are 15 marbles, 3 of them blue.

The probability of getting a blue marble on the second draw is 3/15.

These are independent events, so the total probability is found by multiplying the two probabilities together:  4/16 x 3/15  =  1/20
