Answer:
20 waves
Step-by-step explanation:
Out of 50 waves, Mark will catch 20 waves. To find this, first, you have to put it into a ratio.
8 x
--- = -----
20 50
To solve this, you need to multiply 8 x 50, which is 400. Next you need to divide 400 by 20, which is 20 waves.
This means x = 20 waves.

Answer:
first method
<u>2</u><u>2</u>=<u>5</u>
7. x
we cross multiply to get
<u>2</u><u>2</u><u>x</u>= <u>5</u><u>×</u><u>7</u>
22. 22.
x= <u>3</u><u>5</u>
22
=1.59
second method
<u>2</u><u>2</u>=<u>5</u>
7. x
we multiply the denominators to get 7x
then we multiply each term by 7x
7x×<u>2</u><u>2</u> = <u>5</u>×7x
7. x
here the 7 and 7 will cancel out and the x and x will cancel out to get
<u>2</u><u>2</u><u>x</u>= <u>3</u><u>5</u>
22. 22
= 1.59
Answer:

Step-by-step explanation:
1st question explanation is 16+ 24 = 40
2nd question explanation is 19 x 8 x 9 = 1368
3rd question explanation is 8 x 2 1/4 x 2 1/2 = 45
DON'T COMPLAIN IF WRONG!
It is 6 units because you find the absolute value of the two different coordinates, in this case it is 4 and -2. Since they belong in different quadrants (one x or y value is positive and the other is negative) you add them. If they are both in the same quadrant, you subtract them.
