Step-by-step explanation:
The first four common multiples of 5 are...
5, 10, 15, 20, 25, 30, 30, 40, 45, 50
The first four common multiples of 8 are...
8, 16, 24, 32, 40, 48, 56, 64, 72, 80
Answer: 5, 10, 15, 20, 25
8, 16, 24, 32
Answer:
Yes
The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).
The number of hours worked is and the money earned is .
Let us divide the values of by
The fuction which defines the above ordered pairs is
It can be seen that the amount of money earned is 12 times the number of hours worked.
So, per hour Jerry earns 12 dollars.
Hence, the ordered pairs are relation.
If is
x > 2 or x < 7 ⇒ x is any real number
x > 2 and x < 7 ⇒ 2 < x < 7
A set of all numbers that are greater than 2 and less than 7.
Look at the picture.
40
The formula for the perimeter of a rectangle is P = 2l + 2w. Since the length is 8 times the width, l = 8w. You can plug this into the equation.
<em>P = 2(8w) + 2w</em>
<em>P = 16w + 2w</em>
P = 18w
Now, plug in the given value for perimeter, and solve for w.
<em>90 = 18w</em>
<em>(90)/18 = (18w)/18</em>
5 = w
Since the width is equal to 5, you can now solve for l.
<em>l = 8w</em>
<em>l = 8(5)</em>
l = 40
The length of the diagonal is equal to 40.
