The square root of 141 =
This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.
If you want it simplified (like with a calculator) it would be:
(0,0) , (1,4) , ( 2,8) are the ordered pairs
They played 82 games.....they won 44.....so they lost (82 - 44) = 38
ratio of wins to loses...
they won 44
they lost 38
the ratio would be : 44/38 which reduces to 22/19 or 22:19 or 22 to 19
Option C:
x = 90°
Solution:
Given equation:
<u>To find the degree:</u>
Subtract 1 + cos²x from both sides.
Using the trigonometric identity:
Let sin x = u
Factor the quadratic equation.
u + 2 = 0, u – 1 = 0
u = –2, u = 1
That is sin x = –2, sin x = 1
sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.
sin x = 1
The value of sin is 1 for 90°.
x = 90°.
Option C is the correct answer.
Answer:
y = 22.5x
worked 28 hours
Step-by-step explanation:
First find out what they make in 1 hour (rather than 40)
you can do this by 900 / 40 which gives you 22.5
this means for every hour worked, they get $22.50
so you can make the equation of y = 22.5x
try finding the hours worked by division
630/ 22.5 = 28
plug 28 into your equation to check
y = 22.5 ( 28 )
y = $630
hope this helps
