I took the test and got it right
Answer: B
Step-by-step explanation:
the cost is $8, and it goes for 40% off, so the discount is 8*40%=3.2;
then the sale price = 8-3.2 = 4.8.
Answer:
Step-by-step explanation:
With the expression 
, start by looking to see if you can take out any x-values. As you can see, both 
and 
have an x to the first power. You can factor that out, leaving you with the expression 
. Now you look for the largest numerical value that you can take out. Both 4 and 16 are divisible by 4, so you can factor out the number 4, leaving you with the expression .
They bowled for 3 hours and spent $7.
(I have no Idea how to make a graph on this website, so I can't help you there, sorry)
Let x = number of hours
Tucker: 2x+1
Blanca: x+4
2x+1 = x+4
x=3
For the graphs your lines should have equations like this:
y= 2x+1
y=x+4
The point of intersection of these lines should be at point (3,7)
Answer:
a = 
and b = 
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 =
So: a = and b =
