Answer:
14.14
Step-by-step explanation:
You can find the value of x using the trig ratio Sine = opposite/hypotenuse.
The sin 45 = 10/x. Solve for x.
x= 10/ sin45
x = 10/0.707
x = 14.14
The value is 60, if 15 is 25% of the value
The room is a square, meaning all four sides are 20ft long.
Because we know all the side lengths, we can find the perimeter of the square by adding the side lengths together.
(20 + 20 + 20 + 20) = 80
Now that we know the perimeter, we have to match this number to the feet of crepe paper.
We can find this by dividing the total length needed by the length a single roll provides.
80 / 8 = 10
Therefore, we know that Katie will have to buy a minimum of 10 rolls if she wants to cover the entire perimeter of the room.
Hope this helps! :)
Answer:
B
Step-by-step explanation:
First, find the y-intercept form of the equation:
x - y = 4
x - x - y = 4 - x
-y = 4 - x
-y = -x + 4
-y/-1 = -x/-1 + 4/-1 (to get the y positive)
y = x - 4
The y-intercept is -4. This means that a y-intercept two units above 4 would be -2. Whichever line crosses the y axis at the value of -2 is the answer (line B)
hope this helps :)
