Add all of the possible outcomes which is 130. Take the amount of circle cards and put that number in the numerator. So, 91/130 and divide. Which equals .7 so, move the decimal two places to the right to get 70% chance of selecting a circle card.
By=x+2, as this is the only equation that shows the relation between 2 variables
117? if you are looking for the sum.
Answer: Approximately 8.49 feet
==================================================
Explanation:
Draw a right triangle. The reference angle is between the ground and the kite string (aka hypotenuse). The hypotenuse is 12 and the side opposite the reference angle is x.
Refer to the diagram below.
We'll use the sine rule to find x
sin(angle) = opposite/hypotenuse
sin(45) = x/12
12*sin(45) = x
x = 12*sin(45)
x = 8.48528137423857
x = 8.49
This value is approximate.
Make sure your calculator is in degree mode.
I rounded to 2 decimal places, but feel free to round however you need if your teacher instructs otherwise.
I believe it is 2x^2 - 3x - 1
