Answer:
x ≈ 16.52
Step-by-step explanation:
Use the tangent ratio in the right triangle to find x
tan36° = 
= 
Multiply both sides by x
x × tan36° = 12 ( divide both sides by tan36° )
x = 12 / tan36° ≈ 16.52 ( to 2 dec. places )
Answer:
Step-by-step explanation:
The probability of drawing a red card is 1/2, since half of the cards in a deck are red. The probability of drawing an ace from a deck is 1/13, since there is an equal chance to pick any of the 13 numbers.
P(red card and ace)= P(red card)*P(ace)=1/2 * 1/13=1/26
It's a parabolic curve, so quadratic is best
You can put it in a calculator, or do long division on a piece of paper. I would show you how to break it down step-by-step, but doing long division on here is complicated.
All you have to do is find the decimal of a fraction is to divide the numerator and the denominator.
In this case, divide 37 by 40 to get your decimal.
37 ÷ 40 = 0.925
So, the decimal form of 37/40 is 0.925.
