A is numerical
b is algebraic
c is numerical
Triangle on the right is 45 45 90 right triangle
Ratio of leg : hypo = a :a√2
Given hypo = 6 so leg = 3√2
As you know leg of triangle on the right is the hypo of the triangle on the left
Triangle on the left is 30 60 90 right triangle
Ratio of short leg :hypo = a : 2a
You know hypo = 3√2 so leg x = (3√2 ) / 2 = 3√2 / 2
Answer is A. 3√2 / 2
It’s c just to let you know I have done this before
The answer is 47 minutes.
You basically imagine this: Debra has a phone card for $30. She used x minutes every 16 cents. You end up with $22.48.
30 - (0.16x) = 22.48
You can basically graph that equation and the x-intercept will show you your answer. x = 47
