Her fuel tank is not empty. She added 3/4 gallon of fuel and used 2/4 which still leaves 1/4 gallon left. If she had only put 1/2 a gallon, it would have been empty.
Answer:
The answer is C.
Step-by-step explanation:
1/2 x 4/1 = ?
We begin by multiplying the numerators:
1 x 4 = 4
And then we multiply the denominators:
2 x 1 = 2
The answer has a numerator of 4 and a denominator of 2. In other words:
1 x 4/2 x 1 =4/2
This fraction can be reduced to lowest terms:
4 ÷ 2/2 ÷ 2 =2/1 = 2
Answer:
tan (C) = 2.05
Step-by-step explanation:
Given:
A right angled triangle CDE right angled at ∠D.
Side CD = 39
Side DE = 80
Side CE = 89
We know, from trigonometric ratios that, the tangent of any angle is equal to the ratio of the opposite side to the angle and the adjacent side of the angle.
Therefore, tangent of angle C is given as:
Plug in the given values and solve for angle C.This gives,
Therefore, the measure of tangent of angle C is 2.05.
