A wheelchair ramp rises from the ground at a 4.5 degree angle of elevation. The end of the ramp is 3 ft. above the ground. How l
Doss [256]
<span>the longitude of the ramp is determined by the Hypotenuse, we have the angle(4.5Âş), and the opposite side (3ft), so with the Sin(x) trigonometric function ( sin(x)=opposite/hypotenuse ) we can calculate the answer.
 Using the formula, hypotenuse=opposite/sin(x)
Hypotenuse=3ft/sin(4.5)
 hypotenuse=3ft/0.0784591
 hypotenuse=38.236482
   the ramp must be 38.2 ft long. the calc must be in degrees to get an accurate answer to any trigonometric function</span>

Lee is comparing brands of juice. Brand A
maxonik [38]
<h3>Answer: 3 bottles of brand A</h3>

Explanation:

The pricing/cost information is not used in this problem. All we care about is the number of bottles, and how much each bottle can hold.

Brand A bottles hold 0.95 liters each. We bought 3 of these bottles, so 3*0.95 = 2.85 liters in total are purchased.

Brand B bottles hold 0.55 liters each. Buying 5 of them leads to 5*0.55 = 2.75 liters in total.

Going with the brand A option leads to more juice by 0.10 liters (subtract 2.85 and 2.75)
