Ron is designing a new slide for the amusement park in town. The slide makes an angle of 39 with the ground. The top of the slide

is to be 9 feet off the ground.

What should be the length of the slide he needs to make to the nearest foot?

A.25 feet

B.14 feet

C.28 feet

D.19 feet

Let x represent length of the slide.

We have been given that Ron is designing a new slide for the amusement park in town. The slide makes an angle of 39 with the ground. The top of the slide  is to be 9 feet off the ground. We are asked to find the length of the slide.

The slide will make a right triangle with respect to ground, where length of the slide will be hypotenuse, and height of the slide will be perpendicular with ground.    

We know that sine relates opposite side of right triangle with hypotenuse.

Upon rounding to nearest foot, we will get:

Therefore, the length of slide should be approximately 14 feet and option B is the correct choice.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
