19. Jessie is building a ramp for loading motorcyclesonto a trailer. The trailer is 2.8 feet off of the
ground. To avoid making it too difficult to push a
motorcycle up the ramp, Jessie decides to make the
angle between the ramp and the ground 159. To the
nearest hundredth of a foot, find the length of the
ramp.
A. 10.82 feet
B. 2.90 feet
C. 0.72 feet

Answer 2
Answer:

Final answer:

When using trigonometry to solve for the length of a ramp given the height of the trailer and the angle of the ramp, we use the sine of the angle, defined as the ratio of opposite side to the hypotenuse. The length of the ramp, or hypotenuse, was found to be approximately 0.72 feet.

Explanation:

This question is about trigonometry, a branch of mathematics that deals with the relationships between the sides and angles of triangles. In this case, we are given the height of the trailer (2.8 feet) and the angle between the ramp and the ground (159 degrees).

We are asked to find the length of the ramp, which is the hypotenuse of the triangle formed by the ramp, the ground, and the trailer. This can be found by using the sine of the angle, defined as the ratio of the opposite side (the height of the trailer) to the hypotenuse (the ramp length).

Using the equation sin(159) = 2.8 / ramp-length and solving for ramp-length by multiplying both sides by ramp-length and then dividing by sin(159), we find that the length of the ramp is approximately 0.72 feet.

So, the correct answer is C. 0.72 feet.

(please help.. it's urgent. thanks <3)

Answers

The higher value of X is associated with a lower value of Y so this is a negative association. It is also a nonlinear association because the ratio of change is not constant. For example X changes from 1 to 2, Y changes from 120 to 115 opposed to X changes from 5 to 6 while Y changes from 89 to 40.

If a cone-shaped vase can hold 45 cubic centimeters of water and has a radius of 2 centimeters, what is the height of the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answers

Answer:

3.58

Step-by-step explanation:

45cm3= 2 squared x height x 3.14

So you take 45 and divide it by 2 squared which is 4 and 3.14. Then you would get 3.582 and round it to 3.58

Answer:

13.14

Step-by-step explanation:

v= 1/3 pi r^2 h

45 = 1/3 (3.14) (4) h

45 = 1/3 (12.56) h

45 = 1/3 12.56/ 4 = 4 h/4

h = 3.14

45 = 1/3 (12.56)  (3.14)

45 = 1/3 (39.44)

45 = 39.44/3 = 13.14
