Jake built a skateboard ramp, if the distance of the ramp is 10 ft. The ramp rises a
ikadub [295]

Answer:

Angle made by ramp with ground is ≈19.29^{\circ}

Step-by-step explanation:

Diagram of given scenario is shown below.

Given that,

Horizontal Distance of Skateboard ramp is 10 ft.

Height of Skateboard ramp is 3.5 ft.

From figure,

It is forming a Right angle triangle \triangle ABC.

In \triangle ABC, AB=3.5 and BC=10.

Clearly see that we need to find measure of angle \angle C.

Using Trigonometric ratio:

     Tan(\theta)= \frac{Perpendicular}{Base}

So,  Tan(\angle C) = \frac{AB}{BC} =\frac{3.5}{10} =0.35

Then \angle C=Tan^{-1} (3.5)=19.290046^{\circ}

Therefore, Angle made by ramp with ground is ≈19.29^{\circ}

12. What is the probability that a point in the square below
andrew-mc [135]

Answer:

21.5\%

Step-by-step explanation:

we know that

The probability that a point in the square below  is in the shaded region, is equal to divide the area of the shaded region by the area of the square

step 1

Find the area of the shaded region

The area is equal to the area of the square minus the area of the circle

A=b^{2} -\pi(r)^{2}

we have

b=12\ cm ---> length side of the square

r=12/2=6\ cm ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=12^{2} -(3.14)(6)^{2}

A=30.96\ cm^{2}

step 2

Find the area of the square

A=b^{2}

we have

b=12\ cm ---> length side of the square

substitute

A=12^{2}=144\ cm^{2}

step 3

Find the probability

P=30.96/144=0.215

Convert to percent form

0.215*100=21.5\%
