Let

x ----> the angle in degrees

we know that

$sin(x)=0.42$

Find the measure of angle x

Using a calculator

$x=sin^{-1}(0.42)=24.83^o$

A water wheel has a radius of 9 feet. The wheel is rotating at 5 revolutions per minute. Find the linear speed, in feet per mi

guajiro [1.7K]

Answer:

$90\pi\text{ ft/s}\approx282.74\text{ ft/s}$

Step-by-step explanation:

Refer to physics equation $v=\omega r$ , where $\omega$ is angular velocity.

Angular velocity's SI unit is rad/s. Convert rev/min to rad/s:

$\displaystyle 5\text{ rev/min}=5\cdot \frac{1}{60}\cdot 2\pi\approx 0.524\text{ rad/s}$

Now substitute $\displaystyle\omega=\frac{1\pi}{6}$ and $r=9$ into $v=\omega r$ :

$\displaystyle v=\frac{1\pi}{6}\cdot 9=\frac{3}{2}\pi\text{ ft/s}=\boxed{90\pi\text{ ft/s}}$

Yesterday morning Kathryn had 105 dollars. She first spent 1/3 of it at the mall. She counted her money. Later, she went to the

Katen [24]

Answer: she has $20 left now.

Step-by-step explanation:

The total amount of money that Kathryn had yesterday was 105 dollars.

She first spent 1/3 of it at the mall. This means that the amount of money that she spent at the mall is

1/3 × 105 = $35

The amount left after her shopping would be 105 - 35 = $70

Later, she went to the movies and spent 5/7 of what was left after her shopping. This means that the amount of money that she spent at the movies is

5/7 × 70 = $50

The amount that she has left now is

70 - 50 = $20
