Answer:

Height=9/2=4.5

A=1/2*b*h

A=1/2*6*4.5

A=13.5

13.5*2=27

The area of the shaded region is 27.

Find the coordinates of the center of the following circle.<br><br> (x - 3)² + (y - 7)² = 49

Zepler [3.9K]

When you write the equation of a circle in the form

$(x-x_0)^2+(y-y_0)^2=r^2$

Then the center of the circle has coordinates $(x_0, y_0)$ and the radius is $r$

So, in your case, the center of the circle is $(3,7)$

The differences are
2000 119

Due to the small size data set, it would not be appropriate to predict future years unless some proven method applicable to this case is used.

Someone please help me with this

Answer:

<em>50° is the correct answer</em>

Step-by-step explanation:

<u>Right Triangles</u>

The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.

We have a right triangle with the following characteristics:

The hypotenuse is 13 units long

The indicated angle is opposite to the leg of 10 units long.

When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:

$\displaystyle \sin\theta=\frac{\text{opposite side}}{\text{hypotenuse}}$

$\displaystyle \sin\theta=\frac{10}{13}$

Using a calculator set in mode <em>degrees</em>, the angle is:

$\theta=\sin^{-1}\frac{10}{13}$

$\theta\approx 50.3^\circ$

First choice: 52° is not correct because is not a good approximation to 50.3°

Second choice:38° is not correct because is not a good approximation to 50.3°

Third choice: 50° is a good approximation to 50.3°. Correct Answer

Fourth choice: 40° is not correct because is not a good approximation to 50.3°

Mark traveled 455 miles in 5 hours. At this rate how far could he travel in 7 1/2 hours

marshall27 [118]

Mark could travel 682.5 miles in 7.5 hours.

To solve this you have to find how fast he travels per hour.
455 miles/5 hours=91 mph
91 mph multiplied by 7.5 hours(91 x 7.5)= 682.5
682.5 Miles in 7.5 hours

Hope this helped you! :D
