8. Noah rides his motorcycle 90 miles in 2 hours 30 minutes. What is his average speed in

Nookie1986 [14]

Hey there! I'm happy to help!

We see that Noah rides his motorcycle 90 miles is 2 hours and 30 minutes, which is 150 minutes. We want to find his mph. To find this his mph, we want to find how far he has gone in one hour.

How much bigger is 150 than 60?

150/60=2.5

150 is 2.5 times bigger than 60. This means that we need to divide 90 by 2.5 to figure out how far Noah rode in 1 hour.

90/2.5=36

Therefore, Noah's average speed is 36 mph.

Have a wonderful day! :D

What is the measurement of angle A to the nearest degree?

forsale [732]

Answer:

A = 51 degrees

Step-by-step explanation:

We can use the law of sines

sin A sin 95

------------ = -----------

7 9

Using cross products

9 sin A = 7 sin 95

Divide each side by 9

sin A = 7/9 sin 95

Take the inverse of each side

sin ^-1 sin A = sin ^-1 ( 7/9 sin 95)

A = 50.78854367

To the nearest degree

A = 51 degrees

What is the measure of ∠BCD?<br><br><br><br> Enter your answer in the box.<br> °<br><br> PLSSS help

denpristay [2]

It seems to be a tilted square, so all angles are the same.
$103 \times 3$
so maybe just multiply by 3 and get 309 since B, C, and D are three angles.
$103 \times 3 = 309$
I might be wrong but, the answer should be 309.

How to find the circumference of a circle that is 42m and has diameter

Nitella [24]

Answer:

Circumference of the circle is $131.88m$

Step-by-step explanation:

we have to find the circumference of the given circle.

Given:

Diameter=42 m

$\\diameter=2*radius\\42 =2*radius\\radius=42/2\\radius=21 m$

Circumference of a circle= $2\pi r$

$=2*\pi *21\\=2*3.14*21\\=42*3.14\\=131.88$

So, the circumference of the circle is $131.88m$
