Answer:

28.27 inches^{2}

Step-by-step explanation:

To work this out you would first have to work out the area of the larger circle. You can achieve this by firs dividing the diameter of 10 by 2, which  gives you 5. This is because the radius is half of the diameter. You would then have to multiply pi by the radius of 5 squared, which gives you 78.54. Then the next step it is to work out the area of the smaller circle. To do this you would first need to divide the diameter of 8 by 2 to work out the radius, which gives you 4. Then you would multiply pi by the radius squared. which gives you 50.27. The final step is to minus 50.27 from 78.54, this gives you 28.27.

The formula for the area of a circle is : \pi *radius^{2}

1) Divide 10 by 2.

10/2=5

2) Multiply pi by 5 squared.

\pi *5^{2}=78.54

3) Divide 8 by 2.

8/2=4

4) Multiply pi by 4 squared.

\pi *4^{2} =50.27

5) Minus 50.27 from 78.54.

78.54-50.27=28.27

Gina wants to ride the waves at flagship pier in Galveston so she rents a surfboard for 5$ per hour plus an initial or beginning
Aneli [31]
If Gina has $90 and pays:

$20 for beginning
$5 per hour

Then 90 - 20 is 70. 70 divided by 5 is 14.

She can rent a surfboard to surf for 14 hours.

Answer this question I will Mark brilliant and gets 70 PTS <br>do number one or two or do both ​
yanalaym [24]

Answers And Explanations:

Question 1.

Pulling out like terms :

1.1     Pull out like factors :

  12y - 10  =   2 • (6y - 5)  

Equation at the end of step  1  :

  Divide both sides by  2  

 

 Divide both sides by  6  

 y-(5/6)  > 0

Add  5/6  to both sides

y > 5/6.

Therefore, y = 5/6

__________________________________

Question 2.

To make fractions improper with whole numbers, you must <u>multiply the Denominator by the whole number, then add the Numerator to the Product.</u>

<u></u>

First we multiply 32 by 5.

32 x 5 = 160.

Then we add the Numerator which is 1.

160 + 1 = 161, then we put it over the Denominator, your final answer is 161/5.

Therefore, 161/5 is your final answer.

Have any questions? Feel free to comment below!

Thank you and Best of Luck to you!

At what angle does a diffraction grating produce a second-order maximum for light having a first-order maximum at 20.0 degrees?
hichkok12 [17]

Answer:

At 43.2°.

Step-by-step explanation:

To find the angle we need to use the following equation:

d*sin(\theta) = m\lambda

Where:

d: is the separation of the grating

m: is the order of the maximum

λ: is the wavelength

θ: is the angle              

At the first-order maximum (m=1) at 20.0 degrees we have:

\frac{\lambda}{d} = \frac{sin(\theta)}{m} = \frac{sin(20.0)}{1} = 0.342

Now, to produce a second-order maximum (m=2) the angle must be:

sin(\theta) = \frac{\lambda}{d}*m

\theta = arcsin(\frac{\lambda}{d}*m) = arcsin(0.342*2) = 43.2 ^{\circ}

Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.    

I hope it helps you!
