is the area of the shaded region?

Both Circles Have The Same Center. The Circumference Of The Inner Circle Is 150.72 Feet. Whatis The Area

Answers

Answer 1

Answer:

Step-by-step explanation:

The circumference = 2 * pi * r = 150.72

Use this fact to find r

2*pi*r = 150.72              Divide by pi

2*r = 150.72 / 3.141

2*r =  47.985                 Divide by 2

r = 23.9923

Now that you have the radius of the inner circle, use it to find the area.

Area = pi * r^2

Area = 1808.064

Now we need the radius of the outer circle

r = 23.9923 + 11

r = 34.9923

Find the area of the other circle

Area = pi * 34.9923^2

Area = 3846.032

Finally the area of the shaded region is the area of the large circle - the area of the small circle

Area of the shaded area = 3846.032 - 1808.064

Area of the shaded area = 2037.97 to the nearest hundredth.

1. Henry is using a total of 40 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each 8 ft. high. The top, bottom, and two shelves are all the same length, labeled .

Part A: Construct an equation to model the situation. (5 points)




Part B: Solve the equation. Show all your steps.

(5 points)





Part C: Use the solution to answer the question in a complete sentence. (5 points)

Answers

Answer:

Part A:

40 = 16 + 4·s

Part B:

The length of the top and bottom and the two shelves are each = 6 ft.

Part C:

The width of the bookshelf is 6 feet

Step-by-step explanation:

The given parameters are;

The length of the lumber Henry is using to make the book case = 40 ft.

The height of the left and right side of the book case = 8 ft. each

The length of the top and bottom and the two shelves are each = s

Therefore, we have;

Part A:

The equation is given as follows;

40 = 8 × 2 + 4·s = 16 + 4·s

40 = 16 + 4·s

Part B:

The solution of the equation is given as follows;

40 = 16 + 4·s

4·s= 40 - 16 = 24

s = 24/4 = 6 ft.

s = 6 ft.

The length of the top and bottom and the two shelves are each = 6 ft.

Part C:

The width of the bookshelf is 6 feet

> n volunteers who didn't donate

> 470 mL each

So your expression is: 470(32 - n).

Why?

Subtract the 32 volunteers who want to donate blood from the volunteers who were not able to donate then multiply it by 470.

Answer:

8. x=18  9. x=33   10. x=65  11. x=19  12. x=59

Step-by-step explanation:

8.  The angles are essentially vertical so they have to be equal to each other.

42=2x+6   subtract 6 from both sides  36=2x   x=18

9.  These angles are supplementary and equal 180 when added together.

98+(3x-17)=180  subtract 98 and add 17 to both sides  3x=99  x=33

10.  Angles are essentially vertical so they are equal to each other.

2x+2=3x-63  add 63 to both sides subtract 2x from both sides  65=1x

11.  Angles are supplementary so they equal 180 when added together.

112+(4x-8)=180 subtract 112 and add 8 to both sides   4x=76   x=19

12.  Angles are vertical so they are equal to each other.

(3x-33)=(2x+26)  add 33 to both sides and subtract 2x   59=1x

Help Needed!! Find The Measure Of Angle A In The Triangle

Answers

Answer:

A=40°

Step-by-step explanation:

All angles in a triangle add up to 180°, so we take 60 away from 180 because we know that angle.

180-60=120

Next, we add up the number of x,

10x+20x=30x

Third, we need to find out what x is, so we divide 120 by 30, which gives us 4.

x=4

to find out what 10x is (A), we multiply 4 by 10

4×10=40

A=40

Danice is reselling concert tickets and wants to markup the price at `\frac{1}{6}` of the original price, $231.00. What is the markup price for the concert ticket. Show all your steps.

Answers

Given:

Original price = $231.00

Markup price is [tex]\dfrac{1}{6}[/tex] of the original price.

To find:

The markup price for the concert ticket.

Solution:

It is given that, markup price is [tex]\dfrac{1}{6}[/tex] of the original price. So,

[tex]\text{Markup price}=\dfrac{1}{6}\times \text{Original price}[/tex]

[tex]\text{Markup price}=\dfrac{1}{6}\times 231[/tex]

[tex]\text{Markup price}=\dfrac{231}{6}[/tex]

[tex]\text{Markup price}=38.5[/tex]

Therefore, the markup price for the concert ticket is $38.5.
