The radius of a circle is 8 feet. What is the area of a sector bounded by a 144° arc?

Answers

Answer 1

Answer:

[tex] A_{sector} \approx \: 80.38 \: {ft}^{2} [/tex]

Step-by-step explanation:

[tex] A_{sector} = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ A_{sector} = \frac{144 \degree}{360 \degree} \times 3.14 \times {(8)}^{2} \\ \\ A_{sector} = 0.4 \times 3.14 \times {(8)}^{2} \\ \\ A_{sector} = 80.384 \\ \\ A_{sector} \approx \: 80.38 \: {ft}^{2} [/tex]

twice the number of xylophones.
How many yodelers and how many
xylophones are on the gondola? Represent this problem with a system of equations. Let x represent the number of xylophones and let y be the number of yodelers.

I need help on how to fill a deposit slip, please someone help with details and dont abuse for points.. I want to learn how rather than give the answer.

Answers

Just start by filling out the things you know. So your name and the date. After that there’s a thing on the right hand side that says bills, coins, checks and that depends on what you are putting in the bank so for this it would be a checks since you’re depositing a check. The 1600 would go in the checks area and you would just do nothing in the bills and coins part (usually you’ll cross it out so that nobody can write anything there). After that write the total, which for this it’s just 1600 but if you had more than one check or money bills that you were putting in you just add them together. Then less cash is where you would put the 800 because that’s what you’re taking out of the bank and your net deposit is just the total you have in your bank account after you deposit and withdraw money. And then once you finish that they’ll usually ask you to sign it just to say that they deposited and withdrew the correct amount of money that you asked.

Subtract the sum of 12xy –10y2 –18x2 and 9xy + 12y2 + 14x2 from the sum of
xy + 2y2 and 3y2 – x2.

Answers

Answer: -20xy + 3y² + 3x²

Step-by-step explanation:

(xy + 2y² + 3y² - x²) - (12xy - 10y² - 18x² + 9xy + 12y² + 14x²)

(xy + 5y² - x²) - (21xy + 2y² - 4x²)

xy + 5y² - x² - 21xy - 2y² + 4x²

Answers

Slope (3) y intercept (0,-2)

Answer: y = 3x -2

Slope =3

Y-intercept = -2

Step-by-step explanation:

2y+8 = 6x + 4

Subtract 8 on both sides.

2y = 6x -4

Divide by 2. 2y divided by 2 leaves just y. 6x divided by 2 is 3x. -4 divided by 2 is -2.

Answer:

91.5 ft

Step-by-step explanation:

AS = BH AS= area of square

AS = (14) (6)

AS = 84

7ft + 4ft = 11ft

14ft - 11ft = 3ft

base of the triangles = 3ft

AT = BH/2 AT = area of triangle

AT = (3)(5)/2

AT = 7.5

TA = 84 + 7.5 TA = total area

TA = 91.5

Answer:

Area is 91.5ft squared

Step-by-step explanation:

6 * 14 = 84

The rectangle is 84ft.

7 + 4 = 11

14 - 11 = 3

5 * 3 = 15

15 / 2 = 7.5

84 + 7.5 = 91.5

Area is 91.5ft squared
