A sector of a circle of diameter 11 cm is formed from an angle of size 51. Find the length of the arc rounded to two decimal places

Answers

Answer 1

Answer:

4.90m

Step-by-step explanation:

A sector of a circle of diameter 11 cm is formed from an angle of size 51. Find the length of the arc rounded to two decimal places

Length of an arc = 2πr(θ/360)

(θ) = 51°

r = Diameter/2 = 11/2

= 5.5

Length of an arc = 2 × π × 5.5(51/360)

= 4.89565m

Approximately = 4.90m

C -2x+2y=-3
2x-3y=-1

D 3x+3y=9
2x-3y=-1

Answers

The answer to the question is B

Answer:

Step-by-step explanation:

In order for us to be able to find our answer, we need to show our work.

-3(x-y=3) → -3x + 3y = -9

                 +2x - 3y = -1

____________________________

                  -1x = -10

                   -1      -1

We need to divide -1 both sides in order for us to be able to find our x-value but there's more to this than just solving for X.

x = 10

x - y = 3

10 - y = 3

-10       -10

_________________

-y = -7

-1     -1

We need to divide -1 both sides in order for us to be able to find our y-value. Please note that each y is equivalent to an invisible 1.

y = 7

As a result, your answer will be B.

Diego is asked to solve 3x−8=4(x+5). What do you recommend he does to each side first?

Answers

Answer:

He would factor out 4(x+5)

Step-by-step explanation:

You can't do much until the 4(x+5) is factored out.

Once it is then it'd be 3x-8=4x+20

Then you subtract 3x on both sides and subtract 20 on both sides.

You'd be left with -28=x

Determine whether this situation represents independent or dependent events. "Three green jelly bean, five red jelly beans and two orange jelly bean are in a bag. What is the probability of selecting an orange jelly bean, putting it back, and then selecting a green jelly bean?" Question 1 options: Independent Events Dependent Events

Answers

Answer:

Independent Events

Step-by-step explanation:

Given

[tex]Green = 3\\ Orange = 2\\ Red = 5[/tex]

Required

Dependent or independent event

The probability of selecting a green jelly remains unchanged before and after selecting the first orange jelly.

Before selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

After selecting the orange jelly:

[tex]P(Green) = \frac{Green}{Total}[/tex]

[tex]P(Green) = \frac{3}{10}[/tex]

Because the probabilities remain unchanged, the selection of a green jelly is independent of the selection of the first orange jelly.

9.) cos(A) = 1.2608
10.) sin(A) = 0.7777
11.) sin(A) = 1.8330

Answers

Answer:

82° ; 50° ; 52° ;domain error ;51° ; domain error

Step-by-step explanation:

Using a calculator :

sin(A) = 0.9903

A = sin^-1(0.9903) = 82.01 = 82°

6.) cos(A) = 0.6428

A = cos^-1(0.6428) = 49.99 = 50°

8.) tan(A) = 1.2851

A = tan^-1(1.2851) = 52.111 = 52°

9.) cos(A) = 1.2608

A = cos^-1(1.2608) = domain error

10.) sin(A) = 0.7777

A = sin^-1(0.777) = 50.98 = 51°

11.) sin(A) = 1.8330

A = sin^-1(1.8330) = domain error

You have $10.00. Each week you
save $2.50. The number of weeks
you save w increases your
savings s.
Write an equation relating your savings s to the number of weeks you save w.

help me make the equation please

Answers

answer:

s= 10 + 2.50w

explanation:

the amount of money in your savings is equal to the initial $10 you had before you started saving 2.50 per week. weak week $2.50 is added to the savings. 2.50w can be seen as 2.50 times the amount of weeks. say you were 3 weeks into saving, you would do 10 + 2.50(3) to find the amount of money you have.

4 solve the following simultaneous equations using elimination method:
(iii) 2x - y = 2, 5x + y = -9

Answers

Step-by-step explanation:

As instructed

Use Elimination Method....

2x - y = 2

2x - 2 = y

y = 2x - 2 ----------- equation 1

5x + y = -9

Substitute for y

5x + 2x - 2 = -9

7x = -9 + 2

7x = -7

x = -7/7

x = -1

Substitute for x in equation 1

y = 2x - 2

y = 2(-1) - 2

y = -2 - 2

y = -4

Answer:

(- 1, - 4 )

Step-by-step explanation:

Given the 2 equations

2x - y = 2 → (1)

5x + y = - 9 → (2)

Adding the 2 equations term by term will eliminate the y- term, that is

7x + 0 = - 7

7x = - 7 ( divide both sides by 7 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

5(- 1) + y = - 9

- 5 + y = - 9 ( add 5 to both sides )

y = - 4

solution is (- 1, - 4 )

Video club A charges $10 for membership and. $4 per movie rental. Video club B charges $15 for membership and $3 per movie rental. For how many rentals will be cost be the same at both video clubs? What is that cost?

Answers

Answer:

5 rentals for $30

Step-by-step explanation: *using y = mx + b*

Info Given:

Video Club A-

$10 (would be your b)

$4 (would be your x)

Video Club B-

$15 (would be your b)

$3 (would be your x)

HOW TO SOLVE:

Video Club A - y = 4x + 10

Video Club B - y = 3x + 15

Set them equal to eachother to solve for x!

4x + 10 = 3x + 15

     - 10         - 10

4x = 3x + 5

-3x -3x

x = 5 rentals

Plug in the x into both or just one equation to find the price!

y = 4x + 10

  = 4(5) + 10

  = 20 + 10

y = $30

Answers

Answer:

Step-by-step explanation:

Angle 1 is equal to angle 3 because they are opposite each other so

Angle 1=43 degrees

Angle 1 and angle 2 have a sum of 180 degrees because they are adjacent to each other.

angle 2=180-43=137 degrees.

angle 2 and 4 are opposite each other so they are equal

angle 4=137 degrees.

Answer:

Angle 1 = 43°

Angle 2 = 137°

Angls 4 = 137°

Step-by-step explanation:

To get angle 1, l and m intersect and there are two angles which cause vertical opposite angles. When there are vertical opposite angles, both angles have the same degree. For angle 2, you need to find angle 1 and 3, after that you deduct both angle 1 and 3 from 360° which is the angle of whole figure. 360 - 43 - 43 = 274° for angle 2 and 4, since they're also vertically opposite angles, both 2 and 4 have the same angle. All you need to do to find 2 and 4 is 274 ÷ 2 = 137°.

Answer:

Step-by-step explanation:

Hey There!

The first step in solving this problem is finding the formula for area of a trapezoid

[tex]A = \frac{a+b}{2} h[/tex]

a = base 1

b = base 2

h = height

For the first one the dimensions are

a = 6

b = 9

h = 4

now we just plug in the values

[tex]A=\frac{6+9}{2} 4\\6+9=15\\\frac{15}{2}=7.5\\7.5*4=30[/tex]

so the area of the first trapezoid is 30 ft²

For the second one the given dimensions are

a = 8

b = 11

h = 6

now we just plug in the values

[tex]A=\frac{8+11}{2} 6\\8+11=19\\\frac{19}{2} =9.5\\9.5*6=57[/tex]

so the area of the second trapezoid is 57 yd²
