Find the area of a sector with a central angle of 140° and a diameter of 9.6 cm. Round to the nearest tenth.

Answers

Answer 1

Answer:

[tex]A=28.1\ cm^2[/tex]

Step-by-step explanation:

The area of a circular sector with a central angle θ and radius r is given by:

[tex]\displaystyle A=\frac{1}{2}r^2 \theta[/tex]

Note: The angle must be in radians.

We need to find both the radius and the angle in radians.

Diameter = 9.6 cm

Radius r=Diameter/2=4.8 cm

Angle in radians= Angle in degrees*π / 180

θ = 140*π / 180 = 2.4435 rad

Now we calculate the area:

[tex]\displaystyle A=\frac{1}{2}(4.8)^2 2.4435[/tex]

[tex]\boxed{A=28.1\ cm^2}[/tex]

Answers

Answer:

D: 8/6

Step-by-step explanation:

Slope = y 2 - y 1

x2 - x1

= 8 - 0

6 - 0

=8

6

Answer: D. 8/6

Step-by-step explanation:

To solve this, we can use the slope formula, which is  

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]      ← this is [tex]\frac{rise}{run}[/tex]

Plugging in the values of the two points, we get:

[tex]\frac{8 - 0}{6 - 0} = \frac{8}{6} = \frac{4}{3}[/tex]

In your case though, it is D. 8/6

© Stephen was thinking of a number. Stephen doubles it, then adds 11 to get an
answer of 47.7. What was the original number?

Answers

Answer:

18.35

Step-by-step explanation:

This is a question which requires you to work backwards.

Divide  means multiply and vice versa

Addition  means subtract and vice versa

First, we find the number before 47.7.

47.7-11=36.7

Secondly, we find the number before 36.7, aka the original number.

36.7/2=18.35 (/ sign means divide)

“3. Solve for x. Do not forget the statements and reasons.”

Answers

Answer:

x = 6

Step-by-step explanation:

In order to find the value of x, first we need to prove the triangles PQS and RQS as congruent. Let us do it.

[tex] In\: \triangle PQS \:\& \:\triangle RQS\\\\

PS \cong SR.... (given) \\\\

\angle PSQ \cong\angle RQS... (\because QS\perp PR) \\\\

QS \cong QS... (Common \: side) \\\\

\therefore \triangle PQS \cong \triangle RQS.. (SAS \: Postulate) \\\\

\therefore PQ = QR... (BY\:CSCT) \\\\

\therefore 2x + 15 = 5x - 3\\\\

\therefore 2x - 5x = - 3 - 15\\\\

\therefore - 3x = - 18\\\\

\therefore x =\frac{-18}{-3}\\\\

\huge \red {\boxed {\therefore x = 6}} [/tex]

x=6

Both sides need to equal out to the same number

2•6 = 12
12+15= 27

5•6= 30
30-3= 27

Both sides equal out to the same number so 6 would be the correct answer.

Solve for x 5z-8=-28

Answers

U said solve for x do u mean z?

z=-4

Answer: z = -4

Step-by-step explanation:

Simplifying

5z + -8 = -28

Reorder the terms:

-8 + 5z = -28

Solving

-8 + 5z = -28

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 5z = -28 + 8

Combine like terms: -8 + 8 = 0

0 + 5z = -28 + 8

5z = -28 + 8

Combine like terms: -28 + 8 = -20

5z = -20

Divide each side by '5'.

z = -4

Simplifying

z = -4    Hope this helps !

Ibai has taken 2/5 out of a barrel of beer, Ane has drawn a third. It expresses in graphic and numerical form: a) The fraction that they have drawn between the two. b) Which of them has gotten the most?

Answers

Answer:

7/15

Step-by-step explanation:

2/5 + 1/3 is the same as 2/5 + 5/15.. so we add them together to get 7/15. This can not be simplified further

To know who has gotten most I like to think in percentage terms. 2/5 is the same as 40% (2/5 is the same as 4/10 = 40/100 =40%). 1/3 is 33.33% so Ane got more

Answer:

A. 11/15 B. Ibai.

Step-by-step explanation:

First, find the Least Common Multiple, or LCM, of the denominators, which is 15. Then, multiply each denominator by the number that gets the denominator to 15, which is the LCM. Next, multiply the numerator by the same number you multiplied the denominators, which was 3 for Ibai, and 5 for Ane. Finally, compare the two numbers to see which is higher. In this case, Ibai took out 6/15, while Ane took out 5/15, meaning Ibai took out more than Ane. Also, together, Ibai and Ane both drew out 11/15 together.

Sue wants to put a rectangular garden on her property using 88 meters of fencing. There is a river that runs through her property so she decides to increase the size of the garden by using the river as one side of the rectangle. (Fencing is then needed only on the other three sides.) Let x represent the length of the side of the rectangle along the river. Express the garden's area as a function of x. what is the largest area that can be enclosed?

Answers

Answer:

Area = 44x - x²/2

Step-by-step explanation:

Given that:

Meter of fencing = 88m

Length of side of rectangle along the river = x

Only one more length is needed since river as been used as one side length of the fence.

Length = x

Width of rectangle = y = 2y (for both sides)

Hence ;

x + 2y = 88 meters

Expressing in terms of y

2y = 88 - x

y = (88 - x) / 2

y = 44 - x/2

Area of rectangle = Length * width

Area = x * y

Area = x * (44 - x/2)

Area = 44x - x²/2

Maximum. Area :

Perimeter = 4s

88 = 4s

s = 88/4 = 22

x = 2(22) = 44 = Length ; y = 22 = width

Maximum area = (22 * 44) = 968m²
