Answer:

  97.42 square units

Step-by-step explanation:

The area of a sector is given by ...

  A = (1/2)r²θ

where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.

  75° = (75°)×(π/180°) radians = (5/12)π radians

Then the area is ...

  A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units

__

Equivalently, you can find the area of the circle in the usual way:

  A = πr² = π(12.2²) ≈ 467.59465

Then, multiply by the fraction of the circle that is shaded (75°/360°)

  sector area = (467.59465)(75/360) = 94.42 . . . square units

Step-by-step explanation:

3. 10x + 6 = 8x

   8x = 10x + 6

   -2x = 6

  x = -3

4. y = 8(1) - 5= 8 - 5 = 3

   y = 8(2) - 5 = 16 - 5 = 11

    y = 8(5) - 5 = 40 - 5 = 35

    y = 8(0) - 5 = 0 - 5 = -5

    y = 8(-1) - 5 = -8 - 5 = -13

[tex]10x + 6 = 8x[/tex]

[tex]6 = 8x - 10x[/tex]

[tex]6 = - 2x[/tex]

[tex]6 \div - 2 = x[/tex]

[tex] - 3 = x[/tex]

[tex]y = 8x - 5[/tex]

When [tex] x = 1, y = \bold{ 3} [/tex]

[tex]y = (8 \times 1)- 5[/tex]

[tex]y = 8 - 5[/tex]

[tex]y = 3[/tex]

When [tex] x = 2, y = \bold{ 11} [/tex]

[tex]y = (8 \times 2)- 5[/tex]

[tex]y = 16 - 5[/tex]

[tex]y = 11[/tex]

When [tex] x = 5, y = \bold{35} [/tex]

[tex]y = (8 \times 5)- 5[/tex]

[tex]y = 40 - 5[/tex]

[tex]y = 35[/tex]

When [tex] x = 0, y = \bold{-5} [/tex]

[tex]y = (8 \times 0)- 5[/tex]

[tex]y = 0 - 5[/tex]

[tex]y = - 5[/tex]

When [tex] x = -1, y = \bold{-13} [/tex]

[tex]y = (8 \times - 1)- 5[/tex]

[tex]y = - 8 - 5[/tex]

[tex]y = - 13[/tex]

Answer:

x < 33/4

Step-by-step explanation:

1.) -4x+35 > 2 (Move the constant to the right-hand scale side and change its sign)

-4x > 2 - 35

2.) -4x > 2 - 35 (Calculate the difference)

4x > -33

3.) -4x > -33 (Divide both sides of the inequality by -4 and flip the inequality sign)

x < 33/4

Step-by-step explanation:

Answer:

The two angles are 69° and 21°.

Step-by-step explanation:

Write out the expression:

let x and y be two angles that are complementary and the sum of their measures is 90°

-> x° + y° = 90°

if one angle is 6º more than three times the other angle:

-> x° = 6° +3y°

Plug x = 6+3y into x° + y° = 90°

6° + 3y° + y° = 90°

Solve for y

4y° = 84°

y° = 21°

Plug y into x° + y° = 90°

x° + 21° = 90°

Solve for x°

x° = 90° - 21° = 69°

Answer:

2.8 i think

Step-by-step explanation:

Answer:

on the bottom equation you can subtract 1 from both sides, x = 2y+1 so you substitute that in for x on the other equation, 7(2y+1) - 2y = 1 or 14y + 7 -2y = 1 then 12y = -6 y = -1/2 which you put back into the other equation, 2(-1/2) = x -1 so -1 = x - 1 then x = 0, the answer is (0, -1/2)

Jan is not correct. The opposite of any number will not always be a positive. This is because the opposite of a positive number is negative and the opposite of a negative number is positive.

Basically, opposite numbers are numbers that are the same distance to 0 on a number line. If we were to have a positive 1, the opposite of that number would be a -1, because that's equally distant from 0 on a number line.

Answer:

The first one is 360 degrees. The second one is 1080.

Step-by-step explanation:

The sum of the interior angles of a quadrilateral are always 360. If you subtract 90 from 360 to get 270. Multiply 270 by 4 to get 1080.

Answer:

85 ounces

Step-by-step explanation:

A strange bowling bow is made up of plastic and wood. The weight of the two materials are in a ratio of 5 to 9 if the bowling ball weights 238 ounces what is the weight of the plastic.

We are given the ratio:

Plastic : wood

5:9

Sum of proportion = 5 + 9 = 14

The weight of the bowling ball = 238 ounces

Hence

The weight of the plastic is calculated as:

5/14 × 238 ounces

= 85 ounces

Step-by-step explanation:

Answer:

23 units

Step-by-step explanation:

Let the vertices of the triangle be A(5,6), B(4,1) and C(-4,2)

Perimeter of the triangle = AB + AC + BC

AB = √(5-4)²+(6-1)²

AB = √1²+5²

AB = √1+25

AB = √26

For BC where B(4,1) and C(-4,2)

BC = √(4-+4)²+(1-2)²

BC = √8²+1²

BC = √64+1

BC = √65

For AC where A(5,6) and C(-4,2)

AC = √(5+4)²+(6-2)²

AC = √9²+4²

AC = √81+16

AC = √97

Perimeter = √97 + √26 + √65

Perimeter = 9.85+5.09+8.06

Perimeter = 23

Hence the perimeter of the triangle is approx 23 units

Answer:

4/7 of her total time cleaning the kitchen

Step-by-step explanation:

Olivia does chores every Saturday morning. She spends 1/3 of her time cleaning her room. Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?]

Let

x = her total time

Room cleaning = 1/3x

Time remaining = 2/3x

Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen.

Kitchen cleaning = 6/7 of 2/3x

= 6/7 * 2/3x

= (6*2)x/(7*3)

= 12/21x

= 4/7x

Olivia spent 4/7 of her total time cleaning the kitchen

Answer: D. 18

Step-by-step explanation:

Answer:

60 meters, see explanation.

Step-by-step explanation:

We know that the ratio of length : width is 10 : 6. So for every 10 meters of length, we also have 6 meters of width. This problem is much easier since we are given the P = 160 meters.

You can see that if we multiply the ratio by ten, we get 100 : 60, where 100 + 60 = 160 total meters. From here, it is clear that the width would be 60 meters.

Answer:

3.) All complementary angles form a right angle.

hope this helps you :)

"All complementary angles form a right angle" is not Euclid's postulates. Therefore, option C is the correct answer.

We need to identify which of the given option is not one of Euclid’s postulates.

A statement, also known as an axiom, is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived. The whole of Euclidean geometry, for example, is based on five postulates known as Euclid's postulates.

Postulate 1: A straight line may be drawn from any one point to any other point.

Postulate 2:A terminated line can be produced indefinitely.

Postulate 3: A circle can be drawn with any centre and any radius. Postulate 4: All right angles are equal to one another.

From the about options we can draw a conclusion that "All complementary angles form a right angle" is not Euclid's postulates.

Therefore, option C is the correct answer.

I think it is 13/15 (0,8666666...) but I am not sure

Answer:

12/15 or if u simplify it then you'll get 4/5

Step-by-step explanation:

3 2/3 multiplied by 5 bc u would need to find an equivalent fraction then 3 2/3 will turn into 55/ 15 and 2 4/5 will be multiplied by 3 and turned into 43/15. After that then u would substract 55/15 by 43/15 and u will end up with 12/15 and if simplified then it would be 4/5
