If a circle is divided into 30 equal parts, what will be the measure of the angle of each part???

Answers

Answer:

12 degrees

Step-by-step explanation:

Total angle in a circle = 360 degrees

If a circle is divided into 30 equal parts

measure of each part = Total angle in a circle/Total parts

measure of each part  = 360/30

measure of each part  = 12 degrees

Hence the measure of each part is 12 degrees

4b+5=1+5b
Anyone know it ??

Answers

Answer:

b = 4

Step-by-step explanation:

4b+5=1+5b

1️⃣Rearrange terms

4b+5=1+5b

4b+5=5b+1

2️⃣Subtract 5 from both sides of the equation

4b+5=5b+1

4b+5-5=5b+1-5

3️⃣Simplify

4b=5b-4

4️⃣Subtract 5b from both sides of the equation

4b=5b-4

4b-5b=5b-4-5b

5️⃣Simplify

-b=-4

6️⃣Divide both sides of the equation by the same term

-b=-4 subtract -1

7️⃣Simplify

b=4

Answer: b=4

In the circle below, Ab and CD are chords intersecting at E if AE=5, BE,12, and CE=6, what is the length of DE

Answers

Answer:

DE = 10

Step-by-step explanation:

Here, we want to find the value of DE

we use the intersecting chord principle

That will be;

CE * ED = AE * BE

we have;

6 * DE = 5 * 12

DE = (5 * 12)/6

DE = 5 * 2

DE = 10

Answers

Answer:

Number of dogs = 6

Number of burgers = 11

Step-by-step explanation:

Number of dogs = x

Number of burgers = 2x - 1

Cost of a dog = $ 1.50

Cost of 'x' dogs = 1.5x

Cost of a burger = $ 2

Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2

                                    = 4x - 2

Total amount collected  = $ 31

1.5x + 4x - 2 = 31 {add 2 to both sides}

        1.5x + 4x = 31 + 2

      1.5x+ 4x  = 33

               5.5x = 33

                    x = 33/5.5

                   x = 6

Number of dogs  = 6

Number of burgers = 2*6 - 1 = 12 - 1 = 11

Geometry please help-
If HI and JI are tangent segments, what is the measure of angle HJI?

Answers

66°

there are 180° in a triangle so do 180-48 to get 132. this gives you the values for both of the other angles together as it is an isosceles triangle. to find the one angle divide this by 2 to get 66°

Answer:

68°

Step-by-step explanation:

We can find this by remembering that tangents meet a circle at a ninety degree angle with the diameter or a radius that touches the point of intersection. By understanding that because these two tangents intersect at a point outside the circle there angle measure is the same so we can use the 180° total in a triangle to find the remaining degrees to be divided into the two measures we need to find. Because 180 - 48 equals 132 we divide this by 2 to get our angle measure of 68 degrees.

Answers

Third table is true with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400 and the second column is labeled money collected (y) with entries 0, 50, 255,2000.

Here, the equation is given as;

y = 5x

Where, x is the number of tickets sold for the school play and y is the amount of money collected for the tickets.

What is linear equation?

A linear equation is an algebraic equation of the form y = mx + b

involving only a constant and a first order (linear) term.

Now, we have the following equation;

y = 5 x

For finding the table that complies with this restriction and also have the corresponding values for x and y.

The third table complies with the given condition and has correct values for the given variables;

⇒ x = 0 then y = 0

⇒ x = 10 then y= 50

⇒ x = 51 then y = 255

⇒ x = 400 then y = 2000

Clearly, Third table is true with 4 rows titled School Play Tickets. The first column is labeled tickets (x) with entries 0, 10, 51, 400 and the second column is labeled money collected (y) with entries 0, 50, 255,2000.

The first one is done and the options for number four are:
w(2w+12)=160
2w^2+12w-260=0
2w^2+12w=260
w^2+6w-130=0

Answers

Answer:

Step-by-step explanation:

Part A

w² + 6w + c = 130 + c

w² + 2(3w) + c = 130 + c

To make left side of the equation a perfect square we will replace c by (3)².

w² + 2(3w) + 3² = 130 + c

[By formula → a² + 2ab + b² = (a + b)²]

w² + 2(3w) + 9 = 130 + 9

Therefore, c = 9 will be the answer.

Part B

From part A,

(w + 3)² = 139

Option (2) and Option (6) are the correct options.

Part C

w + 3 = √139

w = 11.79 - 3

w = 8.79

w ≈ 8.8 inches
