What is the measure of angle DEG on circle O

Answer:

1)X+4=2x-17+10

X. =2x-7-4

11=X

DF=11+4

=15

2)FH~

11x+71=12x+32

12x-11x =71-32

X=39

FH=(11×39)+71+(12×39)+32

=1000

3)57+39+8x-12=180

8x+84-84=180-84

8x=96

X=12

4)11x+2=68

11x=66

X=6

5)114+X+37+X=139

2x+151. -151=139-151

X=-6

Answer:

1. x=11

2. x=39

3. x= 12

4. x=6

5. x=-6

Step-by-step explanation:

1. x+4= 10+2x-17

FG=GH

x+4=2x-7

11=x

2. 11x+71=12x+32

subtract from both sides

39=x

3. All angles of a triangle add to 180.

39+57+(8x-12)=180

96+(8x-12)=180

8x-12=84

8x=72

divide both sides by 8

x=9

4. Vertical angles are equal

68=11x+2

66=11x

divide

6=x

5. (114+x)+(37+x)=139

Add like terms

151+2x=139

subtract

2x=-12

x=-6

Answer:

Step-by-step explanation:

basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below

Answer:

Step-by-step explanation:

Fig 1

<f=180-2×30=180-60=120

<D and <E are base angle of isosceles triangle.

Fig 2

AB=AC=BC=8

All the side of equilateral are equal and all interior angle also equal.

Answer:

Step-by-step explanation:

a) ΔFED is isosceles triangle. EF = ED

∠F = ∠D =x   {Angles opposite to equal sides are equal}

∠F + ∠E + ∠D = 180  {Angle sum property }

x  +x + 30 = 180

  2x + 30  = 180

           2x = 180 -30

           2x = 150

             x = 150/2

             x = 75

∠F = 75

b) All the angles are equal. So, it is an equilateral triangle. In equilateral triangle all sides are equal.

So, AB = 8

Based on the information, the value of the piano after 16 years is $140.74.

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Using this formula to find the value of the piano, v, after t years.

CP = Principal(1-rate)[tex]^t[/tex]

Where:

Principal=$5,000

Rate=20%

Number of year = 16 years

Let plug in the formula;

=5,000(1-0.20)^16

=5,000(.80)^16

=$140.737

= $140.74 (Approximately)

Hence, the value of the piano after 16 years is; $140.74.

Answer:

0.0970

Step-by-step explanation:

Red marbles, R= 5

White, W = 9

Blue, B = 7

Total = (5 + 9 + 7) = 21

Selecting 3 marbles without replacement :

Probability that all marbles are the same

P(RRR) or P(BBB) or P(WWW)

(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)

0.0075187 + 0.0263157 + 0.0631578

= 0.0969922

= 0.0970

Answer:

Number of marbles with Williams at the starting = 192

Step-by-step explanation:

Let total number of marbles with Williams = m

He lost marbles = 25% of the total number

                           = [tex]\frac{25}{100}\times m[/tex]

                           = [tex]\frac{m}{4}[/tex]

Remaining marbles with Williams = m - [tex]\frac{m}{4}[/tex]

                                                        = [tex]\frac{3m}{4}[/tex]

He gave marbles to his brother = [tex]\frac{1}{6}[/tex]th of the remaining marbles

                                                    = [tex]\frac{1}{6}\times \frac{3m}{4}[/tex]

                                                    = [tex]\frac{m}{8}[/tex]

Remaining marbles after giving marbles to his brother = 120

Therefore, [tex]\frac{3m}{4}-\frac{m}{8}=120[/tex]

[tex]\frac{6m}{8}-\frac{m}{8}=120[/tex]

[tex]\frac{5m}{8}=120[/tex]

m = [tex]\frac{120\times 8}{5}[/tex]

m = 192

Number of marbles with Williams at the starting = 192

First, flip the equation around.

3/5=4m

4m=3/5

Now simplify by dividing 4 from both sides.

4m=3/5

/4    /4

m=0.15 or 3/20

Answer: y+2x=15

Step-by-step explanation:

Given

Two points A and B are (4,7) and (6,3) respectively

Using two-point form

[tex]\Rightarrow \dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Putting values

[tex]\Rightarrow \dfrac{y-7}{x-4}=\dfrac{3-7}{6-4}\\\\\Rightarrow \dfrac{y-7}{x-4}=\dfrac{-4}{2}=-2\\\\\Rightarrow y-7=-2x+8\\\\\Rightarrow y+2x=15[/tex]

Simplifying

2(4x + -6) = 8x + -12

Reorder the terms:

2(-6 + 4x) = 8x + -12

(-6 * 2 + 4x * 2) = 8x + -12

(-12 + 8x) = 8x + -12

Reorder the terms:

-12 + 8x = -12 + 8x

Add '12' to each side of the equation.

-12 + 12 + 8x = -12 + 12 + 8x

Combine like terms: -12 + 12 = 0

0 + 8x = -12 + 12 + 8x

8x = -12 + 12 + 8x

Combine like terms: -12 + 12 = 0

8x = 0 + 8x

8x = 8x

Add '-8x' to each side of the equation.

8x + -8x = 8x + -8x

Combine like terms: 8x + -8x = 0

0 = 8x + -8x

Combine like terms: 8x + -8x = 0

0 = 0

Solving

0 = 0

Answer:

X = 1

Step-by-step explanation:

2(4x - 6) = 8x - 12

(8x - 12) = 8x - 12

8x         =   8x

x         =        1

Answer:

Step One: Divide both sides by 2

Step Two: Add 3 to both sides

Step Three: Multiply both sides by 1/6

Step-by-step explanation:

For step one, we can see that half of 12 is 6, half of 6 is 3 and half of 10 is 5.

For step two, we add 3 to the left to cancel out the -3 and add 3 to the left to make 8.

By process of elimination, we can see that C matches up to step 3.
