Step-by-step explanation:

Answer:

32,768 ways

Step-by-step explanation:

True/ false questions = 5 ; number of options = 2 (True or false)

Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32

Number of Multiple choice questions = 5

Number of options (A - D) = 4 options

Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024

32 * 1024 = 32,768 ways

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:

63.4 ft²

Step-by-step explanation:

11²(π) /6 = 63.4 ft²

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:

4. 120 cm^2

5. 8x+30

Step-by-step explanation:

Answer:

120 cm^2

8x+30

Step-by-step explanation:

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

    + 12          + 12

8x         =   8x

x         =        1

Step-by-step explanation:

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]

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
