Answer:

Value of x --> 15°

Step-by-step explanation:

(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.

---> (2x + 60°) + 6x = 180°

     2x + 60° + 6x = 180°

     8x + 60° = 180°

     8x = 180°- 60°

     8x = 120

      x = [tex]\frac{120}{8}[/tex]

Answer:

The average of each day is 6 fishes

Step-by-step explanation:

Given

See attachment for dot plot

Required

Determine the true statement

For day 1, we have:

[tex]Fis hes = 3 + 6 + 6 + 6 + 6 + 3[/tex]

[tex]Fis hes = 30[/tex]

[tex]Participants = 6[/tex]

The mean is:

[tex]Mean = \frac{Fish es}{Participants}[/tex]

[tex]Mean = \frac{30}{6}[/tex]

[tex]Mean = 5[/tex]

For day 2, we have:

[tex]Fis hes = 3 + 3 + 4 + 6 + 7 + 7[/tex]

[tex]Fis hes = 30[/tex]

[tex]Participants = 6[/tex]

The mean is:

[tex]Mean = \frac{Fish es}{Participants}[/tex]

[tex]Mean = \frac{30}{6}[/tex]

[tex]Mean = 5[/tex]

Answer:

[81 is the missing number.]

Step-by-step explanation:

7+x=88

Let us substitute the mixing number as x.

To find a variable we must ISOLATE it.

To isolate in this situation, we must remove the 7.

We must subtract 7 from both sides, to isolate x. like this-

7-7+x=88-7

This results in,

x=81

So this missing number or (x) is equal to 81

Answer:

Step-by-step explanation:

1). From the triangle given in the figure,

   m∠BAD = 26°

   By applying tangent rule in ΔADB,

   tan(∠BAD) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

   tan(26°) = [tex]\frac{BD}{AD}[/tex]

   BD = 21[tan(26°)]

   BD = 10.24

   By applying sine rule in ΔBDC,

   sin(52°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

   sin(52°) = [tex]\frac{10.24}{x}[/tex]

    x = [tex]\frac{10.24}{\text{sin}(52)}[/tex]

    x = 12.99

    x ≈ 13.0 units

2). By applying cosine rule in ΔADB,

    cos(39°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

    cos(39°) = [tex]\frac{BD}{50}[/tex]

    BD = 50cos(39°)

    BD = 38.86

    By applying sine rule in ΔBDC,

    sin(24°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]  

    sin(24°) = [tex]\frac{38.86}{x}[/tex]

               x = [tex]\frac{38.86}{\text{sin(24)}}[/tex]

               x = 95.54

              x ≈ 95.5 units

Answer: [tex]-\dfrac{2\sqrt{14}}{9}[/tex]

Step-by-step explanation:

Given

[tex]\cos a=\dfrac{5}{9}[/tex]

[tex]a[/tex] lies in the fourth quadrant

So, sine must be negative in the fourth quadrant

Using identity [tex]\sin ^2 x+\cos^2 x=1[/tex] to find sine value

[tex]\Rightarrow \sin^2 a=1-\dfrac{5^2}{9^2}[/tex]

[tex]\\\\\Rightarrow \sin^2 a=1-\dfrac{25}{81}\\\\\\\Rightarrow \sin^2 a=\dfrac{56}{81}\\\\\\\Rightarrow \sin a=-\sqrt{\dfrac{56}{81}}\\\\\\\Rightarrow \sin a=-\dfrac{2\sqrt{14}}{9}[/tex]

Answer:

Tn = 3n + 1

Step-by-step explanation:

The given sequence 2,5,8,11,14 is an arithmetic sequence

The nth term of an arithmetic sequence is expressed as;

Tn = a + (n-1)d

a is the first term

d is the common difference

n is the number of terms

Given

a = 2

d = 5-2 = 8-5 = 3

Substitute into the formula

Tn = 2 + (n-1) * 3

Tn = 2 + 3n - 3

Tn = 3n + 1

This gives the term rule for the sequence

The equations representing the lines that are perpendicular to line m are:

B. y = -2/3x +4

E. y+1=-4/6(x+5)

Lines that are perpendicular to each other have slopes that are negative reciprocal of each other.

For example, if a line has a slope of 2, the slope of a line that is perpendicular to it would be, -1/2 (negative reciprocal of 2).

Determine the slope of the given line whose equation is, y + 2 = 3/2(x + 4). Rewrite the equation in slope-intercept form [y = mx + b]:

y + 2 = 3/2x + 6

y = 3/2x + 6 - 2

y = 3/2x + 4

The slope is therefore 3/2.

Negative reciprocal of 3/2 is -2/3.

Examine each of the equations given and see which equation has a slope of -2/3.

A. y = -3/2x +4, the slope is -3/2.

B.  y = -2/3x + 4, the slope is -2/3. (perpendicular)

C.  y = 2/3x +4, the slope is 2/3.

D. y = 3/2x +4, the slope is 3/2.

E. y+1=-4/6(x+5), rewrite in slope-intercept form

y+1=-4/6x + 20/6

y + 1 = -2/3x + 10/3

The slope is -2/3. (perpendicular)

F. y+ 1 = 3/2(x + 5), the slope is 3/2.

Therefore, the equations representing the lines that are perpendicular to line m are:

B. y = -2/3x +4

E. y+1=-4/6(x+5)

The solution is, square root of 225/16  is 15/4.

A square root of a number is a value that, when multiplied by itself, gives the number. In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x.

For example, 4 and −4 are square roots of 16, because 4² = ² = 16.

here, we have,

225/16

=15^2/4^2

so, square root of 225/16

=√15^2/4^2

=15/4

Hence, The solution is, square root of 225/16  is 15/4.

Answer:

Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi

Step-by-step explanation:

The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.
