Answer:

150 ft

Step-by-step explanation:

The diagram shown gives us a picture of two similar right triangle.

The height of the man is similar to the height of the platform.

To find the height of the platform, multiply the height of the man by the scale factor.

Scale factor = the ratio of any corresponding sides of two similar triangles.

Scale factor = 100 ft ÷ 4 ft = 25

Height of man = 6ft

Therefore, height of platform = 6 ft × 25 = 150 ft

Step-by-step explanation:

Given:

 63 – 4 = 8 (2+1/4s) ; Solve for: "s" ;

Note: Rewrite the equation:

↔  8 (2+1/4s) = 63 - 4 ;   (commutative property);

Start with the "right-hand side" of the equation:

  " 63 − 4 " ;  which equals:  " 59. "

___________________________

Rewrite the equation:

___________________________

  →   8 (2 + 1/4s)  =  59 ;

Now, let us examine the "left-hand side" of the equation:

     " 8 (2 + 1/4s) " ;

Note the "distributive property" of multiplication:

           a(b + c) = ab + ac ;

As such:

       " 8 (2 + 1/4s) " ;

                     =  (8×2)  + (8× 1/4s) ;

                     =  16 + 8/4s ;

                      = 16 + 2s ;

Now, rewrite the equation:

                       16 + 2s = 59  ;  Subtract "16" from each side of the equation:

          16 + 2s − 16 = 59 − 16 ;

to get:   2s  = 43 ;

Now, divide each side of the equation by "2" ;  

 to isolate "s" on one side of the equation; & to solve for "s" ;

             2s / 2 =  43 / 2 ;

 to get:

              s =  21. 5 ;  

                  or;  write as " [tex]21 \frac{1}{2}[/tex]  " .

x=-1

Answer:

Step-by-step explanation:

Since the 2 horizontal lines are parallel,

angle 1 and 3 are corresponding angles and hence equal

So, angle 1  = angle 3

20x + 60 = 30x + 20

10x = 40

x = 4

Now, finding angle 1

Angle 1 = 20x + 60

Angle 1 = 20 (4) + 60

Angle 1 = 140 degrees

Answer:

0.275 thats the answer no cap

Step-by-step explanation:

The decimal form of the given fraction is 0.275 lb.

Given that, a bowl weighs 11/40 lb.

We need to express the given fraction in decimals.

When a number is present in a fraction form i.e., p/q, we use the long division method to convert it into a decimal form. In such a case we divide the numerator by the denominator. Let us understand the steps involved in fraction to decimal conversion by the long division method with the help of an example.

Now, the fraction 11/40 can be written in decimal as 11/40=0.275 lb

Therefore, the decimal form of the given fraction is 0.275 lb.

Answer:

  (a) 0.65

  (b) 3/7

  (c) 6/13

Step-by-step explanation:

(a) P(C') = 1 - p(5) -p(6) = 1 - 0.15 - 0.2

  P(C') = 0.65

__

(b) P(B|C) = P(BC)/P(C) = P(5)/(P(5)+P(6)) = 0.15/(0.15 +0.2)

  P(B|C) = 3/7

__

(c) P(B'|C') = P(B'C')/P(C') = (P(1) +P(2))/0.65 = (0.15+0.15)/0.65

  P(B'|C') = 6/13

Answer:

y = 7/2x -11/2

Step-by-step explanation:

7x-2y=11

Subtract 7x from each side

7x-2y -7x = -7x+11

-2y = -7x+11

Divide each side by -2

-2y/-2 = -7x/-2 +11/-2

y = 7/2x -11/2

Answer:

y = 7/2x - 11/2

Step-by-step explanation:

7x - 2y = 11

Subtract 7y to both sides

-2y = 11 - 7x

Divide -2 to both sides

y = 11/-2 - 7/-2x

Answer:

4 and 9

Step-by-step explanation:

let their ages be x and x - 5, then in 4 years their ages will be

x + 4 and x - 5 + 4 = x - 1 , and the product is 104, thus

(x + 4)(x - 1) = 104 ← expand factors on left using FOIL

x² + 3x - 4 = 104 ( subtract 104 from both sides )

x² + 3x - 108 = 0 ← in standard form

(x + 12)(x - 9) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 12 = 0 ⇒ x = - 12

x - 9 = 0 ⇒ x = 9

However, x > 0 ⇒ x = 9

Thus

Their present ages are 9 and 9 - 5 = 4

The area of the triangle QRS vertices have coordinates as (-1,2), (1,-4) and (-2,-2) is given by: Option: 7 sq. units.

Suppose the vertices of the considered triangle ABC are on [tex]A(A_x,A_y), B(B_x,B_y), C(C_x,C_y)[/tex], then, the area of the triangle is given by:

[tex]Area = \dfrac{|A_x(B_y-C_y) + B_x(C_y-A_y) + C_x(A_y-B_y)|}{2}[/tex]

For this case, we're specified that:

Coordinates of the vertices of the triangle QRS are:

(-1,2), (1,-4) and (-2,-2)

Thus, its area is evaluated as:

[tex]Area = \dfrac{|-1(-4-(-2)) + 1(-2-2) + (-2)(2-(-4))|}{2} = \dfrac{|2-4-12|}{2}\\\\Area = \dfrac{14}{2} = 7 \: \rm unit^2[/tex]

Answer:

20

Step-by-step explanation:

The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. You can see that they have some of the same factors, but the greatest they share is 20

The greatest common factor of 80 and 20 is 20.

In Mathematics, factors can be defined as the fundamental building blocks of a number. This ultimately implies that, factors simply refers to numbers which can be multiplied together to get another number.

The factors of 20 include the following: 1, 2, 4, 5, 10, and 20.

The factors of 80 include the following: 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80.

By critically observing the factors above, we can logically deduce that the greatest common factor of 80 and 20 is equal to 20.

Answer:

  20. y = 1/3x +4

  21. y -6 = -1/4(x -3)

  22. 3x +2y = 8

Step-by-step explanation:

Different forms of the equation of a line can be useful for these different forms of the problem of finding the equation.

20. Given the slope and y-intercept, the slope-intercept form is useful.

  y = mx + b

  y = 1/3x + 4

__

21. Given a slope and a point, the point-slope form of the equation is useful.

  y -k = m(x -h)   . . . .    line with slope m through point (h, k)

  y -6 = -1/4(x -3)

__

22. Given 2 points, the 2-point form of the equation of a line is useful.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (4 -(-2))/(0 -4)(x -4) -2

  y = -6/4(x -4) -2

  y = -3/2x +6 -2

  3x +2y = 8 . . . . . . add 3/2x and multiply by 2 (standard form)

Additional comment

The question asks for "an equation", not "the equation", so we assume that any form is suitable. You may find that your grader will only accept a particular form (usually, point-slope form), so you may have to manipulate these into that form to satisfy your grader.
