Answer:

<h2>30 square meters of carpet</h2>

Step-by-step explanation:

A = 6m x 4.2m + 3.2m x 1.5m

A = 25.2 square m + 4.8 square m

A = 30 square m of carpet

Write the equation of a line perpendicular to 5x – 4y = - 3 that passes through the point (-5,2).
kolezko [41]

Answer: 5y + 4x = - 10

Step-by-step explanation:

Two lines are said to be perpendicular if the product of their gradients = -1.

If the gradient of the first line is m_{1} and the gradient of the second line is m_{2} , if the lines are perpendicular, them

m_{1} x m_{2} = -1 , that is

m_{1} = \frac{-1}{m_{2} }

The equation of the line given is 5x - 4y = -3 , we need to write this equation in slope - intercept form in order to find the slope.

The equation in slope -intercept form is given as :

y =mx + c , where m is the slope and c is the y - intercept.

Writing the equation in this form , we have

5x - 4y = + 3

4y = 5x -+3

y = 5x/4 + 3/4

comparing with the equation y = mx + c , then m_{1} = 5/4

Which means that m_{2} = -4/5 and the line passes through the point ( -5 , 2 ).

Using the equation of line in slope - point form  to find the equation of the line;

y - y_{1} = m ( x -  y_{1} )

y - 2 = -4/5 ( x +5)

5(y - 2 ) = -4 ( x + 5 )

5y - 10 = -4x - 20

5y + 4x = - 10

In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig
horrorfan [7]

Answer:

  (b)  24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

  LH males = 4 × LH females = 4x

  RH females = 3 × RH males = 3y

  LH males + RH males = 204 = 4x +y

  RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

  (x, y) = (24, 108)

There are 24 left-handed females.

__

<em>Additional comment</em>

Other numbers involved here are ...

  y = 108 . . . . right-handed males

  204-108 = 96 . . . . left-handed males (=4×24)

  348-24 = 324 . . . . right-handed females (=3×108)

__

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

  3(204 -4x) +x = 348   ⇒   -11x = -264   ⇒   x = 24
