Answer:

700

55%

Step-by-step explanation:

70% of 1000 is equal to

{70/100)*1000

= 0.70*1000

= 700.

This, 70% of 1000 means 700 out of 1000 said that miniskirts were not appropriate in the workplace.

b. 550 of 1000 respondents said that shorts are unacceptable in the workplace. The percentage is

{550/1000)*100

= 0.55*100

= 55%

Thus 55% of 1000 respondents said that shorts are unacceptable in the workplace.

A line has a slope of 1/4 and passes through the point (4,8). Write the equation of the line in slope intercept form.​
Yuri [45]

Answer:

y = 1/4x +7

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = 1/4 x +b

Substitute the point into the equation

8 = 1/4(4) +b

8 = 1 +b

Subtract 1 from each side

8-1 =b

7 =b

y = 1/4x +7

The width of a rectangle is (x+1) and the length is (x-6). What is the length and width of the rectangle if the area is 30 squar
jolli1 [7]

Answer:

The length of the rectangle (l) = 3 feet

The width of the rectangle (W) =  10 feet

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the width of the rectangle  = (x+1) feet</em>

<em>Given that the length of the rectangle = ( x-6) feet</em>

<em>The area of the rectangle = 30 square feet</em>

<u><em>Step(ii):-</em></u>

We know that the area of the rectangle

                = length ×width

    30   = ( x+1)(x-6)

    30   = x² - 6x + x -6

⇒ x² - 5 x - 6 = 30

⇒ x² - 5 x - 6 - 30 =0

⇒ x² - 5 x - 36 =0

 x² - 9 x +4x - 36 =0

   x (x-9) +4 ( x-9) =0

   ( x+4 ) ( x-9) =0

     ( x+4 ) =0 and  ( x-9) =0

     x =-4 and x =9

<u><em>Step(iii):-</em></u>

we have to choose x =9

     The length of the rectangle (l) =  x-6 = 9-6 =3

      The width of the rectangle (W) =  x+1 =  9 +1 = 10

<u><em>Final answer:-</em></u>

The length of the rectangle (l) = 3 feet

The width of the rectangle (W) =  10 feet
