KatRina [158]

Answer: 36 people

Step-by-step explanation:

1. The number of people that aspire to become doctor is:

360 people*0.65=234 people

2.  The number of people that aspire to become police is:

360 people*0.05=18 people

3.  The number of people that aspire to become pilot is:

360 people*0.2=72

4. The sum of people that do not aspire to become entrepreneurs is:

PLEASE HELP

1. y=6

2. y=-12

Step-by-step explanation:

<u>1) If y varies inversely as x, and y=3 as x = -2, find y for the x value of -1.</u>

It is given that

y varies inversely as x

IT will be written as:

y∝1/x

Removing the proportionality symbol

y=k/x

Given

y=3 , x=-2

Putting the values

3=k/-2

k=3*-2 = -6

The equation will be:

y=-6/x

So,

When x=-1

y=\frac{-6}{-1}\\y=6

<u>2) If y varies directly as x, and y=15 as x=-3, find y for the x value of 4</u>

y is directly proportional to x

y∝x

y=kx

Given

y=15, x=-3

Putting the values

y=kx\\15=-3k\\k=\frac{15}{-3}\\k=-5\\The\ equation\ will\ be:\\y=-3xNow,\\x=4\\y=-3(4)\\y=-12

Hence,

1. y=6

2. y=-12

The length of a rectangle is three more than twice the width. Find the width and the length if the perimeter is 84 f
Naddik [55]

\text{Hello! :D}

\boxed{\text{width = 13ft, length = 29ft}}

\text{ Let the width = "w":}\\\\\text{Write an expression to represent the length in terms of "w":}\\\\l = 2w + 3\\\\\text{Formula of a rectangle: } \\\\P = 2l + 2w\\\\\text{Therefore:}\\\\84 = 2(2w + 3) + 2(w)\\\\84 = 4w + 6 + 2w\\\\84 = 6w + 6\\\\\text{Subtract 6 from both sides:}\\\\78 = 6w\\\\\text{Divide both sides by 6:}\\\\78/6 = 6w/6\\\\w = 13ft\\\\\text{Plug this value of "w" into the equations for the length:}\\\\l = 2(13) + 3\\\\l = 26 + 3\\\\l = 29ft
