A rectangular plot of ground is 30 meters longer than it is wide. its area is 10,000 square meters.
dimulka [17.4K]
A = W· L
10,000 = W ( W +30 ) = W² + 30 W
W² + 30 W - 10,000 = 0
W = \frac{-30+ \sqrt{900+40000} }{2}=  \frac{-30+202.24}{2} = 86.12
L = 86.12 + 30 = 116.12
Width of a plot is 86.12 m and lenght is 116.12 m.
Check : A = 116.12 · 86.12 ≈ 10,000

djyliett [7]

Answer:

<em>5.5</em>

Step-by-step explanation:

Given the set of data

5, 4, 2, 1, 1, 2, 10, 2, 3, 5.

The average of the least and the greatest value is known as the midrange

The formula for calculating the midrange is expressed as shown:

Midrange = (Greatest value + Least value)/2

Given

Greatest value = 10

Least value = 1

Midrange = 10+1/2

Midrange = 11/2

Midrange = 5.5

<em>Hence the midrange of the data is 5.5</em>

Which of the following is equivalent to x+1/y divided by g+1/h
Vikki [24]

Answer:

B) x + 1/y times h/g+1

Step-by-step explanation:

We need to divide \frac{x+1}{y} by \frac{g+1}{h} then match with given choices to find the correct equivalent result.

where given choices are:

A) x/y times h/g

B) x + 1/y times h/g+1

C) x+ 1/y divided h/g+1

D) y/x+1 divided g+1/h

So let's divide  \frac{x+1}{y} by \frac{g+1}{h}

\frac{\left(\frac{x+1}{y}\right)}{\left(\frac{g+1}{h}\right)}

we are allowed to flip the bottom fraction and change division sign into multiplication. So we get:

=\left(\frac{x+1}{y}\right)\cdot\left(\frac{h}{g+1}\right)

Hence correct choice is: B) x + 1/y times h/g+1
