Answer:

therefore, the width of the rectangle is 10m and length is 20m.

Step-by-step explanation:

Let n represent width

Let n represent width #2

let 2n represent length

let 2n represent length #2

n+n+2n+2n=60

6n=60

n=60/6

n=10

width=10

length= 2n

= 2*10

=20

Let x represent the width of the rectangle.
We know 2x=length
Perimeter of a rectangle is 2(length)+2(width)
So we can make an equation for the perimeter of this particular rectangle.
2(2x)+2(x)=60
4x+2x=60
6x=60
x=10.
Since the width is equal to x, we know that the width of this rectangle is 10 m.
And, the length is twice of the width.
10*2=20
Therefore, the length of the rectangle is 20 meters.

A chemical flows into a storage tank at a rate of (180+3t) liters per minute, where t is the time in minutes and 0<=t<=60
Yuliya22 [10]

Answer:

The amount of the chemical flows into the tank during the firs 20 minutes is 4200 liters.

Step-by-step explanation:

Consider the provided information.

A chemical flows into a storage tank at a rate of (180+3t) liters per minute,

Let c(t) is the amount of chemical in the take at <em>t </em>time.

Now find the rate of change of chemical flow during the first 20 minutes.

\int\limits^{20}_{0} {c'(t)} \, dt =\int\limits^{20}_0 {(180+3t)} \, dt

\int\limits^{20}_{0} {c'(t)} \, dt =\left[180t+\dfrac{3}{2}t^2\right]^{20}_0

\int\limits^{20}_{0} {c'(t)} \, dt =3600+600

\int\limits^{20}_{0} {c'(t)} \, dt =4200

So, the amount of the chemical flows into the tank during the firs 20 minutes is 4200 liters.

Complete the point-slope equation of the line through ( − 5 , 4 ) (−5,4)left parenthesis, minus, 5, comma, 4, right parenthesis
Tanzania [10]

The point slope form of equation through given points is:

y-6=\frac{1}{3}(x-1)

Step-by-step explanation:

Given points are:

(x1,y1) = (-5,4)

(x2,y2) = ((1,6)

First of all we have to find the slope of line

So,

m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{6-4}{1+5}\\=\frac{2}{6}\\=\frac{1}{3}

Point-slope form is given by:

y-y_1=m(x-x_1)

Putting m=1/3

y-y_1=\frac{1}{3}(x-x_1)

Putting (1,6) in the equation

y-6=\frac{1}{3}(x-1)

The point slope form of equation through given points is:

y-6=\frac{1}{3}(x-1)

Quadrilateral ABCD is a parallelogram with diagonals that intersect at point E. If AD=4w-5 DE=4 BE=x/2 BC=7w-17 solve for w.
Alex777 [14]

Answer:

B. w = 4

Step-by-step explanation:

As we know, in a parallelogram length of opposite sides are equal.

so, AD = BC

⇒ 4w - 5 = 7w - 17

⇒ 12 = 3w

⇒ w = 4
