The perimeter of a parallelogram is 76 inches and 1 side measures 14 inches of it can be determined what are the lengths in inch
nydimaria [60]

The dimension of the parallelogram ABCD will be 14 inches, 48 inches, 14 inches and 48 inches.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

The perimeter of a parallelogram is 76 inches.0

And one side measure is 14 inches.

Then the rest of the sides will be

We know that opposite sides are prallel and equal.

Let ABCD is a parallelogram.

AB = CD = 14 inches

BC = AD = x

Then the value of x will be

We know

 P = 2(AB + BC)

76 = 2(14 + x)

 x = 48

More about the parallelogram link is given below.

How do you write <br><br> 40/25<br> as a percentage?
rosijanka [135]
<span>What percent of 40 is 25? 
Let x = what percent 
of = multiplication 
is means = 
We now write it in math terms: 
x times 40 = 25 

40x = 25 
Divide both sides by 40 to find x. 
x = 25/40 
x = 0.625 
Change the decimal number 0.625 to a percent. 
x = 62.5%

The altitude of a triangle is increasing at a rate of 1 cm/min while the area of the triangle is increasing at a rate of 2 cm^2/
VARVARA [1.3K]

Answer:

The base is decreasing at 2 cm/min.

Step-by-step explanation:

The area (A) of a triangle is given by:

A = \frac{1}{2}bh   (1)

Where:

b: is the base

h: is the altitude = 10 cm

If we take the derivative of equation (1) as a function of time we have:

\frac{dA}{dt} = \frac{1}{2}(\frac{db}{dt}h + \frac{dh}{dt}b)

We can find the base by solving equation (1) for b:

b = \frac{2A}{h} = \frac{2*120 cm^{2}}{10 cm} = 24 cm

Now, having that dh/dt = 1 cm/min, dA/dt = 2 cm²/min we can find db/dt:

2 cm^{2}/min = \frac{1}{2}(\frac{db}{dt}*10 cm + 1 cm/min*24 cm)

\frac{db}{dt} = \frac{2*2 cm^{2}/min - 1 cm/min*24 cm}{10 cm} = -2 cm/min    

         

Therefore, the base is decreasing at 2 cm/min.

               

I hope it helps you!

One number is 16 more than a second number. The sum of the first number and twice the second number is 139. What is the answer ?
Nezavi [6.7K]
Answer first number  = 57  second number = 41
x= 16 + y
x + 2y = 139

16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41

x= 16+y
x = 16+41
x= 57
