The length of the rectangle is 3 times its width.

Mathematics
1 answer:
Blizzard [7]3 years ago
4 0

Answer:

Since length is three times, hence it is 6 inches.

let the width be x.

then, length= 3x

perimeter= 16 inches.

perimeter of a rectangle = 2( L+B)

2(3x+x)=16.

3x+x= 16÷2

4x= 8

x= 2

since length=3x

hence, 3×2= 6 inches

Please solve and explain <br><br>4w(w-3)=24<br>​
nadya68 [22]

Step-by-step explanation:

4w (w - 3) = 24

4w^2 - 12w = 24

4w^2 - 12w - 24 = 0

use calculator, EQN if using Casio

the answer will be

w = _____ w = _____

24. The temperature, T, of a given mass of gas varies inversely with its volume, V. The temperature of 500 cm^3 of a certain gas
Alja [10]

None of the given choices is the correct solution. 

The setup of the problem is a correct, if somewhat weird, description
of the ideal gas laws, but the temperature involved in the law is the
ABSOLUTE temperature, NOT the Celsius or Fahrenheit one, or
any other scale where 'zero' is not 'Absolute Zero'.

Zero Celsius is (about) 273 Celsius-size degrees above Absolute Zero. 
So the original temperature of the gas is  (273 + 2.5) = 275.5 Kelvins
(Celsius degrees above absolute zero).  THAT's the temperature that's
going to change in inverse proportion to the volume.
(if the pressure doesn't change)

The volume has been multiplied by  100cm³/500cm³ = 1/5 .

Since the temperature changes inversely, it will be multiplied by  5 .

Final absolute temperature = (5) x (original absolute temperature) =

                                           (5) x (275.5 K) =

                                             1377.5 K .

The final Celsius temperature is  (1377.5 - 273) = <em>1104.5 °C</em>.


"But those are the choices in the assignment !"
Then the person who wrote the question in the assignment is wrong.
None of the choices they gave is correct.

What is the vertex of the graph of y = −1(x − 2)2 + 3
Alona [7]

Vertex: \ (2,3)

<h2>Explanation:</h2>

The vertex form of the equation of a parabola is given by the following form:

f(x)=a(x-h)^2+k \\ \\ Where: \\ \\ a:Leading \ Coefficient \\ \\ (h,k):Vertex \ of \ the \ parabola

In this exercise, we have the following equation:

y=-(x-2)^2+3

From here, we can conclude that:

Leading \ coefficient: \ -1 \\ \\ Vertex: \ (2,3)

Since the leading coefficient is less than zero, the parabola open downward. So, the graph is shown below and the vertex has been indicated.
