The width of a rectangle is the length minus 2 units. The area of the rectangle is 48 units. What is the width, in units, of the

ivanzaharov [21]

Answer:

6 units

Step-by-step explanation:

Remember the formula for the area of a rectangle: A = lw

What we know:

A=48

w = l-2

Substitute A for 48 and w for l-2 into the equation

A = lw

48 = l(l-2) Use the distributive property. Multiply over the brackets.

48 = l² - 2l

Rearrange the equation to standard form (0 = ax² + bx + c) to use quadratic formula.

0 = l² - 2l - 48

a = 1 ; b = -2 ; c = -48 State the variables for the quadratic formula

Substitute a, b and c to find the length:

$l = \frac{-b± \sqrt{b^{2}-4ac} }{2a}$

$l = \frac{-(-2)± \sqrt{(-2)^{2}-4(1)(-48)} }{2(1)}$ Simplify

$l = \frac{2± \sqrt{4-(-192)} }{2}$

$l = \frac{2± \sqrt{196} }{2}$

$l = \frac{2± 14 }{2}$

Split the equation at the ± for adding and subtracting. Then decide which answer is correct, or if both of them are possible answers.

$l = \frac{2- 14 }{2}$

$l = \frac{-12 }{2}$

$l = -8$ This is "inadmissable", or impossible because the length can't be a negative value.

$l = \frac{2+ 14 }{2}$

$l = \frac{16 }{2}$

$l = 8$ Length of the rectangle

Use the formula for the area of a rectangle

Substitute the length and area, then isolate "w" for the width

A = lw

48 = (8)w

48/8 = w

w = 6

Therefore the length of the rectangle is 6 units.

A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va

Setler79 [48]

Answer:

A) $\frac{x}{8}$ gallons

B) Distance between Town A and Town B is $48y$ miles

Step-by-step explanation:

We know, number of gallons = $\frac{DistanceTravelled}{MilesPerGallon}$

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = $\frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}$

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

$NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y$

A cone with a radius of 12 cm and a height of 12 cm has the same volume as a cylinder with a radius of 8 cm. What is the height

Dmitry [639]

First, substitute the given radius and given height of the cone into the formula for the volume of a cone.

Volume of a cone: (1/3) pi r^2 h
In this case, the cone volume is (1/3) pi (12 cm)^2 (12 cm) = 576 cm^3

Vol. of a rt. cylinder: pi r^2 h
In this case, the vol. of the rt. cyl. is pi (8 cm)^2 h.

The two different shapes have the same volume. Therefore, set the two formulas (above) equal to each other:

576 pi cm^3 = pi (8cm)^2 h. This becomes

576 pi cm^3 = pi (64 cm^2) h. "pi" cancels out, leaving us with

576 cm^3
------------- = h. This is the height of the cylinder, in cm.
64 cm^2
