A 16 -inch laptop has a screen that is 7 inches tall. How wide is the screen?
Answer:
Approximately 14.4 inches
Step-by-step explanation:
A 16-inch laptop means that a diagonal across the screen is 16 inches.
Imagine that the laptop is a triangle, with 2 sides: the height and the width of screen, and a hypotenuse, the diagonal across the screen (see attached image).
Here, we can use the Pythagorean theorem to find the width.
The relationship is the following
[tex]diagonal^2 = height^2 + width^2[/tex]
We can rearrange this to find the width of the screen:
[tex]diagonal^2 = height^2 + width^2\\diagonal^2 -height^2 = width^2\\width^2 = diagonal^2 -height^2\\width = \sqrt{diagonal^2 - height^2}[/tex]
Let's put in our values for the diagonal and the height:
Diagonal = 16
Height = 7
[tex]width = \sqrt{16^2 - 7^2}\\ width = \sqrt{256 - 49} \\width = \sqrt{207}\\width = 14.3874946[/tex]
As we can see, the width of our laptop is around 14.4 inches.
Answer: approximately 14.4 inches
The width of the laptop screen is x = 14.3inches.
Given that,
A 16 inch laptop has a screen that is 7 inches tall.
We have to determine,
How wide is the screen.
According to the question,
Diagonal length of the laptop = 16 inches
Length of the laptop = 7 inches
Width of the laptop = x inches
By using Pythagoras theorem,
[tex](Diagonal)^2 = (length)^{2} +( width)^{2}\\\\(16)^2 = (7)^2 + x^{2} \\\\x^{2} = 256 - 49\\\\x^{2} = 207\\\\x = \sqrt{207}\\\\x = 14.38 \ inches[/tex]
Hence, The width of the laptop screen is x = 14.3inches.

solve 3(3x - 6) = 18
Steps to solve:
3(3x - 6) = 18
~Distribute left side
9x - 18 = 18
~Add 18 to both sides
9x = 36
~Divide 9 to both sides
x = 4
Best of Luck!
Answer:
x = 4
Step-by-step explanation:
Let's work on isolating (3x - 6). Start by dividing both sides of 3(3x - 6) = 18 by 3, obtaining:
3x - 6 = 6.
Next, add 6 to both sides:
3x = 12
Finally, divide both sides by 3:
x = 4
What is 90.125 written in expanded form? A. 9 × 10 + 1 × 1 + 2 × 1 10 + 5 × 1 100 B. 9 × 1 + 1 × 1 10 + 2 × 1 100 + 5 × 1 1 , 000 C. 9 × 10 + 1 × 1 10 + 2 × 1 100 + 5 × 1 1 , 000 D. 9 × 1 + 1 × 1 100 + 2 × 1 1 , 000 + 5 × 1 10 , 000
Using digit concepts, it is found that, in expanded form:
[tex]90.125 = 9 \times 10^1 + 0 \times 10^0 + 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]
--------------------
Each number can be divided into an integer part and a decimal part. For 90.125, the integer part is 90 and the decimal part is 0.125.In the integer part, starting from the last digit, each is multiplied by the "next" power of 10, thus:[tex]90 = 0 \times 10^{0} + 9 \times 10^{1} = 9 \times 10^{1} + 0 \times 10^{0}[/tex]
For the decimal part, starting from the first decimal digit, the same logic applies, using negative powers of 10 starting at -1, thus:[tex].125 = 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]
Combining the integer and decimal parts, we get that the number in expanded form is:
[tex]90.125 = 9 \times 10^1 + 0 \times 10^0 + 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]

Answer:
a = - 1.1
Step-by-step explanation:
The condition for a single variable function f(x) to be decreasing is f'(x) < 0.
f(x) = 4/x^2 - 6x + 9
Then, differentiating with respect to x on both sides we get,
f(x) = 4(-2)(1/x^3) - 6 < 0
-8/x^3 - 6 < 0
8/x^3 + 6 > 0
{Dividing both sides with - 1 and hence the inequality sign changes}
8/x^3 > -6
8 > - 6x³ {Multiplying both sides with x³}
6x³ > - 8 {Interchanging the sides}
x^3 > -8/6
⇒ x > - 1.1
So, a = - 1.1
Answer:
a = 3
Step-by-step explanation:
The function can be written as ...
f(x) = 4/(x -3)^2
This has a vertical asymptote at x=3 and will be decreasing for all values of x to the right of that -- on the interval (3, ∞).
a = 3

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The average rate of change in TQ) for the interval d = 4 and d = 10 is 0. Which statement must be true?
O The same number of tickets was sold on the fourth day and tenth day.
O No tickets were sold on the fourth day and tenth day.
O Fewer tickets were sold on the fourth day than on the tenth day.
More tickets were sold on the fourth day than on the tenth day.
Answer: The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given: [tex]T(d)[/tex] is a function that relates the number of tickets sold for a movie to the number of days 'd' since the movie was released.
Also, the average rate of change in T(d) for the interval d = 4 and d = 10 is 0.
Since the average rate determines the rate of change in the dependent variable (T(d)) with respect to the independent variable (d).
It means that there is no change from 4th day to 10th day in the number tickets sold.
Hence, the correct option is "The same number of tickets was sold on the fourth day and tenth day."

Answer:
x= 105 also because it's a z angle
y= 180-105
=75
x=z which is 105, because they are alternative angles.
The given angle of 105 and angle z are consecutive interior angles and need to equal 180 degrees.
Z = 180-105 = 75 degrees
Angle z and angle c are vertical angles and are identical so angle x also equals 75 degrees
Angle y and 105 are supplementary angles and when added equal 180
Angle y is 180-105 = 75
X, y and z are all 75 degrees

Find the cardinal number of the set
C = {x|x € N, 30 < x < 56 and x is divisible by 6},
=====================================================
Explanation:
We're given the following
[tex]C = \{ x | x \in \mathbb{N}, \ 30 < x < 56, \ \text{ x is divisible by 6}\}[/tex]
which means that we have a set of natural numbers between 30 and 56, excluding both endpoints, and the set of numbers are also multiples of 6.
So looking at the multiples of 6 that are between 30 and 56 leads us to
{30, 36, 42, 48, 54}
but we cross off 30 as we want x to be larger than that, so we get this updated final list
{36, 42, 48, 54}
There are four items in this final list so the cardinality of the set described is 4. The cardinality is just the number of items in a given set.

Gold mines in northern Nevada produce an average of 3.2 grams of gold per short ton (2,000 pounds) of ore. The value of gold is usually reported in troy ounces (ozt), and a troy ounce is equal to 31.1 grams (g). On average, how many troy ounces of gold are extracted from one short ton of Nevada ore
Answer:
0.1028938
Step-by-step explanation:
Given the following :
Average gold production in Northern Nevada =3.2 grams per short ton (2000 pounds)
Value of gold is measured in Troy ounces (ozt)
1 Troy ounces = 31.1 grams(g)
Number of Troy ounces of gold extracted from one short ton of Nevada ore ; let the number be t:
1 ozt = 31.1 g
t = 3.2 g
Cross multiply :
31.1 × t = 3.2 × 1
31.1t = 3.2
t = 3.2 / 31.1
t = 0.1028938 ozt
Hence, On average, 0.1028938 ozt of gold is extracted from one short ton of Nevada ore
