A 18 -inch laptop has a screen that is 7 inches tall. How wide is the screen?
Answers
We are given:
Diagonal Length of the screen = 18 inches
Length of the screen = 7 inches
Width of the screen = x inches
Finding the width:
In the image, we notice a right-angle triangle
So, we can find x using the Pythagoras theorem
Using the Pythagoras theorem:
18² = 7² + x²
x² = 18² - 7²
x² = 324 - 49
x² = 275
x = 16.6
Hence, the screen is 16.6 inches wide
We are to find the width of the laptop
The width of the laptop is 16.6 inches
Diagonal length of the laptop = 18 inches
Length of the laptop = 7 inches
Width of the laptop = x inches
Using Pythagoras theorem
Diagonal ² = length ² + width ²
18² = 7² + x²
x² = 18² - 7²
x² = 324 - 49
x² = 275
find the square root of both sides
x = √275
x = 16.58
Approximately,
x = 16.6 inches

If the ratio of the length of a rectangle to its width is
9/4 and it’s length is 18 cm, what is the width of the rectangle?
Answers
9514 1404 393
Answer:
8 cm
Step-by-step explanation:
It is convenient to write the proportion with the unknown (width) on top:
width/length = 4/9 = w/(18 cm)
Multiplying by 18 cm gives ...
w = (18 cm)(4/9) = 8 cm
The width of the rectangle is 8 cm.

Find the slope between the points. �. (5, −3) (7, 4)
Answers
Answer: slope is [tex]\frac{7}{2}[/tex] or 3.5
Step-by-step explanation:
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{4-(-3)}{7-5}[/tex] = [tex]\frac{7}{2}[/tex]
Answer:
[tex]\boxed {\boxed {\sf m= \frac{7}{2} \ or \ 3.5 }}[/tex]
Step-by-step explanation:
The slope formula is the change in y over the change in x.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We are given the points (5, -3) and (7,4). Therefore,
[tex]x_1=5 \\y_1= -3\\x_2=7 \\y_2=4[/tex]
Substitute the values into the formula.
[tex]m=\frac{4--3}{7-5}[/tex]
Solve the numerator.
4 - -3 = 4+3 = 7[tex]m=\frac{7}{7-5}[/tex]
Solve the denominator
7-5=2[tex]m=\frac{7}{2}[/tex]
[tex]m=3.5[/tex]
The slope between the points is 7/2 or 3.5

Round 4,287,965 to the nearest thousand
Answers
Answer:
It is 4,288,000.
Step-by-step explanation:
To round to the nearest thousand, you need to find the thousands place. In the thousands place there is a "7". Okay, we've found it, so the next step is rounding.
To round, there is a handing phrase that we can use to know whether we should round the place up or down. It is "4 or less, let it rest. 5 or more, add 1 more." We need to apply this phrase to the number behind the place we need to round (so apply it to the place behind the thousands place).
When we look behind the thousands place, we see there is a 9. Apply the rule to that. Since 9 is above 5 and not less than 4, we need to add one more to the thousands place.
That means after we round, the 7 turns into a 8. That's how you get 4,288,000.
Hope this makes sense <3

since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B

A 15 meter long cylinder with a diameter of 7 meters has a square prism with a base length of 4 meters hole going all the way through the center of it as shown in the diagram (not to scale). Find the volume of the composite shape rounding to the nearest cubic meter.
Answers
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.
