What is a 30-60-90 triangle?In Mathematics and Geometry, a 30-60-90 triangle is also referred to as a special right-angled triangle and it can be defined as a type of right-angled triangle whose angles are in the ratio 1:2:3 and the side lengths are in the ratio 1:√3:2.
This ultimately implies that, the length of the hypotenuse of a 30-60-90 triangle is double (twice) the length of the shorter leg (adjacent side), and the length of the longer leg (opposite side) of a 30-60-90 triangle is √3 times the length of the shorter leg (adjacent side):
Adjacent side = 5/√3
Hypotenuse, x = 2 × 5/√3
Hypotenuse, x = 10/√3.

Penelope goes out to lunch. The bill, before tax and tip, was $16.05. A sales tax of 3% was added on. Penelope tipped 18% on the amount after the sales tax was added. How much tip did she leave? Round to the nearest cent.
Answer:
2.98
Step-by-step explanation:
First find 3% of 16.05 which is 0.48.
Then add 0.48 to 16.05 which is 16.53.
Then multiply .18 by 16.53 which gets you 2.98
Hope it helps
Answer:
To find the amount of the sales tax, we need to multiply the bill amount by the tax rate of 3% or 0.03:
Sales tax = 0.03 x $16.05 = $0.48
To find the total amount of the bill after the sales tax was added, we need to add the bill amount to the sales tax:
Total bill = $16.05 + $0.48 = $16.53
To find the amount of the tip, we need to calculate 18% of the total bill after the sales tax was added:
Tip = 0.18 x $16.53 = $2.98
Rounding to the nearest cent, Penelope left a tip of $2.98.

A manufacturer has 576 square inches of material available to construct the 6 faces of a carton, which will be in the shape of a rectangular prism. To maximize the volume, the carton will have dimensions such that the length and width are each twice the height.
To maximize the volume, of the rectangular prism, the carton should have dimensions of approximately 10.74 inches (length), 10.74 inches (width), and 5.37 inches (height).
What is the dimension required to maximize the volume of the box?Assuming the height of the rectangular prism is h inches.
According to the given information, the length and width of the prism will be twice the height, which means the length is 2h inches and the width is also 2h inches.
The total surface area of the rectangular prism is given by the formula:
Surface Area = 2lw + 2lh + 2wh
Substituting the values, we have:
576 = 2(2h)(2h) + 2(2h)(h) + 2(2h)(h)
576 = 8h² + 4h² + 4h²
576 = 16h² + 4h²
576 = 20²
h² = 576/20
h² = 28.8
h = √28.8
h = 5.37
The height of the prism is approximately 5.37 inches.
The length and width will be twice the height, so the length is approximately 2 * 5.37 = 10.74 inches, and the width is also approximately 2 * 5.37 = 10.74 inches.

Step-by-step explanation:
Mean of x = Σx / n
Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2
Sum of square (SS) :
(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8
Mean of y = Σy / n
Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2
Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8
df = n - 2 = 5 - 2 = 3
Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6
√(Σ(y - ybar)² / df) = √1449.6 = 38.074
Standard Error = √(Σ(y - ybar)² / df) / √SS
Standard Error = 38.074 / √98.8
Standard Error = 3.83

if the numbers 8 and 12 are increased by 25%and 33 1/3 % respectively,what will be the average increament
The average increment is 3.
To find the average increment, we need to calculate the total increment and divide it by the number of values.
Let's calculate the increments for 8 and 12:
For 8 increased by 25%:
Increment = 8 * 0.25 = 2
For 12 increased by 33 1/3%:
Increment = 12 * (1/3) = 4
Now, let's find the average increment:
Total increment = Increment for 8 + Increment for 12 = 2 + 4 = 6
Number of values = 2
Average increment = Total increment / Number of values
= 6 / 2
= 3

Your friend printed a picture of a regular 18-gon. She wants to cut the 18-gon into right triangles. If she divides the figure into 36 right triangles, what are the measures of the non-right angles of each triangle?
The measures of the non-right angles of each triangle are 40 degrees and 50 degrees.
The sum of the interior angles of a regular 18-gon can be found using the formula:
S = (n - 2) × 180 degrees
n is the number of sides of the polygon.
Substituting n = 18 we get:
S = (18 - 2) × 180 degrees
= 2880 degrees
The 18-gon into 36 right triangles need to draw 18 lines from the center of the polygon to its vertices dividing the polygon into 36 congruent sectors each with a central angle of 360 degrees / 18 = 20 degrees.
Each sector is an isosceles triangle with two sides of equal length radiating from the center of the polygon.
The vertex angle of each isosceles triangle is equal to twice the central angle or 40 degrees.
Since the vertex angle of a right triangle is 90 degrees the two non-right angles of each right triangle are 40 degrees and 50 degrees.

9. A tennis ball manufacturer wants to estimate the mean circumference of tennis balls within 0.05 inch.
Assume the population of circumferences is normally distributed. Determine the minimum sample size
required to construct a 95% confidence interval for the population mean. Assume the population
standard deviation is 0.10 inch..
The minimum sample size required to construct a 95% confidence interval for the population mean is 16.
To determine the minimum sample size required to construct a 95% confidence interval for the population mean circumference of tennis balls within 0.05 inch, we need to use the formula for the margin of error:
Margin of error = Z* (σ/√n)
Where Z* is the z-score corresponding to the desired confidence level, σ is the population standard deviation, and n is the sample size.
Since we want a 95% confidence interval, Z* = 1.96 (from a standard normal distribution table).
We are given that σ = 0.10 inch and we want the margin of error to be 0.05 inch. Plugging in the values, we get:
0.05 = 1.96 * (0.10 / √n)
Solving for n, we get:
n = [(1.96 * 0.10) / 0.05]² = 15.36
We can't have a fractional sample size, so we round up to the nearest whole number. Therefore, the minimum sample size required is 16.
This means that the manufacturer needs to randomly select and measure the circumferences of at least 16 tennis balls to estimate the population mean circumference with 95% confidence and a margin of error of 0.05 inch.

Step-by-step explanation:
Input 3 x coordinates into the equation and find the y. 0, 1, and 2 will do.
-5x - 3y = -7
Substitute variable.
-5(0) - 3y = -7
Remove the term multiplied by 0.
-3y = -7
Divide by -3.
y = -7/-3
-a/-b = a/b.
y = 7/3
This makes the coordinate (0, 7/3)
-5x - 3y = -7
Substitute variable.
-5(1) - 3y = -7
Multiply.
-5 - 3y = -7
Add 5 to both sides.
-3y = -2
Divide by -3.
y = -2/-3
-a/-b = a/b.
y = 2/3.
This makes the coordinate (1, 2/3)
-5x - 3y = -7
Substitute variable.
-5(2) - 3y = -7
Multiply.
-10 - 3y = -7
Add 10 to both sides.
-3y = 3
Divide by -3.
y = 3/-3
-a/a = -1.
y = -1.

a number is multiplied by 8 and that product is added to 2. The sum is equal to the product of 2 and 25 . Find the number
Answer:
6
Step-by-step explanation:
So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:
\(8x+2\)
And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:
\(8x+2=50\)
To find the number, we just need to find x. Thus, subtract 2 from both sides:
\(8x=48\)
Divide both sides by 8:
\(x=6\)
And we're done!
So, our original number was 6.
