Dominic is a server at a restaurant. Each dish at the restaurant costs $8. A sales tax of 8% is charged. The total bill amount includes the sales tax of the meal. Dominic earns tips left by customers. The amount of money tipped can be represented by a percentage of the total bill. Order the tip amounts from least to greatest tip, in dollars. 4 dishes 20% tip 6 dishes 14% tip 7 dishes 11% tip
Answer: To find the tip amount in dollars for each order, you need to multiply the total bill amount by the tip percentage.
For the first order of 4 dishes, the total bill amount is $8 per dish * 4 dishes = $<<8*4=32>>32.
The tip amount is $32 * 20% = $6.40.
For the second order of 6 dishes, the total bill amount is $8 per dish * 6 dishes = $<<8*6=48>>48.
The tip amount is $48 * 14% = $6.72.
For the third order of 7 dishes, the total bill amount is $8 per dish * 7 dishes = $<<8*7=56>>56.
The tip amount is $56 * 11% = $6.16.
So, the tip amounts from least to greatest are $6.16, $6.40, and $6.72.

Patrick borrows $1400 from a bank with 10% simple interest each year. How much will patrick need to pay back in total in 2 years?.
Amount Patrick has to pay back is $ 1680 and the simple interest is $ 280.
What is Simple Interest?
Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) 100
Given data ,
Let the principal amount be = A
The value of A = $ 1400
Let the rate of interest be = r
The value of r = 10 %
Let the number of years = T
The value of T = 2 years
Now , the simple interest is calculated by the formula
Simple Interest = ( Principal Amount x Rate x Time Period ) 100
Substituting the values in the equation , we get
Simple Interest = ( 1400 x 10 x 2 ) / 100
Simple Interest = 14 x 20
Simple Interest = $ 280
Therefore , the simple interest in 2 years is $ 280
And , the total amount Patrick has to give back to the bank is given by the formula
Amount in 2 years = Principal + Interest
Amount in 2 years = 1400 + 280
Amount in 2 years = $ 1680
Therefore , the amount in 2 years is $ 1680
Hence , Amount Patrick has to pay back is $ 1680 and the simple interest is $ 280

Sarah has a solid wooden cube with a length of centimeter. From each of its 8 corners, she cuts out a smaller cube with a length of centimeter. What is the volume of the block after cutting out the smaller cubes?.
Therefore ,the volume of the block after cutting out the smaller cubes is (8/25 cm^2)
What is volume ?Any three-dimensional solid's volume is just the amount of space it takes up. A cube, cuboid, cone, cylinder, or sphere can be one of these solids.
Volumes vary depending on the shape. We have examined different three-dimensional objects and shapes in geometry, including cubes, cuboids, cylinders, cones, and more. We will learn how to calculate the volume for each of these shapes.
Here,
volume = (8/25 cm2) represents the block's volume after the smaller cubes have been removed.
First, we must determine the volume of a cube with four or five centimeter sides, which is:
V = (4/5 cm)^2 = (16/25 cm^2)
The volume of each of the eight smaller cubes that was removed must now be subtracted.
v = (1/5 cm)^2 = (1/25 cm^2)
After the smaller cubes are removed, the block's volume is:
V - 8v = (16/25 cm^2) - 8*(1/25 cm^2) = (8/25 cm^2)
Therefore ,the volume of the block after cutting out the smaller cubes is (8/25 cm^2)

A cylindrical vase with a curved surface area of 6.79 square metres will cost Rs. 8.14 to paint.
What is curved surface area?The area with just curved surfaces, leaving the circular top and base, is referred to as the curved surface area. Curved surface area is the amount of space left over after subtracting the cylinder's total circular area. The formula for curved surface area is 2 * pi * r * h.
Here,
We have to calculate the curved surface area of glass in which the flower basket is placed.
Glass is cylindrical,
Height of cylinder = 180cm = 1.8m
Radius of cylinder = 60cm = 0.6m
The curved surface area of the cylinder = 2πrh
The curved surface area of the cylinder = 2*22/7*0.6*1.8
The curved surface area of the cylinder = 6.78584 m²
Cost of painting the glass per m² = Rs. 1.2

The age of Nachelle would be 5 years and the age of Julian would be 7 years.
What is a quadratic equation?
A quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Let's suppose the age of Nachelle is 'x' years then Julian's age would be 'x+2'.
x² + [2(x + 2)]² = 139
x² + 4x² + 8x + 16 = 139
5x² + 8x - 123 = 0
Simplifying this, we get
x = 4.22 and x = -5.82
Age cannot be a negative number so
x ≈ 5.
x + 2 = 7 years

A Formula for the Surface area of the cube is 6a².
A cube is a three-dimensional solid with six square faces, facets, or sides, three of which meet at each vertex in geometry. It looks like a hexagon from the corner, and its net usually looks like a cross. One of the five Platonic solids, the cube is the only regular hexahedron.
The sum of the areas on each face of the cube that covers it is the cube's surface area. The formula for surface area is six times the cube's length divided by the square of that number. It is denoted by 6a², where a is the cube's side length. It basically refers to the entire surface area.
area of one face = a² [By area of square formula]

Given,
Here we need to find the relationship between a 90% confidence interval around a mean and a 95% confidence interval around a mean.
According to the given question, the given confidence interval values are 90% and 95 %.
When we convert this percentage value into decimal, then we get the value as,
90% = 0.9
95% = 0.95
Here a 95 percent confidence interval, you have a 5 percent chance of being wrong.
And with a 90 percent confidence interval, you have a 10 percent chance of being wrong.
Therefore, 90 percent confidence interval would be wider than a 95 percent confidence interval.

The equivalent ratio of yellow cars to purple cars in the form n:1 is 1.54:1.
What is Ratio?A ratio is a mathematical comparison between two or more quantities or values. It expresses the relative sizes or amounts of different quantities and is typically represented in the form of a fraction or a colon (:).
The greatest common divisor (GCD) of 97 and 63 is 1, which means they have no common factors other than 1.
Therefore, we can write the ratio of yellow cars to purple cars as: 97:63
Since we need to write it in the form of n:1, we can divide both sides of the ratio by 63 (the smaller number in the ratio):
= 97/63 : 63/63
= 97/63 : 1
= 1.54 : 1
So, the equivalent ratio of yellow cars to purple cars in the form n:1 is 1.54:1.

Indicate whether the measures 4. 35, 5. 8, and 7. 25 can be the side lengths of a triangle. If they can, classify the triangle. PLEASE HELP!!
yes; right
yes; obtuse
yes; acute
no
Classification of given triangle is right angle triangle.
Let's suppose a, b and c are the sides of a triangle.
then we know that sum of 2 sides is always greater than third side.
a + b>c
b + c>a
c + a>b
a = 4.35, b = 5.8 , c = 7.25
a + b>c 4.35+5.8 = 10.15>7.25
b + c>a 5.8 + 7.25 = 13.05>4.35
c + a>b 7.25+4.35 = 11.60>5.8
So now we can say given side lengths are representing sides of a triangle.
It generalizes the Pythagorean Theorem, which states that for a right-angled triangle square of the hypotenuse is equal to the sum of squares of the base and height of the triangle, which is [tex]c^2 = a^2 + b^2[/tex]
Similarly, It can be observed that
For acute-angled triangle
[tex]c^2 < a^2 + b^2[/tex]
For Obtuse-angled triangle
[tex]c^2 > a^2 + b^2[/tex]
[tex]a^2 + b^2[/tex] = 18.9225 + 33.64 = 52.5625
[tex]c^2[/tex] = 52.5625
clearly we can see that [tex]a^2+b^2 = c^2[/tex]
So given triangle is Right-angled triangle.
