As per the given tax percentage, the sales tax is $3 and the total amount paid by the group including the tip is $47.25

Here we have given that the bill before sale tax and tip is $37.50.

Here we have know that there was a tax of 8%.

And the there was a tip of 18%.

As we all know that the tip is after the tax, then it's not going to affect it, and we can essentially ignore it.

Therefore here the real question here is just what is 8% of $37.50.

Now, here we have to find the percent of something, then first you need to put the percent as a decimal.

Then we get the 8% in decimal form is 0.08 where as 18% as 0.18

Now, we have to multiply the percent in decimal form by the number.

Then we get,

=> 37.50 dollars × 0.08 = 3 dollars.

=> 37.50 dollars × 0.18 = 6.75 dollars.

And the total amount pair is calculated as,

=> 37.50 + 3 + 6.75

=> 47.25

Explanation:

Matrix C has 3 rows and 2 columns. The size or dimensions can be written in shorthand as 3x2.

Matrix D has dimensions 2x1, aka 2 rows and 1 column.

-------------------

Write "3x2" and "2x1" side by side in that exact order.

Notice the inner '2's match up. This is important. We need the inner numbers to match so that matrix multiplication is possible. The outer values '3' and '1' will help form the dimensions of the final answer matrix. The final answer matrix will have dimensions 3x1

Luckily we don't need to compute the value of CD. We just need to use the justification mentioned in the previous paragraphs to conclude that matrix CD is possible.

-------------------

Something like BC is not possible because B is 3x2 and C is 3x2. We don't have a match of inner values this time. We can then rule out the answer choice "BC". The answer choices "DC" and "CB" are ruled out for similar reasoning.

The inverse function is used to find the temperature in Celsius,

the temperature in celsius is  -12.22°C and 32.22°C.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator).

Given expression for temperature calculation

Original function: F =  9/5​C + 32

Inverse function: C = (F − 32)5/9

where C is temp. in Celsius and F is temp. in Fahrenheit,

so when the temperature is given in Fahrenheit we have to use the inverse function formula to calculate the temperature in degree celsius,

because it will be easy to calculate.

temperature = 10°F

C = (F − 32)5/9

C = (10 - 32)5/9

C = -22 x 5/9

C =  -12.22°C

when temperature = 90°F

C = (90 - 32)5/9

C = 32.22°C

Hence the temperature is  -12.22°C and 32.22°C.

The two main types of coordinate systems used in mathematics and physics are Cartesian and Polar Coordinates.

A coordinate system is a system used to identify and locate a point in space. It is the basis for maps, navigation and surveying. Coordinate systems can be two-dimensional or three-dimensional, and can use a variety of units such as latitude, longitude, and feet. Coordinate systems are used in a variety of fields such as engineering, architecture, geology, and navigation. Coordinate systems help to identify and locate points in space and are essential for charting and mapping the physical world.

Cartesian Coordinates, named after the French mathematician and philosopher René Descartes, use a two-dimensional plane to represent points with an x-axis and a y-axis. These coordinates are expressed as ordered pairs (x,y) and represent points in relation to the origin (0,0). This can be used to plot graphs and equations, and is the most commonly used coordinate system.

Polar Coordinates are based on a two-dimensional plane centered on a pole. Points are expressed as ordered pairs (r,θ) where r is the distance from the pole and θ is the angle from the polar axis. This coordinate system is useful for finding distances and angles in a circle. It is used frequently in physics and astronomy.

Every 10 degrees higher in temperature, the slope would be around -3 so draw a line from (40,20) to (80,8) .

How steep a line is defined by its slope. Gradient overflow is a term used to describe a gradient-based mathematical equation (the change in y divided by the change in x). The slope is calculated by dividing the horizontal change (run) between two points by the vertical change (rise) between the same two points. The slope-intercept form of an equation is used to express the equation of a straight line, which is written as y = mx + b. The line's y-intercept is situated where the slope is m, b is b, and (0, b). For instance, the slope and y-intercept of the equation y = 3x - 7 (0, 7).

A perpendicular line is one that is perpendicular or 90 degrees to another line. In order to draw a perpendicular line in Class 7, it is important to understand the formula and calculation associated with it.

The formula associated with perpendicular lines is that the product of the slope of the two lines must be equal to -1. This means that if one line has a slope of m1, then the slope of the perpendicular line must be -1/m1.

In order to calculate the slope of a line, we must use the formula m = (y2-y1)/(x2-x1), where m is the slope, (x1,y1) is the first point, and (x2,y2) is the second point. With this information, we can use the formula to calculate the slope of the line we want to draw a perpendicular line to, and then use the formula m = -1/m1 to calculate the slope of the perpendicular line.

Finally, with the slope of the perpendicular line, we can use the point-slope form of the equation of a line, y-y1=m(x-x1), to plot the equation of the line and draw it on the graph. This formula can be used to draw a perpendicular line in Class 7.

we can find the total volume of material that makes up the ball by subtracting the volume of the hollow space from the volume of the sphere:

V = 20,834 cm^3 - 19,848.44 cm^3

= 985.56 cm^3

Volume is a measure of the amount of space occupied by an object or a substance. It is typically measured in units such as cubic meters (m^3), cubic centimeters (cm^3), or cubic feet (ft^3).

Diameter is a measure of the distance across the widest part of a circular object, such as a circle or a sphere. It is equal to twice the radius of the object and is typically measured in units such as millimeters (mm), centimeters (cm), or inches (in). It is a linear measurement.

To find the total volume of material that makes up the ball, we need to find the volume of the sphere and then subtract the volume of the hollow space in the center.

We can begin by calculating the volume of the sphere using the formula for the volume of a sphere:

V = (4/3) * pi * r^3

Where V is the volume, pi is approximately 3.14, and r is the radius of the sphere.

The outer diameter of the ball is 50 cm, so the radius of the sphere is (50/2) = 25 cm.

Substituting these values into the formula, we get:

V = (4/3) * 3.14 * (25 cm)^3

= (4/3) * 3.14 * 15,625 cm^3

= 20,834 cm^3

Next, we need to find the volume of the hollow space in the center of the ball, which is the same as the volume of a smaller sphere with a radius of (25 cm - 1.25 cm) = 23.75 cm.

So the volume of the hollow space is :

V = (4/3) * pi * (23.75 cm)^3

= (4/3) * 3.14 * (23.75 cm)^3

= 19,848.44 cm^3

Finally, we can find the total volume of material that makes up the ball by subtracting the volume of the hollow space from the volume of the sphere:

V = 20,834 cm^3 - 19,848.44 cm^3

= 985.56 cm^3
