Answer: 6931

Step-by-step explanation:

79% of all students are taking math this semesters.  So there is an additional 21% of students not taking math.

5476/x = 79/100

cross multiply and divide to get the total number of students.

5476 x 100 = 547600

547600 divided by 79 = 6931  

check 5476 divided by 6931 = 79%  

Further proof of correct answer:

21% of 6931 = 1455

1455 + 5476 equals 6931, so the answer calculated is correct.

Answer

Area of the figure = 105.12 ft²

Explanation

The figure shown is a combination of a rectangle with length 10 ft. and width 8 ft., with a semicircle that has diameter 8 ft., which translates to a radius of 4 ft.

The area of the figure = (Area of the rectangle) + (Area of the semicircle)

Area of rectangle = L × W

L = Length = 10 ft.

W = Width = 8 ft.

Area of the rectangle = 10 × 8 = 80 ft²

Area of semicircle = Half of the area of a circle = ½ × πR²

π = pi = 3.14 (According to the question)

R = Radius of the semicircle = 4 ft.

Area of semicircle = ½ × 3.14 × 4² = 25.12 ft²

Area of the figure = 80 + 25.12 = 105.12 ft²

The amount paralegal earned from the job is 1860 dollars.

The amount allocated for savings is 1116 dollars.

Paralegal bills the law firm for 15.5 hours of work at a rate of $120 per hour.

Therefore, the law firm have to pay paralegal 120 dollars for every hour worked.

Therefore,

the amount earned by paralegal = 15.5 × 120

the amount earned by paralegal = 1860 dollars

Paralegal splits her earnings between utilities and savings in a ratio of 2 ∶ 3.

Therefore, let's find the amount of money allocated for her savings.

amount allocated for savings = 3 / 5 × 1860

Ben must bowl 130 in his third game so that the average will be of at least 160.

Given that, Ben bowled 157 and 193 in his first two games. So, we have to calculate the average of his third bowl to have an average of at least 160.

Let the average of third bowl be x.

The average is known as the arithmetic mean which is the sum of all numbers in a collection, divided by the count of the numbers present in the collection. In other words, the average is the ratio of the sum of all given observations to the total number of observations. Hence, the average formula is:

Average = Sum of the Observations/Number of Observations

160 = 157+193+x/3

⇒ 160×3 = 157+193+x

⇒ 480 = 350+x

⇒ 480-350 = x

⇒  130 = x

Therefore, Ben must bowl 130 in his third game so that the average will be of at least 160.

Hence, 130 is the required answer.

If a car consumes 110 liters of fuel with in a distance of 250 km, then the rate of fuel consumption is 2.5 km/liter

The distance travelled by the car with 110 liters of fuel = 250km

To find the rate of fuel consumption we have to apply the unitary method

The distance travelled by the car with 1 liters of fuel = The distance travelled by the car with 110 liters of fuel /110

Substitute the values in the equation

The distance travelled by the car with 1 liters of fuel = 250/110

= 2.5 km

So a car consumes 1 liters of fuel to cover 2.5 km

The rate of fuel consumption = 2.5 km/liter

Hence, if a car consumes 110 liters of fuel with in a distance of 250 km, then the rate of fuel consumption is 2.5 km/liter

Step-by-step explanation:

The inequality that represents having enough money to buy the gaming system is x ≥ 35.

The mathematical expression that represents the sentence " you charge $10 per dog" is x = 10 where x is the number of dogs.

x ≥ 35 means that the minimum number of dogs to wash is 35 to make $500.

It is a statement of an ordered relationship

- greater than,

- greater than or equal to,

- less than,

- less than or equal to between two numbers or algebraic expressions.

We have,

The cost of the gaming system = $500

Amount already saved = $150

Charges per dog = $10

The inequality that represents having enough money to buy the gaming system:

150 + 10x ≥ 500

10x ≥ 500 - 150

10x ≥ 350

x ≥ 35   where x is the number of dogs.

The mathematical expression that represents the sentence " you charge $10 per dog ":

x = 10 where x is the number of dogs.

x ≥ 35 means that the minimum number of dogs to wash is 35 to make $500.

Thus,

The inequality that represents having enough money to buy the gaming system is x ≥ 35.

The equation of the line is y = -1x + 3.

Parallel lines are any two or more lines that all lie in the same plane and never cross one another. They are equally spaced apart and have the same incline. In this essay, let's study more about parallel lines. No matter how far we extend a parallel line, it will never meet another parallel line.

The slope so rewrite the equation for the line as y = -x + 1.

The equation in “y = mx + b” form, the slope is always the number m in front of x.

The slope is -1.

First, by using “y = mx + b” form,

we know m is -1 so only need b.

To get b, plug in the (x, y) coordinates for the point (-1, 4)

(4) = -1×(-1) + b.

The y-coordinate 4 on the left side, and the x number -1 on the right.

b = 3.

Therefore, the equation of the line is y = -1x + 3.

Step-by-step explanation:

The function can be written in point-slope form following this equation:

where y and x are variables, and [tex]x_{0}[/tex] and [tex]y_{0}[/tex] are x and y values of any chosen point on the curve (line)

m (slope) can be calculated by the equation [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex] where you need to find 2 chosen points on the line where [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the x and y values of the first set, and [tex]x_{2}[/tex] and [tex]y_{2}[/tex] are the x and y values of the second set.

Step-by-step explanation:

We can tell the difference among linear, quadratic, and exponential functions just by looking at equation as Exponent functions are rapidly increasing or decreasing, and the highest power of variable for a linear function is 1. The highest power of variable for a quadratic function is 2.

Linear functions are functions that are used to model phenomena that increase or decrease at a constant rate. These types of functions are polynomial functions with a highest exponent of one on the variable. The graphs of these functions are in the shape of a straight line.

Exponential functions are functions that have the variable in the exponent. They increase or decrease slowly then quickly or quickly then slowly.

Quadratic functions are the functions that have the highest power of variables equal to 2.

For example,

Linear Equation : The population of a family of rabbits starts with 2 rabbits and doubles every month.

Expoential Equation : Compound interest is example of exponential function.

Quadratic Equation : When you throw a ball (or shoot an arrow, fire a missile or throw a stone) it goes up into the air, slowing as it travels, then comes down again faster and faster and a Quadratic Equation tells you its position at all times!

Therefore, we can conclude that linear function have highest power of variable as 1 , exponent functions are quickly increasing or decreasing, Quadratic functions have the power of variables equal to 2.

The equation for the perpendicular bisector of the line segment whose endpoints are (-2, 4) and (-8,-6) is 3x + 5y + 20 = 0.

Given:

Endpoints of the line segment are (-2, 4) and (-8,-6).

Midpoint of the line segment = ( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )

                                                 = [tex]\frac{-2 +(-8) }{2}[/tex] , [tex]\frac{4 +(-6) }{2}[/tex]

                                                =( [tex]\frac{-10}{2}[/tex] , [tex]\frac{-2}{2}[/tex] ) = (-5, -1)

Slope of the line segment =  [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]

                                            = [tex]\frac{(-6) - 4 }{(-8) - (-2) }[/tex]

                                            = [tex]\frac{-10}{-6}[/tex] = [tex]\frac{5}{3}[/tex]

The line perpendicular to the line segment will have a slope of the negative reciprocal of the line segment which is -3/5.

Therefore, the perpendicular bisector passes through (-5,-1) and has a slope of -3/5.

Equation of the line will be,

y - y₁ = m(x - x₁)

⇒ y - (-1) = -3/5(x -(-5))

⇒ 5( y + 1) = -3(x + 5)
