Answer: 1.2 individual signing up the day of the activitiy get charged 20% more
Step-by-step explanation:
We have a community center that charges x dollars for a summer activity if individuals are signed up before the day of the activity but if individuals who sign up on the day of the activity are charged a fee of x + 0.20x dollars.
We have to determine which expression represents the fee for signing up the day of the activity and investigate what does it mean about the fee.
What do you understand by the Equation Modelling of the process?Equation modelling of a process is a way to formulate the given process mathematically. Generally, it is used in such problems where something is produced on giving some input.
According to question, we have the following equation describing the charging rates -
f(x) = x + 0.2x = x + [tex]\frac{1}{5}x[/tex]
In this the expression, the part [tex]\frac{1}{5}x[/tex] represents the fee for signing up on the day of the activity.
It also indicates that if you you are late for sign up and you are signing on the day of the activity then you will have to pay an extra fine of [tex]\frac{1}{5}[/tex] times of the fees if you signed up before the day.

What is percent?A number or ratio which can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of something, we mean that it is 50% of everything.
As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics.
Let the required percentage be x%.
A/c to question,
[tex]\frac{x}{100} * 50= 125\\\\ x=250[/tex]
That is, required percentage is 250%.
Hence, option C is correct.

Can someone help me know how to do this problem In finding what I can put in for (c) in order to get 2 imaginary solutions
Answer:
To get 2 imaginary solutions, c must be less than -2
Step-by-step explanation:
The general form of the quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
Solve the quadratic equation by using the formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The equation to solve is:
[tex]-2x^2+4x+c=0[/tex]
In our equation: a=-2, b=4, c=unknown
For the roots to be imaginary, the argument of the square root must be negative, that is:
[tex]b^2-4ac<0[/tex]
Substituting the known values:
[tex]4^2-4(-2)c<0[/tex]
[tex]16+8c<0[/tex]
Subtracting 16:
[tex]8c<-16[/tex]
Solving:
[tex]c<-2[/tex]
Thus, to get 2 imaginary solutions, c must be less than -2

Which single conversion factor would you use to find out how many miles are in 8,462 yards?
Answer:
A. 1 mile / 1,760 yards
Step-by-step explanation:
A single conversion factor is a number that we can multiply directly with 8,462 yards to determine how many yards are there in 8,462 yards.
Since 1 mile is to 1,760 yards, the single conversion factor to use in determining how many miles a number of yards would be = 1 mile/1,760 yards = [tex] \frac{1}{1,760} [/tex]
Thus, to find out many miles are in 8,462 yards, multiply by [tex] \frac{1}{1,760} [/tex].
[tex] 8,462*\frac{1}{1,760} = \frac{8,462}{1,760} = 4.8 [/tex] miles

A 12-foot ladder that is leaning against a wall makes a 75.5 degree angle with the level ground.
Which of the following equations can be used to determine the height y, above the ground, in feet, that the ladder touches the wall
A. Sin 75.5 = 12/y
B. Cos 75.5 = y/12
C. Sin 75.5 = y/12
D. Cos 75.5 = 12/y
Answer:
C. Sin 75,5 = y/12
Step-by-step explanation:
This angle can be calculated using the law of sine:
sin(angle)=opposite cathete/hypothenuse
sin(angle)=wall/ladder
In this exercise we want to calculate the height of the ladder, so the equation is changed afterwards.
sin(angle)=wall/ladder
sin(75,5°)=12ft/y
The height y above the ground in feet is ; (C ) sin 75.5 = y / 12
Determine the equation that can be used to determine y
The ladder, the horizontal ground and the vertical height above the ground form a right angle triangle are ;
The vertical height y = opposite
Length of ladder = hypotenuse
Horizontal ground = adjacent.
According to trigonometry, sine of an angle is opposite/hypotenuse
sin 75.5 = y/12.
In conclusion, the height y above the ground in feet is sin 75.5 = y / 12.

Professor Burger orders flowers to be delivered to his mother. The flowers cost $59.95, not including tax. A bouquet of flowers is shown. Its price tag reads fifty-nine dollars and ninety-five cents. If there is a 6% sales tax, what is the total cost of the flowers to the nearest cent? Enter the correct answer in the box.
Answer:
$63.55
Step-by-step explanation:
Taxes are charges paid by individuals and enforced by the government in other to fund government spending and various public expenditures.
The flowers cost $59.95 and tax is 6%.
Tax = 6% of flower cost = 0.06 × $59.95 = $3.6
The total cost of the flowers is the sum of tax and the cost of flowers, hence:
Total cost of the flowers = $59.95 + $3.6
Total cost of the flowers = $63.55

Quinn earned $24.50 dog-sitting and $12.70 for recycling cans. Find thetotal amount he earned.
Answer: $37.20
Step-by-step explanation:
24.50+12.70=37.20
Quinn earned a total amount of $37.20 which is the addition of the earnings from dog-sitting and the recycling cans.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
We have been given that Quinn earned $24.50 for dog-sitting and $12.70 for recycling cans.
We have to determine the total amount he earned.
The total amount is the addition of the earnings from dog-sitting and the recycling cans.
The total amount = earnings from dog-sitting + earnings from the recycling cans.
The total amount = $24.50 + $12.70
The total amount = $37.20
Therefore, he earned a total amount of $37.20.

LITERAL EQUATIONS: A literal equation is one consisting of all letters (or at least mostly letters). The Latin word literalis means "of or belonging to letters or writing," giving the term literal equations its meaning. We can solve literal equations the same way we solve any other equation. We just need to be told which variable (letter) we are solving for. To solve a - 2 = 5 for a, we would add two to each side of the equation. To solve b - r = z for b, we would add r to each side of the equation. What would the resulting solution be ? b = z - r z = b - r r = b - z b = r + z
Answer:
D. b = r+z
Step-by-step explanation:
Given the expression b-r = z, we are to solve for b. To do this, we will add 'r' to both sides of the equation as shown;
b-r+r = z+r
Since -r+r = 0, substitute:
b+0 = z+r
b = z+r
Hence the resulting equation when r is added to both sides of the equation is b = z+r
Hence option D is correct

We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.
The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:
2x + 3y + 4z = 15.3 (1)
The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:
4x + y + 2z = 10.9 (2)
The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:
5x + 2y + z = 13.7 (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = $1.5, y = $2.5 and y = $1.2
The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2
