The ratio of accessible parking spots to general parking spots 2:75.
Answer:
Approximately 2.6% of the total number of parking spots are designated as accessible.
Step-by-step explanation:
If the ratio of accessible parking spots to general parking spots is 2:75, this means that for every 2 accessible parking spots, there are 75 general parking spots. This can also be written as a fraction: 2/(2+75) = 2/77.
The fraction represents the proportion of the total number of parking spots that are designated as accessible. In this case, 2/(2+75) = 2/77 = approximately 0.026, or 2.6%. This means that approximately 2.6% of the total number of parking spots are designated as accessible.
It's important to note that the number of accessible parking spots should be determined based on the needs of the community and should meet or exceed the minimum requirements set by law. In the United States, the Americans with Disabilities Act (ADA) sets minimum requirements for the number of accessible parking spaces that must be provided in public parking lots. The exact number of spaces required depends on the size and type of the parking lot.

Answer:
y = 2/3x - 2
Step-by-step explanation:
To Literally Solve for y, we must first isolate it. This means putting it and its coefficient on the own side of the equation.
If you add, multiply, divide, subtract, put something to the power/root both sides of an equation, the final result will stay the same.
4x - 6y = 12
Subtract 4x on both sides.
4x - 4x -6y = 12 - 4x
Simplify.
-6y = 12 - 4x
Divide both sides by -6.
y = -2 + 2/3x
Adjusted the equation for clarity.
y = 2/3x - 2

The standard deviation of a binomial distribution is C. 3.46
What is standard deviation?Standard deviation is the measure of spread of a set of data.
Since a binomial trial has a probability of success of 0.2, and 75 trials are performed. To find the standard deviation, we use the formula for standard deviation of a binomial distribution.
What is the standard deviation of a binomial distribution?The standard deviation of a binomial distribution is given by σ = √(npq) where
n = number of possible outcomes, p = probability of successes and q = probability of failures = 1 - pGiven that for our binomial trial
n = 75p = 0.2 andq = 1 - p = 1 - 0.2 = 0.8So, substituting the values of the variables into the equation, we have that
σ = √(npq)
σ = √(75 × 0.2 × 0.8)
σ = √(75 × 0.16)
σ = √12
σ = 3.464
σ ≅ 3.46
So, the standard deviation is C. 3.46

classifying polynomials -8y
As the given polynomial -8y has only 1 term in is and hence it is classified as a monomial.
What are polynomials?A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.
x² 4x + 7 is an illustration of a polynomial with a single indeterminate x.
The quantity of terms allows for the classification (naming) of polynomials.
A polynomial may contain exponents, constants, and variables, but it never divides by a variable.
They may also contain one or more terms, but not an infinite quantity.
The degree can also be used to categorize polynomials (the largest exponent of the variable).
An expression with only one term is called a monomial.
The sole term in an expression needs to be non-zero in order for it to be a monomial.
Therefore, as the given polynomial -8y has only 1 term in is and hence it is classified as a monomial.

A function has an initial value of 3 and a rate of change of 4. Which table matches the description of the function
Answer:
The top left table.
Step-by-step explanation:
An initial value is the y-intercept, which is where the function touches the y-axis. If the initial value is 3, the coordinate must be (0,3). This rules out the both tables on the right.
The rate of change is how much the function's y values increase or decrease. If the rate change is 4, the y values increase by 4 each unit, which matches the top left table.

Find AEAE on the rhombus below when AD=4x+2AD=4x+2, DC=7x-13DC=7x−13 and BD=34BD=34.
The required length of AE will be 14 units on the given rhombus.
We know that all sides of a rhombus are equal, then note that AD equals DC, that is;
4x + 2 = 7x - 13
2 + 13 = 7x - 4x
15 = 3x
Divide both sides of the equation by 3
5 = x
If AD = 4x + 2, then when x = 5
AD = 4(5) + 2
AD = 20 + 2
AD = 22
So, triangle ADE may now be separated, with AD measuring 22 units and ED measuring 17 units (midpoint between points B and D). Line AE may be determined using Pythagoras' theorem, which states:
AC² = AB² + BC²
Where AC is the hypotenuse, and AB and BC are the two other sides
Substituting for values as given in the question, we now have;
AD² = ED² + AE²
22² = 17² + AE²
484 = 289 + AE²
484 - 289 = AE²
195 = AE²
√195 = AE
13.96 = AE
So, length AE ≈ 14 units (to the nearest whole number)
Thus, the required length of AE will be 14 units on the given rhombus.

The slope of the line passing through the points (-9, 6) and (-3, 9) is (1/2).
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is
y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

Use the coordinates J(7, 8), K(1, 2) and L(5, 2) for AJKL.
The orthocenter for AJKL is at point N. What is KN rounded to the nearest tenth?
The KN is 21.4 rounded to the nearest tenth.
What is an orthocenter?The orthocenter of a triangle is the place where the perpendicular drawn from the vertices to the opposing sides of the triangle intersect each other. The orthocenter for a triangle with an acute angle is located within the triangle. The orthocenter for a triangle with an acute angle is outside the triangle.
Now we need to find the slope of JL.
From that we have to find the slope of the perpendicular line through B.
Slope of JL= (y₂ - y₁) / (x₂ - x₁)
J (7, 8) and L (5, 2)
here x₁= 7,y₁ = 8, x₂ = 5 and y₂ = 2
= -6 / -2
= 3
Slope of the altitude KM = -1/ slope of JL = -1/3
Equation of the altitude KM : (y - y₁) = m (x -x₁)
Here K(1,2);
(y - 2) = -1/3 (x -1)
(y - 2) = -x/3 +1/3
Now we need to find the slope of JK.
From that we have to find the slope of the perpendicular line through D.
Slope of KL= (y₂ - y₁) / (x₂ - x₁)
J(7,8) and K(1,2)
here x₁= 7,y₁ = 8, x₂ = 1 and y₂ = 2
= 1
Slope of the altitude JO = -1/ slope of JL
= -1
Equation of the altitude JO : (y - y₁) = m (x -x₁):
(y - 8) = -1 (x - 7)
Solving the equation, x = 21 and y = -6
So the orthocenter N is (21 , -6)
Now the distance of KN is = √(21 - 1)² + (-6 -2)²
=√464
= 21.5
Therefore, the KN is 21.5 rounded to the nearest tenth.

With a total pay last week of $4720 and a 2.5% commission on sales, she made 275 in sales.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.
Here,
The money earned by sales=2.5%*600
=$15
Let the total sales be x,
600+15x=4720
