The inequality equation is = 15x +10y>=110. This equation represents the possible values for the number of hours lifeguarding and the number of hours washing cars = 15x +10y >= 110
Hourly wage of Cooper working as a lifeguard = $15
Hourly wage of Cooper washing cars = $10
Minimum income required this week = $110
Let x be the number of hours Cooper works as a lifeguard and y be the number of hours Cooper works washing cars
Income from working as a lifeguard based on the number of hours = 15x
Income from working washing cars based on the number of hours = 10y
Formulating the inequality equation we get the following:
15x + 10y >=110

The correct answer is option C that is on step 4 - 5 the right side should have been ± i.
A quadratic polynomial function is the one which can be written in the form ax² + bx + c = y where a, b and c are coefficients and x, and y are independent and dependent variables respectively. The quadratic polynomial function is solved using Completing the square method. In this method the quadratic polynomial is converted into the form (x + a)² in order to find the roots of the quadratic polynomial. Here, the steps 1, 2 and 3 are correct but in step 4 after taking square root on both the sides the value of √-1 is not taken as ± i and further it is solved. This becomes an error as we know that the value of √-1 = ± i and if not taken properly errors occur.

Answer:
bottom right rectangle: 5x − y
bottom circle: 6x
Step-by-step explanation:
First, solve for the bottom right rectangle by finding the difference between the top right rectangle and the middle right circle:
(9x + 4y) − (4x + 5y)
= (9x − 4x) + (4y − 5y)
= 5x − y
Next, to find the bottom circle, add the bottom left rectangle with the bottom right rectangle (the one we just solved for):
(x + y) + (5x − y)
= (x + 5x) + (y − y)
= 6x

A $100 sweatshirt is put on sale for 40% off. One week later, the sale price is marked up by 40%. Will the marked-up price of the sweatshirt be less than, greater than, or equal to the initial price of $100?
The new price after being marked up is less than initial price of $100.
The price of sweatshirt after discount = 100 - 40%×100
Converting percentage to fraction
The price of sweatshirt after discount = 100 - (40/100)×100
The price of sweatshirt after discount = 100 - 40
Performing subtraction
The price of sweatshirt after discount = $60
The marked up sale price = 60 + 40%×60
Converting percentage to fraction
The marked up sale price = 60 + (40/100)×60
Cancelling zero and performing multiplication
The marked up sale price = 60 + 24
Performing addition
The marked up sale price = $84
Thus, the marked up price after discount will be less than the initial price of $100.

What is an Algebraic Expression?An algebraic expression in mathematics is one that contains variables, constants, and algebraic operations (addition, subtraction, etc.). Terms comprise expressions. These expressions use unknown coefficients, constants, and variables. These three terms combined are referred to as an expression.It should be noted that an algebraic expression lacks sides and the equal sign, in contrast to an algebraic equation.You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.Given:
Algebraic expression is 2⁴ + 9x + 2
Where x = 2
So substituting the value of x to find the result of the expression,
2⁴ + 9x + 2 = 16 + 9×2 + 2 = 16 + 18 + 2 = 36

In a cyclic quadrilateral, opposite angles is supplementary.
=> 3x - 59 + 2x - 1 = 180
=> 5x - 60 = 180
=> 5x = 180 + 60
=> 5x = 240
=> x = 48
Angle A = 2(48) + 4 = 100
Also, A + C = 180
=> C = 180 - 100
=> C = 80
kareem needs to make a total of 40 deliveries this week. so far hes completed 28 of them. what percentage of deliveries has he completed?
thank youuuu
If Kareem has completed 28 out of the 40 deliveries he needs to fulfill this week, then he has completed 70 percentage of his total deliveries.
As per the question statement, Kareem needs to make a total of 40 deliveries this week, and he has completed 28 thus far.
We are required to calculate the percentage of deliveries, Kareem has completed so far.
To solve this question, we simply need to divide the number of deliveries completed so far, by the total number of deliveries Kareem needs to fulfill in the week, and then multiply the quotient with 100, to obtain our desired answer.
Here, number of deliveries completed so far by Kareem = 28,
And, total number of deliveries Kareem needs to fulfill = 40.
Therefore, percentage of deliveries, Kareem has completed so far
= [(28/40) * 100]
= [(7/10) * 100]
= (7 * 10)
= 70%.

A number line is a representation of a graduated straight line in elementary mathematics that serves as a visual representation of the real numbers. It is assumed that every point on a number line corresponds to a real number, and that vice versa. Frequently, the integers are represented by specially marked, uniformly spaced points on a line. The line includes all real numbers, continuing indefinitely in both directions, as well as numbers that are in between the integers, even though the image only displays the integers from -3 to 3. It is frequently employed as a teaching tool, particularly when teaching simple addition and subtraction with negative numbers.

if the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, No , it does not change the value of p(odd number) .
a) The sample space is the set of all possible outcomes. By definition, the elements of a set should not be repeated. Hence, the sample space S = {1, 2, 3}
However, the sample is not equiprobable because each element has different probabilities.
b) P(odd number) = number of odd digits / number of faces = 4/6=2/3
Note that the odd numbers are 1 (on three faces) and 3 (on one face).
c) The fact the die has been biased does not change the possible outcomes. It only changes the probability of getting any given number.
d) Because the 3-face has been loaded, this probability changes. In fact, it is calculated thus:
Let's assume the probability for 1 or 2 is . Then that of 3 is (because it is twice the others). The sum of probabilities must be 1.

$52,900
$53,340
$53,914
$55,573
By using the equation for the line of best fit, the salary for an employee with 7 years of experience is: D. $55,573.
What is a line of best fit?A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between a data.
In this scenario, the employee's years of experience would be plotted on the x-axis of the scatter plot while salary would be plotted on the y-axis of the scatter plot.
By critically observing the scatter plot (see attachment) which models the data in the given table, we can reasonably and logically deduce that the equation for the line of best fit is given by:
y = 2233.3x + 39940
Next, we would use the equation for the line of best fit to predict the salary for an employee with 7 years of experience:
y = 2233.3(7) + 39940
y = 15,633.1 + 39940
y = 55,573.1 ≈ $55,573.

How to determine the area of the circleThe formula for determining the formula for circumference of a circle is expressed as;
Circumference = 2 πr
Given that;
π has a fractional value of 22/ 7 and a decimal value of 3. 14r is the radius of the circleNow, we have to substitute the value of circumference of the circle as 60cm
We have;
60 = 2 πr
Now, substitute the value for π into the equation, we have;
60 = 2× 3.14r
Multiply the values, we get;
60 = 6.28r
Make 'r' the subject of formula in the equation
r = 60/6.28
r = 9.55cm
But we know that e formula for area of a circle is expressed as;
Area = πr²
Now, substitute the value of radius into the formula, we have;
Area = 3. 14(9.55)²
Find the squares
Area = 3.14(91.2025)
