Jalla's hourly wage is $11.791. Round her salary to the nearest cent
Jalla's hourly wage, when rounded to the nearest cent, is $11.79.
Explanation:To round Jalla's wage to the nearest cent, we must look at the numbers following the decimal. In this case, Jalla's hourly wage is $11.791. Decimal rounding rules tell us that if the number following the decimal is equal to 5 or more, round up; otherwise, round down. In this case, the number after the decimal is 9, more than 5, so we round the second decimal place up. Therefore, rounding to the nearest cent, Jalla earns $11.79 per hour, her rounded wage.

Gaff has used 331/3 of his monthly minutes on his cell phone plan. If he already used 200 mintues, how many does he have left this month?
The first step to solve this problem is to compute for the total minutes allowable in his cell phone plan. To compute for this, you have to divide the number of minutes consumed by the fraction of the time consumed.
200 minutes / 33 1/3% = 600 minutes
To compute for the remaining minutes left for this month, you have to deduct the consumed minutes to the total allowable minutes in his plan.
600 minutes – 200 minutes = 400 minutes left
Which transformation gives the same result as a reflection over the y-axis followed by a reflection over the x-axis?
a.A rotation of 180° around the origin
b.A rotation of 270° around the origin
c.A translation to the left and then down
d.A rotation of 90° around the origin
Answer:
a. A rotation of 180° around the origin.
Step-by-step explanation:
A rotation of 180° around the origin would give us the same result as a reflection over the y-axis followed by a reflection over the x-axis. When we perform this rotation, we take each of its points through the transformation (x,y) ---> (-x, -y). This means that we would multiply the coordinates of each of the points on the shape by a negative. This is equivalent to reflecting a shape over the x-axis and the y-axis.
the length of a rectanglr exceeds its width by 5 inches, and the area is 84 square inches. what are the length and width of a a rectangle
The area is the product of length and width, which is to say that the length and width are factors of the area.
Assuming the dimensions are integers, you want factors of 84 that differ by 5.

if the graph of a quadratic function intersects with the x axis two times, how many solutions are there to the equation when set equal to zero
Final answer:
A quadratic function intersecting the x-axis two times means there are two distinct real solutions to the equation when it is set to zero.
Explanation:
When a quadratic function intersects the x-axis two times, it indicates that the corresponding quadratic equation has two distinct real solutions.
This is because the points where the graph intersects the x-axis are the zeros of the function, which are the solutions to the equation when set equal to zero.
To find the solutions to a quadratic equation of the form ax² + bx + c = 0, one can use the quadratic formula, which is:
[tex]x = (-b \pm (b^2 - 4ac)) / (2a)[/tex]
If the discriminant (b² - 4ac) is greater than zero, this indicates two distinct real solutions.

Maya's penny bank is 3/10
full. After she adds 520
pennies, it is
4/5 full. How many pennies can Maya's bank hold?
Maya's bank can hold 1733 pennies.
Explanation:To find out how many pennies Maya's bank can hold, we can set up an equation using the given information. Let's start with the fact that Maya's bank is 3/10 full before adding 520 pennies. This means that 3/10 of the bank's capacity is equal to 520 pennies. We can use this information to find the total capacity of the bank.
Since 3/10 of the bank's capacity is equal to 520 pennies, we can set up the equation (3/10)x = 520, where x represents the total capacity of the bank in pennies.
To solve for x, we can multiply both sides of the equation by 10/3 to cancel out the fraction. This gives us x = (10/3) * 520 = 1733.33. Since we cannot have a fraction of a penny, we round down to the nearest whole number. Therefore, Maya's bank can hold 1733 pennies.

The midpoint of the line segment from upper p 1p1 to upper p 2p2 is left parenthesis negative 1 comma 5 right parenthesis(−1,5). if upper p 1p1equals=left parenthesis negative 4 comma 6 right parenthesis(−4,6), what is upper p 2 question mark p2?
Final answer:
To find the coordinates of point P2 when given the midpoint M(-1, 5) and point P1(-4, 6), we use the midpoint formulas, resulting in P2 having the coordinates (2, 4).
Explanation:
The midpoint of a line segment is the point that is exactly halfway between the endpoints of the line segment. By definition, the midpoint M(x, y) can be found using the endpoints P1(x1, y1) and P2(x2, y2) with the formulas:
x = (x1 + x2)/2y = (y1 + y2)/2To find P2, we solve for x2 and y2 using the midpoint M(-1, 5) and the given point P1(-4, 6):
x2 = 2x - x1 = 2(-1) - (-4) = -2 + 4 = 2y2 = 2y - y1 = 2(5) - 6 = 10 - 6 = 4Therefore, the coordinates of point P2 are (2, 4).
Final answer:
The coordinates of P2 are (6, 4).
Explanation:
The midpoint of a line segment can be found by taking the average of the x-coordinates and the average of the y-coordinates of the two endpoints. In this case, the midpoint is (-1, 5), and one endpoint is (-4, 6). To find the other endpoint, we can use the formula:
x-coordinate of P2 = 2 * (x-coordinate of midpoint) - x-coordinate of P1 = 2 * (-1) - (-4) = 2 + 4 = 6
y-coordinate of P2 = 2 * (y-coordinate of midpoint) - y-coordinate of P1 = 2 * (5) - 6 = 10 - 6 = 4
Therefore, the coordinates of P2 are (6, 4).

Brayden is simplifying the expression 4n – (n – 3)2. He begins by distributing the negative to the terms inside the parentheses. What should he have done instead? combine like terms square the binomial cube the binomial rewrite the expression as a fraction
The correct step is to square the binomial (n - 3)² before combining like n terms.
Brayden is working on simplifying the expression 4n – (n - 3)². The correct initial step is not to distribute the negative inside the parentheses, but rather to square the binomial. This involves applying the binomial square formula [tex](a - b)^2 = a^2 - 2ab + b^2[/tex], to the expression inside the parentheses. Therefore, simplification should start with (n - 3)² resulting in [tex]n^2 - 6n + 9[/tex]. After this, Brayden should combine like n terms by adding or subtracting them to simplify the expression further.
