Evelyn is working two summer jobs, making $18 per hour lifeguarding and making $11 per hour tutoring. In a given week, she can work a maximum of 15 total hours and must earn no less than $200. If Evelyn worked 8 hours lifeguarding, determine the maximum number of whole hours tutoring that she can work and still meet her requirements.
Answers
Given Evelyn's hourly rates for both of her jobs and the total number of working hours she has, Evelyn can work a maximum of 7 hours tutoring if she has already spent 8 hours lifeguarding.
Explanation:To solve this problem, we first calculate the total earning from lifeguarding by multiplying the hourly rate by the number of hours she worked, which results in $18 * 8 = $144. The minimum total earning she must make is $200, so she still needs to earn $200 - $144 = $56. Since she is making $11 per tutoring hour, she will need to work a minimum of $56 / 11 which is approximately 5 hours. However, these are still part of the total of 15 hours maximum she can work, and she has already worked 8 hours lifeguarding, meaning she can work at most 15 - 8 = 7 hours tutoring in the remaining time.

The maximum number of whole hours tutoring that Evelyn can work while still meeting her requirements is 5 hours.
To solve this problem, we can use a combination of inequalities to represent the given constraints.
We need to solve these inequalities simultaneously to find the maximum number of whole hours Evelyn can work as a tutor.
1. The first inequality:
[tex]\[ x + 8 \leq 15 \][/tex]
[tex]\[ x \leq 15 - 8 \][/tex]
[tex]\[ x \leq 7 \][/tex]
2. The second inequality:
[tex]\[ 18(8) + 11x \geq 200 \][/tex]
[tex]\[ x \geq \frac{56}{11} \][/tex]
[tex]\[ x \geq 5.09 \][/tex]
Since the number of tutoring hours must be a whole number, Evelyn can work a maximum of 5 whole hours tutoring and still meet her requirements.
Therefore, the maximum number of whole hours tutoring that Evelyn can work while still meeting her requirements is 5 hours.

#SPJ6
Final answer:
The independent variable is the number of apples purchased, as it determines the dependent variable, which is the total amount spent on apples in the grocery bill.
Explanation:
The independent variable in this scenario is the number of apples purchased (represented by a). This is because the independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. In this case, Tyler decides how many apples to buy, and that decision directly affects the total cost, which is the dependent variable (g). The price of an apple, the weight of the apples, and the amount on the grocery bill are all dependent on the number of apples Tyler chooses to purchase. To find the total amount spent on apples, one would multiply the number of apples purchased by the cost per apple.

Answers
Given:
It is given that LON is a straight line. The measure of ∠LOM = (4x + 30)° and the measure of ∠MON = (8x + 90)°
We need to determine the value of m∠MON
Value of x:
Since, LON is a straight line and the angles LOM and MON are linear pairs of angles.
Since, linear pair of angles add up to 180°
Thus, we have;
[tex]\angle LOM+\angle MON=180^{\circ}[/tex]
Substituting the values, we get;
[tex]4x+30+8x+90=180[/tex]
[tex]12x+120=180[/tex]
[tex]12x=60[/tex]
[tex]x=5[/tex]
Thus, the value of x is 5.
Value of m∠MON:
The measure of ∠MON can be determined by substituting x = 5 in the expression (8x + 90)°, we have;
[tex]m\angle MON=(8(5)+90)^{\circ}[/tex]
[tex]m\angle MON=(40+90)^{\circ}[/tex]
[tex]m\angle MON=130^{\circ}[/tex]
Thus, the measure of ∠MON is 130°
the lateral area of a cone is 558pi cm^2 the radius is 31 cm. find the slant height to the nearest tenth
Answers
The slant height of the cone is 39.7 cm
Explanation:
Given:
Lateral surface area of a cone = 558π cm²
Radius, r = 31 cm
Slant height, l = ?
We know:
[tex]A = \pi r\sqrt{h^2+r^2}[/tex]
Where,
h is the height of the cone
r is the radius
Solving the equation further:
[tex]558\pi = \pi r\sqrt{h^2+r^2} \\\\558 = 31\sqrt{h^2+(31)^2} \\\\(18)^2 = h^2 + 961\\\\324 = h^2+ 961\\\\h = 25.23[/tex]
Lateral height, H = ?
Applying pythagoras theorm,
(H)² = (h)² + (r)²
(H)² = (25.23)² + (31)²
(H)² = 636.55 + 961
(H)² = 1597.55
H = 39.7 cm
Therefore, the slant height of the cone is 39.7 cm

Minimum price: Increases.
Maximum price: Remains the same.
Range: Increases.
Mean (Average) price: Cannot be determined.
When the kid's meal is added to the menu, the effect on the statistics of the meal prices can be determined as follows:
Minimum Price: Increases
Adding the kid's meal, which costs $2.35, to the menu will increase the minimum price.
Therefore, the value of the minimum price statistic will increase.
Maximum Price: Increases
Since the maximum price of the kid's meal ($2.35) is lower than the previous maximum price of $12.10, adding the kid's meal to the menu will not change the maximum price.
Therefore, the value of the maximum price statistic remains the same.
Range: Increases
The range is calculated as the difference between the maximum and minimum prices.
As the minimum price increases while the maximum price remains the same, the difference between them (the range) will increase.
Therefore, the value of the range statistic will increase.
Mean (Average) Price: Cannot be determined
To determine the effect on the mean price, we would need information about the number of meal options available and their individual prices. Without this information, we cannot determine whether the mean price will increase, decrease, or remain the same.
Therefore, the value of the mean price statistic cannot be determined.
In summary:
Minimum price: Increases
Maximum price: Remains the same
Range: Increases
Mean (Average) price: Cannot be determined

What is the sum of the measures of the exterior angles of this triangle?
A triangle has angles A, C, 51 degrees. Angle A has exterior angle B and angle C has an exterior angle with measure of 112 degrees.
Answers
The measure of ∠B is 119°.
What is the exterior angle?An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.
All the exterior angles are of the same measure, and therefore, their measure is (360/n)°.
The angle adjacent to 112° will form a straight angle along with 112° adding to 180° which makes ∠C=68°
Then;
a+c+51°= 180°
a+68°+51° = 180°
a+119° = 180°
a = 180° - 119°
a = 61°
Now,
a+b = 180°
61+b = 180
b = 180-61
b = 119°

what rule matches the function represented by the table?
Answers
Let's try a line
y = mx + b
From (0,4):
4 = 0x + b
b = 4
So far we have
y = mx + 4
From (1,1)
1 = m(1) + 4
-3 = m
Our rule is y = -3 x + 4
Let's check the other points:
-3(-4)+4 = 12+4 = 16 good
-3(4)+4 = -12+4 = -8 good
-3(9) + 4 = -23 good
Answer: y = -3 x + 4
The rule matching a function as shown by a table can be determined by analyzing the difference and relationship between x-values and y-values. This might represent a linear, exponential, or quadratic relationship, which can be described by a range of mathematical equations.
Explanation:Unfortunately, without having the actual table and data, it is hard to give an accurate rule for the function. However, generally, in order to define a rule that matches a function represented by a table, you would need to discern a pattern between the inputs (often represented by the x-values) and the outputs (represented by the y-values).
In some cases, this might be a simple linear rule where each step in the x-values increases or decreases the y-values by a consistent rate; this would represent a formula of the format y = mx + b, where m is the change in y over the change in x, and b is the y-value when x = 0. Alternately, more complex relationships (such as exponential or quadratic rules) might be represented and would need different formulas to be described properly.
Determining the rule can often involve finding the rate of change between pairs of data points and discerning what kind of relationship this reveals. The explanation and answer would then match this established pattern.

What is the image of (4,-7) after a reflection over the y-axis?
Answers
Answer:
It would be a point which is at (-4,-7).
The image of the point (4,-7) after a reflection over the y-axis is (-4,-7). This happens because the y-axis is the axis of symmetry during a reflection over this axis, changing the x-coordinate's sign while keeping the y-coordinate constant.
Explanation:The image of a point after a reflection over the y-axis results in the x-coordinate of the point changing its sign. Therefore, the image of the point (4,-7) after a reflection in the y-axis would be (-4,-7). In other words, you move the point 4 units to the left across the y-axis while the y-coordinate remains unchanged.
This process is derived from the concept that the y-axis is the axis of symmetry in a reflection over the y-axis. As such, points on one side of the axis are mirrored on the other side, changing only the sign of the x-coordinate and keeping the y-coordinate constant.
A helpful way to visualize this is by drawing a coordinate grid and plotting the point (4,-7). By reflecting this point over the y-axis, you will see it lands at the point (-4,-7).

a - b = 5
Use the substitution method.
a = 5 + b
(5 + b)*b = 6800
5b + b*b = 6800
bb + 5b - 6800 = 0
b = -5/2 + root(25 - 4*1*(-6800)) /2
b = -5/2 + 165/2
b = 80
