If you were a salaried employee paid weekly, how many times would you be paid for an entire year?
Answer: Most employers expect their exempt employees to work the number of hours necessary to get their jobs done. It doesn't matter if that takes more or fewer than 40 hours per week. Even if your exempt employee works 70 hours in a week, you are still only required to pay them their standard base salary If you use a payroll processing service, there is a cost for each check processed. But either way, processing paychecks more frequently will cost more, such as if you process paychecks every other week (26 times a year) rather than bi-monthly (24 times a year).
Step-by-step explanation:
The temperature of the Pacific Ocean varies inversely with the depth. If the temperature at 2000 m is 2.2 degrees Celsius, what is the temperature at a depth of 4000 m? Round your answer to the nearest tenth degree.
The temperature at a depth of 4000 m will be 1.1 degrees Celsius.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
Given that the temperature varies inversely with the depth
Let T be the temperature and D be the depth, then the inverse variation equation is:
T = k/D
Where variation constant = k
If the temperature at 2000 m is 2.2 degrees Celsius, then the equation is:
2.2 = k/2000
k = 4.400
So T = 4400/D
when D = 4000 m
T = 4400/4000
T = 44/40
T = 1.1
Thus, the temperature at a depth of 4000 m will be 1.1 degrees Celsius.

Two cyclists, 40 miles apart, start riding toward each other at the same time. One cycles 3 times as fast
as the other. If they meet 2
hours later, what is the speed (in mi/h) of the faster cyclist?
Answer:
15 mph
Step-by-step explanation:
The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...
faster cyclist distance : slower cyclist distance = 3 : 1
Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.
That distance took 2 hours for the faster cyclist, so the speed was ...
speed = distance/time = 30 mi/(2 h) = 15 mi/h
John has a 100 cm cubed pencil holder. If John wants to hide a pencil in the pencil holder (so the pencil holder) what is the longest length of pencil he can hide
Therefore, the longest length of pencil that John can hide in the pencil holder is approximately 127.32 cm (rounded to two decimal places).
Given that John has a 100 cm³ pencil holder, the longest length of pencil he can hide in the pencil holder can be found by using the formula for the volume of a cylinder which is given by: V = πr²h where r is the radius of the cylinder and h is the height of the cylinder.The volume of a cylinder can also be expressed as V = lwh where l is the length of the cylinder, w is the width of the cylinder and h is the height of the cylinder.
If we assume that the pencil is cylindrical in shape, then its volume can be given by V = πr²l where r is the radius of the pencil and l is the length of the pencil.Since the volume of the pencil holder is given to be 100 cm³, then we have:100 = πr²h (Equation 1)
Now, we need to find the value of l that can fit inside the pencil holder. We can use the formula for the volume of the pencil to do this as follows:
V = πr²lLet V = 100 cm³ and
r = 0.5 cm
(since the pencil holder is cylindrical in shape, we can assume that it has a radius of 0.5 cm)Then, we have:100 = π(0.5)²lSolving for l, we get:
l = 100 / (π(0.5)²)
l = 100 / (0.7854)l ≈ 127.32 cm

Mai has proven that triangle WYZ is congruent to triangle WYX using the Side-Side-Side Triangle Congruence Theorem. Since corresponding parts of
congruent triangles are congruent, angle ZWY is congruent to angle XWY and angle ZYW is congruent to angle XYW.
True or False: Mai can now conclude that diagonal WY bisects angles ZWX and ZYX.
True
O False
It is true, Mai can conclude that the diagonal WY bisects the angles ZWX and ZYX
Since Mai has proven triangles WYZ and WYX to be congruent by the SSS triangle Congruence Theorem, she can conclude that:
Diagonal WY bisects angles ZWX and ZYX because:
all corresponding parts of both triangles are congruent. (Option A).
If two triangles are proven to be congruent to each other, it means that all three pairs of corresponding sides and angles of both triangles are congruent and equal to each other.
Thus, since Mai has proven triangles WYZ and WYX to be congruent by the SSS Triangle Congruence Theorem, therefore, all corresponding parts of both triangles are congruent.
If this is so, then Mai can conclude that angles ZWX and ZYX are bisected by diagonal WY. (Option A is correct).

The functions f(x) and g(x) are shown on the graph.
Using f(x), what is the equation that represents g(x)?
g(x) = log3(x) – 4
g(x) = log3(x) + 4
g(x) = log3(x – 4)
g(x) = log3(x + 4)
We can see that g(x) is a translation of 4 units to the left of f(x), then:
g(x) = log₃(x + 4).
How to get the equation that represents g(x)?
Here we can see that g(x) is a shift of f(x). Is clear that the asymptote of g(x) is 4 units to the left of the asymptote of f(x), so we can say that g(x) is a shift of 4 units to the left of f(x).
Remember that for a given function f(x), an horizontal shift of N units is given by:
g(x) = f(x + N).
If N is positive, the shift is to the left.If N is positive, the shift is to the right.Then a shift of 4 units to the left is written as:
g(x) = log₃(x + 4).

Martha is saving money to buy a new computer that costs $1800. She received $200 for her birthday and has a job where she makes $150 each week.
a) Make a table and a graph for this situation.
b) Explain how you can use the table or graph to predict how many weeks it will take Martha to earn enough money to pay for the new computer.
c) Explain how you can tell from both the table and the graph whether this is an example of linear or non-linear growth.
a) A table and a graph for this situation is shown in the image below.
b) You can use the table or graph to predict how many weeks it will take Martha to earn enough money to pay for the new computer by comparing the week when her savings are both equal.
c) Since the x-value and y-value in both the table and the graph increase simultaneously, it is an example of linear growth.
How to complete the table and graph the function?In this scenario, the variable x would represent the number of weeks while the variable y would represent the total amount of savings. Since Martha received $200 for her birthday and makes $150 each week, a linear equation in slope-intercept form that models the situation is given by;
y = mx + c
y = 150x + 200
Next, we would use an online graphing calculator to make a table and a graph for this situation as shown in the image attached below.
Part b.
The table and the graph both have the total amount of savings (y) equal to $1,850 when x is equal to 11 weeks. This ultimately implies that, it would take Martha between 11 weeks to save enough money to buy this new computer.
Part c.
By critically observing the table and the graph, we can logically deduce that there is a linear relationship between the variables because both the x-value and y-value increase simultaneously.
Therefore, this is an example of a linear growth.

How would you solve this using the elimination method? Thanks!
Answer:
x = -1,375
y = -5
Step-by-step explanation:
{-8x + y = 6, / : (-1)
{-8x + 3y = -14;
Multiply the first equation by -1, so that we could eliminate 8x:
+ {8x - y = -6,
{-8x + 3y = -14;
----------------------
4y = - 20 / : 4
y = -5
Now, make x the subject from the first equation (you can do it from the 2nd one instead):
8x = -6 + y / : 8
x = -0,75 + 0,125y
x = -0,75 + 0,125 × (-5) = -0,75 - 0,625 = -1,375

The width of the rectangular base of the pyramid is approximately 3.74 cm, and the length is approximately 11.22 cm (since it is given as 3x+1).
What is base of a pyramid?The base of a pyramid can be any polygon, such as a square or a triangle, but the height must always be measured perpendicular to the base.
Define the term dimensions?Dimensions refer to the number of coordinates needed to specify the location of an object in space.
Based on the given information, we can set up an equation to solve for x, which is the width of the rectangular base of the pyramid:
Volume of pyramid = 1/3 × base area ×height
96 = 1/3 ×(3x+1) × x ×12
Simplifying the equation:
96 = 4x² + (4/3)x
Multiplying both sides by 3 to eliminate the fraction:
288 = 12x² + 4x
Rearranging the equation into a quadratic form:
12x² + 4x - 288 = 0
Dividing both sides by 4 to simplify the equation:
3x² + x - 72 = 0
We can then use the quadratic formula to solve for x:
x = (-b ± \(\sqrt{(b^2-4ac)}/2a\)
where a = 3, b = 1, and c = -72.
Plugging in the values:
x=(-1±\(\sqrt{1^2-4(3)(-72)} /2(3)\))
x=(-1±\(\sqrt{1+864} /6\))
x = (-1 ±\(\sqrt{865} /6\) )
Since the width of the base cannot be negative, we take the positive solution:
x = (-1 + √(865) / 6
Therefore, the width of the rectangular base of the pyramid is approximately 3.74 cm, and the length is approximately 11.22 cm (since it is given as 3x+1).
