Answer
Regular pay = $388
Overtime pay = $87.3
Gross pay = $388 + $87.3
= $475.3
Explanation
During the first week of January, Patricia Morgan worked 46 hours at a rate of $9.70 per hour for regular hours.
For overtime, the pay is 1.5 times the normal rate. That is, 1.5 × $9.70 = $14.55
So, working for 46 hours, that is, 40 hours regular pay rate, and 6 hours overtime pay rate.
Regular pay = 40 × $9.70 = $388
Overtime pay = 6 × $14.55 = $87.3
Gross pay = Regular pay + Overtime pay
= $388 + $87.3
= $475.3
Hope this Helps!!!
What is the domain of the square root function graphed below?
On a coordinate plane, a curve opens down to the right in quadrant 1. The curve starts at (3, 1) and goes through (4, 2) and (7, 3).
Answer:
3 ≤ x < ∞
Step-by-step explanation:
You want the domain of a square root function shifted right 3 units and up 1 unit. It goes through points (3, 1), (4, 2) and (7, 3).
DomainThe domain of a function is the set of values of the independent variable for which the function is defined. It is the horizontal extent of the graph.
The graph of the given square root function extends to the right from x=3.
The domain is 3 ≤ x < ∞. In interval notation, it is [3, ∞).
Find the equation for the line that passes through the points (-2,-6) and (6,5). Give your answer in point-slope form. You do not need to simplify
The point-slope form of the equation of a line is given by the following expression:
y - y1 = m(x - x1)
Where m is the slope of the line and (x1, y1) is a point where the line passes through.
The slope of the line can be determined with the following formula:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]Where (x1, y1) and (x2, y2) are two points where the line passes through. In this case we are told that the line passes through the points (-2,-6) and (6,5). By replacing the x and y coordinates of these points into the formula of the slope, taking x1 as -2, x2 as 6, y1 as -6 and y2 as 5, we get:
[tex]m=\frac{5-(-6)}{6-(-2)}=\frac{5+6}{6+2}=\frac{11}{8}[/tex]Then, the slope of the line equals 11/8, by replacing 11/8 for m into the slope-point form, we get:
y - y1 = 11/8(x - x1)
By taking one of the points, for example (-2,-6), we replace the x and y-coordinates that appear in the equation of the line, to get:
y - (-6) = 11/8(x - (-2))
y + 6 = 11/8 (x + 2)
Then, the equation of the line in slope-point form is y + 6 = 11/8 (x + 2)
Assume a normal distribution and that the average phone call in a certain town lasted 9 minutes, with a standard deviation of 2 minutes. What percentage of the calls lasted less than 5 minutes?
Given the sample mean of the distribution as 9 minutes.
Also, the sample deviation as 2 minutes;
Given the z-score formula;
[tex]z=\frac{x-\mu}{\sigma}[/tex]Where;
[tex]x=5,\text{ }\mu=9\text{ and }\sigma=2[/tex][tex]\begin{gathered} z=\frac{5-9}{2} \\ z=-\frac{4}{2} \\ z=-2 \end{gathered}[/tex]Now, from the Z-table;

the amount of water a washing machine uses varies directly with the number of loads of laundry washed. if a machine uses 65 gallons of water to wash 5 loads, how much water will be used to was 8 loads?
Let g represent gallons of water and let L represent loads.
Here, the gallons of water varies directly with the number of loads, thus we have:
g ∝ L
Now introduce a constant k:
g = kL
65 gallons is used to wash 5 loads, thus we have:
65 = k * 5
Let's solve for k:
65 = 5k
Divide both sides by 5:
[tex]\begin{gathered} \frac{65}{5}=\frac{5k}{5} \\ \\ 13=k \end{gathered}[/tex]To find the amount of water that will be used to wash 8 loads, we have:
g = kl
We are to find g, substitute 13 for k and 8 for l:
g = 13 x 8
g = 104
Therefore, to wash 8 loads, 104 gallons of water is needed.

You are an executive with the Varsity Corporation in Atlanta, Georgia. The company president was scheduled to make an important sales presentation tomorrow afternoon in Seattle, Washington, but he has now asked you to take his place.
The trip consists of a 2 1/4 hour flight from Atlanta to Dallas, a 1 1/2 hour layover in Dallas, and then a 3 1/2 hour flight to Portland. There is a 1 3/4 hour layover in Portland and then a 3/4 hour flight to Seattle. Seattle is on Pacific Time, which is 3 hours earlier than Eastern Time in Atlanta.
a) If you depart Atlanta tonight at 9:30 p.m. and all flights are on schedule, what time will you arrive in Seattle?
b) If your return flight is scheduled to leave Seattle at 9:10 p.m. tomorrow night, with the same flight times and layovers in reverse, what time are you scheduled to arrive in Atlanta?
c) If the leg from Dallas back to Atlanta is 2/3 of an hour longer than scheduled due to headwinds, what time will you actually arrive?
Using operations with mixed numbers and relations between hours and minutes, it is found that:
a) You will arrive in Seattle at 4:15 am.
b) You will arrive in Atlanta at 9:50 a.m.
c) You will arrive in Atlanta at 10:30 a.m.
How to convert a mixed number to decimal?A mixed number is represented as follows:
a b/c.
In which:
a is the integer part of the number.b/c is the fractional part of the number.As a decimal, the number is given as follows:
a + (b/c).
For item a, it is found that the time it takes to arrive in Seattle from Atlanta is given by the addition of these following numbers:
2.25 hours. (Atlanta to Dallas)1.5 hours. (Layover).3.5 hours (Dallas to Portland).1.75 hours (Layover).0.75 hours (Portland to Seattle).Hence the time in hours is:
2.25 + 1.5 + 3.5 + 1.75 + 0.75 = 9.75 hours = 9 hours and 45 minutes.
Seattle is 3 hours behind Atlanta, hence the time you arrive there is:
6:30 pm + 9 hours and 45 minutes = 4:15 am, as:
6:30 pm is the time in Seattle when you depart Atlanta.30 minutes + 45 minutes = 75 minutes = 1 hour and 15 minutes.9 hours and 45 minutes after 6:30 p.m. is of 4:15 a.m.For item b, we have that:
When the plane leaves Seattle, it is 0:10 am in Atlanta, as it is 3 hours ahead.9 hours and 45 minutes of flight, hence you should arrive in Atlanta at 9:50 a.m.For item c, 2/3 of an hour is 40 minutes, 40 minutes after 9:50 am is 10:30 a.m., which is the time you would arrive.

Julia received an 88, 90, 94, 89 on her first four English quizzes. What must she get on her fifth in order to have a 92 average?
Answer:
99
Step-by-step explanation:
You can set up a proportion, and solve for the variable (missing grade in this case):
[tex]\frac{88+90+94+89+x}{5} =92[/tex]
Each grade is already in the database, so it can serve as the constant, and five is the denominator because to get a mean average, you must divide all the values by the number of values that exist. So, in this case, it would be 5, 4 including the missing grade, making it 5. Set the equation equal to 92, because that's her desired average, then just solve for x.
Multiply the 5 on both sides.
-> 5 cancels on left, and 5 multiplies with 92 to get 460.
[tex](5)\frac{88+90+94+89+x}{5} = 92(5)[/tex]
Add all constants on the left side of the equation.
-> 88+90+94+89=361
[tex]361+x = 460[/tex]
Subtract that new constant (361) from the 460, and you get x=92.
-> 460-361=99
[tex]x=99[/tex]

A line that describes a proportional relationship between x and y is graphed on a coordinate grid. The line passes through (6, 2). Through what other point must the line pass?
The other point through which a line that describes a proportional relationship must pass is the point (0, 0)
What is a proportional relationship?A proportional relationship is one in which each the ratio of the x and y–values of each point on the line of the function is a constant.
The given relationship described by the line = A proportional relationship
The given point on the line = (6, 2)
Required; The other point through which the line must pass.
Given that the relationship described by the line, the ratio of all points on the line is a constant and each point (x, y) can be expressed in the form;

A theme park guest takes an innertube into the wave pool. The innertube moves up and down in a way such that the height h of the innertube, in meters, above the floor of the pool can be modeled by the function h = asinbx + 5. When the wave pool is turned on, the innertube's height fluctuates between 2 meters and 8 meters, with an interval of 12 seconds between maximums. Based on the context of the problem, what are the values of a and b?
So we are told that the height of the innertube in meters is given by:
[tex]h(x)=a\sin (bx)+5[/tex]The minimum height is 2 meters, the maximum is 8 meters and the time between two consecutive maximums is 12 seconds. Here is important to note a few properties of the sine. First of all, the minimum value of sin(bx) is -1 and its maximum value is 1. Then the height of the innertube is minimum when sin(bx)=-1 and maximum when sin(bx)=1. With these two values we can build two equations for a:
[tex]\begin{gathered} \min (h)=2=a\cdot(-1)+5 \\ \max (h)=8=a\cdot1+5 \end{gathered}[/tex]So we have:
[tex]\begin{gathered} 2=-a+5 \\ 8=a+5 \end{gathered}[/tex]Substracting 5 from both sides of the second equation we get:
[tex]\begin{gathered} 8-5=a+5-5 \\ 3=a \end{gathered}[/tex]Using this in the first equation gives us:
[tex]\begin{gathered} 2=-3+5 \\ 2=2 \end{gathered}[/tex]Which confirms that a=3. Now we have to find b. For this purpose we can recal another property of the sine. Its period i.e. the distance (in this case the time) between two consecutive maximums is given by:
[tex]\frac{2\pi}{b}[/tex]Since we know this time is 12 seconds we get:
[tex]\frac{2\pi}{b}=12[/tex]If we multiply both sides by b and divide them by 12 we get:
[tex]\begin{gathered} \frac{2\pi}{b}\cdot\frac{b}{12}=12\cdot\frac{b}{12} \\ \frac{2}{12}\pi=b \\ \frac{\pi}{6}=b \end{gathered}[/tex]So we have:
[tex]a=3\text{ and }b=\frac{\pi}{6}[/tex]Which means that the answer is the second option.
A student bank balance at the beginning of month was $843 during the month she deposits $92’ $404’ $39 and $51 also she made withdrawal of $70 $87 and $221 what was the student’s balance at end of month?
The account balance at the end of the month is $1051.
How is the balance estimated in a bank account?To estimate the balance in a bank account, one has to add the credit to the available balance of the account and subtract the debited amount from the same.
It is given that the account balance initially is $843.
The deposited balances are $92, $404, $39 and $51.
Add the credited amount to the account balance.
So, the current amount is = $843+ $92+ $404+ $39+ $51= $1429
The withdrawal amount is $70, $87 and $221
Subtract the debited amount to the account balance.
So, the current amount is = $1429 - $70 -$87 - $221 = $1051.
So, the account balance at the end of the month is $1051.

Describe a series of transformations Matt can perform to device if the two windows are congruent
Congruent shapes are produced when the three transformations—rotations, reflections, and translations—are combined. Any pair of congruent shapes can actually be matched to one another by combining one or more of these three transformations.
Definition of transformationsAn object's shape and/or location can vary in each of the four possible transformations of a point, line, or geometric figure. Pre-Image refers to the shape of the object before transformation, whereas Image refers to the location and shape of the object after transformation.
Data Presented
We now understand that stiff transformations preserve the size and shape of the figures (reflections, translations, and rotations). The pre-image and the actual image always concur.
The following transformational skills belong to Matt:
Reflection
A reflection maintains its initial form because the Comparable locations from the pre-image to the picture remain at the same distance from the line of reflection.
Rotations as a Congruence Transformation
A rotating figure twists. Despite being the same size and shape as before, the figure appears to have toppled over. A clock is an excellent example of how the globe actually rotates. Every hour or every day, a clock's connecting arms revolve around its axis. The degree of a rotation determines what kind of rotation it is; popular rotations include those of 90, 180, and 270 degrees. Before going back to its original position, the figure rotates a full 360 degrees. the clockwise or counterclockwise direction in which a revolution happens. This data can be used to determine the degree, amount, and a revolution's speed and direction.
Congruence translational transformation
When an object or shape is transferred from one location to another without altering its size, shape, or orientation, we refer to the transfer as a movement. A translation, often known as a slide, involves moving every point on an object or shape uniformly and in one direction.
