Write the missing partial products in the area model Then, write the partial to complete the equation below. Find the sum
The missing partial products are:
10 x 2 = 20
6 x 50 = 300
6 x 2 = 12
The sum of the partial products is,
16 x 52 = 500 + 300 + 20 + 12 = 832
Here the partial products method is used to find the product of two two digit numbers 16 and 52.
For this a table of the form given in the figure is constructed in which the partial products are found.
For this first split 16 and 52 into 10 + 6 = 16 and 50 + 2 = 52.
Then take the partial products between 10 and 50, 10 and 2, 6 and 50, 6 and 2. Then take the sum of all these four values to get the final answer. This is the method of partial products.
So finding the partial products,
10 x 50 = 500
10 x 2 = 20
6 x 50 = 300
6 x 2 = 12
To find the final answer, take the sum of these products.
500 + 300 + 20 + 12 = 832
⇒ 16 x 52 = 832

Dealership B has produced the following graph to show that their customers are more satisfied than the customers of two of their competitors. Which statement best describes why the graph is misleading?
A horizontal bar graph titled 'Car Dealership Satisfaction Rating' is shown.
Three bars of data are represented on the graph. The horizontal axis shows a short distance to 70 percent from the left, a longer distance to 80 percent, an equal distance to 90 percent, and another equal distance to the unlabeled end of the axis.
· The first bar is labeled 'Dealership upper A' and extends horizontally to less than half way between 80 percent and 90 percent.
· The second bar is labeled 'Dealership upper B' and extends horizontally to less than half way between 90 percent and the end of the graph.
· The third bar is labeled 'Dealership upper C' and extends horizontally to more than halfway between 80 percent and 90 percent.
A. It is difficult to determine the actual satisfaction levels for each car dealership, so a clear comparison cannot be made.
B. Using percentages makes it seem like there is a large difference in customer satisfaction between Dealership B and its competitors.
C. Not enough car dealerships were included in the survey.
D. Dealership B’s customer satisfaction looks better than it really is because the graph does not start at zero.

A magician is training for an underwater escape trick. Using a new technique, he can hold his breath for 144 seconds. That is 60% more than he was able to do when he first tried. How long could the magician hold his breath when he first tried?
The number of seconds that the magician hold his breath when he first tried is 90 seconds.
How to calculate the value?With the new technique, he can hold his breath for 144 seconds and that is 60 percent more than he was able to do when he first tried.
Let the number of seconds for the first try be represented by x. Therefore, based on the information, this will be illustrated as:
= x + (60% × x) = 144
x + 0.6x = 144
1.6x = 144
Divide
x = 144 / 1.6
x = 90

Find f(g(x)) and g(f(x)) and determine whether the pair of functions f and g are inverses of each other.
f(x)=6x+5 and g(x)= x-5/6
a. f(g(x))= (Simplify your answer.)
b. g(f(x))= (Simplify your answer.)
Step-by-step explanation:
a. f(x) = 6x+5 and g(x) = x--5/6
f(g(x)) = 6x + 5
Now, let x = g(x) (remember f(x) = 6x+5 so we got the x from f(x))
f(g(x)) = 6(x--5/6) + 5
Open bracket
f(g(x)) = 6(x -- 5/6) + 5
f(g(x)) = x -- 5 + 5
f(g(x) = x
b. g(f(x) = x--5/6
g(f(x) = (6x+5) -- 5/6
g(f(x)) = 6x + 5 -- 5/6
g(f(x)) = 6x/6
g(f(x)) = x...
To check for inverse
1/g(f(x) = 1/x
1/f(g(x) = 1/x
Meaning 1/f(g(x) = 1/g(f(x) inverse of each other

Time Conversions: Convert to the asked time.
. 8 hours, 20 minutes, and 36 seconds =
hours
The answer in hours is 8.91 hours.
How do you convert minutes and seconds to hours?Converting between hours, minutes, and seconds using decimal time is relatively straightforward: time in seconds = time in minutes * 60 = time in hours * 3600. time in minutes = time in seconds / 60 = time in hours * 60. time in hours = time in minutes / 60 = time in seconds / 3600.
Given: 8 hours 20 minutes and 36 seconds
20 minutes in hours can be written as 20 / 60 = 1/3 hours or 0.9 hours
because as mentioned above 1 hour = 60 min
and 36 seconds in hours can be written as 36/ 60X60 = 1/ 100 hours or 0.01 hours .
because 1 min = 60 seconds and 1 hour = 60 min
thus 1 hour = 60 X 60 seconds
Thus the final answer is 8+0.9+0.01 hours = 8.91 hours

[tex]\textsf{2. \quad Solution: $-2 < x < 4$,\quad Interval notation: $(-2, 4)$}[/tex]
Step-by-step explanation:
Question 1The intervals on which a quadratic function is positive are those intervals where the function is above the x-axis, i.e. where y > 0.
The zeros of the quadratic function are the points at which the parabola crosses the x-axis.
As the given quadratic function has a negative leading coefficient, the parabola opens downwards. Therefore, the interval on which y > 0 is between the zeros.
To find the zeros of the given quadratic function, substitute y = 0 and factor:
[tex]\begin{aligned}y&= 0\\\implies -7x^2+35x-28& = 0\\-7(x^2-5x+4)& = 0\\x^2-5x+4& = 0\\x^2-x-4x+4& = 0\\x(x-1)-4(x-1)&= 0\\(x-1)(x-4)& = 0\end{aligned}[/tex]
Apply the zero-product property:
[tex]\implies x-1=0 \implies x=1[/tex]
[tex]\implies x-4=0 \implies x=4[/tex]
Therefore, the interval on which the function is positive is:
Solution: 1 < x < 4Interval notation: (1, 4)Question 2The intervals on which a quadratic function is negative are those intervals where the function is below the x-axis, i.e. where y < 0.
The zeros of the quadratic function are the points at which the parabola crosses the x-axis.
As the given quadratic function has a positive leading coefficient, the parabola opens upwards. Therefore, the interval on which y < 0 is between the zeros.
To find the zeros of the given quadratic function, substitute y = 0 and factor:
[tex]\begin{aligned}y&= 0\\\implies 2x^2-4x-16& = 0\\2(x^2-2x-8)& = 0\\x^2-2x-8& = 0\\x^2-4x+2-8& = 0\\x(x-4)+2(x-4)&= 0\\(x+2)(x-4)& = 0\end{aligned}[/tex]
Apply the zero-product property:
[tex]\implies x+2=0 \implies x=-2[/tex]
[tex]\implies x-4=0 \implies x=4[/tex]
Therefore, the interval on which the function is negative is:

Martin Binford is an author. He has no income he would report on line 1a or line 1b of his schedule SE. He earned $143,380 in 2010 from his books. He had $3,563 in expense. How much self-employment tax does he owe?
Answer:
He owes $33556.08 worth of self employment tax.
Explanation:
consider firstly calculating the profit that he has made after this period which can be calculated as profit= income minus expenses and in this case we are given income earned from self employment of $143380 and the expenses incurred in generating this income is $3563 so we find he difference in these two amounts which is $143380-$3563 = $139817 therefore this profit is the taxable income that he needs to deduct tax from.
in order to calculate tax from this amount we go to the tax table so therefore a person earning between $84201 to $160725 is charged 24% tax as per tax table. so now we will say $139817 x 24% = $33556.08 is the tax he owes the IRS.

The true statement is option A, They show that the equation represents the same line.
Given,
Two equations:
Equation A : 4y - 3x = 4
Equation B : -2x - 8y = 8
These lines intersect at a single point (-2, -0.5)
We have to find the true statement which satisfies the values x as -2 and y as -0.5.
Lets check
x = -2
y = - 0.5
Equation A:
4y - 3x = 4
4 × (-0.5) - 3 × (-2)
= -2 - (-6)
= - 2 + 6
