Answer:
40 14/25 years
Step-by-step explanation:
Well, this certainly is fun.
First, to find the fraction of the doctor's life which 13 years represents, subtract the fractions from 1 (and in this case l stands for lifetime):
[tex]13 = (1 - (\frac{1}{13} + \frac{4}{39} + \frac{1}{2}))(l)[/tex]
[tex]13 = (\frac{25}{78})(l)[/tex]
So, multiply this equation by the reciprocal of 25/78 to isolate one of l:
[tex]13(\frac{78}{25}) = l[/tex]
[tex]l = 40\frac{14}{25}[/tex] years
Find the value of the variables in each figure. Explain your reasoning.
Answer:
see explanation
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
Each lower base angle is supplementary to the upper base angle on the same side, thus
15x + 30 + 10x = 180 , that is
25x + 30 = 180 ( subtract 30 from both sides )
25x = 150 ( divide both sides by 25 )
x = 6
Also
3y + 18 + 90 = 180 , that is
3y + 108 = 180 ( subtract 108 from both sides )
3y = 72 ( divide both sides by 3 )
y = 24
-------------------------------------------------------------------
2x, 90 and x lie on a straight line and sum to 180 , thus
2x + 90 + x = 180 , that is
3x + 90 = 180 ( subtract 90 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
------------
2y and x are alternate angles and congruent , thus
2y = x = 30 ( divide both sides by 2 )
y = 15

Select the correct answer from each drop-down menu. Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the , followed by a reflection across the line . Reset Next
Answer:
The sequence of transformations involved is a reflection across the x axis, followed by a reflection across the y = x line
Step-by-step explanation:
The polygon ABCD is shown in the image attached. The coordinates of the polygon are A(-6, 6), B(-4, 6), C(-4, 4), D(-6, 2), while the polygon A'B'C'D' is at A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)
A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.
If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y).
If a point O(x, y) is reflected across the y = x line, the new coordinate is O'(y, x)
Hence if polygon ABCD is reflected across the x axis, the new coordinates are A*(-6, -6), B*(-4, -6), C*(-4, -4), D*(-6, -2). If a reflection across the y = x line, the new coordinates are A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)
Answer:
Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the y-axisy = -x, followed by a reflection across the line y = xy = -x.

What is a reflection across or over the x-axis?In Mathematics, a reflection across or over the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would either change from positive to negative or negative to positive.
This ultimately implies that, a reflection across the x-axis is given by this transformation rule: (x, y) → (x, -y).
By applying a reflection across or over the x-axis to the function, we have the following;
f(x) = -|x|
-f(x)' = |x|
f(x)' = -|x|
Next, we would translate the function to the right by 1 unit as follows;
f(x)' = -|x - 1|

The wholesale price for a bookcase is $105. A certain furniture store marks up the wholesale price by 28% Find the price of the bookcase in the furniture store.
Round your answer to the nearest cent, as necessary.
Answer:
$134.40
Step-by-step explanation:
The markup is 28% of 105, or .28(105) = $29.40
Thus the retail price is $105 + $29.40 = $134.40
The price of the bookcase in the furniture store, after a 28% markup on the wholesale price, is $134.40.
To find the price of the bookcase in the furniture store after a 28% markup on the wholesale price, we need to add the markup amount to the wholesale price.
The markup amount is calculated by multiplying the wholesale price by the markup percentage (expressed as a decimal). In this case, the markup percentage is 28%, which is equivalent to 0.28 as a decimal.
Markup amount = Wholesale price * Markup percentage
Markup amount = $105 * 0.28
Markup amount = $29.40
Now, to find the price of the bookcase in the furniture store, we add the markup amount to the wholesale price:
Price in the furniture store = Wholesale price + Markup amount
Price in the furniture store = $105 + $29.40
Price in the furniture store = $134.40

Shaun keeps his baseball card collection in an album. The album has 25 pages, and each page can hold 9 cards. Four pages are empty, and the rest are full. Write an equation that can be used to determine the number of baseball cards b in Shaun's collection.
Answer:
25x5-4=b
Step-by-step explanation:
The equation to determine the number of baseball cards in Shaun's collection is b = (25 - 4) × 9
Number of pages in the album = 25 pages
Number of empty pages = 4
Number of full pages = 25 pages - 4 pages = 21 pages.
Number of cards that each page can hold = 9 cards.
Therefore, the equation to determine the number of baseball cards in Shaun's collection will be:
b = (25 - 4) × 9
b = 21 × 9
b = 189 cards.
There are 189 cards in the collection.

Answer:
4 Hours and 32 minutes
Step-by-step explanation:
Let's first find the amount between 9:15 to 2:17
The difference between 9:00 and 2: 00 is 5 Hours
Now the minutes -> 17-15 = 2
Thus, the difference is 5 Hour and 2 Minutes
Then She took a 30 minutes break for lunch.
Let's convent all to minutes:
1 Hour = 60
Then 60 x 5 = 300
Plus the 2 minutes is
302
Now 302 minutes - 30 minutes = 272 minutes
Now convent back to Hour
Thus, 272/60 =4 with a remainder of 32.
Hence, it took stephanie 4 hour and 32 minutes to finish her SOL test.
