The Taft Public Library is a library built in the shape of a square. The checkout desk is located in the center of the building. You have been asked to help make a map of the library, using a coordinate plane. Since the library is 100 feet on each edge, you have decided to use a coordinate plane from -10 to 10 on each axis. Each unit represents 5 feet. The y-axis runs north-south, and the x-axis runs east-west.

Answer:
96 inches squared or [tex]96in^{2}[/tex]
Step-by-step explanation:
So I'm assuming that the figure shown is the fragment that is left because it doesn't exactly say what it is.
The area of a rectangle is length times width, so to the area of the original manuscript is....
A=lw
A=20(12)
A=240
You get 20 from the question and 12 from the figure.
Next, you should find the area of the fragment that is left. I would split it up into two shapes, a triangle and recitable, since right now it's a weird looking shape. The area of a triangle is base time height divided by 2....
A=[tex]\frac{bh}{2}[/tex]
The base is 12 because 18-6=6 and the height is 12 because is the width of the original rectangle. (I suggest making a line in between fragment to spilt it into two shapes or even re-drawing it to see it more clearly.) Therefore plugging everything into the equation....
A=[tex]\frac{12(12)}{2}[/tex]
A=[tex]\frac{144}{2}[/tex]
A=72
Now to find the area of the rectangle of the fragment that is left over, use the the same equation from above that was used to find the area of a rectangle and just plug in the numbers 12 and 6 because you can use the number on the top and the number on the side of the figure
A=12(6)
A=72
The final step is to subtract the area of the smaller rectangle and triangle from the original manuscript
240-72-72=96
Therefore the answer is [tex]96in^{2}[/tex]. Hope this helps. : )

What are the measures of ∠ADC and ∠DCB in the figure?
Answer:
measure of angle ADC = 100°
measure of angle DCB = 39°
Step-by-step explanation:
We know that all the interior angles of a triangle add up to equal 180°, so we can set up an equation based on what we know from the figure (Angle C is the sum of [tex](4x-1)[/tex]° and [tex](2x+17)[/tex]°):
180° = 43° + 61° + [[tex](4x-1)[/tex]° + [tex](2x+17)[/tex]°]
180° = 43° + 61° + [tex]6x +16[/tex]°
180° = 104° + 16° + [tex]6x[/tex]
180° = 120° + [tex]6x[/tex]
60° = [tex]6x[/tex]
10° = [tex]x[/tex]
Now that we know the value of [tex]x[/tex], we can easily plug in 10° for [tex]x[/tex] in the angles we need to find.
The second angle we need to find uses [tex]x[/tex], so we can now find it. Angle DCB is, according to the figure, equal to [tex]4x-1[/tex].
[tex]4x-1[/tex]
[tex]4(10)-1\\40-1\\39[/tex]
Thus, the measure of angle DCB is equal to 39°.
However, angle ADC is defined in terms of [tex]y[/tex], so we'll have to find the value of [tex]y[/tex]. This is easy, however, because the two angles using [tex]y[/tex] meet together to form a straight line. Since we know that a straight line has an angle measure of 180°, we can once again set our equation equal to 180°.
180° = [tex](3y+7)+(3y-13)[/tex]
180° = [tex]6y[/tex] + 7° - 13°
180° = [tex]6y[/tex] - 6°
186° = [tex]6y[/tex]
31° = [tex]y[/tex]
Now, we'll simply substitute 31° for [tex]y[/tex] in the measure of angle ADC:
[tex]3y+7\\3(31)+7\\93+7\\100[/tex]
Therefore, the measure of angle ADC is equal to 100°.
The measure of <ADC is 100 Degree and measure of <DCB is 39 Degree.
What is Angle Sum Property?The angle sum property of a triangle states that the sum of the angles of a triangle is equal to 180º.
Given:
First, (3y+ 7) + (3y - 13) = 180 (Linear Pair)
6y - 6 = 180
6y = 186
y = 31
So, measure of <ADC = 3y+ 7 = 3(31)+ 7 = 93 + 7 = 100 Degree
In Triangle ADC, using Angle Sum property
3y -13 + 61 + 4x - 1 = 180
93 - 13 + 61 - 1 + 4x = 180
4x = 40
x= 10
So, the measure of <DCB = 4x-1 = 4(10)-1 = 39 Degree.

For the second one, I chose 3/5 because there are 3 friends whose names end in a, and 5 friends whose names do not end in a. My theory was that I took the friends and divided them into 2 groups by most common.

It costs $5 per hour to rent a snowboard from a certain ski rental company, plus a $50 deposit. Another ski rental company charges $10 per hour to rent a snowboard, plus a $25 deposit. For what number of hours is the cost to rent a snowboard the same at each company? What is the cost of renting a snowboard for this number of hours
The number of 5 hours is the cost to rent a snowboard the same for each company.
And the cost is $75.
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
Given:
It costs $5 per hour to rent a snowboard from a certain ski rental company, plus a $50 deposit.
Let n be the number of hours.
So, 5n + 50.
Another ski rental company charges $10 per hour to rent a snowboard, plus a $25 deposit.
10n + 25
When the cost is equal,
5n + 50 = 10n + 25
5n = 25
n = 5
And the cost is $75.
Therefore, all the required values are given above.

A student attempted to generate an equivalent expression using the distributive property, as shown below: 5(x − 1) = 5x − 1 What was the mistake made? (1 point) 5 was not multiplied by x Incorrect sign was used for the first term 5 was not multiplied by −1 Incorrect sign was used for the second term
Answer:
the correct answer must be 5x - 5 not 5x - 1
Step-by-step explanation:
when we have a question such as 5(x - 1)
we must multiply both the numbers by 5
so we get 5 X x and 5 X -1
so it will be 5x - 5 which is the answer.

Sum of two odd numbers will always be even.
Sum of two even numbers will always be even.
Sum of one odd and one even number will always be odd.
Let the both numbers be first and second.
According to the problem statement:
first + second = 19
first – second = 5
Add both equations:
first + second + first – second = 19 + 5
2 * first = 24
first = 24 / 2
first = 12
So from this we get first = 12, put this value in any equation i.e.
first + second = 19 (Put the value of first in this equation)
12+ second = 19
second = 19 – 12
second = 7
So, the numbers are 12 and 7.

Answer:
68% 32%
73.5% 26.5%
Step-by-step explanation:
Start:
total number = 561 + 264 = 825
glucose aversion = 561
percent = 561/825 × 100% = 68%
no glucose aversion: 264
percent = 264/825 × 100% = 32%
End:
total number = 441 + 159 = 600
glucose aversion = 441
percent = 441/600 × 100% = 73.5%
no glucose aversion: 159
percent = 159/600 × 100% = 26.5%
