Define fraction.The numerical numbers that make up a fraction of the whole are called fractions. A whole can be a single item or a collection of items. When anything or a number is divided into equal parts, each piece represents a portion of the total. A fraction is represented as a/b, where a and b are the numerator and denominator, respectively. A fraction only informs us of the number of parts that make up the whole. The slash that is inserted between the two numbers identifies a fraction. The numerator is the highest number, and the denominator is the lowest number. [tex]\frac{1}{2}[/tex], for instance, is a fraction.
Given Data
In a work survey, it was found that:
28 employees preferred tea
45 employees preferred coffee
32 didn't like either
a) Number of employees that prefer coffee
= 45
Fraction:
= [tex]\frac{45}{105}[/tex]
= [tex]\frac{3}{7}[/tex]
b) Percentage of employees don't like either tea or coffee

we will solve as follows:
[tex](21x^2+13x-9)-(17x^2-6x+12)=4x^2+19x-21[/tex]On one day Fred’s Sports World sold 9 Buffalo Bills jerseys and 3 Miami Dolphin jerseys for a total of $899.40. The next day they sold 12 Bills jerseys and only 2 Dolphins jerseys for a total of $1139.30. How much is the Bills jersey and how much is the Dolphins jersey?
Given:
Let x be the cost of the Buffalo Bills jersey.
Let y be the cost of the Miami Dolphin jersey.
According to the question, we have
9x+3y=899.40.......(1)
12x+2y=1139.30.....(2)
From (1),
[tex]\begin{gathered} 3y=899.40-9x \\ y=299.8-3x\ldots\ldots(3) \end{gathered}[/tex]Substitute equation (3) in equation (2), we get

Let o be the point of intersection of the diagonals of a quadrilateral abcd. prove that abcd could be a trapezoid (that is, it has one pair of opposite sides parallel) if aaod=aboc
Given the details above, the sequence of steps below shows that ABCD is a Trapezoid.
What is a Trapezoid?A trapezoid, also known as a trapezium, is a closed, flat object with four straight sides and one set of parallel sides. A trapezium's parallel sides are known as the bases, while its non-parallel sides are known as the legs.
Given:
The diagonals of the quadrilateral ABCD intersect at o where AO/BO = CO/DO; which also means that
AO/CO = BO/DO the proof is given as follows:
Create line OE || DC in a way that E lies on BC.
In ΔBDC, based on the Basic Proportionality Theory,
BO/OD = BE/EC ............................1
It is also given that:
AO/CO = BO/DO ..........................2
Hence, from Equations 1 and 2,
AO/CO = BE/EC
Thus, we can state that on the basis of the Converse of the Basic Proportionality Theorem,
OE || AB
Since AB || OE || DC, it is correct to state that ABCD is a Trapezoid.

Graph 1 contains the two angles in the domain 0 ≤ θ ≤ 360º that have cosine given by cos(θ) = -3/5.
Where is the cosine of angle negative?The sine and the cosine of an angle are represented in the unit circle, in which:
The x-axis is composed by the cosine of the angle.The y-axis is composed by the sine of the angle.Hence the cosine of the angle is negative when the x-axis is negative, which happens in these following quadrants:
Second quadrant.Third quadrant.The only equation that can be solved in the context of this problem is:
cos(θ) = -3/5.
The solution is composed by two angles, one in the second quadrant and one in the third quadrant, hence Graph 1 shows the correct solution.

A tent pole that is 9 feet tall is secured to the ground with a piece of rope that is 15 feet long from the top of the tent pole to the ground. Determine the number of feet from the tent pole to the rope along the ground.
Answer:
12 ft
Step-by-step explanation:
To find the base (b), you would first need to sketch a right triangle using the following:
a = 9
c = 15
Using the Pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex], you would change it to [tex]c^{2} -a^{2} =b^{2}[/tex] to fit the question. Next, you would plug in the numbers to the corresponding letter.
[tex]15^{2} -9^{2} =b^{2}[/tex]
[tex]225-81=144^{2}[/tex]
[tex]\sqrt{144} =b[/tex]
[tex]12=b[/tex]
The horizontal distance from the tent pole to the rope along the ground will be equal to 12 feet.
What is the Pythagoras' Theorem?According to the Pythagoras theorem, if a triangle has a straight angle (90 degrees), the hypotenuse's square is equal to the total of its other two sides' squares.
As per the given in the question,
Height of tent pole, p = 9 feet
Height of rope, h = 15 feet
Let the horizontal distance from pole to rope is b.
Use Pythagoras' theorem,
h² = p² + b²
15² = 9² + b²
b² = 225- 81
b = √144

1 kg = 2.20462
With the above scale, we can convert each measurement to pound as follow:
I. Brown bear
1 kg = 2.20462
Therefore,
272.16 Kg = 272.16 × 2.20462
272.16 Kg = 600 pounds

b. Olivia can withdraw can withdraw money from her account money for approx. 13 weeks.
Let x represent the number of weeks. Then the amount of withdrawal in this time is 40x
So, the amount remaining in the account after x weeks is 700 - 40x
Since he needs 150$ in the account for safety net, we must have

8x + 16 = 360
8x = 344
x = 344/8 = 43°
