================================================
Explanation:
Let's go through the answer choices one at a time.
A) The AA postulate is only used for similar triangles, and not congruent triangles. We need information about at least one pair of sides. Using the angles only isn't enough. We can rule out choice A.B) The HL postulate only applies to right triangles. These triangles are acute triangles, so we can rule out choice B.C) This is the answer as we can rule out choice D, so this is the only thing left. Also, if we know that angle A = angle A'' and angle B = angle B'', then we could use the ASA theorem to prove the triangles congruent.D) This is not a valid congruence theorem. This is because we could have ambiguous cases that arise and lead to confusion. Also, it is possible that if we know two sides and a non-included angle, then a triangle may not be able to be formed. It will depend on the angle and side values. Therefore, we can rule out choice D.4.x = 28

I think the answer is Z is 45 degrees
hope this helps!
Answer:
The value of tangent Z is
[tex] \frac{3}{4} [/tex]
Note that the question asks for the value of tan z NOT angle z.
Step-by-step explanation:
[tex] \tan(z) = \frac{opposite}{adjacent} = \frac{21}{28} = \frac{7 \times 3}{7 \times 4} = \frac{3}{4} [/tex]

A school has 840 pupils, if the school hall has seats 85% of the pupils, how many pupils will have no seats?
Answer:
126
Step-by-step explanation:
So theres 840 people and 85% got a seat
We just do 840 * 85% = 714
then to find the people without the seat
840 - 714 = 126

A coach throws a football from a height of 4 feet with an initial velocity of 59 feet per second at an elevation angle of 45 degrees. Which parametric equation represents the path of the football
Answer:
[tex]x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2[/tex]
Step-by-step explanation:
From the question we are told that
Height [tex]h=4feet[/tex]
Initial velocity of[tex]v_0=59 feet/sec[/tex]
Angle [tex]\theta= 40\textdegree[/tex]
Generally the parametric equation for projectile motion is mathematically given by
[tex]x=(v_0cos\theta)t,y=y_0+(v_0sin\theta)t-16t^2[/tex]
Therefore
[tex]x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2[/tex]
The parametric equation that represents the path of the football
[tex]x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2[/tex]

like to have some leftovers. I've discovered that the proper ratio of turkey to people is 12 pounds of turkey for every 8 people. If 36 people are going to be eating, how many pounds of | turkey do I need to buy?
Answer:
A
Step-by-step explanation:
Took the test
There is a need for 58.5 pounds of turkey for 36 people.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
The proper ratio of turkey to people is 12 pounds of turkey for every 8 people.
Let the number of pounds would be x for 36 people
According to the given situation, we can write the ratio would be as:
12 pounds of turkey : 8 people = x pounds of turkey : 36 people
⇒ 12 / 8 = x / 36
Apply the cross-multiplication operation,
⇒ 8x = 13 × 36
Apply the multiplication operation,
⇒ 8x = 468
⇒ x = 468/8
Apply the division operation,
⇒ x = 58.5
Therefore, there is a need for 58.5 pounds of turkey for 36 people.

Which equation best represents the line? (4 points)
Oy - 3x - 1
Oy - 3x + 1
Answer:
The equation best represents the line is:
y = 3x-1Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptTaking the two points
(0, -1)(1, 2)Determining the slope between the points (0, -1) and (1, 2)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:-1\right),\:\left(x_2,\:y_2\right)=\left(1,\:2\right)[/tex]
[tex]m=\frac{2-\left(-1\right)}{1-0}[/tex]
Refine
[tex]m=3[/tex]
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
As we are given the point (0, -1)
It means at x = 0, y = -1
Thus, the y-intercept b = -1
now substituting b = -1 and m = 3 in the slope-intercept form
y = mx+b
y = 3x + (-1)
y = 3x-1
Therefore, the equation best represents the line is:
y = 3x-1Which math expression means "the sum of 33 and 18"? O A. 33 = 18 O B. 33. 18 O C. 33 - 18 O D. 33 + 18
Answer:
D. 33 + 18
Step-by-step explanation:
Sum in mathematics is the same as addition or plus.
As such the sum of two or more numbers is the addition of these numbers or the result obtained when the plus sign is placed in between the given numbers.
Hence, the sum of 33 and 18 may be expressed as
33 + 18

Brandi rolls a fair Six-sided Number cube flips a fair coin, and then rolls the number cube again. Which outcome is part of sample space?
Answer:
Options aren't given but explanation and answer is below:
Step-by-step explanation:
First action/trial - Rolling a fair dice (6-sided number cube)
Second action - Flipping a fair coin
Third action - Rolling a fair dice
In this experiment, all the equipment are fair. What this means is that there is no bias; every face of each equipment has an equal chance of emerging tops.
In your options, you should have three values per option.
The first would be the number resulting from the first throw of dice.
The second would be head or tail; which are the only two faces of a coin.
The third would be the number resulting from the second throw of dice.
So ONE of those options will be a part of the sample space, which is enlisted below:
Trial A: {1, 2, 3, 4, 5, 6}
Trial B: {Head, Tail}
Trial C: {1, 2, 3, 4, 5, 6}
* If there's an option like {9, Tail, 2} it will be wrong, because it has an element "9" which does not fall within the prescribed sample space.
* Also, if we follow the order in which Brandi conducted this experiment, an option like {Head, 6, 5} will be wrong, since the elements are wrongly placed.
Michael's High School is selling tickets to its spring musical. On the first day of ticket sales the school sold 1 adult ticket and 3 student tickets for a total of $38. The second day of sales, the school sold 5 adult tickets and 1 student ticket for a total of $78
Write a system of equations to represent the number of tickets sold each day
Determine the price of an adult ticket and a student ticket
Answer:
adult ticket price: $14
student ticket price: $8
Step-by-step explanation:
x = adult ticket
y = student ticket
system equations:
[tex]x + 3y = 38 \\ 5x + y = 78[/tex]
elimination method:[tex]x + 3y = 38 |multiple \: by \: 1\\ 5x + y = 78|multiple \: by \: 3 \\ \\ x + 3y = 38 \\ 15x + 3y = 234 \\ subract \: them: \\ - 14x = - 196[/tex]
substitute:[tex] - 14x = - 196 \\ - x = \frac{ - 196}{14} \\ - x = - 14 \\ x = 14[/tex]
find the y using substitution method:
x+3y=38
14+3y=38
3y=24
y=24/3
y=8
so the price of an adult ticket is $14 and the price of student ticket is $3

What is the reason that absolute value is always written as a positive?
Absolute Value is talking about numbers so it must be positive
Absolute Value is like a clock it has only positive numbers
Absolute value does not always have to be positive
Absolute value is talking about distance (Distance from zero); distance is always
measured by positive numbers.
Answer:
Absolute value is talking about distance (Distance from zero); distance is always measured by positive numbers.
