Which dimensions can create only one unique triangle?
A.) 3 angles measuring 75 degrees, 45 degrees, and 50 degrees
B.) 3 sides measuring 14 m, 11 m, and 18 m
C.) 3 angles measuring 40 degrees, 50 degrees, and 60 degrees
D.) 3 sides measuring 3 cm, 4 cm, and 8 cm
Answer:
B)
Step-by-step explanation:
A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.
Answer: Choice B)
3 sides measuring 14 m, 11 m, and 18 m
=================================================
Explanation:
Let's go through choices A through D to see which result in one unique triangle, or could produce (infinitely) many triangles, or produce no triangles at all.
Choice A produces no triangles at all. Why is this? The angles don't add up to 180. We see that 75+45+50 = 170. The three angles must add to 180 degrees for a triangle to form. Choice B produces one single triangle, which is why it's the final answer. The triangle inequality theorem can be used here to show that a triangle can be formed. The SSS (side side side) congruence theorem is then used to show that exactly one unique triangle is possible. Choice C is a similar story to choice A. We can rule it out. This time we have the angles add to 40+50+60 = 150 which is short of 180.Choice D can be ruled out too. The two sides a = 3 and b = 4 add to a+b = 3+4 = 7, but that's smaller than c = 8. We must have a+b > c to be true if we wanted to form a triangle. For more info, see the triangle inequality theorem.Even if the angles did add to 180 (for either choice A or choice C), then we'd have infinitely many triangles and not one unique triangle. Think of dilating the triangles and how each dilated image retains the same angles. In other words, the triangles keep the same shape. Simply knowing the three angles is not enough info to create one unique triangle. We would need to know some info about the sides. This explains why AA or AAA is not a congruence theorem.

'To help built a playground, people could buy a brick with their name on it for $96. A total of $9,602 was raised, but 25 people donated an extra $50 each. How many people donated only $96?"
Answer: 87 people
Step-by-step explanation:
9,602 = 96x + 25(50)
9,602 = 96x + 1250
9,602 - 1250 = 8352
8352 ÷ 96 = 87
Tyler’s class played the block game using purple, orange, and yellow bags of blocks.
- During round 1, Tyler’s group picked 4 purple blocks and 12 blocks of other colors.
- During round 2, Tyler’s group picked 11 orange blocks and 5 blocks of other colors.
- During round 3, Tyler forgot to record how many yellow blocks his group picked.
For a final round, Tyler’s group can pick one block from any of the three bags. Tyler’s group decides that picking from the orange bag would give them the best chance of winning, and that picking from the purple bag would give them the worst chance of winning. What results from the yellow bag could have lead Tyler’s group to this conclusion? Explain your reasoning.

traveled was proportional to the time he spent driving. After five hours, Geoffrey had driven 340
miles. Determine the constant of proportionality and explain its meaning in the context of this
situation.
7. The perimeter of a square is proportional to the length of its sides. This relationship can be
expressed by the equation P = 4s. What is the constant of proportionality and what does it mean?
Answer:
1. 68 miles per hour. It means he set his cruise control to 68MPH.
2. 4. It means that the perimeter of the square is the 4 sides and each side's length is the same.

A student five and a half feet tall stands opposite of a mirror from a flagpole. The distance between the student and the mirror is 6 feet and the distance from the mirror to the flagpole is 14 feet. What is the height of the flagpole?
Answer:
4√10 = 12.649110640674 ft
Step-by-step explanation:
Given b=6 and c=14,
a^2 + b^2=c^2
a^2 + 6^2 = 14 ^2
a^2 + 36 = 196
a^2 = 160
a= √160
a = 4√10

For any right triangle, the side lengths of the triangle can be put in the equation a2 + b2 = c2 where a, b, and c are the side lengths. A triangle with the side lengths 3 inches, 4 inches, and 5 inches is a right triangle. Which way(s) can you substitute the values into the equation to make it true? Which variable has to match the longest side length? Why?
Answer:
Pythagorean theorem:
a² + b² = c²
a is the long leg of the triangle
b is the short leg of the triangle
c is the hypotenuse
side lengths ; 3 inches, 4 inches, 5 inches of a right triangle.
a = 4 inches
b = 3 inches
c = 5 inches
4² + 3² = 5²
16 + 9 = 25
25 = 25

Answer:
x = 5
Step-by-step explanation:
6*(2x+8) = 108
12x + 48 = 108
x =60/12
x = 5
Answer:
x = 5 units
Step-by-step explanation:
The area of a rectangle equals length times widths, therefore we can use the information from the question to make the following equation...
108 = (2x + 8)(6)
Now we just solve the equation and get...
108 = (2x + 8)(6)
108 = 12x + 48
12x = 108 - 48
12x = 60
x = 60 / 12
x = 5
Therefore, x = 5 units.
Jackson Middle School has 5 students in choir for every 1 student in band. If there are 47 students in band, how many students are in choir?
Step-by-step explanation:
5 students in choir <=> 1 student in band
If there are 47 students in band =>
47×5 = 235 students in choir (B)
Answer:
235 (Option B)
Step-by-step explanation:
GIVEN :-
There are 5 students in a choir for every 1 student in band.TO FIND :-
Number of students in choir if there are 47 students in band.SOLUTION :-
[tex]\boxed {Use \: \: unitary \: \: method \: \: to \: \:solve \: \: this \: \: question}[/tex]
5 students in choir ⇔ 1 student in band. It can be also written as :-
⇒ 1 student in band ⇔ 5 students in choir
Now , multiply 47 to both sides.⇒ (1 × 47) students in band ⇔ (5 × 47) students in choir
⇒ 47 students in band ⇔ 235 students in choir.
CONCLUSION :-
There are 235 students in the choir.

What is parabola equation intercept form?The intercept form of parabola can be expressed using the following expression.
[tex]f(x)=a(x-p)(x-q)[/tex]
Here, a is the constant, (p, q) are the x-values on the graph, where y is zero.
In the given graph, the point (-2,0) is the point, where the value y is zero. Here, the value of x is -2. Therefore,
[tex]p=-2[/tex]
The other point, where the value of y is zero is (5,0). Thus the value of q is,
[tex]q=5[/tex]
The value of constant a is,
[tex]a=-\dfrac{p}{q}\\a=-\dfrac{-2}{5}\\a=0.4[/tex]
Put these values in the above equation, we get,

Sofia is a helper for the kindergarten class and is in charge of picking a video for their end-of-year party. To choose which type of movie they would like best, she decided to survey every other child entering a matinee for a cartoon called, “Three Pretty Princesses.” The total number of children surveyed was 40. What is wrong with the way she selected her sample? Check all that apply.
The sample of 40 children is too small to represent all kindergartners.
The sample was taken at a specific movie, which will skew data towards that type of movie.
The sample is likely to include a lot more girls than boys, since the movie title is “Three Pretty Princesses.”
The sample should include the adults with the children instead of only children.
The sample should include the other peer helpers in her grade to include a greater age range.
Answer:The sample was taken at a specific movie, which will skew the data towards that type of movie.

Angle XZW is ______ degrees
Answer:
x = 43°
VZW = 146°
XZW = 34°
Step-by-step explanation:
3x + 17 + x - 9 = 180°
4x + 8 = 180°
4x = 172°
x = 43°
VZW =
3(43) + 17 = 129 + 17 = 146°

A plane is flying at 31,348 feet. It needs to rise to 36,000 feet in two stages. In stage 1, it rises 5% of its initial altitude of 31,348 feet. In stage 2, it rises at a rate of 140.3 feet per minute. How many minutes does it take for the plane to rise during stage 2?
Answer:
well, 5% of 31348 is 1567.4
