If a quadrilateral has these known angle degrees: 35, 35 and 145, what are the degrees of the fourth angle?
Answers
Answer:
145
Step-by-step explanation:
The total sum of all the angles is 360 degrees. If we add up 35, 35, and 145 we get 215. 360-215=145.
i only need the awnser for questions 4 and 2 because i dont get them
Answers
Answer:
2) 20 students
4) 28 students
Question 2 is 25% - but it's asking how many. If you know the total number of students multiply that times .25 and that number is your answer. So .25 x 80 = 20
Question 4 is 35% also multiplied times the total number of students. So it would be the total number of students multiplied times .35.
So .35 x 80 = 28
Both of these questions want the number of students, not the percent.

Take 75 / 15. Then in that many times, they will meet again. The answer is 75/15 = 5, so at 7:15 AM , they will meet again. Think of this like Chemistry. There is a restricting reactant and a non restrictive reactant. If you have 200 slices of bread, and 150 slices of cheese, the bread could only support 100 sandwiches. You'd have 50 slices of cheese left over. So the bread is the restrictive, or, in this case, 75, and the cheese is the non-restrictive number, or, 15. Hope this helps :)

Answer:
16.36 ft3
Step-by-step explanation:
Volume of a Cylinder
V= π r2 h
π • 1.253 • 2.5 = 12.27ft3
Volume of a Hemisphere
2 • π • 1.253
2 • π • 1.95
12.26 /3 = 4.09 ft3
Both
4.09 ft3 + 12.27 ft3 = 16.36 ft3

a. 15
b. 17
c. 11
d. 21
Answers
Answer:
c. 11
Step-by-step explanation:
3p + 10 = 2p + 21
Subtract 2p from both sides.
3p - 2p + 10 = 2p - 2p + 21
Simplify.
p + 10 = 21
Subtract 10 from both sides.
p + 10 - 10 = 21 - 10
Simplify.
p = 11
Answer: c. 11
Answer:
c.11
Step-by-step explanation:
3+10=2+21
3+10−10=2+21−10
3=2+11
3−2=2+11−2p
=11

Suppose you roll a special 34-sided die. What is the probability that the number rolled is a "1" OR a "2"?
Answers
P(1 or 2) = P(1) + P(2) = 1/34 + 1/34 = 2/34 = 1/17.
So the probability of rolling a 1 or a 2 is 1/17.

If you were flipping a coin, and needed to get 2 heads in a row, what is the probability of getting two heads in a row. Use your probability tree to help. /
Answers
Answer:
1/4
Step-by-step explanation:
If you flip it twice the possible outcomes are
H H
H T
T H
T T
The chances of you getting H H is 1 / 4. If you flip it more than twice, the probability changes. Let's try three times. That gives you 8 different choices.
H H H *
H H T *
H T H
H T T
T H H *
T H T
T T H
T T T
What this gives is 3 chances out of 8 which is 0.375 and that's better than 0.25
Four would give you an even better result, There are 16 ways of flipping a coin 4 times. The successful results are
H H H H
H H H T
H H T T
H H T H
T H H T
T T H H
H T H H
I'm sure there might be a couple of more, but already you have done better than 3/8

Answers
Answer:
1) x = 5√3, y = 5
2) x = 16, y = 8
3) x = 10, y = 5
4) m = 9√15/10, n = 9√5/10
5) x = 3√3/2, y = 3/2
6) x = 6√5, y = 3√5
7) x = 5, y = 5
8) x = 5√2, y = 5
9) a = 2, b = √2
10) m = 10√6/3, n = 5√6/3
Explanation:
For special right triangles, there is a certain side ratio that applies due to the angle measurements which are opposite of the corresponding angles.
For 30° - 60° - 90° triangles (Scalene Right), we can use x as a marker for the side opposite of 30°, the side opposite of the 60° angle will be x√3, and the side opposite of the 90° angle will be 2x.
For 45° - 45° - 90° triangles (Isosceles Right),
Both 45° angles can be thought of as x, and the 90° angle can be thought of as x√2.
This is all computed as a result of the trigonometric functions:
SOH CAH TOA.
This is a shortcut for these specific triangles.
If you do not have the side marked as x, just do the inverse operation to get it.
90° is always opposite of the hypotenuse (longest side of a triangle; looks like a slant)
