You may use the Three Angles applet to test your thinking.
1. A triangle where one angle measures 20° and another angle
measures 45º. 115
2. A triangle where one angle measures 120° and another angle
measures 50°
3. A triangle where one angle measures 90° and another angle
measures 1000

Summary
Answer: Triangle 3
Step-by-step explanation:
The angle measures have to add to 180 degrees, so triangle 3 is impossible as it already exceeds this sum with the 2 given angles.

During a sale, a baseball team allows people to buy either a classic ticket (C), or an autograph event ticket (A). Suppose two customers buy one ticket each. What is the sample space for this action? Drag and drop the choices into the box to correctly complete the table. If an item is not in the sample space, do not drag it to the table.
Sample size is the number of subjects that are included in research or survey. The sample space for this action is CC, CA, AC, and AA.
What is a sample size?Sample size can be defined as the number of subjects that are included in research or survey.
As it is given that there are two customers, and each of the customers buys any one of the two tickets, a classic ticket (C), or an autograph event ticket (A).
Now, as each of the customers has two choices, therefore, the sample space for this action can be written as,
CC - When both of the customers buy a classic ticket.
CA - When the first customer buys a classic ticket(C) while the other buys an autograph event ticket (A).
AC - When the first customer buys an autograph event ticket (A) while the other buys a classic ticket(C).
AA - When both of the customers buy an autograph event ticket (A).
Hence, the sample space for this action is CC, CA, AC, and AA.

Evaluate the following expressions if a = 2, b = 3, x = 4, and y = 5.
y+ab/6b+x
Answer:
0.5
Step-by-step explanation:
5+a•b, 2•3 is 6, +5 is 11.
4+6•b, 6•3 is 18, +4 is 22.
I'm using PEMDAS/GEMDAS, which means I did multiplication first.
I'm assuming the / means to divide, so 11/22 is 0.5

Perimeter of a rectangle is 30m. Its length is 10. Find its breadth
2. Find the number of sides of the polygon given the measure of an interior angle of said polygon.
166. 15°
Answer:
Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15. Divide 360 by the difference of the angle and 180 degrees. For example, 360 divided by 15 equals 24, which is the number of sides of the polygon.

Leon has a bag of 4 red balls, 3 green balls and 6 yellow balls. He takes a ball out and replaces it 50 times. Out of those 50 trials he pulls out a green ball 12 times. What is the experimental probability of getting a green ball on his next trial?.
The experimental probability of getting a green ball on the next trial of the Leon is 6/25.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
Experimental probability of an event is the ratio of number of time a particular event occur to the total number of trials.
Leon has a bag of 4 red balls, 3 green balls and 6 yellow balls. He takes a ball out and replaces it 50 times. Out of those 50 trials he pulls out a green ball 12 times.
Here, the number of green ball pulls out is 12 times and the total number of times trials is 50. Thus the experimental probability of getting a green ball is,
[tex]P=\dfrac{12}{50}\\P=\dfrac{6}{25}[/tex]
Thus, the experimental probability of getting a green ball on the next trial of the Leon is 6/25.

The tallest tree in the world is 379 feet tall. How tall will each of the trees be in the year 2030 if their models continue? Is this reasonable for each tree?.
Models are patterns that are used to predict measurements and populations
How to model the treeThe question is incomplete, as the model and the dataset to model that growth of the tree are not given.
So, I will give a general explanation
If the model of the tree follows a linear model (e.g y = 2x + 3), then the model is not reasonable.
This is so because, population and growth cannot be measured by a linear model
However, if the growth of the trees follow an exponential model (e.g y = 2(3)^x), then the model is reasonable

find the surface area
Answer:
70 inches²
Step-by-step explanation:
We can break this shape up into 5 different shapes.
Two triangles, and three rectangles.
The three rectangles will be A = L * W and are all the same size,
A = L * W
A = 3(L * W)
A = 3(10 * 2)
A = 3(20)
A = 30 inches²
Now, we need to find the area for the two triangles. Usually, you would take the base times the height and divide by two, but since we have two triangles of the same size we do not need to divide by two,
A = B * H
A = 10 * 4
A = 40 inches²
Last, we will add the two areas for the triangles and rectangles together,
40 inches² + 30 inches² = 70 inches²
Fernando had to pay $1.40 in sales tax when he purchased a shirt. If the sales tax rate is 7%, how much did his shirt cost? please give explanation thank you
Answer:
it's answer is 1.34 but it can be wrong also
Answer:
$20
Step-by-step explanation:
Fernando paid $1.40 as sales tax and the sales tax rate is 7%.
We can write,
Total cost * 7% = 1.4
Total cost = 1.4/0.07 SInce 7% = 0.07
So, total cost = $20

What is the length of line HI and IJ
Answer:
HI = [tex]4\sqrt{41}[/tex] , IJ = [tex]4\sqrt{41}[/tex]
Step-by-step explanation:
The number of AB spaces is 15, the BC is 20, and the CD is 15. Looking at the given length, you can see that it is twice the number of cells.
If you draw a line perpendicular to the line HG in I, it becomes a right triangle. The lengths of HI and IJ can be calculated using Pythagoras on a right triangle.
Suppose that the vertical line is L.
HL = 10
IL = 8
(HI)² = (HL)²+ (IL)² = 10²+8²=164
HI = [tex]2\sqrt{41\\[/tex] -> (It's twice the number of spaces.) -> HI = [tex]4\sqrt{41}[/tex]
IJ can be obtained in the same way.
IJ = [tex]2\sqrt{41\\[/tex] -> (It's twice the number of spaces.) -> IJ = [tex]4\sqrt{41}[/tex]

Collin is playing a video game. He wins 25 points for each gold coin he finds. His goal is to win more than 200 points. He wants to know how many gold coins he needs to find.
Let b be the number of boxes of crayons Ms. Cohen buys. Write an inequality that represents the situation
what is the expression for this problem??
Answer:
8.
Step-by-step explanation:
The ratio or fraction for this problem would be 1 (gold coin) : 25 (points)
If we want to find out how many gold coins he needs to get 200 points we need to divide 200 by 25.
200/25 : 8
if we want to check our answer do this
1:25
1 x 8 is 8
25 x 8 is 200
Soo... Collin needs to find 8 coins to win 200 points.
