What is the value of x?
Answer:
28!
Step-by-step explanation:
soooooo its a 90 degree angle
2x+1+33=90
2x+34=90
-34
2x=56
x=28
Answer:
x = 28°
Step-by-step explanation:
As you see that the angle is an right angle where right angles = 90°
So,
(2x + 1) + 33 = 90°
Subtract 33 on both sides:
2x + 1 = 57
Subtract 1 on both sides:
2x = 56
Divide 2 on both sides:
x = 28°
Rebecca is playing a video game that involves planting and cutting down trees. She moves up an energy level for each tree she plants, and she moves down a level for each tree she cuts. If Rebecca reaches energy level 10, she will earn bonus points.
Rebecca is currently at energy level 4. The results of her next 3 turns are:
Turn 1: 6 trees cut
Turn 2: 8 trees planted
Turn 3: 1 tree cut
3. What is Rebecca's energy level after Turn 2?
4. What is Rebecca's energy level after Turn 3? Will she earn bonus points after Turn 3? Explain why or why not.
Answer:
3. 6 energy points after turn 2
4. 5 energy points after turn 4
no bonus points cause she never reached 10 points
Help me guys it is homework pleased ⇄ ∛
Answer:
I haven't done these in 2 years and I'm not sure if I remember things correctly but here's what I would put down.
5) No, it is not because the sizes of each section are not even.
6) Yes, this is fair since there are a even chance of getting each number.
7) 3 out of 25 or 3/25
8) The bag with 250 colored tiles would give him a less chance of picking a blue tile. In the first bag, there is a 40% chance that Greg would pick a blue tile while the second bag, he would have a 30% chance of picking a blue tile. To get these percentages, I divided the the amount of blue tiles in the bag by the total amount of tiles.
Explantion for question 8: 10 blue tiles in a bag of 25 so you would do 10/25 which is .4 and as a percentage it would be 40%. For the second question, 75 blue tiles out of 250 total so 75/250 and that would be .3 and as a percentage, it would be 30%. The "/" is a fraction bar and is sometimes used as a division symbol as well, just in case you don't know:)

Using what you know about fair and unfair games, as well as expected value, design a game that will be fair to both you and the player. Be creative in your design, trying not to mimic anything that you have already seen in this course or in searching the internet. Include a thorough description as well as a visual representation of the game that includes evidence of fairness.

KING OF QUESTIONS!!!
Step-by-step explanation:
Each player starts out with 10 tokens ( tokens can be anything I recommend spare change or coins. ) the tokens will be used as point tallies at the end of the game. But to determine who goes first the question master asks a question from the starting deck( The easiest questions) and starting with player one the players answer and whoever answers with the correct answer will go first, the other players will form an orderly line from closest to the correct answer to farthest. ( If there are more than 1 successful answers you pull another card from the next deck. This is an increase in difficulty. And it will keep increasing until there is one person with the correct or closest answer or until they reach the end of the final deck. Remember that this event is highly unlikely) After this is done the game begins. The question master asks a question the players will answer. The players that get it correct will receive 2 token. The players that do not but are close get 1 and the player to get the farthest from the correct answer loses 1 token. ( Tokens are worth 1 point.)
Roles:
Player 1 ( Answers the questions.)
Player 2 ( Answers the questions.)
Player 3 ( Answers the questions.)
Player 4 ( Answers the questions.)
Question Master & Token Master ( Asks the questions and gives the token to the correct answer. )
How to Win:
Quick Match- Play until a player reaches 30 tokens.
Long Match- Play until all but one player is eliminated.
Ways to Lose- If a player loses all of there tokens or is cheating they are eliminated, this happens only when the player is caught cheating or stealing tokens from other players or when the player loses all of these tokens due to incorrect answers.

Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
Hi!
Here is the definition of a net from www.icoachmath.com:
“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”
In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.
Hope this helped,
Caroline
The figure shows a trapezium PQRS where RS = 17m and PS = 15m. If PT = 14m, and the area of trapezium is 196m2, Find the length PQ.
Answer:
PQ = 11 m
Step-by-step explanation:
In trapezium PQRS,
PQ and RS are parallel lines and PT is the perpendicular distance between the parallel lines
a = PQ
b =RS = 17 m
d = PT = 14 m
[tex]\frac{(a+b)*d}{2}= 196\\\\\frac{(PQ + 17)*14}{2}=196\\\\(PQ + 17) * 7 = 196\\\\PQ + 17 = \frac{196}{7}\\\\PQ + 17 = 28\\\\PQ = 28 - 17\\\\PQ = 11[/tex]

A state representative took several random surveys of adults to find which place they visited most frequently.
The average of all of the surveys is shown in this table.
Places & Average of Surveys
ZOO 31
Museum 14
Park 17
Aquarium 8
Based on the table, which conclusion can be made?
А. On average, 50% of the adults visited the zoo most frequently.
B. On average, 17% of the adults visited the park most frequently.
C. On average, 2 out of 25 adults visited the aquarium most frequently.
D.On average, 2 out of 10 adults visited the museum most frequently.
Answer:
D.
Step-by-step explanation:
In total, there are 70 people.
31/70= around 44.2%
14/70= 20%=2/10
17/70= around 24.2%
8/70= around 11.4%
Using proportions, it is found that the correct statement is given by:
D. On average, 2 out of 10 adults visited the museum most frequently.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there is a total of 31 + 14 + 17 + 8 = 70 adults.
Applying the rule of three, 2 out of 10 considering 70 adults is equivalent to 14 adults, hence option D is correct.

Answer:
F
Step-by-step explanation:
This is F. This is because, when both sides of the triangle is 42, and when you add it up it is 84. Now 84 + x will be the answer. The total sum of all of the measurements of a triangle is ALWAYS 180! So, the answer is the first option F.

The pacific ocean covers 1/3 of Earth surface the Atlantic Ocean cover 1/5 of Earth surface, what fraction of Earth surface is covered by both oceans?
Answer:
Here I answered it
Step-by-step explanation:
1/3 + 1/5
1 x 5/3 x 5 + 1 x 3/5 x 3
5/15 + 3/15 = 8/15
The part of earth covered by both of the oceans is 8/15
What is a fraction?A fraction represents part of a whole. When something is broken up into a number of parts, the fraction shows how many of those parts you have.
Given that, The Pacific Ocean covers 1/3 of the Earth surface the Atlantic Ocean covers 1/5 of the Earth surface,
To find the total area covered we will add both the area,
1/5+1/3
= 8/15
Hence, The part of earth covered by both of the oceans is 8/15

What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
Answers:
Scale Factor = 3/4
This is a reduction
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image
