Answer:
Step-by-step explanation:
Short answer No They are not congruent. The scale factor would be 1 if they were. JL and RT should both be the same length (they are opposite angles marked with 2 quarter circles). They are not equal. So the scale factor is not 1.
To get from JKL to RST you must multiply every length of JKL by = 20 / 25 or 4/5. So 15 * 4/5 = 12 which works. 4/5 * 20 = 16 which also works.
The two triangles are similar.

1. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
What is the sample space for Janessa’s calculation?
A. [3, 4]
B. [1, 2, 5, 6]
C. [1, 2, 3, 4, 5, 6]
D. [5, 6]
2. Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
A. Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.

Step-by-step explanation:
ill edit to find the rest of the answers
a) The sample space for Janessa's calculation is [ 5 , 6 ]
b) Her probability of winning is a dependent event because it depends on the results of her friends' rolls.
c) The number of desired outcomes for Janessa's probability is 2.
d) There are 29 possible outcomes
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
a)
Since Janessa needs to roll a number higher than both her friends to win the game, the possible outcomes for her roll are limited to 5 and 6, since these are the only numbers that are higher than 4 and 3. Therefore, the sample space for Janessa's calculation consists of the numbers 5 and 6, which can be written as [5, 6]
b)
The probability of Janessa winning is a dependent event because it depends on the results of her friends' rolls. If one of her friends had rolled a higher number, then the probability of Janessa winning would be 0. Therefore, the outcome of Janessa winning is dependent on the outcomes of her friends' rolls.
Hence , her probability of winning is a dependent event because it depends on the results of her friends' rolls.
c)
Janessa needs to roll a number higher than both friends, and the only numbers that meet this criteria are 5 and 6. Therefore, the number of desired outcomes for Janessa's probability calculation is 2.
d)
There are a total of 8 + 7 + 14 = 29 pens in the bag. When Denato pulls a pen from the bag, there are 29 possible outcomes since he can choose any of the 29 pens in the bag.
Hence , the probabilities are solved

Why do you think that becoming an astronaut is difficult?
Answer:
A) Because of all the specific requirements there are for astronauts
Step-by-step explanation:
B doesn't make sense, because there are many people who aren't afraid of going into space
C is true, but there are multiple places where you could become an astronaut. NASA isn't the only place!
D is (really just absurd!) incorrect because, in fact, space research is important! Humans need to know what's in space to protect humanity and to possibly uncover more secrets
A is the answer because you need to meet all the requirements and pass many tests

Here are two patterns made using identical rhombuses. Without using a protractor, determine the value of a and b.
Answer:
a = 60°
b = 120°
Step-by-step explanation:
First, you can find measure a by using the first shape. There are six rhombuses, and you can use the innermost a of each one to form a circle. A full circle is 360°, so divide 360 by six. The answer is sixty. So on the next shape, the a measurements add up to 120°. Subtract that from the circle: 360 - 120 = 240. And since there are two measurements for b, you would divide 240 by two. The answer is 120.
To check your work, use the knowledge that circles are 360° (the four interior corners of a rhombus will also add up to 360°. 2(120) + 2(60) = 360. Hope this helps! Feel free to ask any questions!

Find the value of x.
Answer:
x=25
Step-by-step explanation:
In the △,
all the 3 angles add up to 180°
So,
(2x+15)°+x°+90°=180°
3x°+105°=180°
3x°=180°-105°
3x°=75°
x=75°÷3°

The probability model based on experimental probability for randomly selecting a marble from a bag is P(green) = 18/40, P(blue) = 14/40, and P(white) = 8/40. About how many marbles of each color are in the bag if there are 60 total marbles?
Answer:
P(green) = 27
P(blue) = 21
P(white) = 12
Step-by-step explanation:
multiply the numbers so that the denominator is 60, multiply by 1.5/1.5:
18/40 * 1.5/1.5 = 27
14/40 * 1.5/1.5 = 21
8/40 * 1.5/1.5 = 12

Answer:
y = -4x + 60
Step-by-step explanation:
(0, 60) and (4,44)
Slope:
m=(y2-y1)/(x2-x1)
m=(44 - 60)/(4-0)
m= (-16)/4
m= -4
Slope-intercept:
y - y1 = m(x - x1)
y - 60 = -4(x - 0)
y - 60 = -4x
y = -4x + 60

SOLVE FOR ANGLE P PLEASE FOR BRAINLIEST :) NO EXPLANATION NO BRAINLIEST
Answer:
50 degrees
Step-by-step explanation:
In triangles, the sum of all angles = 180 degrees. So, we can create an equation to solve for x:
Angle 1 + Angle 2 + Angle 3 = 180 degrees(x+15) + (x+28) + 67 = 180 2x + 110 = 1802x = 70x = 35We found x, but we're not done. Now, we substitute to find each missing angle:
Q = x + 28 = (35) + 28 = 63 degreesP = x + 15 = (35) + 15 = 50 degreesThus, our final answer is: Angle P = 50 degrees.
Answer:
50
Step-by-step explanation:
The sum of all the angles of a triangle equals 180 no matter what so to do this you will have to make an equation:
x + 15 + x + 28 + 67 = 180
Everything on the left side of the equation is the angles.
When you solve this equation you should eventually get
x = 35
Now that you have x you can find angle P. Angle P is x + 15 so when you substitute x, you get 35 + 15.
So the answer is 50°
