Answer:
PR = 25 cm
SR = 27.73 cm
Step-by-step explanation:
PSR and PQR are right triangles.
First, you can find PR using the Pythagorean theorem.
[tex]PR = \sqrt{24^2+7^2} =\sqrt{625} = 25 cm[/tex]
Now let's do the same thing for the other triangle:
[tex]SR=\sqrt{25^2+12^2} =\sqrt{769} = 27,73 cm[/tex]

Answer:
For question 2, it is C) 3a.
For question 3, it is B) 3.
Step-by-step explanation:
For question 2, we are given that Mary's age is a and her mother's age is 3 times as old as Mary. The key word is "times" so this means that the expression can be written as 3a or 3 * a.
For question 3, the question asks for the greatest number that divides evenly into both 42 and 81. Using simple math, C and D automatically elliminates itself because one of the numbers divided gives a whole and the other gives a decimal. All is left is A and B. Obviously, a number divided by one will by itself so it stays even either way and the two numbers divided by 3 will give us two whole numbers and 3 is the greatest possible number so that concludes that it is B.
Pablo makes a spinner to model the probability of simultaneously flipping a "heads" on a nickel, a "heads" on a dime, and a "heads" on a quarter. He divides his spinner wheel into sections for each possible combination of coin flips, and he colors green the section representing simultaneously flipping three "heads." If he decides to spin the arrow on the spinner 24 times, how many times can he predict the arrow will land on the green section?

Step-by-step explanation:
Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V?
The probability of picking a tile that is the letter V from the second bag is: As a fraction: 250/500 = 1/2 and As a percent: (1/2) x 100% = 50%.
What is probability?Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that it is certain. The closer the probability is to one, the more likely it is that the event will occur.
Probability can be used to make predictions and decisions in a variety of fields such as finance, statistics, and so on.
It is also an important concept in comprehending probability laws and the behaviour of random events.
The probability of picking a tile that is the letter V from the second bag is:
As a fraction: 250/500 = 1/2
As a percent: (1/2) x 100% = 50%
Thus, comparing the probabilities, the second bag is more likely to contain a tile with the letter V since the probability of picking a V from the second bag is higher (1/2 or 50%) than from the first bag (7/25 or 28%).

"Find the measure of each angle in the following diagram"
Answer:
Each angle is 60°
Step-by-step explanation:
The 2 angles are equal to each other because they're alternate exterior angles:
10x - 20 = 7x + 4
10x - 7x = 4 + 20
3x = 24
x = 8
10x - 20
10(8) - 20
80 - 20
60
Since these angles are exterior angles, their angle measures are equal so they both are 60°

Step-by-step explanation:
While sitting on a park bench, Tanisha counts that 16 out of 20 people who walk by her have a pet with them.
Part A. What is the probability that a person who walks by Tanisha has a pet?
Part B. What is the probability that a person who walks by her does not have a pet?
Answer:
the answer would be-
Step-by-step explanation:
The probability that a person who walks by Tanisha has a pet- 0.8
The probability that a person who walks by Tanisha does not have a pet- 0.2
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
Part A. The probability that a person who walks by Tanisha has a pet can be calculated by dividing the number of people who have a pet by the total number of people who walk by her. In this case, 16 out of 20 people have a pet, so the probability is:
P(having a pet) = 16/20 = 4/5 = 0.8
So, the probability that a person who walks by Tanisha has a pet is 0.8 or 80%.
Part B. The probability that a person who walks by Tanisha does not have a pet can be calculated by subtracting the probability of having a pet from 1. That is:
P(not having a pet) = 1 - P(having a pet)
P(not having a pet) = 1 - 0.8
P(not having a pet) = 0.2
So, the probability that a person who walks by Tanisha does not have a pet is 0.2 or 20%.

Answer:
A = 8, B = 6, C = 4 , D = 7
Top = 29
Side = 20
Step-by-step explanation:
Last row : A + A + A + A = 32 ==> A = 8
First row : D + A + D + D = 3D + 8 = 29
3D = 21 ==> D = 7
Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27
2B = 12 ==> B = 6
Third column : D + A + C + A = 27
7 + 8 + C + 8 = 27 ==> C = 4
