Answer: (5, 12, 13).
Step-by-step explanation:
Pythagorean triples are any three side lengths of a right triangle that are all whole numbers.
The most common triples are (3, 4, 5), (5, 12, 13), and (9, 40, 41).
You can test the options given in the Pythagorean theorem to see if they make the theorem correct.
25 + 64 = 100 is not correct.
9 + 16 = 36 is not correct.
25 + 144 = 169 is correct.
1 + 1 = 4 is not correct.
The correct choice is (5, 12, 13).

Solving systems of equations
Answers
numbers 3x + 2y = 12
y = x + 1
Substitution Method
Since y is already isolated in the second equation we can use that value, to substitute for y in the first equation.
3x + 2 (x + 1) = 12
3x + 2x + 2 = 12
5x = 12 − 2
5x = 10
x = 2
Substitute the computed value of x to the second equation to determine the value of y.
y = 2 + 1
y = 3
Elimination Method
3x + 2y = 12
x − y = −1
Multiply the second equation by 2 to eliminate
x or you can also multiply the second equation by 3 to eliminate y. However since it is easier to multiply by 2, I will follow the first method.
3x + 2y = 12
2x − 2y = −2
Adding the two equations eliminates the y variable.
5x = 10
x = 2
Substitute the computed value of x to the second equation to determine the value of y.
y = 2 + 1
y = 3

First, plug in the radius and height into the equation. V=1/3pi*4^2*9
Next solve. 3.14 x 16 x 9 = 452.16
Then you need to divide 452.16 by 3 to get 150.72
Answer:
150.72
Step-by-step explanation:
v=1/3 * 3.14 *4² * 9
v=1/3 * 3.14 * 16 * 9
v=1/3 * 50.24 * 9
v=1/3 * 452.16
v=150.72
Robert wants to buy lights around the edge of his deck the deck is 49feet and 26feet wide how many yards of lights does he need
Answers
Answer:
150 feet
Step-by-step explanation:
Assuming the deck is a rectangle, you need to multiply each side by 2 and add them together.
Answer:
50 yards
Step-by-step explanation:
Let l = length, w = width, and P = perimeter in feet. Let x equal perimeter in yards.
To solve this problem, we first need to find the perimeter of the deck.
To do so, use the formula 2l + 2w = P.
Since the deck is 49 feet long and 26 feet wide, plug in 49 for l and 26 for w.
2(49) + 2(26) = P
Evaluating 2*49 and 2*26, the equation becomes 98 + 52 = P.
Evaluating 98 + 52, the equation becomes 150 = P.
The next step in this problem is to convert feet to yards. We know that Robert needs 150 feet of lights. Since there are three feet in a yard, we can use the formula P = 3x to find the amount of yards of lights Robert needs.
Plugging in 150 for P, the equation becomes 150 = 3x.
Dividing both sides by 3, the equation becomes 50 = x.
Therefore, the final answer is 50 yards.

Answer:
The answer is 10
Step-by-step explanation: So first we divided 15 by 3 which is 5. Then we times 4 and 5 which is 20. 10+x=20, so x = to 10
Answer:
x = 10
Step-by-step explanation:
4/3 = (x+10)/15
Using cross products
15*4 = 3*(x+10)
60 = 3(x+10)
Divide each side by 3
60/3 = 3/3(x+10)
20 = x+10
Subtract 10 from each side
20-10 = x+10-10
10 = x

A scientist wants to find the average mass of fish living in a large pond. So she will use the masses of a sample of fish from the pond to find the average mass.
Answer the questions below.
(a) Which unit(s) could be used for the unit of measurement? Check all that apply.
1.) minutes
2.) kilograms
3.) grams
4.) milligrams
5.) seconds
(b) Which of the procedures below would be the best way to find the average mass?
1.) Pick 2 fish from a shallow region of the pond and weigh each of them.
2.) Pick 42 fish from a shallow region of the pond and estimate their masses.
3.) Randomly pick 2 fish from the entire pond and estimate their masses.
4.) Randomly pick 42 fish from the entire pond and weigh each of them.
Answers
Answer:
A. 2, 3, and 4
B: 4
Step-by-step explanation:
Average mass is defined as, adding masses of all bodies and then divide by number of bodies.
(a). Kilograms, grams and milligrams
(b) Randomly pick 42 fish from the entire pond and weigh each of them.
(a). Since we are interested in the masses of the fish and not the time
so that, only unit of mass is to be considered.
Therefore, Kilograms, grams and milligrams are used to find the average mass.
(b). Since, Random sampling is a part of the sampling technique in which each sample has an equal probability of being chosen
Therefore, Randomly pick 42 fish from the entire pond and measure their masses. This will provide a representative sample with no bias.

Which equation demonstatres the distributive property?
A. 39 + 9 = 45
B. 39 + 3 = 39(12 + 3)
C. 36 times 9 = 9 times 36
D. (12 + 3)3 = 3(12 + 3)
Answers
Answer:
B
Step-by-step explanation:
The distributive property states that:
a(b + c) = ab + ac
Look at the choices:
A: 39 + 9 = 45
There's nothing of this form; in fact, there aren't even any parentheses, so eliminate A.
C: 36 times 9 = 9 times 36
This is saying 36 * 9 = 9 * 36. Again, there aren't any parentheses. Actually, this demonstrates the commutative property.
D: (12 + 3)3 = 3(12 + 3)
There are parentheses, but they're on both sides, so this can't be right, either. In fact, this is the associative property.
By elimination, the answer is thus B.
The rule of distributive property states that [ a(b + c) = ab + ac ].
So, we need to find an answer choice that contains that specific format.
Option A is incorrect because there is nothing to solve for on the right side.
Option B is correct because it contains the same format as the rule stated above.
Option C is incorrect because its the same as [ 36 * 9 = 9 * 36 ] and it's not in the same format as the rule.
Although Option D has half of the format in the rule, it doesn't have the other half containing what it looks like after the distributive property is appplied. So, this is incorrect as well.
Therefore, the answer is B.

tell whether the events are independent or dependent.Then find P(A and B)...You roll a number cube two times.Event A:You roll an odd number on the first roll.Event B:You roll a 4 on the second roll.
Answers
Answer:
Some probability situations involve more than one event. When the events do not affect one another, they are known as independent events. Independent events can include repeating an action like rolling a die more than once, or using two different random elements, such as flipping a coin and spinning a spinner. Many other situations can involve independent events as well. In order to calculate probabilities accurately, we need to know if one event influences the outcome of other events.
Answer:
The outcome of the first roll does not affect the probabilities of the outcomes for the second roll. Therefore, these events are independent.
Step-by-Step Explanation:
The events are independent since the person rolling had rolled a number cube twice, not switching it for the two events.
