Answer:
The set (39, 80, 89) can be used to make a right triangle. Thus, option D is correct.
Explanation:
We know that right-angle triangles obey the Pythagoras theorem, i.e.,
a² + b² = c²
Let's check for each set:
(39, 41, 45): 39² + 41² ≠ 45²
(39, 49, 59): 39² + 49² ≠ 59²
(39, 69, 99): 39² + 69² ≠ 99²
(39, 80, 89): 39² + 80² = 89²
AB=(8/-4). BC=(6/4)

You spin the spinner, flip, a coin, then spin the spinner again. Find the probability of the compound event. The probability of spinning an odd number, not flipping heads, then not spinning six is?
Answer:
20/81.
Step-by-step explanation:
There are 5 odd numbers in 1 to 9 and 4 even ones.
Prob(Odd number on first spin) = 5/9
Prob(Not flipping heads on second) = 1/2
Prob(Not spinning a 6 on third ) = 8/9
The compound probability is found by multiplying the above ( because each trial is independent of the others):
Answer = 5/9 * 1/2 * 8/9
= 40/162
= 20/81.

Kylie went on a road trip with her family. They traveled at an average speed of 50 miles per hour for 2.5 hours and then traveled at an average speed of 65 miles per hour for 3 hours. What was the total distance in miles that Kylie’s family traveled during this time?
Answer: 320 miles
Step-by-step explanation:
First, we need to make an equation. However, we can’t fight to label the variables:
t = total number of miles
h = number of hours
Now let’s set up our equation:
t = 50h + 65h
The good thing is that we know how many hours each speed was held for, so we can substitute it in the equation.
t = 50(2.5) + 65(3)
t = 125 + 195
t = 320
Therefore, the total number of miles traveled is 320.
The total distance in miles that Kylie’s family traveled during this time is 320 miles.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that Kylie traveled at an average speed of 50 miles per hour for 2.5 hours and then traveled at an average speed of 65 miles per hour for 3 hours.
First, we need to make an equation thus we have;
t = total number of miles
h = number of hours
Now let’s set up our equation as;
t = 50h + 65h
Now we can substitute it in the equation.
t = 50(2.5) + 65(3)
t = 125 + 195
t = 320
Therefore, the total number of miles traveled is; 320 miles.

Luis drank 12 gallons of juice from the carton how many quarts of juice did Luis drink
Luis drank 48 quarts of juice. This is calculated by multiplying the known quantity of 12 gallons by the conversion factor of 4 quarts per gallon.
Explanation:This question involves a unit conversion from gallons to quarts. In the US customary measurement system, we know that 1 gallon is equal to 4 quarts. Since Luis drank 12 gallons of juice, to find out how many quarts Luis drank we would perform the following multiplication:
12 gallons x 4 quarts/gallon = 48 quarts
Therefore, Luis drank 48 quarts of juice.

Can you subtract closed polynomials
Answer:
Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. This guarantees that the difference has variables and exponents which are already classified as belonging to polynomials.

A motorboat travels 9 miles downstream (with the current) in 30 minutes. The return trip upstream (against the current) takes 90 minutesWhich system of equations can be used to find x, the speed of the boat in miles per hour, and y, the speed of the current in miles per hour? Recall the formula d = rt..
Answer:
Option B
Step-by-step explanation:
When moving with the current, the speeds of the boat and current will add up. The first situation can then be represented by:
9 = 0.5(x + y)
While opposing the current, the speeds will be subtracted. Forming:
9 = 1.5(x - y)
The second option contains this equation system, so it is correct.
Answer:
it is B

Quincy folds a piece of cardboard to make the three sides of a triangular prism open at top
and bottom. The triangular prism and the piece of cardboard that he used are shown below.
What is the area of the piece of cardboard?
Answer:
500 cm2
Step-by-step explanation:
The dimensions of the prism are 7 cm, 9 cm and 20 cm.
So the three areas we want to find are three rectangles, with the sides:
7 cm and 20 cm, 9 cm and 20 cm, 9 cm and 20 cm
The area of each rectangle is:
rectangle_1 = 7 * 20 = 140 cm2
rectangle_2 = 9 * 20 = 180 cm2
rectangle_3 = 9 * 20 = 180 cm2
Summing all these three areas, we have:
Total area = 140 + 180 + 180 = 500 cm2
Answer:
500 Square Centimeters

The area of Australia/Oceania is approximately 7.69 × 106 square kilometers. Its population is approximately 3.11 × 107 people. What is the approximate population density (people per square kilometer) of Australia/Oceania? Write your answer in standard form. If necessary, round your answer to the nearest hundredth.
Answer: 3.11*10^7/7.69*10^63110/769 Answer:4.04
will I still get brainliest?
The population density of Australia/Oceania is calculated by dividing the total population (3.11 × 107 people) by the total area (7.69 × 106 square kilometers), which results in a density of approximately 4.04 people per square kilometer.
Explanation:To calculate the population density of Australia/Oceania, we need to divide the total population by the total area. The area of Australia/Oceania is approximately 7.69 × 106 square kilometers, and the population is approximately 3.11 × 107 people.
The calculation for population density is:
Population Density = Total Population / Total Area
So:
Population Density = 3.11 × 107 people / 7.69 × 106 square kilometers
This results in a population density of
Population Density = 4.04363 people per square kilometer (unrounded)
Rounded to the nearest hundredth, the population density is approximately 4.04 people per square kilometer.
