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?

Answers

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.

Polygon LMNOP ~ Polygon QRSTU What is TU?

Answers

Answer:

The answer is B.

Step-by-step explanation:

9 : 12 = 3 : 4

12 : 16 = 3 : 4

Known :

LMNOP ~ QRSTU

OP = 12

LM = 9

QR = 12

Asked :

TU = ...?

Answer :

[tex] \frac{op}{tu} = \frac{lm}{qr} \\ \frac{12}{tu} = \frac{9}{12} \\ tu = \frac{12 \times 12}{9} \\ tu = \frac{12 \times 12}{3 \times 3} \\ tu = 4 \times 4 \\ tu = 16[/tex]

So, the side of TU is 16 (B)

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?

Answers

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

Answers

He drank 48 quarts

the formula to get that answer is multiply the volume value by 4.
Final answer:

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.

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..

Answers

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.

The area of Australia/Oceania is approximately 7.69 × 106 square kilometers. Its population is approximately 3.11 × 107 people.

Answers

Answer: 3.11*10^7/7.69*10^63110/769   Answer:4.04
will I still get brainliest?

Final answer:

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.

Can you subtract closed polynomials

Answers

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.

Step-by-step explanation:

Polynomials are closed under addition. When subtracting polynomials, the variables and their exponents do not change. Only their coefficients will possibly change. ... Remember that the exponents in polynomials are whole numbers. When adding, distribute the positive (or addition) sign, which does not change any of the signs

What is the area of the piece of cardboard?

Answers

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
