Marcus tosses a coin and spins a spinner numbered from 1 to 3. What is the probability the coin lands heads up and the spinner lands on 1?
Answer:
1/6
Step-by-step explanation:
Answer: [tex]\dfrac{1}{6}[/tex]
Step-by-step explanation:
Given statement : Marcus tosses a coin and spins a spinner numbered from 1 to 3.
Let A be the event of getting a head while tossing a coin.
Total faces on coin=2
Then [tex]P(A)=\dfrac{1}{2}[/tex]
Let B be the event of spinner lands on 1.
Total sections on spinner = 3
Then [tex]P(B)=\dfrac{1}{3}[/tex]
Since both events are independent of each other.
Therefore, the probability the coin lands heads up and the spinner lands on 1 = [tex]P(A)\timesP(B)=\dfrac{1}{2}\times\dfrac{1}{3}=\dfrac{1}{6}[/tex]
Hence, the probability the coin lands heads up and the spinner lands on 1 = [tex]\dfrac{1}{6}[/tex]

Find two equivalent fractions for 2/12
You can find two equivalent fractions by multiplying or dividing the numerator and denominator by the same number.
For example, if you had 2/3 and you wanted to find an equivalent fraction, you could multiply both the numerator (top number) and denominator (bottom number) by 2.
2/3 * 2/2 = 4/6, so an equivalent fraction of 2/3 is 4/6.
Now to find two equivalent fractions for 2/12: since both the numerator and denominator can be divided evenly by 2, you can divide 2/12 by 2/2.
2/12 / 2/2 = 1/6
1/6 is an equivalent fraction to 2/12.
You can also multiply 2/12 by 2/2 for another equivalent fraction.
2/12 * 2/2 = 4/24, so two equivalent fractions for 2/12 are 1/6 and 4/24.
Two equivalent fractions for 2/12 are 4/24 and 6/36.
To find equivalent fractions for 2/12, we need to multiply both the numerator and denominator by the same non-zero number. This will give us fractions that have different numerators and denominators but represent the same value.
Let's start by finding an equivalent fraction by multiplying both the numerator and denominator by 2:
2/12 x 2/2 = 4/24
The fraction 4/24 is equivalent to 2/12 because both fractions simplify to 1/6 when reduced to their simplest form.
Next, let's find another equivalent fraction by multiplying both the numerator and denominator by 3:
2/12 x 3/3 = 6/36
The fraction 6/36 is also equivalent to 2/12 because both fractions simplify to 1/6 when reduced.
Therefore, two equivalent fractions for 2/12 are 4/24 and 6/36, both of which represent the same value as 2/12, which is 1/6 when simplified.

four students estimated the width of the door to their classroom .who made the best estimate?a,ted:1foot,b,hank,3 feet,c,ann,10feet,d,maria,15feet
Ann's and Maria's estimations of 10 feet and 15 feet are much wider and there would be no door with these widths.
Ted's estimation of 1 foot is also not possible as some stout students can't enter into the class. :D
Hence, Hank's estimation of 3 feet is the best estimate.
Hank made the best estimate of the width of the door at 3 feet, as standard interior doors are usually close to this width.
The question is about estimating the width of a door. Students provided different estimates for the door's width: Ted estimated it to be 1 foot, Hank estimated 3 feet, Ann estimated 10 feet, and Maria estimated 15 feet. To determine who made the best estimate, we can use the contextual knowledge of standard door sizes. Typically, the width of an interior classroom door is closer to 3 feet, which makes Hank's estimate the most reasonable. The estimates provided by Ann and Maria are excessively large for typical doors, and Ted's estimate of 1 foot is too small.
(02.06)How many pounds are there in 2 and 3 over 4 tons? (1 ton = 2000 pounds)
So we have 2 3/4 tons.
2 tons = 4000 pounds.
3/4 = 75%
We know that 50% (or half) of 2000 is 1000.
Since we have 75%, we can take another half of 1000 and add that to our 1000.
1000/2 = 500
1000 + 500 = 1500
2 and 3/4 tons is equal to 5500 tons.

40 = 8y
Answer: 5
Step-by-step explanation:
To solve this equation, you would divide 8 by both sides of the equation to isolate the y variable. this would leave you with the the answer y = 5. To check this solution, you would simply do the reverse operation (multiply 5 by 8). Since multiplying 8×5 = 40, the answer is correct :)
Solving the equation, 40 = 8y, the solution is 5. Substituting y = 5 into the equation to check the solution will give us 40 = 40, which means the solution is correct.
How to Check the Solution to an EquationAfter solving an equation to determine the value of a variable, plug in the value of the variable into the equation. If the solution is correct, the right side will be equal to the left side of the equation.Given:
40 = 8y
Divide both sides by 8
5 = y
y = 5
Check the Solution: Plug in the value of y into 40 = 8y
40 = 8(5)
40 = 40 (True).
Thus, solving the equation, 40 = 8y, the solution is 5. Substituting y = 5 into the equation to check the solution will give us 40 = 40, which means the solution is correct.

Harold stores 10656 pounds of grain for his 24 cattle.Each cow eats about 12 pounds of grain each day.how many days would the food supply last?
Hey there!
If he has 24 cattle that eat 12 pounds of grain every day, then the amount of grain that they eat every day can be represented by the following equation:
p = 24 x 12 Multiply the two together, and the amount eaten each day is 288 pounds.
We can divide 10656 by 288 to figure out how many times 288 will go into 10656, which tells us how many days the supply will last.
10656 ÷ 288 = 37
So this means the food supply will last 37 days.

The temperature dropped 30°F in a 6 hour period. What was the mean hourly temperature drop?
The mean hourly temperature drop is 5°F per hour, calculated by dividing the total temperature drop of 30°F by the total time of 6 hours.
Explanation:If the temperature dropped 30°F over a period of 6 hours, the mean hourly temperature drop is calculated by dividing the total temperature drop by the total time.
This calculation provides the average rate of temperature change per hour.
To find the mean hourly temperature drop, you use the following steps:
Determine the total temperature change: 30°F.Determine the total time of the change: 6 hours.Divide the total temperature drop by the total time to find the mean hourly drop: Mean Hourly Drop = Total Temperature Drop ÷ Total Time.Perform the calculation: Mean Hourly Drop = 30°F ÷ 6 hours = 5°F per hour.Therefore, the mean hourly temperature drop is 5°F per hour.
Final answer:
The mean hourly temperature drop when the temperature decreased by 30°F over a 6-hour period is 5°F per hour.
Explanation:
The question asks to determine the mean hourly temperature drop when the temperature decreased by 30°F over a 6-hour period. To find the mean hourly drop, you simply divide the total temperature drop by the total number of hours.
To calculate: Mean hourly drop = Total temperature drop ÷ Number of hours
So in this case, it would be: Mean hourly drop = 30°F ÷ 6 hours = 5°F per hour
Therefore, the mean hourly temperature drop was 5°F.
