Explain why 3/4 of 16 is the same as 3 x 16 divided by 4
Please Help
Answers
Answer:
I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.
Step-by-step explanation:
Since 3/4 is a fraction, all fractions can be converted into decimals.
3/4 is also known as 75%, which can be simplified into 0.75 in decimal terms.
Now that you know that 3/4 can be simplified to 0.75, you now need to take that 0.75, and multiply it by 16. You can use a calculator to do this, or you could work it out on a sheet of paper.
An easy way to do this, is to know that 25%, (0.25) of 16 is 4. This is because 4 times 4 is 16. Knowing this, if you are looking for 75% of 16, (0.75) you can multiply 4 by 3, knowing that it is 75% of 16.
The answer to that is 12.
3 x 16 = 48 and if you take 48 and divide it by 4, you will get 12.
You can explain this by writing; I know that 3/4 is 75%, and I also know that 3 times 16 is 48. Since I divide 48 by 4, it is the same as multiplying 4 by 3, knowing that it is 25% of 16.

A card is drawn one at a time from a
well-shuffled deck of 52 cards. In 11
repetitions of this experiment, 2 kings
are drawn. If E is the event in which a
king is drawn in the 11 trials, find the
experimental probability P(E).
P(E) = 11
Enter
Answers
Answer:
\(\dfrac{2}{11}\)
Step-by-step explanation:
It is given that a card is drawn one at a time from a well-shuffled deck of 52 cards.
Total repetitions of this experiment = 11
Number of kings in the experiment = 2
Let E is the event in which a king is drawn in the 11 trials. So
\(P(E)=\dfrac{\text{Number of kings in the experiment}}{\text{Total repetitions of this experiment}}\)
\(P(E)=\dfrac{2}{11}\)
Therefore, the experimental probability P(E) is \(\dfrac{2}{11}\).

Answer:
x = 10
Step-by-step explanation:
x + 10 = 1/3(5x + 10)

After a sequence of transformations involving reflections, rotations, and translations, can someone explain why the final image is congruent?
Answers
Answer: It's congruent because translations, rotations, and reflections only move the shape's location and do not change the shape itself. A rotation changes the shape's position by rotating it around a specific point, but that shape is still the same. Reflections only mirror the shape, so while it will look inverted, it is still the same shape. Translations Only move a shape up or down along the y-axis or laft and right along the x-axis. Congruence essentially means that the shape has the same form and dimensions, not the exact location.

Answer:
B) 60%
Step-by-step explanation:
Percentage formula
\(\sf Percentage=\left(\dfrac{Value}{Total\:value}\right) \times 100\)
To find what percent of 200 is 120, substitute the values into the percentage formula:
\(\begin{aligned}\implies \sf Percentage & = \dfrac{120}{200} \times 100\\\\&=\dfrac{120 \times 100}{200}\\\\&=\dfrac{12000}{200}\\\\&=\dfrac{120}{2}\\\\&=60\%\end{aligned}\)
Therefore, 120 is 60% of 200.

x² = 16² - 11²
x² = 256 - 121 = 135
√x² = x = √135 = 11.6

The length of the third side is 11.6
How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)
