When multiplying decimals, how do you determine where to place the decimal in the answer?

Answers

Answer 1
count the numbers right to the decimal point ,and then count that much of numbers from right to left and apply it.
Example:  2.50
             *  2.50
                _____
               6.2500     There is 4 numbers right to the decimal point totally....and the answer.  
Answer 2
Final answer:

When multiplying decimals, the decimal in the answer is placed based on the total count of digits following decimals in the original numbers. For example, multiplying 0.4 by 0.20 gives 0.08, not just 8.

Explanation:

When you're multiplying decimals, the placement of the decimal in the answer is determined by the total number of digits behind the decimals in the problems you're multiplying. For example, if you're multiplying 0.4 (one digit after the decimal) by 0.20 (two digits after the decimal), your answer should have three digits after it. So, let's multiply: 4 times 2 equals 8, but this should be written as 0.08, not just 8, due to the rule. That's how you manage the decimal placement when multiplying decimals.

The Campers in cabin D walked 1/6 of the way to Mammoth Mountain. how many miles did the walk ?

Answers

what is the question ?
Final Answer:

The campers in cabin D walked approximately [tex]\( \frac{1}{6} \)[/tex] of the total distance to Mammoth Mountain, covering a distance of around [tex]\( \frac{1}{6} \)[/tex] of the total distance.

Explanation:

The problem involves finding the distance walked by the campers in cabin D, who covered [tex]\( \frac{1}{6} \)[/tex] of the way to Mammoth Mountain. To calculate the total distance covered, we need additional information about the overall distance to Mammoth Mountain, denoted as [tex]\( D \)[/tex]. The distance covered by the campers can be represented as[tex]\( \frac{1}{6} \times D \).[/tex]

In the absence of the specific value for [tex]\( D \)[/tex], we cannot provide an exact numerical answer. The fraction [tex]\( \frac{1}{6} \)[/tex] signifies one-sixth of the total distance. For instance, if the total distance is 60 miles, then the campers covered [tex]\( \frac{1}{6} \times 60 = 10 \)[/tex] miles. The actual distance walked depends on the assigned value of D.

In summary, the distance walked by the campers in cabin D is[tex]\( \frac{1}{6} \)[/tex]of the total distance to Mammoth Mountain, represented as [tex]\( \frac{1}{6} \times D \).[/tex]The specific numerical value of this distance is contingent on the total distance [tex]\( D \),[/tex]which is not provided in the given question.

"The Campers in cabin D walked [tex]\( \frac{1}{6} \)[/tex] of the way to Mammoth Mountain. How many miles did they walk?"

what is 1/20 written as a percent?

Answers

You can divide 1 by 20 (1÷20) and get 0.05, then convert that to a percent. A percent means the number divided by 100, so to change a number to a percent, multiply by 100 and add the % sign.
0.05 = 5%

You can also make the fraction have a denominator of 100 since percent means the number over 100.
Multiply 1/20 by 5/5.
[tex] \frac{1}{20}* \frac{5}{5}= \frac{5}{100} [/tex].
5/100 is 5%

5 percent is equivalent to 1/20.

Here we have to write 1/20 as percentage,

Since we know that,

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Now ,

To find the percentage of 1/20 multiply it by 100

⇒(1/20)x10 = 100/20

                  =  5 %

Hence,

1/20 = 5%

if 5.25 MB have been downloaded and 2.25 MB are left. what percent of the application has already been downloaded?

Answers

5.25 + 2.25 = 7.50 MB

x/100 x (7.50) = 5.25
7.50x/100 = 5.25
7.50x = 5.25(100)
7.50x = 525
x = 525/7.50
x = 70
Hence, 70% of the application has already been downloaded. 


The percent of the application has already been downloaded will be [tex]70\%.[/tex]

What is the area of an equilateral triangle that has sides of 2 yards and a height of 4.25 feet?

Answers

The first thing you need to do is convert the yards into feet. In one yard there are three feet. So 2*3=6 now you can do the triangle area equation. 
6*4.25=25.5 then divide by two. 25.5/2=12.75
So the area of the triangle is 12.75 ft^2
Hope this helps

Answer:

12.75 squared

Step-by-step explanation:

Remember convert the yards into feet. 2 yards= 6 feet.

6 feet x 4.25 feet= 25.5 feet

remember a=1/2 b x h

after you get 25.5 divided it by 1/2 or 2

then you get 12.75 squared

REMEMBER TO ALWAYS CONVERT!

Mr. Simpson tutored for students on Monday nine students on Tuesday 16 students on Wednesday and 21 students on Thursday if you continue the pattern how many students will be on friday

Answers

25 pattern is, 7, 5, and then 3. -2 every time
Final answer:

Without a clear, consistent pattern in the number of students tutored from Monday to Thursday, it's challenging to accurately predict the number of students for Friday. The pattern initially provided does not follow a simple arithmetic or geometric sequence.

Explanation:

The question asks for the number of students Mr. Simpson will tutor on Friday, given a pattern of students tutored from Monday to Thursday. The pattern is as follows: 4 students on Monday, 9 on Tuesday, 16 on Wednesday, and 21 on Thursday. Looking at the increase in the number of students each day, we see it goes from 4 to 9 (+5), then 9 to 16 (+7), and 16 to 21 (+5). Noticing a pattern or sequence in these increases can be tricky because it seems to alternate in a way that does not hint at a simple arithmetic or geometric progression.

Given this, the exercise might involve a typo or a misunderstanding. Usually, patterns in mathematics follow a clear rule, whether they are linear (constant increase), geometric (constant multiplication), or another form. If a student or teacher encounters such a problem, it is important to go back and check the original problem for any additional information or to clarify the intended pattern.

Using a different porpotions of: Save Percentage= Saves/shots on goal. Another goalie has a save percentage of 0.907 with 204 saves in his first 6 games. Your friend says that you could find their combined save percentagr by adding 0.914 and 0.907 and then dividing by 2. Explain why this is incorrect. Then show how you would caculate their combined save percentage. Round your answer to the nearest thousandth.


(This goes with another problem: A goalie has a save percentage of 0.907 after playing his first 6 games. He has made 191 saves. How many shots on goal has he faced?


- I got the answer of 174.57.

Would that be correct? ^^^

Answers

yo i am pretty sure that is the correct answer
Final answer:

To find the combined save percentage, you need to calculate the total number of saves and shots on goal for both goalies, and then divide the total saves by the total shots on goal. The combined save percentage is approximately 0.909.

Explanation:

Your friend's approach of adding the two save percentages and dividing by 2 to find the combined save percentage is incorrect. This is because save percentage is not a simple average of multiple percentages. To find the combined save percentage, you need to calculate the total number of saves and shots on goal for both goalies, and then divide the total saves by the total shots on goal.

Goalie 1 has a save percentage of 0.914 with 204 saves. This means that Goalie 1 has faced a certain number of shots on goal which can be calculated by dividing the total saves (204) by the save percentage (0.914). This gives us approximately 223 shots on goal.Goalie 2 has a save percentage of 0.907 with 191 saves. Similarly, we can calculate the approximate number of shots on goal faced by dividing the total saves (191) by the save percentage (0.907). This gives us approximately 211 shots on goal.To find the combined save percentage, you need to add the total number of saves (204 + 191 = 395) and the total number of shots on goal (223 + 211 = 434), and then divide the total saves by the total shots on goal. The combined save percentage is approximately 0.909.
