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%

Use place value to find 12x40

Answers

Final answer:

The multiplication of 12 and 40 can be simplified using place value. Breaking down the 40 to 4 and multiplying gives 48, but remember to adjust back for place value, giving the final answer of 480.

Explanation:

To solve the equation 12x40 using place value, you need to understand that '40' is essentially '4' in the tens place which is equivalent to '4x10'. Multiplying 12 by '4' gives us '48'. Now, remembering that 4 was actually in the tens place, we apply the place value and turn it back into '480'.

This method is nothing more than a simplification of the normal multiplication process: you’re just breaking down the 40 into a easier to handle number (4), doing the multiplication, then adjusting for the fact that the 4 was actually in the tens place, not the ones. So, 12x40 equals 480.

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.

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.

A rectangular playground has an area of 3,392 square meters.If the width of the rectangle is 32 meters,find the length.

Answers

The answer is 106 meters. You need to do 3,392 meters divided by 32 meters.

(Length * Width = Area)
(Length = Area / Width)

The length of a playground = 106 meters

Further explanation

The playground is a rectangular shape. There are several properties possessed by rectangular shapes, namely:

1. each angle is equal and is a right angle 2. the diagonals intersect and divide each other equally 3. sides facing the same length

There are two rectangular shapes namely square and rectangle

Square if all sides are the same length

The formula used in rectangular is:

1.Area

Rectangle

[tex]\large{\boxed{\bold{Area=w\:\times\:l}}}[/tex]

w = width

l = length

Square

[tex]\large{\boxed{\bold{area=a^2}}}[/tex]

a = length of side

2. perimeter

Rectangle

[tex]\large{\boxed{\bold{perimeter=2\times(w+l)}}}[/tex]

w = width

l = length

Square

[tex]\large{\boxed{\bold{perimeter=4\times\:a}}}[/tex]

a = length of side

A rectangular playground has an area of 3,392 square meters

[tex]A=3,392\:m^2[/tex]

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.

An insect is 3 inches long what is the length to the nearest hundredth of a centimeter of the insect

Answers

I hope this helps you
Final answer:

To convert the insect's length from 3 inches to centimeters, multiply by the conversion factor of 2.54 to get 7.62 centimeters, which is the length to the nearest hundredth of a centimeter.

Explanation:

The student asked: An insect is 3 inches long what is the length to the nearest hundredth of a centimeter of the insect? To convert the insect's length from inches to centimeters, we need to use the conversion factor where 1 inch equals 2.54 centimeters.

First, we multiply the insect's length in inches by the conversion factor:

3 inches × 2.54 cm/inch = 7.62 centimeters

Therefore, the length of the insect is 7.62 centimeters when converted from inches and rounded to the nearest hundredth of a centimeter.

When measuring the length of small items like insects, it is important to choose an appropriate tool and unit for precision. In this case, a ruler that includes both inches and centimeters would be appropriate for measuring an insect of this size. The centimeter, being smaller than the inch and equivalent to 10 millimeters, offers the precision needed for such measurements.

Juliette and her two brothers spent $45.75 on flowers for their grandmother. Each person will chip in the same amount. How much will each person pay? Juliette's mom decided to chip in $15. Now how much will Juliette and her brothers each pay if they share the amount remaining?

Answers

Final answer:

After dividing the initial total cost of $45.75 by three, each of Juliette and her brothers would pay $15.25. After Juliette's mom contributes $15, the remaining amount of $30.75 is divided by three, resulting in each person paying $10.25.

Explanation:

The question involves dividing a total cost among several people and then re-dividing it after one more person contributes. Initially, Juliette and her two brothers spent $45.75 on flowers. To find out how much each person will initially pay, divide the total cost by the number of people. There are three people, so each person will pay $45.75 ÷ 3 = $15.25.

Next, Juliette's mom decides to chip in $15. After her contribution, the remaining amount to be shared by Juliette and her brothers is $45.75 - $15 = $30.75. Now there are still three people sharing the cost, so each person will pay $30.75 ÷ 3 = $10.25.

Therefore, after Juliette's mom contributes, Juliette and her brothers will each pay $10.25.
