convert 1/15 into a decimal correct to 2 decimal places ​

Answers

Answer:

[tex]\frac{1}{15} = 0.\overline{66}[/tex]

Step-by-step explanation:

We proceed to show the procedure to calculate the given fraction into a decimal form:

1) Since numerator is less than denominator, the integer component of the decimal number is zero:

[tex]\frac{1}{15} = 0.xx[/tex]

2) We multiply the numerator by 10 and find the tenth digit:

[tex]\frac{10}{15} = 0[/tex]

Then,

[tex]\frac{1}{15} = 0.0xx[/tex]

3) We multiply the fraction in 2) by 10 and find the hundredth digit:

[tex]\frac{100}{15} = 6[/tex]

Then,

[tex]\frac{1}{15} = 0.66x[/tex]

And the remainder is:

[tex]r = 100-15\times 6[/tex]

[tex]r = 10[/tex]

4) We multiply the remainder by 10 and divide this result by the denominator to determine the thousandth digit:

[tex]\frac{100}{15} = 6[/tex]

Then,

[tex]\frac{1}{15} = 0.666[/tex]

This question asks us to write a decimal correct to 2 decimal places, which has the characteristic that is infinite periodical decimal. Then, the result correct to 2 decimal places is:

[tex]\frac{1}{15} = 0.\overline{66}[/tex]

326 ÷ 53 Then, check using multiplacation.

They will rest after they hike `2` miles. Then they will hike the remaining `1.75` miles to the lookout. The trail the hikers will use to return from the lookout is `0.5` miles shorter than the trail they will use to go to the lookout. Each hiker will bring `0.25` gallons of water for each mile to and from the lookout. What is the total amount of water each hiker will need to carry?

Answers

Answer:

1.75 gallons

Step-by-step explanation:

First, we need to calculate how far the hike is going up the trail. They first hike 2 miles and then another 1.75 miles after resting so...

2 + 1.75 = 3.75 miles

The trail is 3.75 miles long, the question states that the return path is 0.5 miles shorter, therefore...

3.75 - 0.5 = 3.25 miles

Leaving us with a total hiking distance of

3.75 + 3.25 = 7 miles.

Since each hiker will carry 0.25 gallons for each mile we simply need to multiply this amount by the total number of miles in the hike.

7 * 0.25 = 1.75 gallons

Finally, we can see that each hiker will carry a total of 1.75 gallons of water for the entire hike.

Find an explicit formula for the arithmetic sequence -15, 13, 31, 49

Answers

Answer:

No solution (read below)

Step-by-step explanation:

Formula:

a_n = a_1 + (n-1)d

N is the term #

D is the common difference

First, let's find the common difference.

13 - (-15) = 28

Let's see if that checks out.

31-13 = 18

49 - 31 = 18

18 is not equal to 28

Since there is no common difference you cannot find the equation.

Triangle RST is an equilateral triangle.

Step-by-step explanation:

All three sides of the triangle are of equal length, therefore, because an isosceles triangle is when 2 sides of the triangle are the same length, a scalene triangle being when all sides are of different lengths, and a right triangle having a right angle (a 90 degree angle), this only leaves equilateral, all three sides being the same length, like in the triangle shown.

In baseball, it is 90 feet from home to first base. Knowing this, what would the distance from
home plate to third base be? How did you determine your answer?

Answers

Answer:

270 feet.

Step-by-step explanation:

90 multiplied by three is 270. And a baseball field is square (obvi.) which means from one base to the next would still be 90.

Hope this helps!

Answer:

well 270 if you run all around. but 90 if going straight from home to third.

Step-by-step explanation:

the lines all around are congruent determined by the dashes in the middle so each line is 90 feet, so multiplied by three, you get 270 if running all around.

Miranda sat in the high school computer lab typing like mad. It was 8:30 a.m., and her 1,000-word report on The Catcher in the Rye was due at 9:00. For the past hour, she had been flipping through the ratty pages of the old paperback trying to discern the major plot points and then typing out a few sentences that she hoped were logical. The only reason she was able to get into the lab that early was because she was one of Mrs. Brodys assistants, but a couple of hours in the lab didnt make up for weeks of zoning out in English class.Miranda could kick herself, but she was too busy skimming through her notes and attempting to remember somethinganything!that Mr. Giuffreda had talked about. Mr. Giuffreda was a tough grader, and Miranda did not work well under pressurenot a great combination. On top of all that, Miranda could hear her mothers voice in her head: One more bad grade in English, young lady, and no more soccer team. Miranda failed to see the relationship between soccer and book reports, but she also knew her mother wasnt kidding. When she had slacked off in geometry last semester, her mother had taken away her cell phone for a month. Another time, when Miranda had missed her curfewagain and againshe had gotten grounded for two weeks.Still typing, Miranda thought about Mr. Giuffreda. He expected nothing but the bestand then some. He never gave extensions unless someone had a family emergency, and he had a terrible habit of brushing off even the most creative excuses. Anyway, Miranda didnt need an extra day or two. She needed time to read the entire novel again. Miranda ran a word count361. She checked her watch8:45. She flipped to the end of the book trying desperately to remember the ending, but nothing was coming to her. Why hadnt she paid attention?At 8:55, she had a whopping, miraculous 402 words. The homeroom bell had rung five minutes ago, and students were filing into the lab for first period. Mirandas fingers were still flying, but by 8:59, Mrs. Brody asked Miranda to leave so she could start class on time. Miranda saved her work on her USB drive, collected her pages from the printer, and slung her knapsack over her shoulder.
