Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it took 8 days for the ice to reach a thickness of 3 inches. At what rate was the ice growing over these 8 days in inches per day?

Answers

The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth

The growth rate of the ice over the 8 days is 0.375 inches/day

Reason:

The known information on the ice are;

The time it took the ice to reach a thickness of 3 inches = 8 days

Required:

The (average) rate that the ice is growing in c=inches per day

Solution:

[tex]Rate \ of \ growth \ of \ ice= \dfrac{Increase \ in \ thickness}{ Time} = \dfrac{\Delta \ Thickness}{\Delta T}[/tex]

Therefore;

[tex]Rate \ of \ growth \ of \ ice= \dfrac{3 \ inches}{ 8 \ days} = 0.375 \ inches/day[/tex]

The (average) rate of growth of the ice over the 8 days is 0.375 inches per day

How can you estimaite [tex]\sqrt 40.[/tex]

Answers

9514 1404 393

Answer:

  √40 ≈ 6 4/13 ≈ 6.31

Step-by-step explanation:

The estimate by linear approximation starts with the recognition that ...

  40 = 36 +4 = 6² +4

and the difference from 36 to the next square, 7² = 49 is 49-36 = 13.

The linear approximation to √40 is ...

  √40 ≈ 6 4/13 ≈ 6.31

__

There are various methods for improving this approximation. Perhaps the fastest improvement is obtained using the "Babylonian method." The next iteration is the average of this value and 40 divided by this value.

  (82/13 +40/(82/13))/2 = 6 173/533 ≈ 6.3246 . . . . accurate to 4 decimal places

_____

Additional comment

When you write the value in terms of a square and a remainder:

  n = s² +r

then the above linear approximation of √n can be written as ...

  √n ≈ s +r/(2s+1)

Using the idea that a square root can always be represented by a continued fraction, we can continue the fraction one more iteration to give a slightly better approximation:

  √n ≈ s +r(2s+1)/(2s(2s+1) +r)

For the case at hand, this gives √40 ≈ 6+52/160 = 6 13/40 = 6.325, accurate to 3 decimal places. Additional iterations using the continued fraction idea can be had using ...

  n'' = s + r/(s +n') . . . . . where n' is an approximation of the root and n'' is a better approximation. This does not converge as fast as the Babylonian method, but may be easier to calculate on some calculators.

Answers

Answer:

$158,035.41 rounded to the nearest 10 dollars is $158,040

Step-by-step explanation:

Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place. If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is.

Flowers - Samantha and Maria purchased flowers. Samantha bought five roses for "r" dollars each and four daises for "d" dollars each. Altogether, Samantha spent $32 on flowers. Maria purchased one rose for "r" dollars apiece and six daisies for "d" dollars apiece - spending $22 total.

a) Write a system of equations (two linear equations) using appropriate variables.

b) Solve the system to find the cost of roses and daisies. Use any strategy that you've learned.

Answers

Answer:

part a

[tex]5r + 4d = 32[/tex]

[tex]r + 6d = 22[/tex]

part b

the value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece

Step-by-step explanation:

part a

for part a just denote r for roses and rerecord the question in terms of a function of roses and daisies the right hand side should be the prices or cost

part b

solve the two equations simultaneously or by substitution.

let's do simultaneous

multiply the secondequation by 5

[tex]5r + 4d = 32[/tex]

[tex]5r + 30d = 110[/tex]

subtracting the two,

[tex]26d = 78[/tex]

therefore

[tex]d = 3 dollars[/tex]

find the value of roses,

[tex]5r + 4(3) = 32 \\ 5r = 32 - 12 \\ r = 4[/tex]

The tape diagram represents the ratio of the time you spend tutoring to the time your friend spends tutoring. You tutor for 3 hours. How many hours does your friend spend tutoring?
You
Friend

Answers

Answer:

15 Hours

Step-by-step explanation:

So you have one block, and your friend has two.

We know that you work for 3 hours, this means that your only block must represent 3 hours.

And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.

Then in total, he tutored for 3 hours + 3 hours = 6 hours.

 

Therefore, you still have only one block, but now your friend has 5.

Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:

5*3 hours = 15 hours

What is the inverse of the function f(x) = x +3?

h(x)=1/3x + 3
h(x)=1/3x - 3
h(x)= x - 3
h(x)= x + 3

Answers

Step-by-step explanation:

the inverse function simply calculate the original x it of a given y. so, we need to transform the original function to calculate x instead of y.

and then, at the end to make it a formally correct function definition, we rename x to y and y to x.

y = x + 3

x = y - 3

=> to make it a formally correct function definition

y = x - 3 = h(x)

28. Suppose that the CPI in Year 1 is 150 and the CPI in Year 2 is 200. The rate of
inflation between Year 1 and Year 2 is:
a) 14.28%.
I b) 25%
c) 33.33%
d) 50%

Answers

The rate of inflation between year 1 and year 2, based on the CPI, is  c. 33.33%.

The Consumer Price Index (CPI) allows us to calculate inflation. To find the inflation across these years, use the formula:

= (CPI₂ - CPI₁) / CPI₁ x 100%

Solving gives us:

= (200 - 150) / 150 x 100%

= 33.3%

In conclusion, the inflation is 33.3%.

She was the captain and star athlete of her track and field team. Although Carina wasnt an excellent runner when she first joined the team two years earlier, she practiced all the time and soon began to win almost every race in which she competed. Carina was doing so well that she thought she might become the winningest track and field athlete in her schools history! 2One afternoon at track practice, Coach Winder nabbed everyones attention to introduce a new athlete. This is Roberto," he said. "He just transferred to our school from Greensboro Middle School. Please welcome Roberto to the team! 3The members of the team clapped and jostled each other as they tried to shake Robertos hand. As the team captain, Carina shook Robertos hand first. She introduced herself and told Roberto that she was excited to have another team member. Roberto told Carina that he had been reluctant about joining the team, but Carina assured him that he would have a marvelous time. 4The next day, the members of the track team stretched before running some sprints. Carina told Roberto that he could race with her. Dont worry, she said. Ill go easy on you because its your first practice. 5Carina and Roberto lined up at the starting blocks. When they heard the CRACK of the starting pistol, Roberto and Carina started. After a short distance, Carina realized that Roberto was no longer beside her. She turned to see how far behind he had fallen, but to her amazement, Roberto was not behind her. She looked up and saw Roberto surging ahead. His feet moved as fast as lightning! When Carina realized that she was about to lose, she ran as vigorously as she could; however, it wasnt enough. Roberto triumphed. Carina seemed almost paralyzed with shock, but she managed to smile and congratulate him. 6Over the next few weeks, Roberto became a phenomenon on the track. No matter how hard Carina trained, she could never beat Roberto. 7One evening after a track meet, Carina was desolate. Roberto had won first place, and Carina had come in third! She considered hanging up her running shoes and quitting the team. Just as she was about to call Coach Winder, her father entered the living room. Carina explained her situation to him. 8If winning is so important to you that you cant merely have fun being a member of the team, said Carinas father, then I guess quitting is your only option. But, before you make your decision, think about why you originally joined the team. 9The next day, Carina walked into Coach Winders office and handed him a slip of paper. Coach Winders eyes widened as he read it. Then, he closed the note and shook his head approvingly. 11Thats right, Carina said with a smile, Id like Roberto to serve as co-captain of the team.What is a THEME for this story?A) Having fun is more important than winning.B) When someone does better than you, practice more so you can beat them.C) Never settle for second place.D) If someone is better than you at something, you should just quit.
