Question of the day:Math question!!!!!

If one day in heaven = 1,000 yrs on earth, and gabes lips are on the horn and it takes him 3 seconds to blow, how many days do we have left on earth?

Answers

Answer 1
Answer:

Answer:

  12 days 16 hours 22 minutes 7.5 seconds

Step-by-step explanation:

You are interested in the proportion ...

  earth time / heaven time = (1000 years)/(1 day) = (x days)/(3 seconds)

Multiplying by 3 seconds, we find ...

  x days = (3 seconds)(1000 years)/(1 day)

If we convert 1000 years to days, then the formula will give us "x days" as a number of seconds.

1000 years is a long enough time period that all of the leap-year rules come into play. So, we will use the average number of days in a year as 365.2425. Then 1000 years is 365,242.5 days, and we get ...

  x days = (3 seconds)(354,242.5) = 1,095,727.5 seconds

There are 3600 seconds in 1 hour, so this is ...

  x days = (1095727.5 s)/(3600 s/h) = 304.36875 h

The fraction of an hour converts to 22 minutes 7.5 seconds. The 304 hours converts to 12 days 16 hours.

When Gabe starts blowing his horn, we have 12 days 16 hours 22 minutes 7.5 seconds left on Earth.

_____

The number of minutes and seconds will vary, depending on what you consider to be the number of days in a year.

For her cell phone plan, Heather pays $30 per month plus $0.05 per text. She wants to keep her bill under $60 per month. Which inequality represents the number of texts, t, Heather can send each month while staying within her budget? A)t < 600. B) t > 600. C) t < 1,800. D) t > 1,800

Answers

so 30+0.05t<60 is the equation so
subtract 30 from both sides
0.05t<30
multiply by 100
5t<3000
divide by 5
t<600
she can send less than 600 texts to stay below 60 dollars
so the answer is B

Savannah is 24 years older than Ryan, while Sebastian is 5 times as old as Ryan. If Savannah and Sebastian are twins, which equation may be used to determine the age of all three people?A) 8x = 24
B) 24 + 2x = 5x
C) 24 + 5x = x
D) 24 + x = 5x

Answers

Answer:

The correct answer is D) 24 + x = 5x

Step-by-step explanation:

Since they are twins, we know they are the same age. Since Savannah is 24 years older than Ryan, we can model it as 24 + x, where x is Ryan's age.

Since Sebastian is five times as old as Ryan, we can model it as 5x.

Now, we can set them equal to each other.

24 + x = 5x

For Each Data Set, Determine the median, the first and third Quartiles, and the interquartile Range.1. Texts per day: 24, 53, 38, 12, 31, 19, 26
2. Daily Attendance at the water park: 346, 250, 433, 369, 422, 298 this is 45 points! :D

Answers

1. First of all arrange the data set in either ascending or descending order.
12, 19, 24, 26, 31, 38, 53.  N = 7 (number of data items)
Median position = 1/2(N + 1)th item = 1/2(7 + 1)th item = 1/2(8)th item = 4th item = 26
First quatile = 1/4(N + 1)th item = 1/4(7 + 1)th item = 1/4(8)th item = 2nd item = 19
Third quatile = 3/4(N + 1)th item = 3/4(7 + 1)th item = 3/4(8)th item = 6th item = 38
Interquatile range = Third quartile - first quatile = 38 - 19 = 19
