As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second. Convert this speed to kilometers

Ira Lisetskai [31]

Answer:

The kilometers Jupiter travel in 5 seconds is 64 kilometers.

Step-by-step explanation:

Given:

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second.

1 mile is equal to 1.6 kilometers.

Now, to convert this speed to kilometers per second, and at this speed to find kilometers will Jupiter travel in 5 seconds.

So, to convert speed of miles per second into kilometres per second:

1 mile = 1.6 kilometres.

Thus, 8 miles = 8 × 1.6 = 12.8 kilometres per second.

Now, at this speed we calculate the kilometres Jupiter travel in 5 seconds by multiplying:

In 1 second Jupiter travel = 12.8 kilometres.

So, in 5 seconds Jupiter travel $=12.8\times 5$

$=64\ kilometers.$

Therefore, the kilometers Jupiter travel in 5 seconds is 64 kilometers.

How to solve this problem?

valentinak56 [21]

Very nice handwriting but the math and English are confusing.

Let's assume we're told

$\displaystyle 45 = \sum_{i=1}^9 (x_i - 10)^2$

The subscript is important.

I think we're told the similar sum with 11 gives the smallest possible value for the sum. This is a rather cagey way of telling us 11 is the mean of the nine points. The mean is the number which minimizes the sum of squared deviations.

$\displaystyle 45 = \sum_{i=1}^9 (x_i - 10)^2 = \sum x_i^2 - 20 \sum x_i + 9(100)$

$\displaystyle \sum x_i^2= 20 \sum x_i - 900$

If 11 is the mean, the sum of the points is 9(11)=99.

$\displaystyle \sum x_i^2= 20 (99) - 900 = 1080$

Answer: 1080

Which of the following give the correct graph and phase shift for y = 3 cos ( θ +20) – 4?

mihalych1998 [28]

Answer:

See picture attached below

Step-by-step explanation:

We can easily find the answer to your question, if we plot the equation with a graphing calculator or any plotting tool.

The equation is

y = 3 cos (θ + 20) - 4

See attached picture below

phase_shift = 20

max_amplitude = -1

min_amplitude = -7

Period = 2π

Tyler reads 2/15 of a book on Monday, 1/3 of it on tuesday, 2/9 of it on Wednesday, and 3/4 of the remainder on thus day. If he

kykrilka [37]

The number of pages in the book is 180

Explanation:

The first thing we should do is to convert these fractions to percentage

$Monday = \frac{2}{15} X 100 = 13.33\\\\Tuesday = \frac{1}{3} X 100 = 33.33%\\\\\\Wednesday = \frac{2}{9} X 100 = 22.22%\\\\\\\\$

3/4 of the remainder on thursday:

Thursday: (100 - (13.33 + 33.33 + 22.22) * (3/4) = 23.33%

he still has 14 pages left to read on friday

Friday: [100 - (13.33 + 33.33 + 22.22) ] - 23.33 = 7.77%

Which means that 14 pages represent 7.77% of the book.

Therefore the number of pages of the book is given by:

$=\frac{100}{7.77} X 14\\\\= 180$

Therefore, number of pages in the book is 180
