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 <u>64 kilometers</u>.

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:

<em>1 mile = 1.6 kilometres.</em>

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:

<em>In 1 second Jupiter travel = 12.8 kilometres.</em>

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

$=64\ kilometers.$

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

An art teacher needs to buy at least 60 brushes for her class. The brushes are sold in packs of 8. In which inequality does n re

VikaD [51]

Answer:

$n\leq 8$

Step-by-step explanation:

Given: An art teacher needs to buy at least 60 brushes for her class.

Number of brushes in each pack is equal to 8.

To find: inequality where n represent the minimum number of packs the teacher needs to buy for her class

Solution:

Total number of brushes $\leq 60$

Also,

Total number of brushes = $8n$ where n represent the minimum number of packs the teacher needs to buy for her class

According to question,

$8n\leq 60\\n\leq \frac{60}{8}\\=7.5\\\approx 8$

The regression line has been fitted to the data points (4, 8), (2, 5), and (1, 2). the sum of the squared residuals will be:____

Inessa [10]

Based on the regression line, and the data points, the sum of squared residuals is 22.

<h3>What is the sum of squared residuals?</h3>

The squared residual can be found as:

= (y - 3 + 2x)²

For point (4 , 8)

= (8 - 3 - 2(4))²

= 9

For point (2 , 5)

= (5 - 3 - 2(2))²

= 4

For point (1, 2)

= (2 - 3 - 2(1))²

= 9

The sum of squared residuals is:

= 9 + 4 + 9

= 22

Full question is:

The regression line = 3 + 2x has been fitted to the data points (4,8), (2,5), and (1,2). The residual sum of squares will be:

Every day, Savannah's burrito stand uses 3 bags of tortillas. How many days will 3/4 of a bag of tortillas last?

Darina [25.2K]

Answer:

Step-by-step explanation:

Set up a ratio.

3 bags/1 day = 2/3 bag/x day

Cross multiply to solve.

3x=2/3

So x=2/3(1/3)=2/9 of a day
