Answer:

10 minutes

Explanation:

Given:

Given:Speed of bus excluding stoppages =54 km/h

Speed of bus including stoppages = 45 km/h

To calculate: Minutes/per hour the bus stopped = ?

Distance covered by bus without stopping =54 km/h

Distance covered by bus with stopping =45 km/h

Due to stoppages it could

9km (54-45km) less

Time taken to cover 9 km=?

time \: taken \: = \frac{distane}{speed }timetaken=

speed

distane

Distance=9km

Speed = 54km/h.

Substituting given values on the above formula we get,

time \: taken \: = \frac{9}{54} hour = \frac{1}{6} hour \:timetaken=

hour=

hour

=10 minutes

Hence,the correct answer is 10 minutes.

Answer:

Distance traveled during this acceleration will be 6950 m

Explanation:

Wear have given maximum speed tat will be equal to final speed of the car v = 278 m/sec

Constant acceleration $a=5.56m/sec^2$

As the car starts initially starts from rest so initial velocity of the car u = 0 m/sec

From third equation of motion $v^2=u^2+2as$

Putting all values in equation

$278^2=0^2+2\times 5.56\times s$

s = 6950 m

So distance traveled during this acceleration will be 6950 m

r-ruslan [8.4K]

Answer:

To summarize and analyze data with both a crosstabulation and charting, Excel typically pair PivotCharts with PivotTables (option b)

Explanation:

Pivot Tables allows us to deal with a high volume of data. This kind of tables are mainly designed to summarize, analyze and explore data in a simple way. Meanwhile, Pivot Charts gives the possibility to visualize the summarizing data provided in PivotTables, enabling the detection of trends, correlations,comparisons and so on. Because of that Pivot tables and pivot charts are usefull and complementary tools of Excel.

Summarizing, the proper option is b.

zvonat [6]

Answer: h = 3.34 m

Explanation:

If the hat is thrown straight up, then at its highest point it has no motion and no kinetic energy. All energy is potential energy

PE = mgh

h = PE/mg = 4.92 / (0.150(9.81)) = 3.34352... ≈3.34 m
