Answer:

t = 14.1 hours

Step-by-step explanation:

Given information: r = 45.9 m/h and d = 647.19 m.

The given formula is

d=rt

where d is the distance in miles, r is the rate, and t is the time in hours.

We need to find the value of t for the given data.

Substitute r = 45.9 and d = 647.19 in above formula.

647.19=(45.9)t

Divide both sides by 45.9 to find the value of t.

\frac{647.19}{45.9}=\frac{45.9t}{45.9}

14.1=t

Therefore the value of t is 14.1 hours for r = 45.9 m/h and d = 647.19 m.

The answer is 14.1 h


d=rt      so          t=d/r

t=647.19/45.9

t=14.1 h

Alright, here goes:
For this question, you are asked about the median and Interquartile Range(IQR), so first you need to understand what that means.
The IQR is the box in the middle of the box-and-whisker-plot. The question asks for the place to have a small IQR, so the most likely places are Pensacola and Jacksonville.
The question is also asking for a high median temperature. The median is the line in the middle of the plot.
The median of Pensacola's plot is higher than the median of Jacksonville, so Pensacola Beach is your answer :)

Find the value of x.<br><br>• 5<br>• 20<br>• 40<br>• 45​
insens350 [35]

Answer:

3rd option: x= 40

Step-by-step explanation:

4x° +20°= 180° (adj. ∠s on a str. line)

<em>Bringing</em><em> </em><em>constants</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>:</em>

4x°= 180° -20°

<em>Simplify</em><em>:</em>

4x°= 160°

<em>Divide</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

x°= 40°

Thus, x=40.
