37.8121

Step-by-step explanation:

you take 34.69$ and multiply it by 1.09

Step-by-step explanation:

Here we will show you step-by-step with explanation how to convert 34.69 decimal hours to hours and minutes.

First, note that 34.69 hours and 34:69 is not the same. 34.69 hours with the decimal point is 34.69 hours in terms of hours. 34:69 with the colon is 34 hours and 69 minutes.

We start by dividing up what is before and after the decimal point like so:

34 = hours

.69 = fractional hours.

To convert from 34.69 decimal hours to hours and minutes, we need to convert the .69 fractional hours to minutes.

Since there are 60 minutes in an hour, you multiply the .69 fractional hours by 60 to get minutes:

.69 x 60 = 41.4 minutes.

Therefore, the answer to "What is 34.69 decimal hours in hours and minutes?" is:

34 hours and 41.4 minutes

12.5 feet

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
