Answer:
$618.95 rounded up. 0.004c
£388.09 on rent and $230.84 food
We can round up and state $619 to nearest tenth.
Or leave as non rounded Total $618.93
Step-by-step explanation:
27% of 1,437.40=388.09
1,437.40 - 388.09 = 1049.31
22% of 1049.31 = 230.8482
$230,84 Shown here, as not round up or down as 230.84 as £388.09 was not rounded up from 388.098.
= $618.95 rounded up. 0.004c
3.1415... is not a rational number because it is continuous.
Hope I helped :)

Answer:
91.6 km/h
Step-by-step explanation:
Let v = average speed of van = 65 km/h and v' = average speed of car. Let t be the time the car starts to move. The van started 35 minutes earlier at t' = (t + 35/60) h.
Since distance d = vt where v = velocity and t = time, the distance moved by the van d = vt' = v(t + 35/60) and that moved by the car is d' = v't.
Since the car catches up with the van after it had moved a distance of 130 km, d = d' = 130 km.
So d = v(t + 0.583)
Substituting d = 130 km and v = 65 km/h, we have
130 km = 65 km/h(t + 0.583)
130 km = (65t + 37.895 )km
subtracting 37.895 from both sides, we have
130 km - 37.895 km = 65t
92.105 = 65t
dividing both sides by 65, we have
t = 92.105/65
= 1.417 h
≅ 1.42 h
Since d = d' = v't,
v' = d'/t
= 130 km/1.42 h
= 91.55 km/h
≅ 91.6 km/h
So, the average speed of the car is 91.6 km/h
