Answer:
5y = x
Step-by-step explanation:
15 miles = 3 hours
Divide by 3 on both sides to find how many miles he/she can run in 1 hour.
15 miles = 3 hours ⇒ 5 miles = 1 hour
Therefore, the equation is just 5y = x.

Answer:
Given:
perpendicular [p]=9cm
base[b]=15cm
length[l]=4cm
we have
the volume of this triangular prism=area of traingle. ×length=1/2 p×b×l
=½×9×15×4=270cm³
270cm³ is a required volume.
5. The way I do these problems is setting up the equation as follows:
P1V1/T1 = P2V2/T2
The units of volume and pressure can be substituted as given, since they are in relation to one another, however, the final answer must match the units provided in the question. Also, temperature must be converted to Kelvins before the equation can be used.
V1 = 50 cm^3
P1 = 825 Hg/mm
T1 = 15C = 288K
P2 = 750 Hg/mm
T2 = 47C = 320K
V2 = ?
Solve:
P1V1/T1 = P2V2/T2
(825)(50)/(288) = (750)V2/(320)
143.23 = 2.34V2
V2 = 61.21 cm^3
Since 90 is the mean, the z-score of the mean is always 0.
