I'll do the first page.

ANYONE PLEASE HELP!!
lapo4ka [179]

Answer:

A

Step-by-step explanation:

Corresponding angles are angles that you can follow down the transversal and they will land in the same spot on the other parallel line.  Look at angle 8.  It is the bottom left angle in the group of 4 angles around it.  If you slide it to the left it would land right on top of angle 4 which is also in the bottom left of its group of 4 angles.

You can do the same thing taking angle 8 down to angle 12.

the volume v of a tank varies directly with its height h a tank 12 ft High holds 300 cubic feet write an equation relating v &am
Liula [17]

v varies directly with height means

v/h=k were k is a constant

or also h/v=k where k is a constant (this is a different k than previous)

so if h=12 and v=300 then

h/v=12/300=1/25=k

so the relationhip could be h/v=1/25


if you di v/h, then

v/h=300/12=25/1=25=k

so the relationship could be v/h=25
