If point E is the midpoint of segment AC and point D is the midpoint of segment BC, which expression represents the value of u? A. u equals p over q

B. u = 1/2s

C. u equals q over p

D. u = 2s

If D and E are mid points of sides BC and AC , then according to mid point theorem, the line ED will be parallel to line AB.

so,

Angle CED = Angle CAB

Angle CDE = Angle CBA

(by corresponding Angle pair)

now the two corresponding angles of Triangle CDE is similar to Triangle CBA, so they are similar by AA similarity.

hence, their corresponding sides are proportional

that is :

and we know that q = t , since D is midpoint of BC.

therefore it will be :

Correct choice is D

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
