Answer:

C

Step-by-step explanation:

time is directly proportional to the number of problems in the set

=> x = ky

k = constant of proportionality

when k = 12

x = 12y

by making y the subject, we divide both sides by 12

=> y = x/12

Levart [38]

Answer:

Step-by-step explanation:

The angle opposite the 10 meter length is greater than 90. It calculates out to be about 130 degrees. The triangle is obtuse.

As a note that dog is going to be very uncomfortable. He does not have much room to move around. Let's hope he's something like a Chihuahua.  The height of the triangle from the 130 degree angle's apex is about 2 meters.
