Step-by-step explanation:
45 is the answer for the question
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
13. Is 18
15. Is 86
17 is 5
19 is 15
21 is 24
23 is 29
Answer:
Step-by-step explanation:
Step 1 Answer: Yes, 3
Step 2 Answer: Yes, 5
Step 3 Answer: No
On an isosceles trapezoid, the two sides that are not parallel to each other will be exactly the same length. If this is true, than it would be create a symetric trapezoid. The diagonals would be the same length. The bases of any trapezoid are parallel, so this is true. The diagonals cannot possibly be perpendicular because the 2 nonparallel sides would be slanted. So, the answer is the 3rd choice.
