I can't see the graph but let's use logic
hmm, more than 10 cubic feet of topsoil so the first and 2nd options are wrong
let's ee the costs
3rd option
10*1=10
2*12=24
10+24=34 and 34<50, that is fine
4th option
3*10=30
2*12=24
30+24=54
54>50, nope, that is over cost
answer is 3rd one
the one with 1 cubic yard compost and 12 cubic yard topsoil
36 is the answer you are looking for.
Step-by-step explanation:
x + x + x = 90°
3x = 90°
x = 90/3 = 30
x = 30°
now,
apply angle sum property to find the value of y
as, x = 30
so,
30 + 90 + y = 180
120 + y = 180
y = 180 - 120 = 60
y = 60° ans.
therefore, option B is correct
hope this answer helps you!
Answer:
2:1
Step-by-step explanation:
average age of both = 40
average age of teachers = 35
average age of professors = 50
35 + 35 + 50 = 120
120 / 3 = 40
