Answer:
I think 80
Step-by-step explanation:
100/15=6.66666667
12x6.67=80.4
Linear dimensions will be in the ratio
12/18 = 2/3
areas (all of them) will have the ratio
4/9
volumes will have the ratio 8/27
Answer: 8 First class tickets
Step-by-step explanation:
You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:
330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)
x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:
330x + 1220(17 - x) = 12730
330x + 20740 - 1220x = 12730
-890x + 20740 = 12730
-890x = -8010
x = 9
Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:
9 + y = 17
y = 8
Sarah bought y = 8 first class tickets.
Answer:
The abbreviation of the postulate which can be used to support the conclusion is SAS ( Side Angle Side )
Step-by-step explanation:
Given : WS = NT, AS = OT, S = T
Now, two sides are given to be equal and one angle
So, the similarity postulate which can be used to support the conclusion can be SAS ( Side Angle Side ). But for this postulate to be used, The angle must lie between the two equal sides.
So, the abbreviation of the postulate which can be used to support the conclusion is SAS ( Side Angle Side )
