Answer:
The answer is below
Step-by-step explanation:
Let x represent a first place finish, y represent a second place finish and z represent a third place finish.
Since there is a total of 20 individual events, hence:
x + y + z = 20 (1)
A first place finish is 5 point, a second place finish is 3 point and third place finish is 1 point. Therefore:
5x + 3y + z = 68 (2)
The second place finishers is as much as first and third-place finishers combined. Hence:
y = x + z (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = 7, y = 10 and z = 3
This means the number of first place finishes was 7, second place finishes was 10 and third place finishes was 3
27,36,45 all are numbers bigger than 20
Answer:
B) 36
BA=CD
BA=9
AREA OF TRIANGLE ABC=1/2×b×h
63=1/2×b×9
126=b×9
b=14
BC=14
AD=BC
AE+ED=BC
AE=BC-ED
AE=14-6
AE=8
AREA OF TRIANGLE ACE= 1/2×AE×CD
= 1/2×8×9
=36
If 30% is 32000 kilobytes, then 100% would be 32000 / 30%, or 32000/0.3 which equals 106,666.6666(6), which equals approximately 106 megabytes.
