Answer:
a = 60
b = 90
c = 150
Step-by-step explanation:
Numerele a, b și c sunt direct proporționale cu 2, 3 și 5.
Unde k este constantă de proporționalitate
a ∝ 2
a = 2k
b ∝ 3
b = 3k
c ∝ 5
c = 5k
Dacă media aritmetică a celor trei numere este egală cu 100, determinați numerele a, b și c
= 2k + 3k + 5k / 3 = 100
= 10k / 3 = 100
Cross Multiply
= 10k = 3 × 100
= 10k = 300
Împărțiți ambele părți la 10
k = 300/10
k = 30
Pentru numărul a
a = 2k
a = 2 × 30
a = 60
Pentru numărul b
b = 3k
b = 3 × 30
b = 90
Pentru numărul c
c = 5k
c = 5 × 30
c = 150
Prin urmare, a = 60, b = 90, c = 150
Answer: I think 91.9
Step-by-step explanation:
If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9
Sorry if that’s not right! I just wanted to take a crack at it.
Answer:
"10"
Step-by-step explanation:
This is rather thinking "pictorially". Picture it.
You can match it with a round clock that has numbers 1 - 12 written on it.
So,
32 and 16 would be opposite of each other [top and bottom]. And, 1 - 15 would be on right side and 17 - 31 would be on left side.
Now,
Going counter-clockwise from 32, 26 would be the 6th number. Going counter-clockwise from 16, 10 would be the 6th number.
Hence, they would be opposite of each other.
10 would be opposite of 26
