Answer:
x = 5.5 (nearest tenth)
Step-by-step explanation:
let x be the length of 1 side
given area of square poster is 30 in²
and
Area = (length of 1 side )²
hence
30 = x²
x = √30
x = 5.4772
x = 5.5 (nearest tenth)
Answer:
18
Step-by-step explanation:
Given
4(n - 4) + 14 ← substitute n = 5 into the expression
= 4(5 - 4) + 14
= 4(1) + 14
= 4 + 14
= 18
26+32=58
58 divided by 10 is abt 5.something
The rest 8 students also needs to go, so it is 5+1=6 vans.
Answer:
Boys - 36$ 33 cents
Girls - 72$ 67 cents
Step-by-step explanation:
Boys x
Girls 2x
Total 109
2x+x=109
3x=109/:3
X=36,3333
Boys x =36$ 33c
Girls 2x= 72,666= 72$ 67c
3/5 and 6/8 are not proportional as even though 3 goes into 6 evenly, 5 does not go into 8 evenly so that makes it disproportional.
