Answer:
around 13.18
Step-by-step explanation:
the middle square is 2*2 = 4
the triangle then is 2^2 + 6^2 = 40 -> sqrt40 = 6.325
and then 2^2 + 2^2 = 8 -> sqrt8 = 2.828
4+6.325+2.828 = 13.18
Answer:
5.429503679 multiply by 10 power 12th
Answer:
9 tickets
Step-by-step explanation:
Let x = the number of tickets
let y = the total she spends
So y = 5 + 8 + 0.75x
If the max she can spend is 20, set y = 20 and solve for x:
5 + 8 + 0.75x = 20
13 + 0.75x = 20
0.75x = 20 - 13
0.75x = 7
x = 7 ÷ 0.75 = 9.333333333
Therefore, the max number of tickets that can be bough is 9
Its 15% because you have to divide 270 by 1800
