Let's say each row sums to 15
If we had 3 rows, then the total sum would be 3*15 = 45
If we added all of the values in the 3x3 magic square, then we'd get 45 as well.
This is one example showing that
sum of all values = (number of rows)*(magic constant)
You can replace "rows" with columns to get the same idea, because each column also adds to the same magic constant. The diagonals are an exception since we only have two of them.
Answer: Depends on the elephant ;)
Answer:
Step-by-step explanation:
fun one - thanx 4 posting!!!
let the interaction of BK and NO be P
and NO be x
triangle NBO n ABC are similar by AAA as NO // AC
so BP/BK=NO/AC=x/30
BP=10*x/30=x/3
PK=height of triangle NMO
cuz' NM=MO n m∠NMO=90°
height of triangle NMO=NO/2=x/2
PK=x/2
area of triangle NBO + area ot trapezoid NOCA = area of triangle ABC
BP*NO/2 + (NO+AC)*PK/2 = BK*AC/2
(x/3)*x/2+(x+30)*x/2 = 10*30/2
simplifying x^2/6+x^2/4+30x/4=150
5x^2+90x-1800=0
solving x=12 or x=-30
as length cannot be negative
NO=12
Answer: 3 toys
Step-by-step explanation:
equation will be 60 - 5 x t = 45
solving it we get
5 x t = 60 - 45 = 15
=> t = 15/5 = 3
I think your answer should be s^0
