Answer:
Number of total bees = 400
Step-by-step explanation:
He catches 100 bees from the hive and marks each one with a dye.
He later catches 60 and 15 were marked with the dye.
Its very to estimate from the data given.
I'll answer it with ratio.
We'll ratio number of bees with dye to total he caught the second day.
I.e 15:60 = 1:4
We'll multiply this ratio with the number he caught the first day to know the total.
1/4x =100
X = 100*4
X= 400
Where x is the total number of bees in the bee hive.
A1 = -7, an = 4(an - 1)
a2 = 4a1 = 4(-7) = -28
a3 = 4a2 = 4(-28) = -112
Therefore, the first six terms are -28, -112, -448, -1792, -7168, -28,672
Answer:
Infinite
Step-by-step explanation:
2(x-6)+2x=4(x-3) would turn into:
2x-12+2x=4x-12 which would turn into:
4x-12=4x-12 then you could keep going if you wanted:
add 12 to both sides and subtract 4x from both sides:
0=0 (and zero does equal zero so it is unlimited solutions)
1+2+3+... +n=
((1+n) x n) /2
is that the things you want
Answer:
20/21.
Step-by-step explanation:
tan X = opposite side / adjacent side
= 20/21.
