Let the total amount of pages be t
t=30+1/8t+2/8t
now simplify
t=30+3/8t
5/8t=30
divide 30 by 5
1/8=6
now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
X^6= 3^12
(X^6) ^1/6. = (3^12)^1/6
X=9
Answer:
any, equal
Step-by-step explanation:
A Simple Random Sample reflects that any individual in the population has an equal chance of being selected.
Answer:
area= 41 cm^2
Step-by-step explanation:
area=5 x 8.2 = 41 cm^2
divide the rhombus in half either way and you have two identical triangles.
area of triangle =0.5 x base x height
double that for the two triangles and you have the area of the rhombus.
First, square both sides. This will cancel out the radical.
(a^2 = b + 6)
Then subtract 6 from both sides
b = a^2 - 6
