Answer:
(9 x 10,000,000)+(7 x 100)+(9 x 10)
Answer:
Step-by-step explanation:
x^2 - 10x + 29
x^2 - 10x = -29
x^2 -10x + 25 = -29 + 25
(x - 5)^2 = -4
(x - 5)^2 + 4 <==
Answer:
167.27 mg.
Step-by-step explanation:
We have been given that the half-life of Radium-226 is 1590 years and a sample contains 400 mg.
We will use half life formula to solve our given problem.
, where N(t)= Final amount after t years, 
= Original amount, t/2= half life in years.
Now let us substitute our given values in half-life formula.
Therefore, the remaining amount of Radium-226 after 2000 years will be 167.27 mg.
Answer:
x= 2
Step-by-step explanation:
Given that,
AB = 7.5x
BC = 6x+3
AC = 10x-5
ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,
AC = BC = AB
10x-5 = 6x+3
Taking like terms together
10x-6x = 5+3
4x = 8
x = 2
Hence, the value of x is equal to 2.
