Answer:
13.5 mg
Step-by-step explanation:
Here given Cobalt isotope has half life of 5.3 years.
Initial amount is 50 mg.
Given time(10 years) is roughly equals to two half life.
So, after 5.3 year 25 mg of isotope will left further in next half life only around 12.5 mg remains.
Among options 13.5 mg is the best possible
Let x be the number of rows and y be the number of trees per row.
x* y = 112
and y = 2x - 2
from first equation y = 112/x
so 112/x = 2x - 2
112 = 2x^2 - 2x
2x^2 - 2x - 112 = 0
x^2 - x - 56 = 0
(x - 8)(x + 7) = 0
x = 8 , - 7 (ignore the negative)
so the number of rows = 8
and number of trees per row = 112/8 = 14
Answer number of rows = 8 and number trees i each row = 14.
Answer:
D. 15G > 9
Step-by-step explanation:
Given: G = 3/5
Here we have to check each options and find which is true.
Let's start from A.
G - 1 > 2/5
G > 2/5 + 1
G > 7/5 is not true.
B. -10G > 6
Dividing both sides by -10 , we get
G < -6/10
G < -3/5 Is not true.
C. 1 2/5 + G > 3
Now convert 1 2/5 to improper fraction.
1 2/5 = 7/5
7/5 + G > 3
G > 3 - 7/5
G > (15 - 7)/5
G > 8/5 is not rule.
D. 15G > 9
Dividing both sides by 15, we get
G > 9/15
Now we have to simplify 9/15
G > 3/5 which is true.
Answer: D. 15G > 9

Had a question like this before
Answer:
The greatest y-intercept c = 6
Step-by-step explanation:
we know that
slope-intercept form y = mx +c
a) Given that f(x) = 
comparing y = mx +c
slope of the line m = 6 and Y - intercept c= 1/6
b) Given that f(x) = 
y = 6x -6
comparing y = mx +c
slope of the line m = 6 and Y - intercept c= -6
c)
Given that f(x) = 
y =
comparing y = mx +c
slope of the line m = 
and Y - intercept c= 6 ( greatest intercept)
d)
Given that 6 k(x) = x
k(x) = 
y =
comparing y = m x +c
The slope of the line m = and Y-intercept c=0
<u><em>Final answer:-</em></u>
The greatest y-intercept c = 6
