10 grams Vanadium will be left after 48 days
Further explanation:
Half-life is the time after which the chemical is reduced to half.
The reaming mass after half life is given by:
The formula for calculating the remaining mass after given time period is:
Here n is the number of half lives passed
Now,
Given
Mass=80 grams
Time= 48 days
Half-life = 16 days
The number of half lives will be:
Putting the values of n and mass in the formula
10 grams Vanadium will be left after 48 days
Keywords: Half-life, radioactive

Answer:
x = 120
y = 30
Step-by-step explanation:
Given that RST is equilateral, each of its interior angles will be 60 degrees
Looking at x, it lies on a starting line with one of the interior angles of RST
The sum of angles on a straight line is 180
Thus;
x + 60 = 180
x = 180-60
x= 120
Looking at triangle RSU, the markings indicates that we have an isosceles triangle
For an isosceles triangle, the base angles are equal in value
This means that SRU is also y
Mathematically, the sum of angles in a triangle is 180
Hence;
x + y + y = 180
x + 2y = 180
120 + 2y= 180
2y = 180-120
2y = 60
y = 60/2
y = 30
Answer:
I have to text you here cuz it dosent let me txt you in other place
The number of people who grow potatoes is 3 times the number that grow sugar beet.
⇒ 48 + x = 3( x + 12)
--------------------------------------------
Solve for x :
--------------------------------------------
48 + x = 3( x + 12)
48 + x = 3x + 36
2x = 12
x = 6
--------------------------------------------
People who do both grow either.
--------------------------------------------
Number of people who does not grow potato or sugar beets = 100 - 48 - 12 - 6 = 34
------------------------------------------------------------------------------
Answer: The answers are 6 and 34.
------------------------------------------------------------------------------
"6" is inbetween "48" and "12".
"34" is outside the two circles.
