Answer:
It will take 13.58 minutes until there are 80 grams of the element remaining
Step-by-step explanation:
An element with a mass of 990 grams decays by 16.9% per minute.
We are supposed to find how long will it be until there are 80 grams of the element remaining
Formula :
N(t)=Amount after t minutes
=Initial amount
r = rate of decrease = 0.169
t = time in minutes
Substitute the values in the formula :


t=13.58
Hence It will take 13.58 minutes until there are 80 grams of the element remaining
The formula for the surface area of a cube is: SA= 6((length of side)^2).
So if the surface area is 96, first divide by 6. And you get 16. Next you find the square-root of 16 and get 4. So the length of each side is 4 inches.
The formula for volume of a cube is V=(length of side)^3.
So 4 raised to the third power is: 4*4*4.
The volume of the cube is 64 inches cubed.
Answer:
there would be 52 more girls I think
Step-by-step explanation:
let x = multiplier then
31x =number of boys
44x = number of girls
Boys + girls = 300
44x + 31x =300
75x = 300
x = 300/75
x = 4 is the multiplier
therefore:
44*4 = 176 girls
31*4 = 124 boys
dif = 52 more girls than boys
hope this helped :)
