Answer:
415.63 minutes
Step-by-step explanation:
Growth can be represented by the equation
. We can find the rate at which it grows by using t=25 minutes and
or double the amount at that time. The first step we always take is to divide
by A.
To solve for r, we will take the natural log of both sides and use log rules to isolate r.
We know
so we were able to cancel it out and divide both sides by 25.
We solve with a calculator
We change 0.0277 into a percent by multiplying by 100 to get 2.77% as the rate.
The equation is
.
We repeat the step above substituting A=5,000,000,
=50, and r=0.02777. Then solve for t.

t=415.63 minutes
Answer:
x=2, y=4
Step-by-step explanation:
When using elimination, the objective is to elimate one variable. In this case, we see that "y" can easily be eliminated by adding the two equations together since you will get 3y + (-3y) which will eliminate y because the value would become 0, letting us solve for x.

Then we get
, because the y's will eliminated, and 8x+7x is 15x, and 28+2 is 30.
Then divide by 15 on both sides and you get x=2
If x=2, then we can substitute that value into any of the previous given equations and find the value of y.
8×2 +3y = 28
16+3y=28
3y=12
y=4
So the answer to your system of equations would be x=2, and y=4
You can substitute the answers we found to see that they satisfy the equation.
Hope this helped.

Answer:
<em><u>The answer here is 3/25, more left handed students.</u></em>
Step-by-step explanation:
12/100 are left handed, which reduces to 3/25. This means that there are only 3 left handed kids for every 22 right handed kids, showing that there are more right handed students than left handed.
