The answer will be t=2.50g I think
Answer:
21n
Step-by-step explanation:
1. triple n = 3(n)
3n
3. multiply 7 = 7(3n) = 21n
Answer:
16
Step-by-step explanation:
let the number be x , then
x = 15 ( multiply both sides by 4 to clear the fraction )
3x = 60 ( divide both sides by 3 )
x = 20 , then
× 20 = 4 × 4 = 16
Answer:
The rate of the volume increase will be 
Step-by-step explanation:
Let's take the derivative with respect to time on each side of the volume equation.

Now, we just need to put all the values on the rate equation.
We know that:
dR/dt is 0.04 cm/s
And we need to know what is dV/dt when R = 10 cm.
Therefore using the equation of the volume rate:

The y-intercept which is the point at which x = 0 is; A: -10
<h3>How to find the y-intercept?</h3>
The general form of an equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
We are given the slope;
m = -4
Now, the line passes through the point 0, -10. Thus;
(y - y1)/(x - x1) = -4
(y + 10)/(x - 0) = -4
y + 10 = -4x
y = -4x - 10
Thus, the y-intercept which is the point at which x = 0 is; y = -10
