Answer:
I don't understand this Qu?estion
Step-by-step explanation:
Just plug in 500 for p, 0.2 for r (because 20% is equivalent to 0.20), and 2 for t:

So, if you start with $500 and charge an interest rate of 20% for 2 years, you will gain $200 to get $700 in total.
Okay so first we need to find the height ofn one hay barrel. To do this we must use the equations v= h×w×l
We already know 3 out of the 4 variables in the equations, in this case we are given the volume so we must work backwards.
The equation will look like this:

First we must mulitpy 4 and 1 1/3 to get 16/3. The equation will now look like:

Next divide 16/3 from h then from 10 2/3 to get :

The height is 2ft. Finally multiply 2 by the number of hay barrels (8) placed upon each other becuase we're finding the height and you will get your answer of 16 ft in height.
Answer:
μv =
σv= 
Step-by-step explanation:
Volume is found by multiplying the area and height. Since we're given both area and height of 10 and 5 cm respectively then
μv =A.h= 10*5= 50 cm^{3}
The standard deviation of the volume will be
σv= 0.3*10= 
<span>So we have a problem with two unknows and one equation. We have to express one over the other like this: 7a - 2b = 5a + b. First we separate one kind on the left side and the other kind on the right side: 7a - 5a = b + 2b. Then: 2a = 3b. Now we divide both sides by 2 and get: a= 3b/2.</span>
