If a cylindrical tank holds 100,00 gallons of water which can be drained from thebottom of the tank in an hour, then Torricelli’
tatyana61 [14]

Answer:

First, I think the right formula is:

V(t) = 100,000(1-\frac{t}{60} ),20\leq t\leq 60

A) We first derive the formula given above:

V'(t)=-\frac{100000}{60}

V'(t) represent the drain rate of the tank volume.

B) the units is: gallons/time

C) at V'(10) = 100000/60 = 1666.66 gallons/time.

because the formula V'(t) is constant so it doesn't depend of time.

Vertical angle of isoceles triangle is 50° while it's base angles are together 2x .find x
Ghella [55]

Answer:

The sum of all the angles of an isoceles triangle is 180°

So it's 50° + 2x° = 180°

50 + 2x = 180

2x = 180 - 50

2x = 130

x = 130/2

x = 65
