Answer:
t = 54.85714 seconds
Step-by-step explanation:
t = 12(210)+9000/210
t = (2520 + 9000) / 210
t = 11520 / 210
t = 54.85714 seconds
Answer:
<h2>A) 3 cm</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
We have r = 1cm and H = 21cm. Substitute:

The formula of a cone:

r - radius
H - height
We have V = 21π cm³ and H = 7cm. Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 7</em>
<em>multiply both sides by 3</em>

Answer:
So the statement:
"The product of two irrational numbers is rational." is false.
Step-by-step explanation:
The product of two irrationals can be irrational or rational.
Example:

is irrational but when you multiply it to itself the output is rational.
Example:

are irrational and when you multiply them you get an irrational answer of
.
So the statement:
"The product of two irrational numbers is rational." is false.
Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
Nope problem how do I do this
