Volume of a cylinder: V=πr^2h solve for r

tangare [24]

In the formula Volume of a cylinder: V=πr^2h to solve for x, the equation is r=√V/πh. To turn the orginal formula to r, divide both sides by π and do the same for h, then take ±√ from both sides. Finally, r is not negative so it will be positive.

Plzzzzzzzz! A suitcase lock has a code 4 symbols long. The symbols on the lock are a star, a square, a circle, a triangle, a lin

34kurt

Answer:

$\dfrac{1}{30}$

Step-by-step explanation:

6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:

6•5•4•3 = 360

If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.

So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:

1•1•4•3 = 12

The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:

$\dfrac{1\cdot1\cdot4\cdot3}{6\cdot5\cdot4\cdot3}=\dfrac{1\cdot1}{6\cdot5}=\dfrac{1}{30}$

Study the example on the right to help you complete the problem below. please help!:(

Answer : The equation for 'h' is $h=\frac{2A}{b}$

Step-by-step explanation :

The given equation is:

$A=\frac{1}{2}bh$

Now we have to determine the equation for 'h'.

$A=\frac{1}{2}bh$

Multiplying the equation by 2.

$2\times A=2\times \frac{1}{2}\times bh$

on simplifying, we get:

$2\times A=bh$

Dividing the equation by 'b'.

$\frac{2\times A}{b}=\frac{bh}{b}$

$\frac{2\times A}{b}=h$

or,

$h=\frac{2A}{b}$

Therefore, the equation for 'h' is $h=\frac{2A}{b}$

Royce had 171.26 in digital Money.so far this month he has made deposits of $60.76, 29.79 and $89.31 into his account, while he

Nesterboy [21]

Answer:

$\$234.02$

Step-by-step explanation:

we know that

The amount Royce had plus the amounts deposited minus the amounts withdrawn is equal to the amount Royce currently has now

so

Let

x ----> the amount Royce currently has now

$x=171.26+(60.76+29.79+89.31)-(14.82+46.76+55.52)$

$x=171.26+(179.86)-(117.1)$

$x=\$234.02$
