Round 42.621 to the nearest one

2 answers:

5 0

The answer would be 43 because when you have a number that is over 5 to the right of the number you want to round, in this case it is the 2, you round up. so because there is a 6, it is above 5, the 2 would go up to a 3.

The volume of a cone is 18π cubic feet. If the height of the cone is 6 ft, what is the radius of the cone? (V = 1 3 πr2h)

svetoff [14.1K]

Answer:

Volume = 1/3πr^2h

18π = 1/3πr^2 x 6

18 = 2r^2

9 = r^2

r = 3 ft.

Hope this helps you!

Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly?

Aneli [31]

Answer:

The required equation is $x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$ .

Step-by-step explanation:

If a quadratic equation is $ax^2+bx+c=0$ , then the quadratic formula is

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given quadratic equation is

$x^2-9x-20=0$

Here, a=1, b=-9 and c=-20.

Substitute a=1, b=-9 and c=-20 in the above quadratic formula.

$x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$

Therefore the required equation is $x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$ .

2/3 minus 5/8 what’s the answer

Rama09 [41]

Hey there!

$\frac{2}{3}$ $-$ $\frac{5}{8}$
Change the " $subtract$ " symbol to a $addition$ symbol
$\frac{2}{3} + \frac{-5}{8}$
$(-5)(3)$ $= -15$
$2(8)$ $=16$
$3$ $(8)$ $=$ $24$
$\frac{16}{24} + \frac{-15}{24}$
Add " $16 + (-15)$ " together
$\frac{16+ (-15)}{24}$
$16 + (-15)$ $= 1$
$24$ $= 24$
Therefore, $\boxed{Answer: \frac{1}{24} }$

Good luck on your assignment and enjoy your day!

suppose that you put $2,500 into retirement account that grows with an interest rate of 5.25 % compounded once each year after h

Jlenok [28]

You will need to use this formula:
Years = {log(total) -log(Principal)} ÷ log(1 + rate)
Years = [log(15,000) - log(2,500)] / log (1.0525)

 4.1760912591 - 3.3979400087 / 0.0222221045 =
 0.7781512504 / 0.0222221045 =

You'll find the formula here: http://www.1728.org/compint2.htm
And a compound interest calculator here: http://www.1728.org/compint.htm
(You'll find both are helpful for this problem).
