How you know the value <br>of the digits in the number 58

Anarel [89]

8 is in the ones place, so its value is equal to 8. The 5 is in the tens place, so the value is equal to 50. You can use this to help you:

Ones: Multiply the number in the ones place by one, and you'll get its value.

Tens: Multiply the number in the tens place by 10, and you'll get its value.

So on and so forth...

You work in the packaging department of a company that makes soup. The old soup can is 4 inches high and has a diameter of 3 inc

statuscvo [17]

Answer:

$h=6\ in$

Step-by-step explanation:

step 1

Find the volume of the old can

The volume of the can is equal to

$V=\pi r^{2} h$

we have

$r=3/2=1.5\ in$ ----> the radius is half the diameter

$h=4\ in$

substitute

$V=\pi (1.5)^{2}(4)$

$V=9\pi\ in^{3}$

step 2

Find the volume of the bigger can

Multiply the old volume by 1 1/2

$1\frac{1}{2}=1.5$

$V=(1.5)*9\pi\ in^{3}$

$V=13.5\pi\ in^{3}$

step 3

Find the height of the bigger can

we have

$V=13.5\pi\ in^{3}$

$r=1.5\ in$

substitute in the formula

$13.5\pi=\pi (1.5)^{2}(h)$

$h=13.5/(1.5)^{2}$

$h=6\ in$

nCr
you have n items and how many ways are there to chose r of them

nCr= $\frac{n!}{r!(n-r)!}$
remember than n! means n times all numbers before like
3!=3*2*1, 5!=5*4*3*2*1
9 stations, how many ways are there to chose 6 of them
9C6= $\frac{9!}{6!(9-6)!}$ =
$\frac{9!}{6!(3)!}$ =
$\frac{9*8*7}{3!}$ =
$\frac{9*8*7}{3*2*1}$ =
$\frac{3*4*7}{1}$ =
