Use the rules for multiplication by powers of 10 to calculate 3 × 100
padilas [110]
3 × 100 = 300

the easiest way to do it is just add the same amount of zero's to the number you multiplied with. for example

3 × 10000 if you would just take out the zero's
it would look like this. 3 × 1

the answer of course would be 3 then you can put the zero's back in the answer (30000)

at least that's how I understood it

3 × 100 =

3 × 1(00) =
-->

-->
(00)
3 × 1(00) = 3

3 × 100 = 300

What two number that are the same have the product of 0.2 and the quotient of 0.8
Pie
Let the numbers be a and b, then ab=0.2 and a/b=0.8, so a=0.8b. Therefore, 0.8b^2=0.2 and b^2=0.2/0.8=2/8=1/4 and b=+1/2 or +0.5 and a=+0.8*0.5=+<span>0.4. The two numbers are therefore 0.5 and 0.4 or -0.5 and -0.4. The quotient is 0.4/0.5</span>

A rope is swinging In such a way that the length of the arc traced by a knot at its bottom end is
Sati [7]

Answer:

  13.6 ft

Step-by-step explanation:

The geometric sequence of arc lengths can be described by ...

  f(n) = a·b^n

We have (n, f(n)) = (3, 20) and (7, 12). Using these values, we can find the common ratio (b):

  20 = a·b^3

  12 = a·b^7

Then ...

  12/20 = (a·b^7)/(a·b^3) = b^4 = 3/5

We want the 6th term, which we can get from the 7th term by multiplying by b^-1.

  b^(-1) = (b^4)^(-1/4) = (3/5)^(-1/4) = √(√(5/3)) ≈ 1.13622

Then the 6th swing had an arc length of ...

  f(6) = f(7)·b^-1

  f(6) = (12 ft)(1.13622) ≈ 13.63 ft ≈ 13.6 ft
