How do you determine the number of zeros to annex in the product of 0.002 and 0.003?
Marat540 [252]
<span>0.002 x 0.003 = 0.000006

the zeroes are multiplied by the power of 10 which is 1/10 in particular.
For example.
The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that </span><span><span>
1. </span> N x 0.1 = N/0.1 < N</span> <span><span>
2. </span> 1 x 0.5 = 0.5 </span><span><span>
3. </span> 2 x 0.1 = 0.2</span> <span><span>
4. </span> 100 x 0.55 = 55</span><span>  </span>

<span>These three examples and stances then suggest the claim that the product is not equal to the whole number used in the equation.<span>

Which of the following is the correct factored form for the given equation? 2x^2+8x+6=0
3241004551 [841]
It would be 2(x+3)(x+1)=0

Explanation:
I used factor by grouping. You multiply the first term (2) by the last term (6). This gives you 12 then take the factors of 12 that add up to the middle term 8. You get 6 and 2.
It should look like 2x^2+6x+2x+6=0
when you do factor by grouping you factor the first two terms and then the last two terms separately. So you get (2x+2) and (x+3). (2x+2) could be factored into 2(x+1). Then you put everything together and get 2(x+3)(x+1)=0

If an airplane descends 15 feet every 1.45 seconds, how far would the airplane travel in three and a half minutes? The equation
NemiM [27]

\qquad\qquad\huge\underline{{\sf Answer}}

Here we go ~

The air plane descends 15 feels every 1.45 seconds, so it's unit rate is :

\qquad \sf  \dashrightarrow \:  \dfrac{15}{1.45} \:  \:  ft / sec

Now we have to calculate the descent in 3.5 minutes ~

\qquad \sf  \dashrightarrow \:  \dfrac{15}{1.45} \:  \:   \times 3.5 \times 60

\qquad \sf  \dashrightarrow \: 2172.41 \:  \: ft

So, the airplane descends 2172.41 feels in three and a half minutes ~
