Answer:

14 × 10^(-19) m

Step-by-step explanation:

We are told that the diameter of the red blood cell is 7 × 10^(-6) m

And that number of red blood cells in the person is; 2 × 10^(-13) red blood cells

Since they are held end to end, the length of the line would be;

7 × 10^(-6) × 2 × 10^(-13) = 14 × 10^(-19) m

180 product of a prime factor using indices
zvonat [6]
Start with 180. 
<span>Is 180 divisible by 2? Yes, so write "2" as one of the prime factors, and then work with the quotient, 90. </span>

<span>Is 90 divisible by 2? Yes, so write "2" (again) as another prime factor, then work with the quotient, 45. </span>

<span>Is 45 divisible by 2? No, so try a bigger divisor. </span>
<span>Is 45 divisible by 3? Yes, so write "3" as a prime factor, then work with the quotient, 15 </span>

<span>Is 15 divisible by 3? [Note: no need to revert to "2", because we've already divided out all the 2's] Yes, so write "3" (again) as a prime factor, then work with the quotient, 5. </span>

<span>Is 5 divisible by 3? No, so try a bigger divisor. </span>
Is 5 divisible by 4? No, so try a bigger divisor (actually, we know it can't be divisible by 4 becase it's not divisible by 2)
<span>Is 5 divisible by 5? Yes, so write "5" as a prime factor, then work with the quotient, 1 </span>

<span>Once you end up with a quotient of "1" you're done. </span>

<span>In this case, you should have written down, "2 * 2 * 3 * 3 * 5"</span>

Nikitich [7]

Answer:

Step-by-step explanation:

the answer is

$194 (start) / <u>100 (100%)</u> = $1.94 (1%)

$1.94 * 7 = $13.58 (7%)

$13.58 * <u>13 (13 years)</u> <em>= $176.54 </em>

$194 (start) + <u>$176.54 (interest)</u> <em>= $370.54</em>
