A scanner scanned 72 photos in 8 minutes. If it scans photos at a constant rate, it can scan (BLANK) photos in 23 minutes. pls fill in blank

8x2 is 16. 23-16 is 7. 72 is the answer of 8x9 so 7x9 is 63. 63+576 is 639

so in 23 minuets the scanner can scan 639 photos

Step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
