1 m = 1 x 10⁶ μm
1 m² = (1 x 10⁶)² μm²
1 m² = 1 x 10¹² μm²

area = 1.5 / 1 x 10¹²  m²
Area = 1.5 x 10⁻¹² m²

14% of the town's population is over the age of 65. If there are 320 residents over the age of 65, approximately what is the tow
marshall27 [118]

Answer & Step-by-step explanation:

So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857, which is the answer. To double check, you'd just find 14% of 2285.7142857 (multiply by 0.14) which is equal to 320. Because you can't have fractions of people, however, you'd have to round the answer up to 2286 people.

If that is too difficult to understand them hope this is easier

14% of the towns population is 320. Let P denote the towns population.

14/100 * P =320

14P/100 = 320

14P = 32000

divide both sides by 14

P = 2285.71

the towns population is 2286

Hope this helps!

Answer:

2nd answer choice No, 6/2 does not equal 2/24 :)

Step-by-step explanation:

6/2=3 while 24/10=2.4

Another way you could think about it:

6*2=12

2+2=4

6*3=18

4+2=6

6*4=24

6+2=8

So 24 ounces of the shake would only be 8 grams of protein.
