PLEASE HELP (WILL NAME BRAINLYEST)

Mathematics
1 answer:
ira [324]3 years ago
7 0

Answer:

4.04 x 10^0 people/km^2 (x 10^0 is fairly redundant but if the answer is required in standard form then include it)

Step-by-step explanation:

Population Density = Population/Area

= 3.11 x 10^7 / 7.69 x 10^6

= 31,100,000 / 7,690,000

= 3110 / 769

= 4.04

= 4.04 x 10^0

Haley had 56 dollars she spent 5/8 of her money on a new shirt how much money did she have left after buying the shirt
Mrac [35]

First you would multiply $56 by 5/8:

56 * 5/8 = 35

Now you know that she spent $35 on the shirt. So, subtract 35 from 56 and that's your answer.

56 - 35 = 21

Haley has $21 after buying the shirt. :)
