10 x 10 = 100
20 + 20 + 20 + 20 +20 = 100
4 x 25 = 100
The total population in the region is 942000
<u>Step-by-step explanation:</u>
Radius of the region= 10 miles
Population density= 1500 per square mile
Area of the region = 2π(r x r)
= 2π(10 x 10)
=2(3.14) (100)
= 628 square miles
Population = 1500 x 628
= 942000
The total population in the region is 942000
Answer:
40 % of the snacks were carrot sticks.
Step-by-step explanation:
Total number of carrot sticks in lunch = 18
Total number of apple slices in lunch = 27
So, Total Snacks in the Lunch = Carrot Sticks + Apple Slices
= 18 + 27 = 45
Now,
=
⇒Percentage of Carrot Sticks = 40%
Hence, 40 % of the snacks were carrot sticks.
Answer:
add 21 to both sides to get everything on one side
x^2 - 10x + 21 = 0
do factorization, guess and check
(x - 7) (x -3) = 0
x =7, and x =3
Create a conversion factor from "<span>There are 6.02 × 10^23 atoms in 1 gram of hydrogen:"
6.02*10^23 atoms
-------------------------
1 gram
Then mult. 800 grams by this conversion factor:
</span>6.02*10^23 atoms 800 grams
------------------------- * ----------------
1 gram 1
This comes out to 4816*10^23 atoms, which, in scientific notation, is
4.816*10^26 atoms.
