Answer:
y = 1.705882353
Step-by-step explanation:Combine like terms: 20 + 9 = 29
29 + -10y + -7y = 0
Combine like terms: -10y + -7y = -17y
29 + -17y = 0
Solving
29 + -17y = 0
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-29' to each side of the equation.
29 + -29 + -17y = 0 + -29
Combine like terms: 29 + -29 = 0
0 + -17y = 0 + -29
-17y = 0 + -29
Combine like terms: 0 + -29 = -29
-17y = -29
Divide each side by '-17'.
y = 1.705882353
Simplifying
y = 1.705882353
C= πd+2l
C= π*62+2*100
C= 194.99+200
C= 394.99 m²
I don't know why it doesn't match up with the choices, but this is the correct answer. So when putting the answer in, put 394.68 since it's the closest answer chice
Answer:
The answer is 8
Step-by-step explanation:
Because 4x12 is 48 and so is 6x8
Ok because it only wants 3 significant digits your just take 103 and times it by the decimal form of 1.67% which is .0167 to get 1.720, now add that to 103 and multiply by .0167 again to get the populations after the second year(Use the population at that year to multiply by .0167). Do the same for the 3rd, 4th and 5th years and you should end with 112 million people.
The correct answer is 18 . if you follow pemdas it really helps.
