Answer:
C. 72 million
Step-by-step explanation:
Put the appropriate value of x into the correct formula and do the arithmetic.
... For the year 2002, x = 2002 -1980 = 22.
Then the population estimate is ...
... h(22) = 51.42 +15.473·log(22)
... = 51.42 +15.473·1.3424
... = 51.42 +20.77
... = 72.19 ≈ 72 . . . . million . . . . . matches choice C.

Answer:
Tara's current expression finds how much the school will be keeping. 50 x 2/5 (also written as 50 x 0.4) totals out as 20. $20 is 2/5 of $50. The expression that Tara SHOULD have written to find how much goes to the candle company would be 50 x 3/5 (also written as 50 x 0.6), as this adds up to 30. $30 is 3/5 of $50.
Step-by-step explanation:
50/5 = 10 which means that 1/5 of 50 = 10.
2/5 of 50 ($20) is kept by the school. This is what Tara's expression finds. This means that $30 is sent to the candle company, and can be found with the expression 50 x 3/5.
The decimals are created by dividing the numerator of the fraction by the denominator (I find it easier to do math with decimals).
Answer:
5k+9
Step-by-step explanation:
Since it's a square, all four sides are equal so divide the equation of the total by 4.
20k/4=5k
36/4=9
