Answer:

Option A. greater than

Step-by-step explanation:

The percent of seventh graders surveyed who preferred fiction = 0.75 or 75%

The percent of eight graders surveyed who preferred fiction = 0.68 or 68%

Now we can say the percentage of seventh graders who preferred fiction is GREATER THAN the percentage of eight graders who preferred fiction.

Therefore option A. is the correct option.

The equation would be y = -5/2x - 14. Since the slope and a coordinate pair was given, I used point slope form to figure out the equation.

Work:

y - 6 = -5/2 (x+8)
y - 6 = -5/2x - 20
  + 6               +6
______________

2(2/5) divided 2(-1/5)

we do PEMDAS meaning parenthesis first

2(2/5) = 4/5(calculator)

or

2/1x2/5=4/5

now

2/1x-1/5=-2/5

4/5/-2/5 we get -2

Answer:

  • 523 grams
  • 52 grams

Step-by-step explanation:

To find the initial amount, put 0 where t is in the formula and do the arithmetic.

  A(0) = 523(1/2)^0 = 523(1) = 523

The initial amount is 523 grams.

__

To find the amount remaining after 100 years, put 100 where t is in the formula and do the arithmetic.

  A(100) = 523(1/2)^(100/30) ≈ 523(0.0992123) ≈ 52

About 52 grams will remain after 100 years.
