The area of the wetland that will be covered in purple loosestrife 7 years from now is modeled by this expression.

500(1.2)^7

After evaluating the expression, the model predicts that approximately 1,792 acres of the wetland will be covered in purple loosestrife 7 years from now. This is not a valid prediction because the total area of the wetland is only 1,240 acres. So a constraint on the model is that the value of the expression 500(1.2)^t must be less than or equal to 1,240.

Step-by-step explanation:

Probability of getting heads

Outcome (head) = 1
Total outcomes = 2
P (head) = 1/2

Probability of getting an odd number

Outcome (odd) = {1, 3, 5} = 3
Total outcomes = 6
P (odd) = 3/6 = 1/2

The outcomes are equally likely because the probabiity of each outcome is the same.

The table shows the average weight of animals. How many more tons does a blue whale weigh than an African elephant? Explain how

AVprozaik [17]

Answer:

The African elephant weighs 111.5 tons less than a blue whale.

Step-by-step explanation:

Given:

Animal Weight(pounds)

African Elephant 15,000

Blue Whale 238,000

Now, to find the weight of how more tons does a blue whale weigh than an African elephant.

As given, 1 ton = 2,000 pounds.

So, to convert the weight from pound to tons by dividing:

African elephant $=15000\div 2000=7.5\ tons.$

Blue whale $=238000\div 2000=119\ tons.$

Now, to get the weight of how more tons is blue whale weigh than an African elephant we subtract:

$Blue\ whale - African\ elephant$

$=119 tons-7.5tons$

$=111.5\ tons$

Therefore, the African elephant weighs 111.5 tons less than a blue whale.

Answer both questions!

vodomira [7]

1) What is the equation for the line?
slope = 16/2 = 8

answer
equation
y = 8x

2) What is the equation of a line with a slope of 3 and a point (3, 1) on the line?

Express the equation in the form of y=mx+b where m is the slope and b is the y-intercept.

y - 1 = 3(x - 3)
y - 1 = 3x - 9
y = 3x - 8

answer
y = 3x - 8
