Simplify to give:

Answer: because the 7 in 0.77 is in the tens place, while 0.077 has a 0 in the tens place, and 7 is greater than 0.
Answer:
It'll take approximately 34 years from today.
Step-by-step explanation:
in order to solve this problem we first need to find the rate of change, "k", to do that we will use the given information where the population was 1400 five years ago and its now 1000. Applying this data to the equation gives us:

We now know the value for "k", we can estimate how many years it will take for the bird population to dip below 100. We have:

It'll take approximately 34 years from today.
Answer:127

Step-by-step explanation:
multiply 4 times 6, divide by two to get the area of the front side, then multiply that by two to get eh area of the two triangles.
Then multiply each side, two sides of 5 time 7 and one side of 6 times 7
