Answer:

124°

Step-by-step explanation:

cos X = (11²+7²-16²)/2(11)(7)

= (121+49-256)/154

= -86/154

= -0.5584

X = cos~¹ -0.5584 = 124°

The population of turtles is doubling every 3 months. If there are 400 turtles now, how many will there
QveST [7]

First we need to know how many months is 2 years. To answer that we multiply the number of months in a year by 2 and get 48 months.

Every 3 months the population of turtles doubles, but to get how many times the population doubles, you need to divide 48 months by 3 to get 16.

So population of 400 will get <u>doubled</u> 16 times in the following <u>two</u> years.

We construct the following equation where p is the final population,

p=400\cdot2\cdot16=\boxed{12800}

Hope this helps. :)

I need geometry help
fiasKO [112]
I believe you can do x + 2.7 = 16.

I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.

Your answer is 16 - 2.7
