Answer:

Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).

gogolik [260]

Answer:

4.99

Step-by-step explanation:

i cant remember how i got 4.99 but can show u how to check

= 55 +<u> 4.99 </u>= 59.99

59.99 divide <u>3</u> = 19.99666667

= 19.99666667 divide 4 (working in reverse as it says 4 times the orig no.)

Find the sum. Express your answer in simplest form. 4x+6/y^2-9 + 8x-7/y^2-9
Amanda [17]
It looks like you already have a common denominator (y^2-9). So, you can just add the two numerators and put that over the common denominator. Hope this helps!

In △ABC, m∠A=44°, m∠B=48°, and a=25. Find c to the nearest tenth.
Nookie1986 [14]

Answer:

=36.0

Step-by-step explanation:

We use the sine rule to find the missing sides as follows;

Lets find the missing angle C by using the summation of interior angles in a triangle.

C=180-(44+48)

=88°

Then,

a/Sin A=c/Sin C

25/Sin 44=c/Sin 88

c=(25 Sin 88)/Sin 44

c=35.97

The side c=36.0 to the nearest tenth.
