Answer:
Surface area:
Step-by-step explanation:
(Imagine there's line separating the rectangle and square)
<u>Rectangle</u>
l × w × h
3 cm × 13 cm × 3 cm
117 cm^3
<u>Square</u>
l × w × h
5 cm × 2 cm × 3 cm
30 cm^3
<u>Total Area</u>
117 cm^3 × 30 cm^3
3,510 cm^3

<span>In this case, use variables to represent the numbers, Fortunately, they are all in terms of the smaller number. So. let....
x = small number
(x+3) = middle number
2x = large number
If the sum is 75, then all of the numbers added together must equal this. So......
x + (x+3) + 2x = 75
4x + 3 = 75
4x = 72
x = 18
After we find x, we can conclude that..
Smaller number = 18
Middle number = 21
Large number = 36</span>
A - Yes it is fair because <span>he relative frequency of green is the highest.</span>
Answer: carbon cycle showes us the central importance of carbon in the biosphere.Carbon moves from one storage reservoir to another through a variety of mechanisms .biosphere is important because understanding how moves helps us to understand biological processes and factors that influence them.
Step-by-step explanation: Carbon cycles through ecosystems. cells use oxygen to break down sugar and obtain energy which is a process called respiration. Carbon is released and cycled back into the atmosphere as carbon dioxide.When living things die and decay the rest of the carbon that makes up living matter is released. Carbon will move from fossil fuels to the atmosphere when fuels are burned.
