Most of the time we ____ energy but it is everywhere around us ​

Mathematics
1 answer:
pychu [463]3 years ago
3 0

Answer:

waste

Step-by-step explanation:

Try to think of something that doesn't involve energy and you won't get very far. Even thinking—even thinking about energy!—needs some energy to make it happen. In fact, everything that happens in the world uses energy of one kind or another. But what exactly is energy?

Energy is a bit of a mystery. Most of the time we can't see it, yet it is everywhere around us. Revving car engines burn energy, hot cups of coffee hold energy, street lights that shine at night are using energy, sleeping dogs are using energy too—absolutely everything you can think of is using energy in one way or another. Energy is a magical thing that makes other things happen. Everything in the world is either energy or matter ("stuff" around us) and even matter, when you really get down to it, is a kind of energy!

Irina-Kira [14]

Answer:

Step-by-step explanation:

for this graph  find rise over run ,  and where the line crosses they y axis.. sooo ..

it crosses at -2 and  the slope is rise over run  or y/x and I can see by the graph that the line goes up 1 when it goes over 1... so the slope is +1

sooo...

use the slope intercept form   y = mx + b

y = 1x + (-2)

y = x - 2   :)

wlad13 [49]

Answer:

5b=2f

Step-by-step explanation:

Priya uses 7\dfrac{1}{2} cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}

It means,

\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f

So, the relationship between b and f is "5b=2f".
