Answer:
Step-by-step explanation:
Volume of sphere = 4/3 *pi * r^3
= 4/3 * 3.14 * 52
= 523.33
There were 100 magazines altogether and she bought 50 of them.
All you have to do is start by multiplying 485 and 34 (485*34) to find how much he made by just weddings. That should be equal to 16,490. Then you have to multiply 18 by 87 because he charged 18 per copy and there was 87 copies so (18*87). This should now be equal to 1,566. Since you want the total you now should add them which should be 16,490+1,566 and that is equal to 18,056.
Answer:
First of all: Heat energy is transferred from higher to lower level.
Normally,a room temperature is about 25°C–27°C. Hot food has temperature higher than that, and (cold) drinks have temperature lower than that. So, heat is transferred from/to the atmosphere to maintain heat levels at the Normal temperature and pressure.
When kept in open, heat transfers from the food (higher level of heat) to atmosphere (lower level), decreasing it's temperature, i.e., making it cold.
Likewise, in case of (cold) drinks, heat is transferred to the drink (lower level of heat) from the atmosphere (higher level), hence making it warmer.
