Answer:
It is a chemical change ⇒ 1st answer
Step-by-step explanation:
* Lets explain the statements to solve the problem
- <u><em>A chemical change</em></u> occurs when a new substance is formed through
a chemical reaction
- Ex: cooking an egg
- <u><em>Change of reaction</em></u> is the rate of reaction it can be decreases or
increasing
- <u><em>A phase change</em></u> is a change from one state to another without a
change in chemical composition
- Ex: Condensation: the substance changes from a gas to a liquid
- <u><em>A physical change</em></u>, such as a state change or dissolving, but does
not create a new substance
- Ex: Breaking a glass
* Lets solve the problem
- A piece of toast came out of the toaster very overcooked.
∵ It is like the cooking an egg
∴ It is a chemical change
Answer:
1. the shape on the left had been enlarged with a scale factor 10 to give the shape on the right - all the lenghts are 10 times longer e.g AZ is 8, corresponding WZ is 80
2. corrseponding angles are equal
now, let's recall Cavalieri's Principle, "solids with equal altitudes and cross-sectional areas at each height, have the same volume".
so, even though this cylinder is slanted, it has the same cross-sectional area as a cylinder that's straight-up, whose altitude is h = 5, and radius r = 4.

Answer:
See below.
Step-by-step explanation:
This is conveniently done using a 24-hour representation of the given time:
... 2:30 pm = 14:30
Honolulu = 14:30 -10 = 4:30 . . . . 4:30 am
London = 14:30 - 0 = 14:30 . . . . 2:30 pm
Los Angeles = 14:30 -8 = 6:30 . . . . 6:30 am
Paris = 14:30 +1 = 15:30 . . . . 3:30 pm
Tokyo = 14:30 +9 = 23:30 . . . . 11:30 pm
Washington = 14:30 -5 = 9:30 . . . . 9:30 am
