Answer:

Fast train speed: 69 km/h

Slow train speed: 39 km/h

Step-by-step explanation:

Fast train:

-Time: 4.33

-Speed: x

-Distance: 4.33x

Slow train:

-Time:  7.66

-Speed: x - 30

-Distance: 7.66(x - 30)

7.66(x - 30) = 4.33x

7.66x - 229.8 = 4.33x

3.33x = 229.8

x = 69

A piece of toast came out of the toaster very overcooked.
Nikitich [7]

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

In triangle XYZ, the length of side XY is 23 mm and the length of side YZ is 36 mm. Which of the following could be the length o
svlad2 [7]
Answer: The correct answer is Choice D, 43 mm.

When you know 2 sides of a triangle, you can find the range for the final side of the triangle. 

First, if we subtract 36 - 23 = 13, the third leg must be more than 13. Otherwise, the two smaller legs would not meet to make the third leg.

Second, if we add 36 + 23 = 59, the third leg must be less than 59. Otherwise, the third leg would reach further than the other two legs could reach.

43 is the only number larger than 13 but smaller than 59 in our list.

diamong [38]
The inverse of p\implies q is \neg p\implies\neg q. (This eliminates B and D)

p\implies q translates to "if p, then q". This means the answer must be A.
