on a recent scuba diving trip, kate and kara reached a depth of 130 feet. six and a half minutes later, after ascending at a con
vitfil [10]

Let x be the time and y is the depth

At x = 0 y = -130

At x= 6.5 y = 0

So the slope = (0- (-130) / ( 6.5 – 0) = 20

Y intercept b

0 = 20(6.5) + b

B= -130

The equation

Y = 20x -130

The domain all real numbers from 0 to 6.5

Range is all realnumber from -130 to 0

If Dante spins the spinner below 75 times, how many times should he expect it to land on "U"?​
Fed [463]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve making assumptions

Spinner = 10\ segments

U = 1

n=75

Required

Number of times to land on U

First, calculate the theoretical probability of U

Pr(U) = \frac{U}{Spinner}

Pr(U) = \frac{1}{10}

The expected number (E) of time to land on U is then calculated as:

E = Pr(U) * n

E = \frac{1}{10} * 75

E = 0.10 * 75

E = 7.5

Approximate

E = 8

<em>8 times</em>

<em></em>

<em>Follow the above steps, and you will arrive at your answer</em>

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
