ASAP BRAINLIEST!!!!! 2. Dave leaves his office in Padelford Hall on his way to teach in Gould Hall. Below are several different

scenarios. Assume Dave’s path to Gould Hall is along a straight line which is 2400 feet long.
scenarios;

I. Dave leaves Padelford Hall and walks at a constant spend until he reaches Gould Hall 10 minutes later.

II. Dave leaves Padelford Hall and walks at a constant speed. It takes him 6 minutes to reach the halfway point. Then he gets confused and stops for 1 minute. He then continues on to Gould Hall at the same constant speed he had when he originally left Padelford Hall.

III. Dave leaves Padelford Hall and walks at a constant speed. It takes him 6 minutes to reach the half-way point. Then he gets confused and stops for 1 minute to figure out where he is. Dave then continues on to Gould Hall at twice the constant speed he had when he originally left Padelford Hall. On a sheet of paper, sketch a graph of these situation and use your graph to answer the following questions:

A. Compare and contrast the graph from before the 1-minute pause to the graph after the pause. What are the similarities and/or differences?

B. Using all three sketches, in which scenario does Dave reach Gould Hall fastest? How do you know?

C. Using all three scenarios, represent each scenario as an algebraic function.

GIVING BRAINLIEST TO CORRECT ANSWER What rotation about the origin is equivalent to R-200°
TiliK225 [7]

The rotation about the origin that is equivalent to R-200° is; C. R160

<h3>How to find the angle of rotation?</h3>

We are given;

Origin = -200°

Now, even if we add and also subtract a complete rotation of 360° (or even several rotations of 360°), we will want to have the similar rotation.

Thus;

By adding 360° to -200°, we have;

α = -200° + 360°

α = 160°

how many meters are equal to 5,253 centimeters? use how the placement of the decimal point changes when dividing by power of 10
motikmotik

Answer:

52.53\ \text{meters}

Step-by-step explanation:

1\ \text{meter}=100\ \text{centimeter}

1\ \text{centimeter}=\dfrac{1}{100}\ \text{meter}

In the question the quantity that is required to be converted to meters is 5253 centimeters.

5253\ \text{cm}=5253\times \dfrac{1}{100}\\ =52.53\ \text{meters}

So, the required measurement in meters is 52.53\ \text{meters}.

It would take Delia 3 hours longer to re tile their bathroom by herself than it would for kari to retile on her own. If they wor
max2010maxim [7]

Answer:

6hours

Step-by-step explanation:

From the given information:

Suppose it took Karl x hours to retile her bathroom,

Then it will take Della 3 hours longer i.e (3+x) hours

If Della and Karl work together or will take them 2 hours

The objective is to determine how long it will take Delia to retile the bathroom alone?

∴

\dfrac{1}{x}+\dfrac{1}{3+x}= \dfrac{1}{2}

\dfrac{x+3+x}{x(3+x)}= \dfrac{1}{2}

\dfrac{2x+3}{3x+x^2}= \dfrac{1}{2}

By cross multiplying, we have:

2(2x+3) = 3x+x²

4x + 6 = 3x + x²

3x + x² - 4x - 6

x² - x - 6 = 0

Using quadratic equation

x² -3x +2x - 6 = 0

x(x - 3) + 2(x - 3) = 0

(x +2) (x - 3) = 0

x + 2 = 0 or x - 3 = 0

x = -2 or x = 3

Since we are concerned about the positive integer,

Then, Karl = x = 3 hours while Della which is (3+x) = 3+3 = 6hours
