Madelyn jokes 190.5 meters up a mountain . I’d she is 62 percent of the way up how tall is the mountain?

Answers

Answer 1
Answer:

The mountain is 307.26 meters tall.

Step-by-step explanation:

Given,

Distance jogged by Madelyn = 190.5 meters

This represents 62 percent of total height of mountain.

Let,

x be the height of mountain.

62% of x = 190.5

(62)/(100)*x=190.5\n0.62x=190.5

Dividing both sides by 0.62

(0.62x)/(0.62)=(190.5)/(0.62)\nx=307.258

Rounding off to 2 decimal places

x = 307.26 meters

The mountain is 307.26 meters tall.

Adele also must choose between leather or cloth seats for her vehicle. Leather seats come in three color choices; brown, black, and blue. Cloth seats come in two color choices; tan and gray. Using multiplication, Adele says she has (2)(3)(2), or a total of 12, choices for seat covers. Is she correct? Explain why or why not.

Answers

No,  she is not correct because she has 5 options of seat covers to choose from.

We have to determine the number of options for seat covers

Here given that,

Color options for leather seats =3

Color options for cloth seats = 2

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

What is the formula for combinations?

The total number of combinations = nCr!/n!(n-r)!

Where n is the total number of choices available, and r stands for the number of choices to be made.

Here  the number of leather seat options presented = 3

The number of options available for cloth seats =2

Total number of options = leather + cloth = 3 + 2 = 5

The number of options available to her

⇒ 5!/ 1!×(5-1)!

⇒ 5!/4!

⇒ 5×4!/4!

⇒ 5

She can only select one style of cover at a time, therefore she has five options for seat covers. The cover may be made of tan cloth, grey cloth, blue leather, black leather, or brown leather.

Hence,  she has 5 options of seat covers to choose from.

Answer:

Sample response: Adele is not correct. There are only 5 choices. Here, we are not able to use the fundamental counting principle because there are different choices for each material.

What are rational numbers and how do you tell the difference between integers? Please answer what are rational numbers first.

Answers

1. A rational number is a number that can be written as a fraction.

For example: 1/3, 5/7, 90/666, etc

Note: Any integer can be written as a fraction.

Look:

5 = 5/1 = rational

-14 = -14/1 = rational

2. There is no difference between a rational and integer.

Going to put your function in slope-intercept form for the sake of easier input into Desmos.

y - 2 = - (x + 5)
y - 2 = - x - 5
y = - x - 5 + 2
y = - x - 3
