Answers

Answer 1
Each dollar is equivalent to $1.50 Euros
Answer 2

The constant of proportionality Or the value of Euros is 3/2 times of the value of a dollar.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

To obtain the constant of proportionality we'll need to determine at least two coordinate points from the graph they are, (1, 3/2) and (2, 3).

Let, no. of dollars be 'x' and no. of euros be 'y'.

So, y = kx.

3/2 = k.

Another way is (3 - 3/2)/(2 - 1).

= (3/2)/1

= 3/2.

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?

Answers

Answer:

400 people

Step-by-step explanation:

15 = 12

500 = x

Cross multiply

15x = 12 × 500

Divide both sides by 15

[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex]  (* means multiplication if you do not know)

[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

Divide 500 by 15 that equals 33.33 then multiply that number by 12 and that equals 399.96 which is then rounded up to 400/500 people prefer eating out rather than cooking at home.

Answer: Q1: D. Distribute 3 through the parenthesis

Step-by-step explanation:

As for the second question, I am not sure how to begin. Sorry

Answer:

For the first question: 3(p - 3) = 2p + 7, the first step would be to distribute 3 to both terms in the parentheses

For the second question:

6n + 11 = -7 + 3n

-3n               -3n

3n + 11 = -7

      -11    -11

3n = -18

3n/3 = -18/3

n = -6

Check:

6(-6) + 11 = -7 + 3(-6)

-36 + 11 = -7 + -18

-25 = -25, since these match n definitely equals -6

A-Real, Rational, integer

B-Real, Rational

C-Irrational, Integer

D-Real, Irrational
Please Help Me ; ^;

Answers

Answer: Real, irrational

Step-by-step explanation:

Real because it is an actual measurement. Irrational because π can't be expressed as a fraction. Not an integer because integers are whole numbers.

The correct classification is -Real, Irrational

What is irrational number?

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.

Irrational numbers are real numbers that cannot be represented as a simple fraction. These cannot be expressed in the form of ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.

Given number: 7* pi

Here, 7 is the real number.

But pi is real but not rational number.

pi is an irrational number.

Hence, the correct classification of 7 pi is Real, Irrational.

Step-by-step explanation:

Subtract  2 x  from both sides of the equation.

y = 8 − 2 x

Substitute  8 − 2 x  for  y  into  x ^2 − y = 0  then solve for  x .

x = 2 , − 4

New Technology Leads to Bigger CitiesIn the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in GreatBritain, a fast development of society following the introduction of machines. The United States was slower than Great Britain tofully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for theirfamilies as well as to sell. The abundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry,More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United Statesalso settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildingsfor living and working. They needed ways to move around the city. We call this process urbanization.In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urbanareas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast andMidwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and wouldsoon reach one million residents.The urbanization of the United States quickened due to technology improvements. Without innovations in food production, thefactories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well.
