Of the 25 fish that Karl caught
from the lake, 7 were trout. The
estimated population of the lake is
6,500 fish. About how many trout
would
you expect to be in the lake?

Answers

Answer 1

Answer:

1,820 trout

Step-by-step explanation:

Set up a proportion where x is the number of trout in the lake:

[tex]\frac{7}{25}[/tex] = [tex]\frac{x}{6,500}[/tex]

Cross multiply and solve for x:

25x = 45,500

x = 1820

So, you could expect 1,820 trout to be in the lake.

Answers

Answer:

120th customer will be the first one get all the three items.

Step-by-step explanation:

Given that:

Every 8th customer gets a free appetizer.

Every 12th customer gets a free beverage.

Every 15th customer gets a free fish of yogurt.

To find:

The first customer to receive all the three items.

Solution:

Here, we need to find nothing but the Least Common Multiple of the given three numbers 8, 12 and 15 to find the first person who will get all three free items.

Let us use factors of each number:

[tex]8 = 2\times 2\times 2\\12 = 2\times 2\times 3\\15 = 3\times 5[/tex]

The LCM will be:

[tex]2\times 2\times 2 \times 3 \times 5 = \bold{120}[/tex]

Therefore, the answer is:

120th customer will be the first one get all the three items.

A snowbank that is 6 inches deep is melting at a rate of 0.5 inch per hour. Write a linear function to model the scenario and identify the domain and range of the function.

Answers

Answer:

y = -0.5x + 6, Domain [0,12] and Range [0, 6]

Step-by-step explanation:

The slope in a linear function represents the rate of change. Since the amount of snow is decreasing (indicating a negative slope) at 0.5 inches an hour, our slope would be -0.5.

Our y intercept, 6, would be the starting amount of snow. At 0 hours, no snow has been melted.

Our domain is [0,12] these are the x values from where at zero there is 6 inches of snow and at 12 there is 0 inches of snow.

Finally, our range is [0,6]. Since there cannot be no more than 6 or less than 0 inches of snow, our range is [0,6]

Hope this helped!

If 4(r + 2) – 13 = 11, what is the value of r?

Answers

Answer:

r = 4

Step by step explanation :

Step 1 : Add 13 to both sides.

4(r + 2) - 13 + 13 = 11 + 13

4(r + 2) = 24

Step 2 : Divide by 4 on both sides.

[tex]\frac{4(r+2)}{4} = \frac{24}{4}[/tex]

r + 2 = 6

Step 3 : Subtract 2 from both sides.

r = 4

The value of r is 4 in the given expression and this can be determined by using the arithmetic operation.

Given :

Expression -  4(r + 2) – 13 = 11

The following steps can be used to evaluate the given expression:

Step 1 - Write the expression.

4(r + 2) – 13 = 11

Step 2 - Add 13 on both sides in the above equation.

4(r + 2) – 13 + 13 = 11 + 13

4(r + 2)  = 24

Step 3 - Multiply 4 by (r + 2) in the above expression.

4r + 8 = 24

Step 4 - Subtract 8 on both sides in the above expression.

4r + 8 - 8 = 24 - 8

4r = 16

Step 5 - Divide 4 on both sides in the above equation.

r = 4

The value of r is 4.

The difference between six, and a number divided by four is sixteen

Answers

Answer:

'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:

[tex]\frac{6\:-\:x}{4}=16[/tex]

Step-by-step explanation:

Let 'n' be the number

The difference between six and a number 'n' is written in an algebraic expression such as:

[tex]6 - x[/tex]

[tex]6-x[/tex] is obtained by 'subtracting, starting with 6'.

Dividing 6-x by 4 will become:

[tex]\frac{6\:-\:x}{4}[/tex]

so the sentence the difference between six, and a number divided by four is sixteen will become:

[tex]\frac{6\:-\:x}{4}=16[/tex]

Therefore, 'The difference between six, and a number divided by four is sixteen' will be translated into an equation such as:

[tex]\frac{6\:-\:x}{4}=16[/tex]

Read the following text critically and answer the questions given below. In its widest sense, government means the framework and rules by which decisions that affect a community as a whole are arrived at and carried out. In a narrower sense, however, government is a person or body of persons giving effect to the framework or rules. There are different forms of governments depending on the manner in which a government is run such as monarchies, military dictatorships, civilian dictatorships and democracies. Monarchs, military men and civilian dictators often wield unlimited power which might result into tyranny and despotism. A democratically elected government exercises power and authority granted by the constitution and traditions.A government is good, if it aims for the good of the people . The primary objectives for which such a government comes into existence are to maintain the rule of law look after its citizens without discrimination and fulfill their needs and work toward the establishment of welfare programs for the people. Only a government that has come into existence as an expression of the will of the people and adopts policies for the welfare of the people will have popular support. For this reason, a democratically elected government is certainly preferable to a benevolent dictatorship.In the real world there are three important qualities which citizens look for in their governments. The first is that the government should be representative; the second, that it should provide a reasonable degree of stability; and the third that it should look after the wellbeing of its citizens.The citizens of a country may sometimes demand policies that are short-sighted and disastrous in the long run. This is often seen in regard to economic policies. A good government is one that formulates and implements policies that are beneficial for the citizens and also ensure future prosperity of the country. That is to say, a good government should be expected to think for the future as well as act for the present requirements - about defense, economic development, education and employment.A good government should rise above the narrow views of the people and take measures, however unpopular and repugnant they may be when they are taken, to solve present problems and ensure a bright future. It must be prepared to accept constructive criticism and enter into a dialogue with dissident groups with a view to making its policies and measures acceptable. It always aims at the good of the people. The men and women forming such a government are persons who have the support of the people with them in good or bad times.To conclude, it may be said that a representative government i.e. a democratically elected government which is stable and which can act with circumspection and vision for the prosperity and welfare of its citizens as well as for the future of the nation as a whole is to be considered a good government. A good government should therefore take cognizance of what years ago Jean- Paul Rousseau wrote in his Du Contract Social about the ultimate source of authority of a good government. According to him, the government is only an agent of the people in whom vests the ultimate source of authority and for whom the government is functioning.1.What is the authors purpose for writing this article? 2.
