Saving all the money in a safe at home most likely means D. being thrifty

What is money?

Money is any commodity or verifiable record that is widely accepted in a given country or socioeconomic environment as payment for products and services and repayment of debts, such as taxes.

Money enables us to meet our most basic requirements, such as purchasing food and shelter and paying for healthcare. Meeting these demands is critical, and if we don't have enough money to do so, our personal well-being and the community's overall well-being suffer considerably.

In this case, saving the money means that the person is careful with spending and doesn't want to waste the money. This implies thrifty.

We can replace x=20000 in the function so:

[tex]c(20000)=15000+8(20000)-\frac{20000^2^{}}{20000}[/tex]

and we simplify:

[tex]c(20000)=15500[/tex]

now h=1 is the cost of one more item so we evaluate for 20001

[tex]\begin{gathered} c(20001)=15000+8(20001)-\frac{20001^2}{20000} \\ c(20001)=195010 \end{gathered}[/tex]

Step-by-step explanation:

10 mm = 1 cm

1 mm = 1/10 cm

9. In 1621, the remaining settlers from the Mayflower and Native Americans gathered for a
harvest feast. There were 140 people at the feast and 40 more Native Americans than settlers.
How many people were from each group?

Answers

In order to solve this, we have to formulate some equations describing the number of people. The total number of people can be calculated by adding the number of natives to the number of settlers, like this:

Total = N + S

Where N is the number of natives and S is the number of settlers. We already know that there were 140 people in total, then we can rewrite the above expression to get:

140 = N + S

We are also told that there were 40 more native Americans than settlers, then the number of natives can be calculated by adding 40 to the number of settlers like this:

N = S + 40

By replacing S + 40 for N into 140 = N + S, we get:

140 = N + S

140 = (S + 40) + S

140 = S + 40 + S

140 = S + S + 40

140 = 2S + 40

140 - 40 = 2S + 40 - 40

100 = 2S

100/2 = 2S/2

50 = S

S = 50

By replacing 50 for S into N = S + 40, we get:

N = S + 40

N = 50 + 40 = 90

N = 90

Then, there were a total of 90 natives and 50 settlers

From the origin of the coordinate plane, how many units does one travel along the y-axis to find the point with the coordinates (1,8)?

Answers

Solution:

Let's recall that in a coordinate plane, we consider (0, 0) as the origin because this is the point where the x and y-axes intersect.

Therefore, the unit you travel along the y-axis from the origin is:

8 - 0 = 8 (Value of y given - Value of y at the origin)

The ratio 25 : 15 as a fraction in the simplest form can be written as 5/3.

What is ratio?

The quantitative relation between two amounts showing the number of times one value contains or is contained within the other. Ratio are represented in the following way -  a : b, c : d etc

Given is 25 to 15.

We can express this ratio as a fraction in the simplest form as -

25 : 15 = 25/15

Now, we have to ensure that only whole numbers are their in the numerator and denominator. So in simplest form, we can write -

25 : 15 = 25/15 = (5 x 5)/(5 x 3) = 5/3

Simplest form in fraction will be 5/3

Therefore, the ratio 25 : 15 as a fraction in the simplest form can be written as 5/3.

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 65%pure antifreeze. The company wants to obtain 260 gallons of a mixture that contains 45% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be

Answers

Answer:

80 gallons of water

180 gallons of premium antifreeze solution.

Explanation:

Let's call X the number of gallons of water and Y the number of gallons of the premium antifreeze solution.

The company wants to obtain 260 gallons of the mixture, so our first equation is:

X + Y = 260

Additionally, the mixture should contain 45% of pure antifreeze and the premium antifreeze solution contains 65% pure antifreeze. So, our second equation is:

0.45(X + Y) = 0.65Y

Now, we need to solve the equations for X and Y. So, we can solve the second equation for X as:

[tex]\begin{gathered} 0.45(X+Y)=0.65Y \\ 0.45X+0.45Y=0.65Y \\ 0.45X=0.65Y-0.45Y \\ 0.45X=0.2Y \\ X=\frac{0.2Y}{0.45} \\ X=\frac{4}{9}Y \end{gathered}[/tex]

Then, we can replace X by 4/9Y on the first equation and solve for Y as:

[tex]\begin{gathered} \frac{4}{9}Y+Y=260 \\ \frac{13Y}{9}=260 \\ 13Y=260\cdot9 \\ 13Y=2340 \\ Y=\frac{2340}{13} \\ Y=180 \end{gathered}[/tex]

Finally, replacing Y by 180, we get that X is equal to:

[tex]\begin{gathered} X=\frac{4}{9}Y \\ X=\frac{4}{9}\cdot180 \\ X=80 \end{gathered}[/tex]

Therefore, the solution should have 80 gallons of water and 180 gallons of premium antifreeze solution.

Ex) The function f(x) is shown on the graph. Plot two points on this grid to create the graph of the line that would represent f(x) - 2.

Answers

ANSWER and EXPLANATION

We have the graph of the function f(x) given.

We want to find 2 points that will represent f(x) - 2.

This (f(x) - 2) is a transformation of the function f(x).

It is called a vertical translation. It means that the function moves on the y axis.

It is generally represented as:

f(x) + b

Comparing the required translation with the general form, we can conclude that there is a -2 shift on the y axis.

Therefore, to find two points for the new function, we have to simply pick two points from the given graph and subtract 2 from their y coordinates.

Let the two points be:

(0, 1) and (-4, 4)

Therefore, the two points will be:

(0, 1) => (0, 1 - 2) = (0, -1)

(-4, 4) => (-4, 4 - 2) = (-4, 2)

Plotting them:

The green line is the line of the new function.

Write the sentence as an equation. 136 is equal to 194 times b Type a slash (/) if you want to use a division sign.

Answers

Given the sentence 136 is equal to 194 times b, we are to write this statement as an equation.

Let us take it one after the other.

For 194 times b, this can be written as;

= 194b .

Since 136 is equal to the exxpression, the final equation will be gotten by simply equationf 136 to 194b as shown;

136 = 194b

194b = 136

Solution:

The formula to get the volume of the rectangular pyramid is:
