Answer:

There are many ideals that appear in American literature such as, but not limited to, all people are equal, The United States of America is the Land of Opportunity, independence is valued, The American Dream is attainable, and everyone can succeed with hard work and determination.

Answer:

Step-by-step explanation:

The line that best fits is

[tex]y=-0.03x+3.45[/tex]

Where [tex]x[/tex] is days and [tex]y[/tex] is time in minutes. So, we have [tex]x=15[/tex], replacing this in the equation and solving for [tex]y[/tex], we have

[tex]y=-0.03(15)+3.45=-0.45+3.45=3[/tex]

Therefore, on the 15th day his best time for the day is 3 minutes.

Answer:

The value of [tex]x[/tex] :

[tex]x = 16[/tex]

Step-by-step explanation:

-To find the value of x, you need to use [tex]3x + 18[/tex]  and [tex]66\textdegree[/tex] written as in equation like this:

[tex]3x + 18 = 66[/tex]

-Then, you solve for it:

[tex]3x + 18 = 66[/tex]

[tex]3x + 18 -18 = 66 -18[/tex]

[tex]3x = 48[/tex]

[tex]\frac{3x}{3} = \frac{48}{3}[/tex]

[tex]x = 16[/tex]

So, therefore the final answer is [tex]x = 16[/tex].

Answer:

With that amount of butter she can make 26 pies.

For each pie she spends $1.13625 of butter.

Step-by-step explanation:

We first need to convert the total amount of butter she has from pounds to cups, to do that we need to multiply by 2, since for each pound she has 2 cups of butter, therefore:

butter in cups = 10*2 = 20 cups

Since each pie requires 3/4 cups of butter in order to calculate the number of pies she can make we need to divide the total amount of butter she has by the amount required for each pie. We have:

number of pies = total butter in cups / butter for one pie

number of pies = 20 / (3/4) = 20*(4/3) = 80/3 = 26.667

Since she can't make 0.66 pies, we will need to take only the integer part in consideration, therefore she can make 26 pies.

In order to know the cost for each pie we first need to know the cost for each pound of butter, to calculate that we take the total amount paid by her and divide it by the amount of butter she got.

price of butter per pound = 30.3/10 = 3.03

So each pound of butter costs $3.03 and is equivalent to 2 cups, we can make a rule of three to find the cost for each pie as shown below:

2 cups -> $3.03

3/4 cups -> $x

2/(3/4) = 3.03/x

2*(4/3) = 3.03/x

8/3 = 3.03/x

8x = 9.09

x = 9.09/8 = $1.13625

For each pie she spends $1.13625 of butter.

Answer:

y= -1/4x+3

Step-by-step explanation:

Answer:

f(x) = -2x + 8, x < 2

g(x) = 2x, x 》2

Step-by-step explanation:

|x - 2| is:

x - 2, for x 》2

-x + 2, for x < 2

For x < 2,

f(x) = 2(-x + 2) + 4

f(x) = -2x + 8

For x 》2,

g(x) = 2(x - 2) + 4

g(x) = 2x

The two linear functions for the given mode function y = 2|x - 2| + 4 will be y = -2x + 8 and y = 2x.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

As per the given mode function,

y = 2|x - 2| + 4

For x < 2 , |x - 2| = -(x - 2)

y = -2(x - 2) + 4

y = -2x + 4 + 4

y = -2x + 8

For x > 2, |x - 2| = x - 2

y = 2(x - 2) + 4

y = 2x - 4 + 4

y = 2x

Hence "The two linear functions for the given mode function y = 2|x - 2| + 4 will be y = -2x + 8 and y = 2x".

Answer:

B, 5x - 3 = 12

Step-by-step explanation:

3 less means subtracting, it's going to be -3.

It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.

3 less means your subtracting from something, which would make it 5x - 3.

Finally, they state that it equals 12, making the equation 5x - 3 = 12.

2(2x+7)-7(x+1)=28

4x+14-7x-7=28

4x-7x=28+7-14

x=-7

Answer:

Step-by-step explanation:

the volume of a rectangle is length x width x height, so the volume of the first rectangle is 2700.

the square has a length and width of 15 with a missing height. because they have the same volume, you can plug in the length and width of the square with the volume of the prism to find the height

v = length x width x height

2700 = (15)(15)h

2700/225 = h

the height is 12

Answer:

Step-by-step explanation:

- 1.4 < h + 1.1

      Solve for H. Get H by itself by subtracting 1.1 on both sides of the equation.

-1.4 - 1.1 = - 2.5

-2.5 < h

Answer:

There are no tables, but... I made a quick graph.

Step-by-step explanation:

y=2x-1 means that you start at (0,-1), one down from the origin (0,0). From there, you go up 2 and right one (1, 2), as well as down 2 and left 1 (-1, -2), since the slope is 2 (or [tex]\frac{2}{1\\}[/tex]). The lines continues in both directions, of course.

The table for the equation is y = 2x - 1

x y

0 -1

1 1

2 3

To determine which table represents the equation y = 2x - 1, we substitute the values of x into the equation and check if the resulting y values match those given in the table.

Substitute the values 0, 1, and 2 into the equation y = 2x - 1 and calculate the corresponding y-values:

For x = 0:

y = 2(0) - 1

y = 0 - 1

y = -1

For x = 1:

y = 2(1) - 1

y = 2 - 1

y = 1

For x = 2:

y = 2(2) - 1

y = 4 - 1

y = 3

The corresponding y-values for x = 0, 1, and 2 are -1, 1, and 3, respectively.

Answer:

a.  x = 61 degrees.

Step-by-step explanation:

By the External angle of a Triangle Theorem:

116 = 55 + x

x = 116 - 55

x = 61 degrees.

Answer:

a) 61

Step-by-step explanation:

The classic way to do this is to subtract 116 from 180, then adding that result to 55 and subtracting this second result from 180.

But another way that I have discovered is to subtract 55 from 116. You will get the same answer of 61.

Answer:

After three days Heng will have 9000.15 in his account.

Step-by-step explanation:

In order to solve this problem, we must apply the correct formula, which is given below:

[tex]M = C*(1 + r/n)^{n*t}[/tex]

Where M is the final amount, C is the money invested, r is the annual interest rate, n is the number of times the money gets compounded in a year and t is the time elapsed. Since in this account the money is compounded daily, it means that for each year it gets compounded 365 times, therefore n = 365.  The ammount will be compounded for 3 days, therefore we must convert this value to years in order to apply it in the "t" variable, we do that by dividing it by 365. With this knowledge we can solve the problem as shown below:

[tex]M = 9000*(1 + \frac{0.002}{365})^{365*\frac{3}{365}[/tex]

[tex]M = 9000*(1.000005479)^{3}\\M = 9000.15\\[/tex]

After three days Heng will have 9000.15 in his account.

Answer: 1/4 full.

Step-by-step explanation:

The question is asking for how much gas will be left in the tank after 2/3 of the gas in the tank is used.

There is currently 3/4 of the tank remaining.

To find 2/3 of 3/4, you can multiply the fractions together.

Do this by multiplying both numerators and both denominators:

[tex]\frac{2}{3} *\frac{3}{4} = \frac{2*3}{3*4} = \frac{6}{12}[/tex]

Then, subtract 6/12 from 3/4. You can do this by simplifying the first fraction to 2/4 (divide both the numerator and denominator by 3).

3/4 - 2/4 = 1/4

There will be 1/4 of the tank left.

Answer:

1/4

Step-by-step explanation:

We have 3/4 of a tank

We will use 2/3 of the  gas in the tank

See the diagram  That will leave us 1/4

Mathmatically

3/4*2/3 = 2/4 =1/2  this is the amount that is used

Subtract this from the amount in the tank

3/4 -1/2

3/4 -2/4 = 1/4

This is the amount that is left in the tank
