Step-by-step explanation:

To find irrational number between any two numbers, we first need to understand what a rational and irrational number is.

Rational number is any number that can be expressed in fraction of form [tex]p/q[/tex]. Since q can be 1, all numbers that terminate are rational numbers. Example: 1, 12.34, 123.66663

Irrational number on the other hand can't be expressed as a fraction and do not terminate. Also, there is no pattern in numbers i.e. there is no repetition in numbers after the decimal point.

For example: 3.44444..... can be expressed as rational number 3.45.

But 3.414114111.... is an irrational number as there no pattern observed. Also,it does not terminate.

We can find infinite number of irrational numbers in between two rational numbers.

Irrational numbers in between 0.3 and 0.7:

0.3101001000......

0.410100100010000....

0.51010010001.......

0.6101001000....

There are many others. We can choose any two as answers.

Step-by-step explanation:

The difference in elevations between a scuba diver at -8 meters and a shark at -29 meters is calculated as: -8 - (-29) = 21 meters.

The subject in question involves finding the difference in elevations. In this context, the scuba diver is swimming at an elevation of -8 meters, and the shark is at -29 meters. To find the difference, we subtract the lower number (-8) from the higher number (-29).

However, due to the negative signs, the difference will be calculated as follows: -8 - (-29) = -8 + 29 = 21 meters. Therefore, the difference in elevations between the shark and the scuba diver is 21 meters.

The sllope-intercept form:

[tex]y=mx+b[/tex]

[tex]6y-12=14x[/tex]          add 12 to both sides

[tex]6y=14x+12[/tex]      divide both sides by 6

[tex]y=\dfrac{14}{6}x+\dfrac{12}{6}\\\\\boxed{y=\dfrac{7}{3}x+2}[/tex]

To change the equation 14x=6Y-12 into slope-intercept form, first isolate Y by adding 12 to both sides, then dividing by 6. This results in the equation Y = (7/3)x + 2.

The equation provided is 14x=6Y-12 and we need to transform it to slope-intercept form, which has a general format of y = mx + b, where m is the slope and b represents the y-intercept.

Let's start by isolating y in the equation:

Answer:

enrollment decreases by 14.34%.

Step-by-step explanation:

Given that number of students enrolled in 2000 = 823

Given that number of students enrolled in 2010 = 705

705 is less than 823 so that means number of students enrollment is decreasing.

Decrease = 823-705 = 118

Percent decrease is given by formula:

[tex]Percent =\frac{part}{whole}\cdot100 =\frac{118}{823}\cdot100= 14.3377885784[/tex]

which is approx 14.34%.

A) -102 feet

She started at -38 feet. She then went -120 feet, so -38-120= -158. She then went +56 feet. -158+56=-102.

Answer:

The answer is A. -102

Step-by-step explanation:

If she started at 38 feet below sea level, we would describe it as -38. If she descended 120 feet deeper, than we subtract that from -38.

-38-120=-158

She is now 158 feet below sea level, or -158.

Then, if she climbs up 56 feet, we would add that to -158.

-158+56=-102

Answer:

1430 yards

Step-by-step explanation:

Note that [tex]1\text{ acre}=\dfrac{1}{640}\text{ square mile}.[/tex] Then

[tex]25\text{ acres}=\dfrac{25}{640}\text{ square mile}.[/tex]

If one side of the restangular field measures exactly [tex]\dfrac{1}{4}[/tex] mile, then let the second side be x miles and

[tex]\dfrac{25}{640}=\dfrac{1}{4}\cdot x,\\ \\x=\dfrac{\frac{25}{640}}{\frac{1}{4}}=\dfrac{25}{640}\cdot \dfrac{4}{1}=\dfrac{25}{160}=\dfrac{5}{32}\ mile.[/tex]

The perimeter of the rectangle will be

[tex]P=2\cdot \dfrac{1}{4}+2\cdot \dfrac{5}{32}=\dfrac{2\cdot 8+10}{32}=\dfrac{26}{32}=\dfrac{13}{16}\ mile.[/tex]

Since [tex]1\ mile=1760\ yards,[/tex] then [tex]\dfrac{13}{16}\ mile=\dfrac{13}{16}\cdot 1760=1430\ yards.[/tex]

To fence a 25-acre rectangular field with one side 1430 yards of fencing is needed.

To order fencing for a 25-acre, rectangular field, with one side measuring exactly  1/4 mile, we first need to determine the field's dimensions. Since a mile equals 1760 yards, one side of the field is

1/4 x 1760 = 440 yards.

Now, to find the other side, we use the area formula (Area = length x width).

The field is 25 acres, and 1 acre equals 4840 square yards. So the field has an area of 25 x 4840 square yards.

Let's denote the unknown side as 'width':

= 25 x 4840 = 440 x width

Width =  25 x 4840/ 440

= 275 yards

Now that we have both the length and the width, we can find the perimeter, which is the total length of fencing needed. The perimeter of a rectangle is 2  x (length + width).

Perimeter = 2 x (440 + 275) = 2 x 715

= 1430 yards

Therefore, to enclose the field completely, you would need 1430 yards of fencing.

Answer:

The APY of the saving account is 4.048656%

Step-by-step explanation:

We know the formula for APY which is given by

[tex]APY=(1+\frac{r}{n} )^n-1[/tex]

here, r= interset rate =  3.9886% = 0.039886

n = compounding cycles = 4

On plugging these values in the above formula, we get

[tex]APY=(1+\frac{ 0.039886}{4} )^4-1[/tex]

On simplifying this we get

APY = 0.04048656 =4.048656%

Answer:

APY = 4.0486561%

Step-by-step explanation:

Given is the Annual Percentage Rate (APR) = 3.9886% compounded quarterly.

Suppose Principal amount, P = $1.

time, t = 1 year.

interest rate, r = 3.9886% = 0.039886

period of compounding, n = 4 (for quarterly).

Future value = P * (1 + r/n)^(nt)

FV = 1 * (1 + 0.039886/4)^(1*4) = 1.040486561

Annual Percentage Growth = (FV/P)*100 = (1.040486561 / 1) * 100 = 4.0486561%

Hence, Annual Percentage Yield (APY) = 4.0486561%

Answer:

She would have to do 219 haircuts in a month for the costs to be the same, which would be $428.

Step-by-step explanation:

To find this we take the costs of the first place.

$438

Next we can look at the costs of the second place using x as the number of haircuts she'd do.

2x

Now we can set the two equal to each other to find the number of cuts.

438 = 2x

219 = x

Carrie would pay $438 and perform 219 haircuts each month.

To find out how much Carrie would pay and how many haircuts that would be, we need to set up an equation.

Let's assume the number of haircuts per month is x.

For self-employment at The Belmont Salon, Carrie would pay a fixed monthly rent of $438, so her total cost would be $438.

For the franchise option, Carrie would pay $2 for every haircut. So the total cost would be 2x.

Setting up the equation: 438 = 2x

To solve for x, we divide both sides of the equation by 2:

x = 438 / 2 = 219

Therefore, Carrie would pay $438 and perform 219 haircuts each month.

Solving the system using elimination reveals that the two equations are dependent, resulting in infinitely many solutions since they represent the same line. There is no unique solution for x and y.

To solve the system of equations 2x + 3y = 12 and -4x - 6y = -24 using the elimination method, we aim to eliminate one variable by combining the equations. First, notice that the second equation is exactly -2 times the first equation. If we multiply the first equation by 2, we would have identical left-hand sides but with opposite signs, which would cancel out when added together.

Multiplying the first equation by 2 gives 4x + 6y = 24. Now, add this new equation to the second equation:

Adding them results in 0 = 0, which indicates that the two equations are dependent, and the system has infinitely many solutions. This is because each equation is a multiple of the other, and they both represent the same line. Therefore, we cannot isolate x or y to find a unique solution. The system is consistent and dependent.

Answer:

1st blank is 0,14 dollars/1yuan, and 2nd blank is 1kg/2.2lb

Step-by-step explanation:

The tomatoes at the Chinese market would cost approximately $0.99 per pound, following the currency conversion rate from yuan to dollars and the weights conversion rate from kilograms to pounds.

To find the cost in dollars per pound from yuan per kilogram, we should use both the conversion rate from yuan to dollars and the conversion rate from kilograms to pounds. In this case, we are given that 1 yuan is worth 0.14 dollars and that 1 kilogram is approximately 2.20462 pounds. Therefore, the cost in yuans per pound would be 15.65 yuan/kg divided by 2.20462 lbs/kg, which equals approximately 7.09 yuan/pound. After converting it to dollars, it'd be approximately 7.09 yuan/pound times 0.14 dollars/yuan which gives us approximately $0.99 per pound.

2.) −$180/year

The average rate of change between Year 4 and Year 9 is -$180 per year.

A linear equation can be used to represent a non linear line. A linear equation is of the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the value of car after x years.

From the graph, at year 4, y = 2300, hence it is (4, 2300). At year 9, y = 1400, hence it is (9, 1400). Therefore:

[tex]Average\ rate\ of\ change=\frac{1400-2300}{9-4}= - 180[/tex]

Answer: There are 82.5% after school students who are enrolled in his classes.

Step-by-step explanation:

Let the total number of students be 100

Percentage of students who need help in computer science = 30%

So, number of students who need help in computer science = 30

Percentage of students who need help in maths = 70%

So, number of students who need assistance in maths  = 70

Of the students who need help,

40% are enrolled in Mr. Ellis's class during the school day,

So, it means 60% are enrolled in his class after the school day.

Number of students who are enrolled in his class after the school day = 60

Number of students who need help in Maths is given by

[tex]\frac{70}{100}\times 60=42[/tex]

Of the students that need help in maths, percent of students are enrolled in his class during the day = 25%

So, number of students who need help in maths and enrolled in his class after school hours

[tex]\frac{75}{100}\times 42=31.5[/tex]

Number of students who need help in computer science and enrolled in his class after school hours

[tex]\frac{30}{100}\times 60=18[/tex]

Therefore, there are [tex]31.5+18=49.5[/tex] students who joined his class after school hours,

Percentage of the after students who are enrolled in Mr. Ellis's classes is given by

[tex]\frac{49.5}{60}\times 100=82.5\%[/tex]

Hence, there are 82.5% after school students who are enrolled in his classes.

29.5% of the after-school students are enrolled in Mr. Ellis's classes.

1. Calculate the percentage of students who need help in computer science and are enrolled in his class:

  - 30% of the students need help in computer science.

  - 40% of those students are enrolled in his class during the school day.

[tex]\[ \text{Percentage of students needing help in computer science and enrolled in his class} = 30\% \times 40\% = 0.3 \times 0.4 = 0.12 = 12\% \][/tex]

2. Calculate the percentage of students who need help in math and are enrolled in his class:

  - 70% of the students need help in math.

  - 25% of those students are enrolled in his class during the school day.

[tex]\[ \text{Percentage of students needing help in math and enrolled in his class} = 70\% \times 25\% = 0.7 \times 0.25 = 0.175 = 17.5\% \][/tex]

3. Combine the two percentages to find the total percentage of after-school students enrolled in his classes:

  - 12% of the total students are those who need help in computer science and are in his class.

  - 17.5% of the total students are those who need help in math and are in his class.

Thus, the total percentage of after-school students enrolled in Mr. Ellis's classes is:

[tex]\[12\% + 17.5\% = 29.5\%\][/tex]
