Answer:

110 in. = 9  1/6 ft, or 9 ft 2 in

Step-by-step explanation:

Please try to do a better job of formatting your next question.  Thanks.

110 in       1 ft

-------- * --------- = 9 1/6 ft  or  9 ft 2 in

   1          12 in

110 in = 9 ft  2 in.

To convert 110 inches to feet and inches, we need to know the conversion factor that:

[tex]1\ foot = 12\ inches[/tex]

So, first, divide the total inches by 12 to get the number of feet:

[tex]\frac{110\ inches}{12\ inches/foot} = 9\ feet[/tex] with a remainder.

The remainder represents the inches that do not make up a full foot. The remainder can be calculated as follows:

[tex]110\ inches - (9\ feet \times 12\ inches/foot) = 110\ inches - 108\ inches = 2\ inches[/tex].

So, 110 inches is equal to 9 feet and 2 inches.

Therefore, 110 inches = 9 feet 2 inches.

Answer:

4x=6

Step-by-step explanation:

The value of the equation is 4x = 6.

The two equations in the system are added or subtracted to produce a new equation with just one variable when using the addition/subtraction method. The other variable must cancel out for the new equation to have just one variable.

Given

eq 1 :8x+3y=14

eq 2 :4x+3y=8

eq1 - eq 2

(8x+3y=14) - (4x+3y=8)

=> (8x-4x) + ( 3y-3y) = (14-8)

=> 4x + 0 = 6

4x = 6.

Examples of Quadratic Equation. A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable.

Final answer:

A real-life example of a quadratic model is a ball's trajectory when thrown upwards, described by the quadratic equation h(t) = -4.9t^2 + v0t + h0, with -4.9 representing the acceleration due to gravity.

Explanation:

A common example of a quadratic model in real life is the path of a projectile. For instance, when you throw a ball, its trajectory can be described by a quadratic equation. Let's say a person throws a ball upwards with an initial velocity, and we want to model the ball's height above the ground over time.

The quadratic equation for the ball's height h at time t can be written as: h(t) = -4.9t2 + v0t + h0, where -4.9 is the acceleration due to gravity (in meters per second squared), v0 is the initial velocity (in meters per second), and h0 is the initial height (in meters).

For example, if the initial velocity is 14.3 m/s and the ball is thrown from the ground (initial height is 0), the equation becomes h(t) = -4.9t2 + 14.3t. To find when the ball hits the ground, we solve for t when h(t) = 0 using the quadratic formula.

The balance in the account after 4 years, compounded continuously at 11%, is approximately $3884.25.

The formula for continuous compounding is given by [tex]\(A = Pe^{rt}\)[/tex], where:

- [tex]\(A\)[/tex] is the final amount,

- [tex]\(P\)[/tex] is the principal amount (initial investment),

- [tex]\(e\)[/tex] is the mathematical constant approximately equal to 2.71828,

- [tex]\(r\)[/tex] is the interest rate, and

- [tex]\(t\)[/tex] is the time in years.

In this scenario, [tex]\(P = $2500\)[/tex], [tex]\(r = 0.11\)[/tex] (11% expressed as a decimal), and [tex]\(t = 4\)[/tex] years. Plugging these values into the formula:

[tex]\[ A = 2500 \times e^{(0.11 \times 4)} \][/tex]

Calculate the exponent:

[tex]\[ A = 2500 \times e^{0.44} \][/tex]

Using the approximate value of [tex]\(e \approx 2.71828\):[/tex]

[tex]\[ A \approx 2500 \times 2.71828^{0.44} \][/tex]

[tex]\[ A \approx 2500 \times 1.5537 \][/tex]

[tex]\[ A \approx 3884.25 \][/tex]

Therefore, the balance in the account after 4 years, with an initial investment of $2500 at a continuously compounded interest rate of 11%, is approximately $3884.25.

If $2500 is invested at a rate of 11% compounded continuously, find the balance in the account after 4 years. Use the formula A=Pe^(rt)

Answer:  [tex]Range:[/tex]{[tex]1,3,4,7[/tex]}

Step-by-step explanation:

We know that, by definition, the Domain is the set of all the x-coordinates of the ordered pairs  and the Range is the set of all the y-coordinates of the ordered pairs.

Therefore, given [tex]f=(2,3),(5,7),(5,4),(9,1)[/tex], you can observe that the set of all second elements of ordered pairs (the values of "y") is the following:

{[tex]3,7,4,1[/tex]}

 Therefore, we can conclude that if [tex]f=(2,3),(5,7),(5,4),(9,1)[/tex] , then the range is:

 [tex]Range:[/tex]{[tex]1,3,4,7[/tex]}

Answer:

The range of f is {1 , 3 , 4 , 7}

Step-by-step explanation:

* Lets revise the relation

- f is a relation between x and y

- x is the input of the relation

- y is the output of the relation

- x is called the domain of the relation

- y is called the range of the relation

- The range is the corresponding value to x

* Now lets solve the problem

∵ f = {(2 , 3) , (5 , 7) , (5 , 4) , (9 , 1)

∵ x = {2 , 5 , 9}

∴ The domain of f is {2 , 5 , 9}

∵ y = {1 , 3 , 4 , 7}

∴ The range of f is {1 , 3 , 4 , 7}

Answer:

The factors are: (3a+2b +ab-6)(3a+2b -ab+6)

Step-by-step explanation:

[tex](a^2-4)(9-b^2)+24ab[/tex]

We need to solve the above expression using factorization.

Multiplying (a^2-4)(9-b^2)

9(a^2-4)-b^2(a^2-4) + 24ab

9a^2 -36 -a^2b^2+4b^2 + 24ab

Rearranging:

9a^2 + 4b^2 +24ab -36 -a^2b^2

We try to make perfect square of the form a^2+2ab-b^2

We have 24ab that can be written as 12ab + 12ab

Now, we can arrange the above equation:

9a^2 +12ab+ 4b^2 -(a^2b^2-12ab +36)

(3a)^2 +2(3a)(2b) + (2b)^2 -((ab)^2 -2(ab)(6)+(6)^2)

The perfect square will be:

(3a+2b)^2 - (ab-6)^2

Now We know a^2 - b^2 = (a+b)(a-b)

Here a = 3a+2b , b=ab-6

So,

(3a+2b +(ab-6))(3a+2b - (ab-6))

(3a+2b +ab-6)(3a+2b -ab+6)

So, the factors are: (3a+2b +ab-6)(3a+2b -ab+6)

Final answer:

Diego's method may introduce bias by not representing all student subgroups, suggesting that a random, stratified random, or systematic sampling method would better reflect student satisfaction with cafeteria food.

Explanation:

The question asks if selecting the first 25 students who purchase a lunch at the cafeteria is a good way for Diego to sample students to determine satisfaction with the cafeteria food. This sampling method may lead to bias because it does not represent all subgroups within the school population equally. For instance, it may only capture the opinions of students who already have a preference for cafeteria food, thus overlooking those who avoid it due to dissatisfaction. A better approach would be a random sampling method, where every student has an equal chance of being selected, ensuring a more accurate reflection of the entire student body’s opinion.

To improve the survey, Diego could consider using a stratified random sample, where the school population is divided into strata, such as grade levels or lunch periods, and then a random sample is taken from each stratum. This approach helps ensure that all segments of the student population are represented. Alternatively, a systematic sampling method, where every nth person is selected from a list or a line, could provide a more structured yet still random selection process compared to Diego's original plan.

Diego's approach is convenient but prone to bias. Random sampling across various days would improve representativeness and accuracy.

Diego's approach to surveying the students about cafeteria satisfaction has both strengths and weaknesses. Let's break down the pros and cons step by step:

1. **Convenience**: Approaching students during lunchtime in the cafeteria is convenient because it allows Diego to access a large number of students in one place and at a time when they are likely to be available.

2. **Sampling Bias**: However, selecting only the first 25 students who purchase lunch on a Monday might introduce sampling bias. For example, if there is a rush in the cafeteria during that time, Diego might end up surveying students who are in a hurry and may not accurately represent the entire student population.

3. **Limited Sample Size**: The sample size of 25 students is relatively small. While a larger sample size is not always necessary for accurate results, a larger sample size generally leads to more reliable findings. With only 25 students surveyed, there's a risk of the results being skewed by chance variations.

4. **Day of the Week Bias**: Monday might not be the best day to conduct the survey. Students' satisfaction with cafeteria food might vary depending on the day of the week due to factors like menu rotation or weekend leftovers. Therefore, surveying only on Mondays might not provide a comprehensive picture of overall satisfaction.

5. **Response Bias**: There's also the potential for response bias. Students who are particularly satisfied or dissatisfied with the food might be more likely to respond to Diego's survey, leading to results that don't accurately reflect the general sentiment of all students.

6. **Alternatives**: A better approach might be to conduct the survey at different times and days of the week to capture a more diverse range of student experiences. Additionally, Diego could use random sampling techniques to ensure that every student has an equal chance of being surveyed, reducing the risk of bias.

In summary, while Diego's approach is convenient, it may not yield the most accurate or representative results due to potential sampling bias, limited sample size, and other factors. To improve the validity of the survey findings, Diego should consider adjusting his sampling method and survey timing.

Formula for Area of cubic prism= 6a^2

where a is length of a side

Area=6(12)^2

        =6(144)

         =864 !

Answer:

B

Step-by-step explanation:

volume = length x width x height

For the top half i use the formula for the area of a triangle (area = base x height ÷ 2), which results in 45. times it 10 and you have 450³ which is the volume of the top part.

For the bottom half it is just 10 x 10 x 10 = 1000³

450³+1000³=1450³

The Volume of the frozen figure is C. 1,000 cm³.

To calculate the volume of the frozen figure, we need to determine the shape of the mold first. Assuming the mold is a rectangular prism, we can use the volume formula for a rectangular prism:

Volume = length × width × height

Given that the dimensions of the mold are:

Now, let's calculate the volume:

Volume = 10 cm × 9 cm × 10 cm = 900 cubic centimeters (cm³)

The correct answer to the question C. 1,000 cm³

Answer:

Width = [tex]1\frac{1}{3}[/tex] ft

Step-by-step explanation:

The tank holds 150 gallons of water.

7.5 gallons holds 1 ft³ of water.

So 150 gallons will hold;

[tex]\frac{150}{7.5}[/tex] × 1 ft³ = 20 ft³

The volume of the tank = Length(l) × Width(w) × Height(h) = 20 ft³

i.e 5 ft × w × 3 ft = 20 ft³

15w ft² = 20 ft³

w = [tex]\frac{20 ft^3}{15 ft^2}[/tex] =  [tex]1\frac{1}{3}[/tex] ft

Let's start with y = 4x + b (since 4 is the slope);

We need to find what number should be put instead of b;

Then, let's see what needs to be done;

Plug in the y and x values from the coordinate (22,12) into y=4x+b;

12 = 4(22) + b

Solve;

12 = 88 + b

12 - 88 = b

b = -76

Remember the equation y = 4x + b? Put the -76 instead of b:

y = 4x + -76

or: y = 4x - 76

That is the equation.

To make it standard form, put x and y both in the left side, with x first then y:

-4x + y = -76

^^Answer!

Final answer:

The equation of the line which passes through the point (22, 12) with a slope of 4, when written in standard form, is -4x + y = -76.

Explanation:

To write the equation of a line that includes the point (22, 12) and has a slope of 4 in standard form, we begin with the point-slope form of a line equation, which is y - y1 = m(x - x1). Substituting the given point and slope values, we have y - 12 = 4(x - 22).

Next, we simplify and convert this equation to standard form Ax + By = C. Standard form requires that x and y terms are on the left side and the constant is on the right:

y - 12 = 4x - 88
Add 12 to both sides:
y = 4x - 76
Subtract 4x from both sides:
-4x + y = -76

This is now in standard form and matches one of the given choices.

Answer: There are 21 eggs left.

Step-by-step explanation:

One carton has 12 eggs.

2 cartons are two times one carton, so two cartons have 2 times 12 eggs.

2 * 12 = 24

There are 24 eggs in two cartons.

Margot uses 3 eggs. We subtract 3 eggs from 24 eggs.

24 - 3 = 21

Answer: There are 21 eggs left.

There are 21 eggs are left if each carton 12 eggs. There are 2 full cartons in the refrigerator. Margot uses 3 eggs to make a quiche.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

Each carton contains = 12 eggs

Number of carton = 2

Number of total eggs = 12×2 = 24

Margot uses 3 eggs to make a quiche.

Remaining eggs = 24 - 3 = 21

Thus, there are 21 eggs are left if each carton 12 eggs. There are 2 full cartons in the refrigerator. Margot uses 3 eggs to make a quiche.
