In a hotel a group of 240 children had food provision for 50days. After 10days ,40 children left the hotel. For how many days would the remaining food last
The food will therefore be plenty for 60 days. The assumption that the rate of food consumption will remain constant during the provision should be noted as it may not be totally accurate in real-world scenarios.
Mathematically, this can be expressed as:
240 x 50 = C x D
The result of simplifying the left side of the equation is:
12000 = C x D
40 kids left the motel after 10 days, leaving the following number of kids:
240 - 40 = 200
Now, we can calculate how many days the remaining food will endure for 200 kids using the same proportionality equation:
12000 = 200 x D
The result of multiplying both sides of the equation by 200 is:
D = 12000/200 = 60
The food will therefore be plenty for 60 days.
The assumption that the rate of food consumption will remain constant during the provision should be noted as it may not be totally accurate in real-world scenarios.

The instantaneous rate of change at x=1.
What is function?In mathematics, a function is a relation between sets that assigns to each element of a given set, exactly one element of a related set. This relationship between two sets is called a mapping, and it is commonly represented using a function notation. Functions are used to describe mathematical relationships and are studied extensively in mathematics, computer science, and other related fields.
The instantaneous rate of change at x=1 can be estimated using the concept of derivatives. A derivative is a mathematical operation that measures the rate at which a function changes with respect to its input. In this case, the derivative of the given function will measure the rate at which the function changes with respect to the input x=1.
The derivative of a function can be calculated using the formula:
f′(x)=limh→0[f(x+h)-f(x)]/h
Where f′(x) is the derivative of the function, f(x) is the function, and h is a small number close to zero.
To calculate the derivative of the function at x=1, we can plug in x=1 into the formula:
f′(1)=limh→0[f(1+h)-f(1)]/h
By calculating this limit, we can estimate the instantaneous rate of change at x=1.

A school guidance counselor is concerned that a greater proportion of high school students are working part-time jobs during the school year than a decade ago. A decade ago, 28% of high school students worked a part-time job during the school year. To investigate whether the proportion is greater today, a random sample of 80 high school students is selected. It is discovered that 37.5% of them work part-time jobs during the school year. The guidance counselor would like to know if the data provide convincing evidence that the true proportion of all high school students who work a part-time job during the school year is greater than 0.28. What are the appropriate hypotheses for this test?
H0: p = 0.28 versus Ha: p < 0.28, where p = the proportion of all high school students who work a part-time job during the school year.
H0: p = 0.28 versus Ha: p > 0.28, where p = the proportion of all high school students who work a part-time job during the school year.
H0: p = 0.28 versus Ha: p < 0.28, where p = the proportion of high school students in the sample who work a part-time job during the school year.
H0: p = 0.28 versus Ha: p > 0.28, where p = the proportion of high school students in the sample who work a part-time job during the school year.
answer B
Option D has the correct direction of the alternative hypothesis but uses the sample proportion in the null hypothesis.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
The appropriate hypotheses for this test are:
H0: p = 0.28 (the proportion of all high school students who work a part-time job during the school year is 0.28)
Ha: p > 0.28 (the proportion of all high school students who work a part-time job during the school year is greater than 0.28)
This is because the guidance counselor is interested in whether the proportion of all high school students who work part-time jobs during the school year is greater than 0.28, which was the proportion a decade ago. The null hypothesis states that the proportion is 0.28, and the alternative hypothesis states that it is greater than 0.28. Since the alternative hypothesis is one-sided (greater than), this is a one-tailed test.
Option B correctly states the null and alternative hypotheses with the appropriate population proportion in the null hypothesis and the direction of the alternative hypothesis. Options A and C use the sample proportion instead of the population proportion in the null hypothesis. Therefore, Option D has the correct direction of the alternative hypothesis but uses the sample proportion in the null hypothesis.

There are 5,500 milliliters in a bottle of laundry detergent. How many liters is this? 4. 5 liters 5. 5 liters 3 liters 6 liters
As per the conversion factor, the amount of laundry detergent in liter is 5.5 liters (option b).
When we want to convert units from one measurement system to another, we use something called a conversion factor. A conversion factor is a ratio that expresses the relationship between two different units of measurement. In this case, we want to convert milliliters (mL) to liters (L).
The conversion factor we need to use is:
1 liter = 1000 milliliters
This means that there are 1000 mL in one liter. We can use this conversion factor to convert 5,500 mL to liters.
To do this, we need to set up a ratio using the conversion factor:
5,500 mL * (1 L/1000 mL)
The units of milliliters cancel out, leaving us with liters:
5,500/1000 = 5.5 L
So the answer is 5.5 liters.

The final answer is: cos(α + β) = (3i - √190) / 10.
\( \alpha \) and \( \beta \) are first quadrant angles with \( \cos (\alpha)=\frac{\sqrt{5}}{10} \) and \( \sin (\beta)=\frac{\sqrt{10}}{10} \).

It would take the apprentice alone 11 hours to complete a kitchen island, the same amount of time it took the cabinet maker and apprentice together.
When the cabinet maker and apprentice work together, they are able to complete the kitchen island in 8 hours. This implies that the apprentice is able to do their portion of the work in 3 hours, while the cabinet maker does their portion in 8 hours. Therefore, if the apprentice were to work on the kitchen island alone, it would take them 11 hours to complete it, the same amount of time it took the cabinet maker and apprentice together. This is because the apprentice does not have the same level of experience and expertise as the cabinet maker, so they are not able to complete the same amount of work in the same amount of time as the cabinet maker.

A school is holding a carnival and hopes to raise $500. Child ticket cost $3 and adult tickets cost $5. If the school sells x child tickets and y adult tickets, then the equation 3x + 5y = 500 expresses the fact that the school raised exactly $500 from ticket sales.
1. Solve the equation for x.
2. Explain when it might be helpful to rewrite the equation this way.
Answer:
To solve the equation 3x + 5y = 500 for x, we need to isolate x on one side of the equation. First, we can subtract 5y from both sides to get 3x = 500 - 5y. Then, we can divide both sides by 3 to get x = (500 - 5y) / 3.
It might be helpful to rewrite the equation in terms of one variable if we want to solve for one unknown quantity in terms of another. In this case, rewriting the equation in terms of x allows us to see how many child tickets the school needs to sell to raise exactly $500, given any number of adult tickets sold. This can be useful in planning and budgeting for the carnival.

[tex]C(t) = C_0 * e^{(r\times t)}[/tex]
Here, C_0 is the initial cigarette consumption, r is the growth rate, and t is the time variable. This model assumes that cigarette consumption grows exponentially over time.
We can use this model to predict cigarette consumption at any given time t.
To find the year in which cigarette consumption reaches C_goal, we need to solve for t_goal in the equation above. That is, we need to find the value of t for which C(t) = C_goal. To do this, we can rearrange the equation above and solve for t:
[tex]t_{goal} = (1/r) \times ln(C_{goal}/C_0)[/tex]
Here, ln denotes the natural logarithm. This equation gives us the value of t for which cigarette consumption reaches the goal amount C_goal.

1/3(12x+6x-21) combine like terms
= 1/3(18x-21) distribute
= 6x - 7
What do I put (please do not put a complicated answer) and this is 7th grade math
Answer:
x = 17
Step-by-step explanation:
We Know
(6x + 3) + (7x - 44) = 180°
Let's solve
6x + 3 + 7x - 44 = 180
13x - 41 = 180
13x = 221
x = 17°
So, x = 17°
What is the equation of the line that is parallel to the line y = x 4 and passes through the point (6, 5)? y = x 3 y = x 7 y = 3x – 13 y = 3x 5
The equation of the line that is parallel to the line y = x 4 and passes through the point (6, 5) is y = x - 1
The line y = x + 4 has a slope of 1 because it is in the form y = mx + b, where m is the slope of the line. To find a line parallel to this line, we need to use the same slope of 1.
Now, we can use the point-slope form of a linear equation to find the equation of the line that passes through the point (6, 5) with a slope of 1:
y - y1 = m(x - x1)
where m = 1, x1 = 6, and y1 = 5.
Plugging in the values, we get:
y - 5 = 1(x - 6)
Simplifying, we get:
y - 5 = x - 6
y = x - 1

Lupe measured the height of three rectangular prisms she was using to pack up some clothing. The large box was 7/8 of a meter tall. The medium box was 2/6 shorter than the large box. The small box was 1/4 of a meter shorter than the medium box. If the boxes are all stacked on top of each other, what is their combined weight
If the boxes are all stacked on top of each other, what is their combined height is 11/8
Height of large box = 7/8m
Height of medium box = 2/6m shorter than large box
Height of small box = 1/4m shorter than the medium box
Calculating the height of the medium and small boxes.
Medium box height x large box height
= 2/6 × 7/8
= 7/24
Since, the small box is 1/4 of a meter shorter than the medium box, therefore its height -
= 7/24 - 1/4
= 5/24
Calculating the height of three boxes -
7/8 + 7/24 + 5/24
= 21/24 + 7/24 + 5/24
= 33/24
= 11/8

Charlotte borrows $9000 to buy a second-hand car.
The loan must be repaid over 5 years at 12% p.a. simple interest. Calculate the:
a total amount to be repaid b monthly repayment amount if the repayments
are spread equally over the 5 years
Answer:
a) To calculate the total amount to be repaid, we need to add the interest to the principal amount.
The formula for simple interest is:
I = P * r * t
where I is the interest, P is the principal amount, r is the interest rate per year, and t is the time in years.
In this case, P = $9000, r = 12% = 0.12, and t = 5 years.
So, the interest on the loan is:
I = $9000 * 0.12 * 5 = $5400
The total amount to be repaid is:
Total amount = Principal + Interest = $9000 + $5400 = $14400
Therefore, the total amount to be repaid is $14,400.
b) To calculate the monthly repayment amount, we need to divide the total amount to be repaid by the number of months in 5 years (60 months), since the repayments are spread equally over 5 years.
Monthly repayment amount = Total amount to be repaid / Number of months
= $14,400 / 60
= $240
Therefore, the monthly repayment amount if the repayments are spread equally over the 5 years is $240.
