A water cooler has a storage capacity of 50 litres . If each student on an average consumes 750ml of water. Then how many times cooler tank has to be filled to quench the thirst of 1200 student of school
The water cooler tank has to be filled 18 times to quench the thirst of 1200 students.
We have
Number of students= 1200
Water consumption per student= 750 ml
So, Total water consumption
= Number of students × Water consumption per student
= 1200 × 750 ml
= 900000 ml
= 900 Liter
Now, the time cooler tank has to be filled to quench the thirst
= 900 / 50
= 18 times
Thus, the water cooler tank has to be filled 18 times to quench the thirst of 1200 students.

The x and y intercepts for the linear equation x – 2y = -8 is
Answer:
x- intercept = - 8 , y- intercept = 4
Step-by-step explanation:
to find the x- intercept let y = 0 in the equation and solve for x
x - 2(0) = - 8
x - 0 = - 8
x = - 8 ← y- intercept
to find the y- intercept let x = 0 in the equation and solve for y
0 - 2y = - 8
- 2y = - 8 ( divide both sides by - 2 )
y = 4 ← y- intercept
Vehicles generally decrease in value around 14% per year. If you buy a vehicle priced at $39,500 , this can be modeled by the equation A=39500(0.86)t . Estimate the value of the vehicle after 4 years. Round to the nearest cent and do not round until the final calculation.
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..
To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.
Substituting t = 4 into the equation:
A = 39500(0.86)^4
A ≈ 39500(0.5996)
A ≈ 23726.20
Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.
This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

Comment on division of fractions
Fractions can be divided several ways. Two ways that are commonly taught are "invert and multiply", or "match denominators". Here, we have used the second of these methods.
If we were to "invert and multiply", the computation would be ...
(33/8)(4/11) = (33/11)(4/8) = 3(1/2) = 3/2
Instead, we multiplied 11/4 by 2/2 to make it be 22/8, so having a denominator of 8 matching that of the numerator. Then the value of the compound fraction is the ratio of the numerators:
(33/8)/(22/8) = 33/22 = (3/2)(11/11) = 3/2
which must be true in order for the relationship zyx~wvu to be correct
In order for the relationship zyx ~ wvu to be correct, the following conditions must be true:
Corresponding angles are congruent: The angles formed by matching vertices should have the same measures in both triangles. This ensures that the corresponding angles are equivalent.
Corresponding sides are proportional: The lengths of the sides that connect the corresponding vertices of the triangles should have a consistent ratio. This implies that the corresponding sides are proportional to each other.
These conditions are based on the definition of similarity between two triangles. If both the corresponding angles are congruent and the corresponding sides are proportional, then the triangles zyx and wvu are considered similar (denoted by ~).
Therefore, in order for zyx ~ wvu to be correct, the congruence of corresponding angles and the proportionality of corresponding sides must hold true.

theater gives away one free ticket to every 10th customer and two free
tickets to every 25th customer. The manager wants to give away four free
tickets when the customer is both a 10th and a 25th customer.
If 120 customers have bought tickets today, how many free tickets has the manager given away?
Using proportions, it is found that the manager has given away 22 tickets.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, we have to find the proportion between the number of customers and 120 and the ones that receive the prize, as follows:
120/10 = 12 receive at least one free ticket.120/25 = 4..., hence 4 receive at least two free ticket.The customers who are both a 10th and a 25th customer are the 50th and the 100th customers, hence:
12 - 2 = 10 customers receive one free ticket(the ones who are the 10th, except the 50th and 100th).4 - 2 = 2 customers receive two free tickets.2 customers receive four free tickets.Hence the number of tickets given away is:
10 + 2 x 2 + 2 x 4 = 22.
The manager has given away 22 tickets.

Peyton is going to invest $440 and leave it in an account for 5 years. Assuming the
interest is compounded annually, what interest rate, to the nearest tenth of a percent,
would be required in order for Peyton to end up with $520?
Answer:
The required interest rate would be of 3.4% a year.
Step-by-step explanation:
The amount of money earned in compound interest, after t years, is given by:
\(P(t) = P(0)(1+r)^t\)
In which P(0) is the initial investment and r is the interest rate, as a decimal.
Peyton is going to invest $440 and leave it in an account for 5 years.
This means that \(P(0) = 440, t = 5\)
So
\(P(t) = P(0)(1+r)^t\)
\(P(t) = 440(1+r)^5\)
What interest rate, to the nearest tenth of a percent, would be required in order for Peyton to end up with $520?
This is r for which P(t) = 520. So
\(P(t) = 440(1+r)^5\)
\((1+r)^5 = \frac{520}{440}\)
\(\sqrt[5]{(1+r)^5} = \sqrt[5]{\frac{52}{44}}\)
\(1 + r = (\frac{52}{44})^{\frac{1}{5}}\)
\(1 + r = 1.034\)
Then
\(r = 1.034 - 1 = 0.034\)
The required interest rate would be of 3.4% a year.
The following show a change of scale made by an architect in one of his drawings. Old: 1 inch = 16 meters. New: 1 inch = 2 meters. Which is the change in scale factor from the old scale to the new scale?
1 to 8
2 to 8
8 to 1
8 to 2
The change in scale factor from the old scale (1 inch = 16 meters) to the new scale (1 inch = 2 meters) is 1 to 8.
The change in scale factor is the ratio of the new scale to the old scale. In this case, the old scale is 1 inch = 16 meters and the new scale is 1 inch = 2 meters. To find the ratio, we divide the new scale by the old scale, which gives us:
new scale / old scale = 2 meters / 16 meters = 1/8
Therefore, the change in scale factor from the old scale to the new scale is 1 to 8. This means that one unit of measurement on the new scale (1 inch) represents 8 times less than one unit of measurement on the old scale (16 meters). In other words, the new scale is 8 times smaller than the old scale.
A change in scale factor is a way of comparing two different scales by calculating the ratio of the two scales. It is often used in fields such as architecture, engineering, and cartography to create scaled-down or scaled-up versions of objects, plans, or maps. In this case, the architect changed the scale from 1 inch = 16 meters to 1 inch = 2 meters. This means that for every inch on the new drawing, there are 8 inches on the old drawing. This change in scale factor helps to maintain proportion and accuracy in the drawings, as well as to make them easier to read and understand.
