a group of teachers and students go on a school trip. for every teachers on the trip, there are four male students and five female students
if there are 30 female students on the trip, how many male students are there ?
Answers
The number of male students that went on the school trip given that there are 30 female students is 24
Calculating how many male students are there?Given that we have the following statement:
Every teacher is assigned 4 male students and 5 female students
The above statement means that we have the following ratio
Ratio = Male : Female
So, we have the following equation
Male : Female = 4 : 5
When the number of female students is 30, we have the following
Male : 30 = 4 : 5
Express as fraction
Male/30 = 4/5
So, we have
Male = 4/5 * 30
Evaluate
Male = 24
Hence, the number of male students is 24

Information concerning the buses is summarized in the table below. Bus 1, Bus 2, Bus 3, For the declining-balance method, the company uses the declining method rate. For units-of-activity method, total miles are expected to be 125,000. Actual miles of use in the first 3 years were 2021, 27,000; 2022, 35,000; and 2023, 33,000.
(a1) For Bus #3, calculate depreciation expense per mile under units-of-activity method.
Answers
Under the units-of-activity method, the depreciation expense per mile for Bus #3 is $0.4616.
How is the depreciation expense per mile determined?The units-of-activity method is one of the depreciation methods in use.
Under the units-of-activity method, the depreciation expense per unit is determined by dividing the depreciable amount by the total units of activity.
The depreciation amount (the value of the asset subject to depreciation) is the net of the total cost less the salvage value.
Depreciable amount of Bus #3 = $57,700 ($66,500 - $8,800)
Expected total miles for Bus #3 = 125,000
Depreciation expense per mile for Bus #3 = $0.4616 ($57,700 ÷ 125,000)

0 is an angle in a right-angled triangle. tan 0 = 23/52 What is the value of 0? Give your answer in degrees to 1 d.p.
Answers
The value of the angle θ is approximately 24.2 degrees to 1 decimal place.
In a right-angled triangle, the tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle. Given that tan θ = 23/52, we can find the value of the angle θ.
To find the value of θ, we can use the inverse tangent or arctan function. Taking the inverse tangent of both sides of the equation, we have:
θ = arctan(23/52)
Using a calculator or trigonometric tables, we can evaluate the inverse tangent of 23/52. The result is approximately 24.2 degrees.
Note that in the context of a right-angled triangle, the tangent function is defined for acute angles (less than 90 degrees). Since 0 degrees is the smallest possible angle, it is considered an acute angle in this case.

Answers
Answer:
The least three-digit number which leaves a remainder of 1 when divided by 5 or 6 is 101.
Step-by-step explanation:
This is because 101 is the smallest three-digit number which is not a multiple of either 5 or 6. To see that 101 is the smallest such number, you can check that 100 and 99 are both multiples of both 5 and 6, and 98 is a multiple of 6.

Cameron’s solution is unreasonable because 10 times 10 is 100, and 100 is not close to his product
Answers
Answer:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle, of length l and height h, is given by:
\(A = lh\)
The length of a rectangular wall is 16.5 feet. The height of the wall is 8.625 feet.
This means that \(l = 16.5, h = 8.625\)
Estimate of the area:
To use an "easy" multiplication, lets consider \(l = 17, h = 9\). So
\(A = lh = 17(9) = 153\)
Cameron determines the area of the wall to be 1423.125 square feet.
Very far from the area of 153, which means that he made a confusion with the decimal places. Thus, the correct answer is:
Cameron’s solution is unreasonable because 17 times 9 is 153, and 153 is not close to his product.

To determine which objects hold the same amount of liquid as a 96-fluid-ounce jug, we need to convert each of the given measurements to fluid ounces and then add them up. Here are the conversions:
Two 1-quart bottles = 64 fluid ounces (2 x 32)
Two 1-pint bottles = 32 fluid ounces (2 x 16)
One 1-quart bottle and eight 8-ounce fluid glasses = 96 fluid ounces (32 + 8 x 8)
So, the objects that hold the same amount of liquid as a 96-fluid-ounce jug are:
One 1-quart bottle and eight 8-ounce fluid glasses
Three 1-quart bottles
Therefore, the correct answer is:

For each dollar you raise the price, you lose 100 customers. How many dollars can you go up to maximize your profit, or should you go up at all?
Answers
Let:
P = Profit
n = Number of increments by $1
R = Revenue
The profit is given by:
\(\begin{gathered} P=10+1n \\ P=10+n \end{gathered}\)Therefore, the revenue is:
\(R=(10+n)(1000-100n)\)Expand the equation using the distributive property:
