372.82 miles can the train go in an hour.
What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement.
For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
Speed = 600 Kmph
We know 1 Km= 0.62137119 miles
Now, converting Km to miles
speed = 600 x 0.62137119
= 372.82 miles
Hence, the speed is 372.82 miles.

The equation of the line of Kaya’s line in slope-intercept form is y = 15x + 25.
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given this, Kaya babysits to add money to her savings. She draws a graph to show how much she can earn by babysitting.
To calculate the equation of the line we at least need Two points on the line.
Two points on the graph (0, 25) and (5, 100) and also the y-intercept of the given line is 25(where x is 0)
From the general formula of the slope-intercept form of an equation:
y=mx+b,
where m is the slope
b is the y-intercept,
Since. m = (y - y')/ (x -x')
In our case m = (100 - 25)/5-0)
m = 75 /5
m = 15
and b = 25
Thus, the equation of a line:
y = 15x + 25
Therefore, The equation of the line of Kaya’s line in slope-intercept form is y = 15x + 25.

The limit of the infinite series diverges and the limit goes off to infinity
What is convergent and divergent series?If a series is convergent then it has bounded partial sums. Equivalently, if a series fails to have bounded partial sums then it is divergent.
When the series' limits reach its finite range of values, the series is said to be convergent. It is important that, partial sum of series, there should be a limit existed and that is finite in nature then only series converges
An infinite series is one that doesn't converge at any point , had a series of incomplete sums that went on forever and had no end. A series diverges when each sum does not approach zero.

Nilsa borrows $2,000 for 90 days at 18% exact interest.
On solving the provided question, we can say that so, the Interest Rate to be paid will be as = 5.08%
what is interest ?Simple interest is calculated by dividing the principal by the interest rate, the passage of time, and other elements. The formula used in marketing is simple return = principal + interest + hours. Using this approach, interest may be calculated most easily. The most common way to calculate interest is as a percentage of the principal balance. If he borrows $100 from a friend and agrees to pay it back with 5% interest, for instance, he will only pay his proportion of the 100% interest. $100 (0.05) = $5. You must pay interest when you borrow money and charge interest when you lend it. The majority of the time, interest is calculated as an annual percentage of the loan balance. This proportion is referred to as the loan's interest rate.
Interest Rate =($ Paid in Interest / $ Amount borrowed) X (360 / borrowed period)
= ($33 / $2600) X (360 /90)
=0.050769231

What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
A line has a slope of –9 and includes the points (–7,u) and (9,9).
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
-9 = (9 - u)/(9 + 7)
-9 = (9- u)/16

1a. In a class of 58 students, 35 offer Biology, 28 offer Economics and 15 offer Physics. Each
students offers at least one of the three subjects. If 12 students offer both Biology and
Economics, 7 students offer both Biology and Physics and 5 students offer both Economics and
Physics, how many students offer all three subjects?
b. A regular polygon with (2m+1) sides has each interior angle equal to 1440. Find the value of
m.
A. 9 students offer all three subjects.
B. The only possible value of m is 8.
Solution
A. We can use the Principle of Inclusion-Exclusion (PIE) to find the number of students who offer all three subjects.
Let's call the number of students who offer all three subjects "x".
The total number of students who offer Biology is 35, but we have to subtract the number of students who offer only Biology and Economics (12) and only Biology and Physics (7) to avoid counting them twice.
So, the number of students who offer Biology only is 35 - 12 - 7 + x = 16 + x.
Similarly, the number of students who offer Economics only is 28 - 12 - 5 + x = 11 + x.
And the number of students who offer Physics only is 15 - 7 - 5 + x = 3 + x.
The total number of students who offer at least one of the three subjects is 58, so:
16 + x + 11 + x + 3 + x = 58
30 + 3x = 58
3x = 28
x = 9
So, 9 students offer all three subjects.
B. In a regular polygon with (2m + 1) sides, each interior angle is equal to (2m + 1 - 2) * 180 / (2m + 1) = (2m - 1) * 180 / (2m + 1).
We know that this value is equal to 1440, so:
(2m - 1) * 180 / (2m + 1) = 1440
Expanding the right side:
2m - 1 = 1440 * (2m + 1) / 180
Dividing both sides by (2m + 1) and rearranging:
2m = 1440 * 2 / 180 + 1
2m = 16 + 1
m = 8.5
Since m must be a positive integer, the only possible value of m is 8.

The probability of rolling an even number is P = 0.5
How to find the probability?We know that the possible outcomes of a standard die are {1, 2, 3, 4, 5, 6}
The outcomes that are even are {2, 4, 6}
If all the outcomes have the same probability, then the probability of rolling an even number is equal to the quotient between the nmber of even outcomes (3) and the total number of outcomes (6).

Answer:
x = - 5/9
Step-by-step explanatiion:
8x-8+3(2x+2) = -4(x+3) is the original equation
Consider each term and simplify
3(2x+2) = 6x + 6
-4(x + 3) = -4x - 12

8x - 8 + 6x + 6 = -4x - 12
Move -4x to the left side; becomes + 4x
4x + 8x - 8 + 6x = -12

Answer: A: 3/10 of the school has blonde hair. B: there are 120 students
Step-by-step explanation: I might have done this wrong but anyway, I multiplied 2/5 by 1/4 and got 1/10, meaning 1/10 of the boys have blonde hair. I multiplied 3/5 (because 5/5 - 2/5 = 3/5) by 1/3 and got that 2/10 of the girls are blonde. I added these, and got that 3/10 of the school are blondes. That's A. Then, I set up the equation 3/10 = 36/x (x equals the total number of students in the school). When I solved it I got x = 120, meaning there are 120 students in the school.
