how long is 90 minutes
90 minutes is about 5400 seconds long or 1.5 hours long.
What is time ?Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.
The minute is a measure of time that is typically equal to 60 seconds, or 1/60 of an hour. Because to leap seconds, a minute occasionally has 61 seconds in the UTC time zone. The minute is acceptable for use with SI units even though it is not a SI unit. Minutes are represented by the SI unit min.
Depending on the speed of the Earth's rotation, an hour is a measure of time that is traditionally calculated as 1/24 of a day and scientifically estimated to last between 3,599 and 3,601 seconds. There are 24 hours in a day and 60 minutes in an hour.
The second is the International System of Units' unit of time, previously defined as 1/86400 of a day. This element came from the split of a day into 24 hours, 60 minutes, and then 60 seconds each.
So , 90 minutes can be writen as
90 * 60 = 5400 seconds
90 minutes can also be written as

An insurance agent earns a base salary of $32,000, and a commission of 3% of his sales. He also receives an additional fee of $16. 00 for each home policy he sells. The agent has sold a total of $89,000 and 8 home policies this month. Find the commission and fees he has earned
To find the commission and fees the insurance agent has earned, we need to first calculate the 3% commission from the $89,000 in sales. This is equal to $2,670. Next, we need to calculate the additional fees from the 8 home policies sold. This is equal to $128. Thus, the total commission and fees the agent has earned this month is $2,798 ($2,670 + $128).
This commission and fees amount is in addition to the base salary of $32,000. Thus, the total earned this month by the insurance agent is $34,798 ($32,000 + $2,798).

The value of a 45 degree angle in an isosceles right angled triangle is: 1
In an isosceles right angled triangle, where AB = BC = x, the sides AB and BC form the hypotenuse, and the remaining side AC forms one of the legs.
For the 45 degree angle (let's call it angle A), the sine function can be used to find the ratio of the opposite side to the hypotenuse:
sin(A) = opposite side / hypotenuse = AC / AB = AC / xSince the triangle is isosceles, AC = AB = x, therefore:
sin(A) = x / x = 1So the sine of a 45 degree angle in an isosceles right angled triangle is 1.
Note: The cosine and tangent of 45 degrees can also be found using the other trigonometric ratios, but since only sine was requested, I only provided the sine value.

how many reams of paper are produced.
b. Find the inverse function and explain what it represents in this
problem.
The function C(x) that gives the total cost in a day as a function is C(x) = 0.03x + 1000
The inverse function is C^-1(x) = 100/3x - 100000/3
How to determine the total cost functionFrom the question, we have the following parameters that can be used in our computation:
Rate = $3 for every 100 reams
Initial cost = $1000
So, we have
C(x) = 3/100 * x + 1000
Evaluate
C(x) = 0.03x + 1000
The inverse functionTo do this, we make x the subject
So, we have
0.03x = C(x) - 1000
This gives
3/100 x = C(x) - 1000
So, we have
x = 100/3 C(x) - 100000/3

b. x = 5
c. x = 2
d. x = 7
By Using the Rational Zero Theorem, All of these are not the potential zeros of the polynomial y = 2x² + 5x - 24
What is Rational Zero Theorem?The Rational Zero Theorem states that if a polynomial has rational zeros, then the zeros must be the form p/q, where p is a factor of the constant term and q is a factor of the leading coefficient. In this case, the potential rational zeros are:
For example:- constant term = 24 and Leading coefficient = 2.
So, p/q = ±1, ±2, ±3, ±4, ±6, ±12, ±24
To determine which of these is not a zero, we can substitute each into the polynomial and check if the result is zero. For example, when we substitute x = 1 into the polynomial, we get:
y = 2x² + 5x - 24
At x = 1
y = 2(1)² + 5(1) - 24
y = 2 + 5 - 24
y = 19 ≠ 0

Check, on x = -2

The probability of 2 being the outcome when picking a random card is; P(2) = 40%
How to find the probability of selection?The outcomes of the results on the cards are either, 1, 2, 3 or 4 or more.
Now, the total possible outcome will be gotten by adding the frequencies of occurRence to get;
Total Outcome = 6 + 12 + 9 + 3
= 30
Now, the frequency of occurrence of 2 out of the total outcome is 12. Thus;
Probability of 2 being the outcome is;
P(2) = 12/30 = 0.4
Expressing in percentage gives 40%
