A plane climbs from an altitude of 6000 ft to a cruising altitude of 39,000 ft. The plane ascends at a rate of 6600 ft/min. How long will it take to reach cruising altitude?
The time taken to ascend from the initial height to the final height; Time taken = 5 minutes
What is the time taken?We are given;
Initial Height = 6000 ft
Final height = 6600 ft/min
Speed = 6600 ft/min
Now, the time taken to ascend from the initial height to the final height;
Time taken = (39000 - 6000)/6600
Time taken = 5 minutes

A variable in mathematics is a sign and placeholder for any mathematical object (from the Latin variabilis, "changeable"). A variable can specifically represent a number, a vector, a matrix, a function, its argument, a set, or one of its elements.
A variety of issues are resolved by algebraic calculations that treat variables like explicit integers in a single computation. The quadratic formula, for instance, can be used to solve any quadratic equation by exchanging the variables in the quadratic formula for the numerical values of the coefficients in the equation.

Sixty-one percent of employees make judgements about their co-workers based on the cleanliness of their desk. You randomly select 8 employees and ask them if they judge co-workers based on this criterion. The random variable is the number of employees who judge their co-workers by cleanliness. Which outcomes of this binomial distribution would be considered unusual?
The unusual outcomes for the binomial distribution are given as follows:
0 or 1 employee making judgements.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
In the binomial distribution, a measure is considered unusual if it is more than 2.5 standard deviations from the mean.
For this problem, the parameters are given as follows:
n = 8, p = 0.61.
Hence the mean and the standard deviation are given by:
E(X) = np = 8 x 0.61 = 4.88.[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{8(0.61)(0.39)} = 1.38[/tex]The bounds of usual outcomes are:

2^2x+1 + 2^x+2 = 12-2^x
Therefore the value of x is 2.
Given 2²ˣ ⁺ ¹ + 2ˣ ⁺ ² = 12 * 2ˣ
2²ˣ ⁺ ¹ + 2ˣ ⁺ ² = 12 * 2ˣ
We can write this as follows
aˣ ⁺ ⁿ = aˣ * aⁿ
2²ˣ * 2 + 2ˣ * 2² = 12 * 2ˣ
2ˣ * 2ˣ * 2 + 2ˣ * 2² = 12 * 2ˣ
By taking common terms aside we get
2ˣ * 2 (2ˣ + 2) = 12 * 2ˣ
By canceling the like terms we get
2ˣ + 2 = 6
2ˣ = 6 - 2
2ˣ = 4
2ˣ = 2²
∴ x = 2

The slope of a line, also known as the gradient is defined as the value of the steepness or the direction of a line in a coordinate plane. Slope can be calculated using different methods, given the equation of a line or the coordinates of points lying on the straight line.
given that, since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel.

Answer:
M2 slope = 90°
Step-by-step explanation:
The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on the straight line, slope can be determined using a variety of approaches.
Given that parallel lines must have the same angle from the horizontal and that slope is a measurement of that angle, parallel lines must therefore have the same slope, therefore lines with the same slope are parallel.
We can then deduce that if m1=90°, m2 must also be 90°.

Scientific notationScientific notation is a quick way to represent a number using powers of base ten.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Sum in scientific notationYou want to add the following two numbers in scientific notation:
2.53×10¹⁹3.197×10¹⁷When the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is 19.
Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 3.197×10¹⁷= 0.03197×10¹⁹
Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:
2.53×10¹⁹ + 0.03197×10¹⁹= (2.53 + 0.03197)×10¹⁹= 2.56197×10¹⁹
Finally, the result of the sum is 2.56197×10¹⁹.

You're going on a 1211-mile trip, and your car gets about 29 miles per gallon. Gas prices along your route average $3.10. Estimate the cost of gasoline for this trip by rounding the distance to 1200 miles, the mileage to 30 miles per gallon, and the cost of gas to $3.00 per gallon. Calculate the answer without using estimation and compare the two results. (Round your answers to the nearest cent.)
Using proportions, it is found that:
Without estimation, the cost is of $129.46.With estimation, the cost is of $120.For the estimation, the mileage was rounded up while the cost was rounded down, hence the estimated cost is less than the actual cost.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.
Without the estimate, the number of gallons used is:
1211/29 = 41.76 gallons.
Hence the cost is:
41.76 x 3.10 = $129.46.
With the estimate, the number of gallons used is:
1200/30 = 40 gallons.
Hence the cost is:
40 x 3 = $120.
For the estimation, the mileage was rounded up while the cost was rounded down, hence the estimated cost is less than the actual cost.

If a naval submarine was operating 310 feet below the surface of the ocean. To pass above an underwater mountain, or seamount, it rose 165 feet then 145 is the position of the submarine relative to the surface of the ocean now.
What is Equation?
Two expressions with an equal sign is called as Equation.
If a naval submarine was operating 310 feet below the surface of the ocean. To pass above an underwater mountain, or seamount, it rose 165 feet. we need to find the position of the submarine relative to the surface of the ocean now.
The submarine initial position=310 feet.
To pass above an underwater mountain, or seamount, it rose =165 feet.
The position of submarine is
