The equation of the line q that is perpendicular to line p is  y = - 3 / 5 x - 9.

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, p has an equation of y = 5 / 3 x - 4 Line q includes the point (-10,-3) and is perpendicular to line p.  The equation of line q can be found as follows:

The product of the slope of perpendicular lines is equals to negative one.

Therefore, let's find the slope of line q.

m₁m₂ = -1

5 / 3m₂ = - 1

m₂ = - 3 / 5

Hence, the equation of line q is y = - 3 / 5x + b.

Let's find the y-intercept using (-10, -3)

-3 = - 3 / 5(-10) + b

-3 = 6 + b

-3  - 6 = b

b = -9

Therefore, the equation of line q is y = - 3 / 5 x - 9

Co-interior angles are the two angles that occur between two parallel lines intersected by a transversal.

The sum of the co-interior angles is 180 degrees.

(8x + 9)° and 51° are co-interior angles.

24 ounces of a 15% alcohol solution must be mixed with 16 ounces of a 20% alcohol solution to make a 17% alcohol solution.

Let x ounces of 15% alcohol must be mixed with the 16 ounces of 20% alcohol.

The amount of alcohol in 16 ounces solution is = (20/100) * 16 ounces

                                                                              = 3.2 ounces

The amount of alcohol in x ounces  solution is = (15/100) * x

                                                                              = 0.15x ounces

Total amount of alcohol is = (16 + x) ounces

According to the problem we get an equation,

(3.2 + 0.15x)/(16 + x) = 17/100

100(3.2 + 0.15x) = 17(16 + x)

320 + 15x = 272 + 17x

320 - 272 = 17x - 15x

48 = 2x

The surface area of a square pyramid is 192 cm²

What is the surface area of a square pyramid?

The term "surface" refers to the "outer or exterior part of an object or body." As a result, the total surface area of a square pyramid is the sum of its lateral face and base areas.

To find the surface area of the square pyramid, we'll use the mathematical formula.  

Mathematically, the formula for calculating the surface area A  of a square pyramid is :

S.A. = s² + sl

where,

s is the pyramid height,

l is the base length.

S.A. = (8)² + 8 * 16

S.A. = 64 + 128

S.A. = 192 cm²

In the scientific notation, the total population of Brazil and Lithuania is 2.02255 x 10⁸

Scientific notation

A method of expressing numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10 is known as Scientific notation.

Given,

In 2010, the population of Brazil was about 1.987 x 10⁸ people. The population of Lithuania was about 3.555 x 10⁶ people.

Here we need to find the total population of Brazil and Lithuania and expression the value in scientific terms.

Here we know that,

Population of Brazil = 1.987 x 10⁸

Population of Lithuania = 3.555 x 10⁶

In order to find the total population, first we have to make the exponent of the two value as equal,

For that we have to rewrite the population of Brazil as,

Population of Brazil = 198.7 x 10⁶

Now, we have to add the two population count in order to find the total population,

=> (198.7 x 10⁶) + (3.555 x 10⁶)

Take the exponent term as common,

=> (198.7 + 3.555) x 10⁶

=> 202.255 x 10⁶

Now, we have to move the two decimal point to simplify this one, then we get,

The probability that the mean battery life would be greater than 636.4 minutes if in a sample of 152 batteries having a variance of, 6724 and a mean life of 645 minutes is 0.0968.

The ratio of good outcomes to all possible outcomes of an event is known as probability. A lot of successful results for an experimental with 'n' results can be represented by the symbol x.

Given:

The variance = 6724,

The mean life of a battery, m = 645,

The total number of samples, n = 152

Calculate the probability of a mean battery life of lower than 636.4 minutes by the following formula,

z = m - x / (σ / √ n)

Here, x is the expected value, σ is the deviation, and z is the probability.

Substitute the values,

z = 645 - 636.4  / (82 / √ 152)         [σ = √ variance = √6724 = 82]

z = 1.29

Consult the cumulative standard normal table

P (z < 636.4) = 0.9032,

But we know that

P (z > 636.4) = 1 - P (z < 636.4)

P (z > 636.4) = 1 - 0.9032 = 0.0968

Therefore, the probability that the mean battery life would be greater than 636.4 minutes if in a sample of 152 batteries having a variance of, 6724 and a mean life of 645 minutes is 0.0968.

Law of cosines and Cosine Formula are other names for the cosine rule.

5 and 45 pints of each of the two existing types of drink must be used to make 50 pints of a mixture that is 75% pure fruit juice.

Let x be the number of pints of the first fruit juice (i.e., 30%) and y be the number of pints of the second fruit juice (i.e., 80%).

Since the total number of pints to make the 75% pure fruit juice is 50, it can be represented using the equation:

x + y = 50 -----(1)

Also, x pints of the first juice = 0.30x, y pints of the second juice = 0.80y and 50 pints of the mixture to be produced = 50(0.75)= 37.5. Therefore:

This is represented as ;

30% × x + 80% × y = 50 of 75%

Make x in the subject x + y = 50

Substitute:

x = 50 - y in 30% × x + 80% × y = 50 of 75%

0.30 (50 - y) + 0.8 × y = 50 of 0.75

15 - 0.3y + 0.8y = 37.5

Collect like terms :

-0.3y + 0.8y = 37.5 - 15

0.5y = 22.5

y = 45

Recall that :

x = 50 - y

x = 50 - 45

x = 5
