The average (A) of two numbers, m and n, is given by the formula A = m+t/2 . Find
the average of the two numbers 36 and 72.
The solution is

The dogs rescued this year were 1738.

A ratio is a way to show a relationship or compare two numbers of the same kind. We use ratios to compare things of the same type.

Given that, Last year the animal rescue centre rescued 2520 dogs and cats in the ratio of 3:2. This year, the number of dogs rescued has increased by 15%.

Let the number of dogs and cats be x,

3x+2x = 2520

5x = 2520

x = 504

The number of dogs were = 3*504 = 1512

This year, 1512*115/100 = 1738.8

Hence, The dogs rescued this year were 1738.

Translations do not change the slope of the line, so the original line and the transformed line are always a parallel option (B) is correct.

Lines that intersect at a right angle are named perpendicular lines. Lines that are always the same distance apart from each other are known as parallel lines.

As we know, parallel lines never intersect.

Parallel lines result from changing the y-intercept while keeping the slope constant.

The original line and the transformed line are always parallel since translations do not alter the slope of the line.

Thus, translations do not change the slope of the line, so the original line and the transformed line are always a parallel option (B) is correct.

The equation which represents the relationship between X values and Y values can be found by deriving the equation of line using slope intercept form. The equation of line is 3x - 5y = 25.

How to find equation of line using slope intercept form?

Equation of line using slope intercept form is y = mx + b

where m is slope of the line and b is y-intercept

The slope intercept can be used to form equation of line using two points on the line.

According to the given question:

The two points which lie on the line are (x, y) = (5, -2) and (x', y') = (0, -5)

Slope of the line m = y' - y/x' - x

                               = (-5 +2)/(0 - 5)

                               = 3/5

Now y intercept b = y - mx

                              = -2 - (3/5. 5)

                              = -5

Therefore the required equation of line is y = 3/5x - 5

On simplifying further 3x - 5y = 25

The probability that a student is in the choir or band or both is 0.911

Probability is the likelihood that an event will happen. This can range from an event being impossible to some likelihood to being absolutely certain. In math terms, probability is on a scale from 0 to 1. Zero means the event is impossible, like rolling a seven on a die that only has digits from 1 to 6. One is an event that will happen, it is certain.

Total number of students in the school = 450

number of students in choir = 110

number of students in band = 240

number of students in both = 60

Probability a student chosen at random is in the choir or band or both is

110/450 + 60/450 + 240/450

= 410/450 which is 0.911

In conclusion, the probability of a student being in music, or band or both is 0.911

It takes 8 months for the investment to grow to $6000 if interest was compounded quarterly.

What is compound interest?
The interest charged on a loan as well as deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest. The main distinction between compound as well as simple interest is this.

Given:

Principal amount = $5000

Annual amount interest = 2.6%

Compounded quarterly = 4

Final amount = $7000

Formula:

A = P(1 + r)^4n - 1

A is the quarterly compounded interest.

P would be the principal amount.

r is the quarterly compounded rate of interest.

n is the number of periods.

Solving it:

7000 = 5000 (( 1 + 0.026))^ 4t -1

7/5 = (( 1 + 0.026))^ 4t

7/5 = (1.026)^ 4t -1

ln (7/5) = 4t ln (1.006) - ln 1

t = 7.61 months

t ~ 8months

Hence, it takes 8 months for the investment to grow to $6000 if interest was compounded quarterly.
