Since beth was born, the population of her town has increased at a rate of 850 people per year. On beth 9ths birthday, the total
faltersainse [42]

Answer: There will be 313600 population on beth's 16 birthday.

Step-by-step explanation:

Since we have given that

When Beth was born , the population of her has increased = 850 per year

Let the initial population be x

and let the number of year be n

So, our linear equation becomes,

x+850n

On her 9th birthday,

The population becomes 307,650.

So, it becomes,

x+850\times 9=307650\\\\x+7650=307650\\\\x=307650-7650\\\\x=300000

So, initial population becomes 300000.

Now, on 16th birthday,

x+850n\\\\300000+850\times 16=313600

So, there will be 313600 population on beth's 16 birthday.

A report card shows that a student earns 21 21 points on a test with a total of 25 25 points. What percentage of the total point
Ostrovityanka [42]

When a report card shows that a student has earned 21 points on a test with a total of 25 points, it can be concluded to state that the student has secured 84 percentage of the total points of the test.

The computation of the percentage of points secured by the student out of the total available points in a test can be done using the generalized formula and the use of provided information into the same as below,

Percentage = Scored Secured / Total Points x 100

Percentage = 21 / 25 × 100

Percentage = 0.84 × 100

Percentage = 84 percentage.

Therefore, the student has earned 84 percentage of total points on a test.

The sum of two numbers is odd. Can the quotient of the two numbers be an odd number?
Natalka [10]

Answer: No.

Step-by-step explanation:

I guess that here we have the statement:

If the sum of two numbers is odd----> can their quotient be an odd number?

first, for n an integer number, we have that:

an odd number can be written as 2n + 1

an even number can be written as 2n.

The sum of two numbers is only odd if one of them is odd and the other even.

Then we have a number that is 2n and other that is 2k + 1, for n and k integer numbers.

Now, let's see if the quotient can also be an odd number.

One way to think this is:

There is an odd number such that when we multiply it by another odd number, the result is an even number?

no, and i can prove it as:

let 2k + 1 be an odd number, and 2j + 1 other.

the product is:

(2k + 1)*(2j + 1) = 2*(2*k*j + k + j) + 1

and as k and j are integers, also does 2*k*j + k + j, so:

2*(2*k*j + k + j) + 1 is an odd number.

This says that the product of two odd numbers is always odd, then we never can have that the quotient between an even number and an odd number is odd.
