NO, THE ANSWER IS NOT 40.

The solution to the problem is as follows:

If they vary directly, their ratio is always equal to the same number.
Since 10/2 = 5, any p/q has to = 5.
So p/20 = 5

p = 5 x 20 = 100

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

This can be solve using the formula
F = P(1 - i)^nwhere F is the future populationP is the initial populationi is the percent population declinen is the number of years
F = 951,300 ( 1 - 0.014)^5F = 886,548 will be the population in 2005

Jose, baulus, and George are having a disagreement over interest rates. Jose says that 6 3/4% can be expressed as 6.75%. George

Answer:

Jose and George are correct

Baulus is incorrect

Step-by-step explanation:

Given

$6\frac{3}{4}$ %

Required

Compare the above expression with

Jose: 6.75%.

George: 0.0675

Baulus: 0.0675%

The expression  $6\frac{3}{4}$ % is given as a mixed fraction;

In Jose's case, he simply converted it to decimal

Converting $6\frac{3}{4}$ % to decimal;

First, we need to convert to improper fraction

$6\frac{3}{4}$ % in improper fraction is $\frac{27}{4}$ %

Then, we divide the numerator by the denominator

$\frac{27}{4}$ % = 6.75%.

Hence, Jose is correct

In George's case, he solved further by removing the % from Jose's answer.

% means divided by 100; In other words, x% means that we divide x by 100

So, 6.75% means we divide 6.75 by 100

$\frac{6.75}{100}$ = 0.0675

Hence, George is also correct

But same can't be said of Baulus;

Baulus converted $6\frac{3}{4}$ % as 0.0675%

This means that he converted $6\frac{3}{4}$ as 0.0675 then he appended it with the percentage sign (%)

Since $6\frac{3}{4}$ is not equal to 0.0675, then we can conclude that Baulus is incorrect
