Jose, baulus, and George are having a disagreement over interest rates. Jose says that 6 3/4% can be expressed as 6.75%. George thinks that 6 3/4% can be expressed as 0.0675. Baulus remembers converting percents to equivalent decimals and thinks it can be expressed as 0.0675%. Who is correct, and who is incorrect? Explain each choice.

Jose and George are correct

Baulus is incorrect

Step-by-step explanation:

Given

%

Required

Compare the above expression with

Jose: 6.75%.

George: 0.0675

Baulus: 0.0675%

The expression % is given as a mixed fraction;

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

Converting % to decimal;

First, we need to convert to improper fraction

% in improper fraction is %

Then, we divide the numerator by the denominator

% = 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

= 0.0675

Hence, George is also correct

But same can't be said of Baulus;

Baulus converted % as 0.0675%

This means that he converted as 0.0675 then he appended it with the percentage sign (%)

Since is not equal to 0.0675, then we can conclude that Baulus is incorrect

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
