Answer:
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%
<em>The expression </em><em>% is given as a mixed fraction;</em>
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
Answer:
Step-by-step explanation:
<em>(17).</em> g(x) = x³ + 4x
f(x) = 4x + 1
( f × g )( x ) = ( x³ + 4x )( 4x + 1 ) = <em>4 </em><em> + x³ + 16x² + 4x</em>
<em>(19).</em> f(t) = 4t - 4
g(t) = t - 2
( 4f + 3g )( t ) = 4(4t - 4) + 3(t - 2) = 16t - 16 + 3t - 6 = <em>19t - 22</em>
<em>(21).</em> h(t) = t + 3
g(t) = 4t + 1
h(t - 2) + g(t - 2) = ( t - 2 ) + 3 + 4( t - 2 ) + 1 = t + 4t - 2 + 3 - 8 + 1 = <em>5t - 6</em>
