Problem 1
The largest value would be 1 and the smallest would be
-1.
To get a product of 1, either all are 1 or two of the
variables are -1 and the other one is 1.
Largest value = (1)^2 * (1)^3 * (1)^4 =1
Smallest value = (- 1)^2 * (- 1)^3 * (1)^4 = -1
The difference is:
largest value – smallest value = 1 – (-1) = 2
<span>Therefore the answer is letter D.</span>
Problem 2
% loss = (final price – initial price) * 100%/ initial
price
where, final price per dozen = ( $2.50 / piece) (12 piece
/ dozen) = $30
Therefore,
% loss = ($30 - $33) * 100 / $33
% loss = - 300/ 33 = 9 1/11
<span>Therefore the answer is <span>letter C.</span></span>
We have that
Her house is -----------------------24 feet tall
Her model is----------------------- 8 inches tall
The inch is a unit of length used primarily in the imperial and U.S.
customary measurement systems, representing 1/12 of a foot
in
=ft * 12.000
24
feet=12*24=288 inches
Her house is -----------------------288 inches tall
Her model is----------------------- 8 inches tall
288/8=36 scale of reduction
Her
brother is 5 feet tall
<span>The figurine in the model that
represents her brother (5/36)</span>=0.138889 feet
<span>0.138889*12=1.67 inches</span>
D I got it in my test and it’s correct
I think that the answer is A.
