Answer: 30% of decrease
Step-by-step explanation:
$13.95 - $10 = $3.95
$13.95___100%
$3.95___x= 28.31%
(3.95*100) / 13.95 = 28.31 = 30
Answer:
D) x² -x - 10 =0
Step-by-step explanation:
Given that
L.C.M
⇒ 
⇒ 9 x + 54 = 9 x² - 36
⇒ 9 x² - 36 - 9x - 54 =0
⇒ 9 x² - 9x - 90 =0
⇒ 9(x² -x - 10 ) =0
⇒ x² -x - 10 =0
Answer:Here are some more problems to solve.
Calculate the volume of a paperback book with the following dimensions:
Length = 12 cm
Width = 3 cm
Height = 20 cm
Calculate the volume of a steel bar with the following dimensions:
Length = 5 cm
Width = 2 cm
Height = 30 cm
Now determine the density of the steel bar if its mass is 2.34 kg. (Hint: Convert to grams first.)
A cork has a volume of 5.0 cm3 and a mass of 1.2 grams. Calculate its density.
Water has a density of 1 g/cm3. If you placed a cork and a steel paper clip in a jar of water, what do you think would happen? Use your knowledge of density to explain the outcome.
