Answer:
-4
Step-by-step explanation:
Since the total score <em>I</em><em>n</em><em>c</em><em>r</em><em>e</em><em>a</em><em>s</em><em>e</em><em>d</em><em> </em>by eight than the two matching cards must have been -4.
(total of four cards) + (two matching cards) = total score
(total of four cards) + (two cards × -4) = total score
(total of four cards) - 8 = total score
* take away two matching cards by adding 8 on both sides*
(total of four cards) = total score + 8

I am going to make what is hopefully not an incorrect assumption and say that since the segmentXSZ is black and the other lines are blue, that XS is congruent to ZS. If that be the case we have a side in each triangle that is congruent to each other and an angle that is marked as congruent. Angles XSW and ZSY are vertical angles. By definition, vertical angles are congruent. In each triangle, then, we have an angle, a side and an angle which gives us the congruency postulate ASA.
Answer: The weight of the iceberg at the end of the day will be 449,100 lbs.
Step-by-step explanation: The question is solved by first calculating what the loss of weight is during the day. The question indicates that it will lose .2%. In order to calculate the loss you need to multiply 450,000 x .002, which equals 900. Next, we subtract the weight loss from the original weight to determine the end of day weight. 450,000 - 900 = 449,100 lbs.
