Vision a box...


Side box 5cm
bottom right long side 4 cm
front bottom short side 3cm


The volume of this box is

If n is a positive integer divisible by 7, and if n < 70, what is the greatest
possible value of n?


A. 49
B. 56
C. 63
D. 69 - CORRECT ANSWERS The correct answer is (C) 63. If you
know one multiple of a number, you can find the other multiples by adding and
subtracting that number. The number 70 is divisible by 7. The greatest multiple
that is less than 70 will be 70 − 7 = 63.

, Blair's average (arithmetic mean) on two physics tests is 7. What should Blair's
score be on the next test to have an overall average of 8 for all the tests?


A. 7
B. 8
C. 9
D. 10 - CORRECT ANSWERS The correct answer is (D) 10. The
arithmetic mean is defined as the sum of the terms divided by the number of
terms.
7 = sum / 2
14 = sum


Adding the next test's score will change the average to an 8, and the total terms
to 3.
8 = (14 + new score) / 3
24 = 14 + new score
10 = new score
