Question 5

Multiply: 1(-4)(-6)
A) -18
B) 3
C) -10
D) -9
E) 24

Accepted Answer

Multiplying 1 by anything does not change the value, so we can ignore the 1. Then, (-4)(-6) is equal to 24, so the answer is E.

Question 6

Multiply: 
A) -140
B) -100
C) -80
D) 2
E) 1056

Accepted Answer

We can use a calculator or long multiplication method to multiply these numbers. The result is a large negative number, but we only need to look at the last digit to determine the answer. The last digit of the product is 6 x 1, which is 6. Therefore, the answer must end in 6. The only choice that ends in 6 is E, which is 1056.

Question 14

Multiply: 
A) -285
B) 288
C) 285
D) -280
E) 273

Accepted Answer

To multiply these two numbers, we can use the standard multiplication algorithm. Starting from the rightmost digit of the second number, we multiply each digit by the entire first number, carrying over any extra digits as needed.

In this case, we get:

```
                     1  1  e  b  6  9  d  a
                  ×  9  f  5  0  5  1  7  9
                  ------------------------
                     8  6  b  a  5  8  0  9
           +     1  0 7 5 5 5 7  4  4
           +   e b  6 9 d a               
           ------------------------       
           =   c 3 f 1 b 7 8 1 1           
```

Converting the hexadecimal result to decimal, we get:

```
c3f1b7811 = 128664838289
```

Taking the last digit of this number (which corresponds to the units digit of the decimal expression), we get 9. This matches the units digit of choice C, so C is our answer.

A) -6 
B) 2 
C) -4 
D) -3 
E) 0

Accepted Answer

To find the average daily low temperature, we need to add up all the low temperatures for the 10-day period and divide by 10. Adding up the given low temperatures, we get 32. Dividing by 10, we get an average low temperature of -4. Therefore, the best choice is C) -4.
