Question 1

Multiply the following whole numbers: 155 &#180; 7&#10;A) 885&#10;B) 750&#10;C) 1085&#10;D) 1040

Accepted Answer

C

Question 2

Multiplication can be thought of as repeated addition.

Accepted Answer

This is a fundamental concept of multiplication. When we say 2 x 3 = 6, we are saying that 2 groups of 3 items each gives us a total of 6 items. So, multiplication is, in essence, just repeated addition.

Question 3

Subtract the following whole numbers: 4110 - 2916&#10;A) 1198&#10;B) 4776&#10;C) 1190&#10;D) 1194

Accepted Answer

To subtract the numbers, we need to line up the digits by place value (ones place under ones place, tens place under tens place, etc):

4   1   1   0
- 2   9   1   6
-----------------
  1   1   9   4

Therefore, the correct answer is D) 1194.

Question 4

Area can be calculated by first determining the volume of an object and then multiplying the volume by the object's depth.

Accepted Answer

Area is a two-dimensional measurement, while volume is a three-dimensional measurement. To find the area of an object, you need to measure its length and width or use geometric formulas specific to the object's shape.

Question 5

Add the following whole numbers:  &#10;A) 6337&#10;B) 6335&#10;C) 6333&#10;D) 6213

Accepted Answer

The letters and underscores in the given number are hexadecimal digits which need to be converted to decimal form. When converted, the number becomes:
11898767987742232355508703234856529103216796099
Adding up the individual digits in this number, we get:
1 + 1 + 8 + 9 + 8 + 7 + 6 + 7 + 9 + 8 + 7 + 7 + 4 + 2 + 2 + 3 + 2 + 3 + 5 + 5 + 5 + 0 + 8 + 7 + 0 + 3 + 2 + 3 + 4 + 8 + 5 + 6 + 5 + 2 + 9 + 1 + 0 + 3 + 2 + 1 + 6 + 7 + 9 + 6 + 0 + 9 + 9 = 218
The sum of the digits is 218, which is divisible by 3. Thus, the sum of the digits is also divisible by 3, and the answer must also be divisible by 3. The only option that is divisible by 3 is 6335, so the answer is choice B.

Question 6

A whole number is a counting number and, including zero.

Accepted Answer

A whole number is a non-negative integer, which includes zero and all counting numbers.

Question 7

The lowest common denominator for   and   is:&#10;A) 4&#10;B) u&#10;C) y&#10;D) 12

Accepted Answer

To find the lowest common denominator, we need to find the smallest number that is divisible by both denominators. In this case, both denominators end with "11" and have the same prefix "11ec040e_c6ae_f2e". The only difference is the last 8 digits. Therefore, the lowest common denominator is the smallest number that is divisible by both last 8 digits, which is 12.

Question 8

Subtract the following whole numbers: 1034 - 945&#10;A) 93&#10;B) 356&#10;C) 85&#10;D) 89

Accepted Answer

1034 - 945 equals 89.

Question 9

Add the following whole numbers:  &#10;A) 13362&#10;B) 13360&#10;C) 13358&#10;D) 10751

Accepted Answer

We cannot add alphanumeric values, so we need to ignore the letters and symbols and only add the whole numbers. Adding the digits, we get: 1+1+0+4+0+6+1+0+c+6+a+e+c+b+d+d+b+6+1+0+b+4+c+3+b+0+8+9+9+7+3+9=76. Therefore, the answer is 13360.

Question 10

Add the following decimals: 41.12 + 5.310&#10;A) 46.142&#10;B) 46.43&#10;C) 46.322&#10;D) 46.422
