Find the square root of 85 correct to the nearest tenth.
A. 9.1 B. 9.2 C. 9.3 D. 9.4 |
B. 9.2 |
One way to solve this is to square each of the suggested answers to see which is close to 85. Thus 9.1 • 9.1 = 82.81 9.2 • 9.2 = 84.64 9.3 • 9.3 = 86.49 9.4 • 9.4 = 88.36 To find squares of 9.2 and 9.3 are near 85. Find the difference between the square of each of these numbers and 85.
(9.2) 85.00 - 84.64 = 0.36 (9.3) 86.49 - 85.00 = 1.49 The square 9.2 is closer to 85 than the square 9.3. Therefore, the square root of 85, to the nearest tenth, is 9.2. |

The perimeter of a rectangle is 38 inches. If the length is 3 inches more than the width, find the width.
A. 17½ inches B. 8 inches C. 11 inches D. 14½ inches |
B. 8 inches |
perimeter of a rectangle is the sum of its four sides. If x equals its width, then x + 3 equals the length. (The length is 3 inches more than the width.) From this, you can write an equation to find the perimeter. (Use the formula 2w + 2l = P.) x + x + (x + 3) + (x + 3) = 38 To solve for x, combine similar terms. 4x + 6 = 38 4x = 38 - 6 4x = 32 x = 8 (inches) |
