Answer: 2

Step-by-step explanation: You round up when the number is 5 or higher. In this case since it’s 1.9, you can just round to 2

Round off 1.94155 to thousands, when you place each of the decimal fraction into their place value you will discover that 9 is tenth, 4 is hundredth and 1 is thousandth. Since the number that follows 1 being the thousandth is 5 you will need to round up 5 to become 1 and add to the 1 in thousandth to become 2. Therefore the answer is 1.942

A fenced in rectangular region with the dimensions 4 yards by 8 yards is suddenly expanded by the same distance in each dimensio

Korolek [52]

Answer:

The distance added to each dimension is 2 yards.

Step-by-step explanation:

The initial dimensions of the rectangular fence is 8 yards by 4 yards.

The initial area of the rectangular fence = area of a rectangle

area of a rectangle = length x width

So that,

The initial area of the fence = 8 x 4

= 32

The initial area of the fence is 32 square yards.

But, with the new dimensions, area = 60 square yards.

(4 + x) x (8 + x) = 60

$x^{2}$ + 12x + 28 = 60

$x^{2}$ + 12x - 32 = 0

(x + 14) = 0 or (x - 2) = 0

x = -14 or x =2

Thus, x = 2

The distance added to each dimension is 2 yards.
