F(x) = [x] - 2 + 8
[x] is the notation for 'greatest integer function'
f(-1.8) = [-1.8] - 2 + 8 = -2 -2 + 8 = 4
The answer is 4
Given:
Area of rectangle = 
Width of the rectangle is equal to the greatest common monomial factor of
.
To find:
Length and width of the rectangle.
Solution:
Width of the rectangle is equal to the greatest common monomial factor of
is



Now,

So, width of the rectangle is
.
Area of rectangle is

Taking out GCF, we get

We know that, area of a rectangle is the product of its length and width.
Since, width of the rectangle is
, therefore length of the rectangle is
.
<span>The tens place of the given
number 974.362 is 7. To round it to the nearest ten then is should
remain the same because the ones digit is equal to 4, the tens digit so be
retained because it is less than 5.</span>
<span>So the
answer is 970</span>
Cost of the skateboard = $77.99
Amount that he already has = $20
$77.99 - $20 = $57.99
He still needs <u>$57.99</u>
He earns $6 for every lawn he mows.
$57.99 ÷ 6 = 9.65
He needs to move <u>10 lawns </u>to earn that $57.99.
He can mow 3 lawns a weekend.
10 ÷ 3 = 3 1/3
He needs to work on <u>4 weekends</u> to mow the 10 lawns.
Answer: It will take him 4 weekends to save enough to buy the skateboard.
