Dividing by a fraction is the same as multiplying by the reciprocal. so dividing by 1/2 is the same as multiplying by 2/1, or 2. so (3/4)/(1/2) = (3/4)*2 = 6/4 = 1 and 1/2
There are none. The factors are 1, 5, 613, and of course 3065 and none are perfect squares.
The answer is the first option, 28.6 m^2.
First, you know that the area of the square is 4 × 4 = 16 m^2.
The area of a regular circle is π × radius^2, but for a quarter circle, that changes to (π × radius^2)/4. We use 3.14 as π, and 4 is the radius, so we get (3.14 × 4^2)/4 = 50.24/4 = 12.56. Now we just need to add this to our original 16 m^2 to get the answer of 28.56, which rounds to 28.6 m^2. I hope this helps!
Factor 42 into factor pairs and add them and see which ones add to -13
remember both must be negative
-1-42=-43 nope
-2-21=-23 nope
-3-14=-17 nope
-6-7=-13 yep
the numbers are -7 and -6
