8/7 each side of the expression both go up by 1
There are four gray rectangles in the graph, showing 2 different probabilities. Add together the areas of the two rectangles located on the right side:
0.35+0.05 = 0.40 (answer)
Answer: 
Step-by-step explanation:
Let be "x" the time in minutes that will take him to mow the entire park.
You know that he can mow 13 square feet in 1 minute and he has to mow 14,623 square feet.
Then, you can write the following proportion:
Solving for "x", you get:
To write that improper fraction as a mixed number:
- The quotient when you divide the numerator by the denominator of the fraction obtained, is 
(This will be the whole number).
- The remainder of that division is 
(This will be the numerator of the fraction).
- The denominator does not change.
Then:
Answer:
Step-by-step explanation:
You want the external angle to be 45°.
If n = number of sides, the external angles are each 360°/n = 45°
n = 360/45 = 8
The shape is a regular octagon.
1. X/Y = Z
if x = 6, y = 2, then z = 3, not even
if x = 6, y = 3, then z = 2, even
<span>2. Z=XY </span>
so (z)^2 = 2*k (because x*y*z = 2k, where k is an integer)
<span>Sufficient, as if square of an integer is even ,then the integer is even</span>
