Answer:
No.
Step-by-step explanation:
A polyhedron should follow the formula F+V=E+2.
The above measurements do not follow this formula hence a polyhedron is not possible.
Answer:
0.3125
Step-by-step explanation:
Use definition of geometric probability:

In your case,
Total Length = 8 miles
Desired Length = 7 - 4.5 = 2.5 miles,
so the probability is

Answer:
slope = -2
Step-by-step explanation:
Slope is the rate of change, it tells you how much you go up or down when you move 1 to the right.
To find the slope you just need 2 points
Slope = 
The easiest points to use are the intercepts ( points on the x,y axis)
On the graph you will see the line cross the y-axis at 6 and x-axis at 3.
The points are (0,6) and (3,0)
Slope = 
Also an easy way to check the sign of the slope is to move your finger along the line from left to right.
If you are going uphill, then slope is ALWAYS positive
If you are going downhill, then slope is ALWAYS negative
Answer
the answer is D
Step-by-step explanation:
the square root of 300 is 17.3
so there for it lies between 17 and 18
Given:
The phrase is "Wally mowed two more lawns than he mowed last week".
To find:
The expression that models the given phrase.
Solution:
Let the number of lawns mowed by Wally last week be n.
We know that, we use plus sign "+" for "more".
If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.
Lawns mowed this week = 
The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.
Therefore, the correct option is A.
