Answer:
There was a increase of 1.7% over these three years
Step-by-step explanation:
Multipliers:
For a decrease of a%, we multiply by: 
For a increase of a%, we multiply by: 
What was the percentage increase/decrease of groundhogs over these three years?
Decrease of 12%(multiplication by 0.88).
Increase of 6%(multiplication by 1.06).
Increase of 9%(multiplication by 1.09).
After these three years:
0.88*1.06*1.09 = 1.017
1.017 - 1 = 0.017
0.017*100% = 1.7%
There was a increase of 1.7% over these three years

Answer:</h3>
He will need at least 122 tiles
<h3>
Step-by-step explanation:</h3>
Get the area of the tiles
5*14= 70 square inches per tile
Divide the floor area by the tile area
8,500/70
121.428571
Round up
122
Answer:
ALEKS Corporation
Software company
Step-by-step explanation:
Draw a diagram to illustrate the problem as shown below.
When the smaller gear rotates through a revolution, it sweeps an arc length of
2π(4) = 8π inches.
Part 1
The same arc length is swept by the larger gear. The central angle of the larger gear, x, is
7x = 8π
x = (8π)/7 radians = (8π)/7 * (180/π) = 205.7°
Answer: 205.7° (nearest tenth)
Part 2
When the larger gear makes one rotation, it sweeps an arc length of
2π(7) = 14π inches.
If the central angle for the smaller gear is y radians, then
4y = 14π
y = 3.5π radians = (3.5π)/2π revolutions = 1.75 revolutions
Answer:
The smaller gear makes 1.75 rotations

How to Graph a Linear Inequality
First, graph the "equals" line, then shade in the correct area.
There are three steps:
1.) Rearrange the equation so "y" is on the left and everything else on the right.
2.) Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
4.) Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
Hope This Helps! Have A Nice Day!!
