Answer:
-2.5
Step-by-step explanation:
The point is between -2 & -3
17.3 million smartphones were sold in 2009
I don't think there is any difference, because 8-15=-7, and 8+(-15)=-7, because if you remove the parentheses, you will also get 8-15.
Please mark brainiest! Will really really appreciate it!
The width is between 2 feet and 4 feet
Taking the average, 1/2 (2 + 4) = 4 feet
The length is between 3 feet and 6 feet
Taking the average, 1/2 (3 + 6) = 4.5 feet
Area of one panel = 4 x 4.5 = 18 ft²
Area of 5 panels = 18 x 5
Area of 5 panels = 90 ft²
The estimated area of the 5 panels is 90 ft².
John's estimate is not reasonable as 140ft² is way too high from the average of 90 ft².
<em>Even taking the biggest possible length and width</em>
<em>The area of 1 panel = 4 x 6 = 24 ft²</em>
<em>The area of 5 panels = 24 x 5 = 120 ft²</em>
<em>Even taking the highest possible estimate of 120 ft², John's estimate is still way too high</em>
