Answer:
Area of red band is 
Step-by-step explanation:
We know that area of square = 
Please refer to the attached figure, we have to calculate the area of red band.
Required area = Area of square <em>ABCD </em>- Area of <em>purple square
</em>
Side of purple square = 
So, area of purple square = 
<em>ABCD </em>is a square with purple square at the center and there is symmetry in the figure.
So, width of red band towards both the end is 5 inches.
Required area = 
Using formula 
Hence, Area of red band is
Answer:
A
Step-by-step explanation:
∠4 and ∠8 are corresponding angles
corresponding angles are congruent ( equal to each other )
so if ∠4 = 100° then ∠8 also equals 100°
Answer:
q(2)=20
Step-by-step explanation:
Substitute the 2 into the 10m, which will be 10(2). Then, multiply those two numbers, and you'll get 20
Answer:
1394
Step-by-step explanation:
Set up equation to find the number:
Variable n = number
65/100 = 1105/n
Cross multiply:
65 × n = 100 × 1105
65n = 110,500
n = 1700
Check your work:
1700 × 65%
Convert percentage into decimal:
1700 × 0.65
1105
Correct!
Find 82% of 1700:
Variable x = 82% of 1700
82/100 = x/1700
82 × 1700 = 100 × x
139,400 = 100x
1394 = x
Check your work:
1700 × 82%
1700 × 0.82
1394
Correct!
