Fill in each slot in the square with variables <em>a</em>, <em>b</em>, <em>c</em>, <em>d</em>, and <em>e</em>, in order from left-to-right, top-to-bottom. In a magic square, the sums across rows, columns, and diagonals all add up to the same number called the <em>magic sum</em>.
The magic sum is -3.9, since "diagonal 2" (bottom left to top right) has all the information we need:
3 + (-1.3) + (-5.6) = -3.9
Use this to find the remaining elements
<em>a</em> + <em>b</em> + (-5.6) = -3.9
<em>c</em> + (-1.3) + <em>d</em> = -3.9
3 + <em>e</em> + 0.02 = -3.9
<em>a</em> + <em>c</em> + 3 = -3.9
<em>b</em> + (-1.3) + <em>e</em> = -3.9
(-5.6) + <em>d</em> + 0.02 = -3.9
- diagonal 1 (top left to bottom right):
<em>a</em> + (-1.3) + 0.02 = -3.9
You will find
<em>a</em> = -2.62
<em>b</em> = 4.32
<em>c</em> = -4.28
<em>d</em> = 1.68
<em>e</em> = -6.92
Answer:
what u need help with
Step-by-step explanation:
Answer:
(a). 32 copies
(b). $3060
Step-by-step explanation:
<u>Solution for (a):</u>
<u />
P = 60c + 1800
If P is $3720 then;
3720 = 60c + 1800
60c = 3720 - 1800 = 1920
c =
= 32 copies
<u>Solution for (b):</u>
<u />
P = 60c + 1800
If c is 21 then;
P = $60(21) + $1800
P = $1260 + $1800
P = $3060
Answer:
10.5 miles
Step-by-step explanation:
75 divided by 50 is 1.5
1.5 times 7 is 10.5
Answer & Explanation:
As we know exterior angle of polygon is supplementary of the interior angle. So we will calculate interior angle first. Since decagon is regular so all angles will be same. Each exterior angle of a decagon will be 36°.
