Answer:
Option C is right
Step-by-step explanation:
The figure is a kite divided into 4 right triangles
Top two triangles are congruent and also bottom two triangles
Since top half angle is 45 we have height = base = 45 for top triangle
Top triangle right side area = 1/2 base x height = 1/2 (2.5)(2.5)
Area of two triangles at the top = 2.5 x 2.5 =6.25
Now bottom triangles each has base 6m and height same as 2.5 m
Hence area of two triangles at the bottom=2(1/2 )(6)(2.5)
=15
Together the total area of the figure = 6.25 +15 = 21.25 m^2
Option C is right.
X = 6
24 divided by 4 equals 6
You can solve this in a long way so that you will understand
the relationship of the increase in the number of memberships sold.
First week = 5 memberships
Second week = 8 memberships (5 + 3)
Third week = 11 memberships (8 + 3)
Fourth week = 14 memberships (11 + 3)
Fifth week = 17 memberships (14 + 3)
Total after 5 weeks = 55 memberships sold (5 + 8 + 11 + 14 +
17)
3000/40 uniforms=$75
Returned some for $40
$75-40=$35 difference
