Answer:
D
Step-by-step explanation:
The odd one out would have to be 7:41 because 7x6 is 42 which is the pattern thats happening
Steps
1) 100%-15%=85%
2) 9.99×0.85=11.49
3) 11.49×0.05+11.49=8.92
they cost$8.92
Answer:
<h3>C.) The area of EFGH is always ¹/₂ of the area of the rectangle. </h3>
Step-by-step explanation:
If EG is parallel to the side of the rectangle then lenght of EG is equal to width of rectangle.
If F and H are midpoints of sides of rectangle then FH is parallel to the side of rectangle {wich is perpendicular to the side parallel to EG}. That means the lenght of FH is equal to lenght of rectangle, and FH is perpendicular to EG.
Then FH is sum of hights of triangles EFG and EHG , and the area of EFGH is sum of areas of triangles EFG and EHG .
So the area of the rectangle:
The area of the kite:
No matter the height of the triangles, so no matter the location of the EG
Answer:
39.91 degrees.
Step-by-step explanation:
Formula
Sin(A)/a = Sin(B) / b
Givens
Solution
Sin(84)/31 = Sin(B)/20
20*Sin(84) / 31 = Sin(B)
Sin(B) = 0.6416
B = 39.91 degrees.
====================
This looks like it is right, but you should check. Let h be the height opposite angle A.
h/20 = sin(39.91)
h = 20*sin(39.91)
h = 12.83
31 has to be longer than that amount (which it is.) So there is one solution.
