Answer:
BC = 10 units
Step-by-step explanation:
From the picture attached,
It's given that AD and BE are the parallel sides.
AC and DC are the transversal lines intersecting the parallel lines.
In ΔADC and ΔBEC,
∠DAC ≅ ∠EBC [Corresponding angles]
∠ADC ≅ ∠BEC [Corresponding angles]
ΔADC ~ ΔBEC [By AA property of similar triangles]
By the property of similar triangles,
Corresponding sides of the similar triangles are proportional.
![\frac{AC}{BC}=\frac{DC}{EC}](https://tex.z-dn.net/?f=%5Cfrac%7BAC%7D%7BBC%7D%3D%5Cfrac%7BDC%7D%7BEC%7D)
![\frac{AB+BC}{BC}=\frac{DE+EC}{EC}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%2BBC%7D%7BBC%7D%3D%5Cfrac%7BDE%2BEC%7D%7BEC%7D)
![\frac{2.5+BC}{BC}=\frac{2+8}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%2BBC%7D%7BBC%7D%3D%5Cfrac%7B2%2B8%7D%7B8%7D)
![\frac{2.5}{BC}+1=\frac{10}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7BBC%7D%2B1%3D%5Cfrac%7B10%7D%7B8%7D)
![\frac{2.5}{BC}=\frac{5}{4}-1](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7BBC%7D%3D%5Cfrac%7B5%7D%7B4%7D-1)
![\frac{2.5}{BC}=\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B2.5%7D%7BBC%7D%3D%5Cfrac%7B1%7D%7B4%7D)
BC = 10
Answer for above question
Answer:
B
Step-by-step explanation:
If stuck on a graphing question you can use Desmos Graphing Calculator, it's a free online resource.
Since you gave no parenthesis: Remember to follow PEMDAS. Note that anything with the power of 0, the answer will become 1
10^0 = 1
8 x 1 = 8
8 is your answer

The employee discount is 30% off. Here's the process to find this answer:
Calculate the difference between the original price and the discounted price. We're trying to find the percentage of the discount, not the percentage 38.50 is of 55.
55 - 38.5 = 16.5
Multiply the difference by 100 as part of the percentage formula. (is over of is equal to the percentage over one hundred)
16.5 * 100 = 1,650
Divide your result by 55 as the final part of the percentage formula.
1,650 / 55 = 30
