Answer:
s = (14 + 7 + 11)/2 = 32/2 =16
=> area = sqrt(16*(16-14)*(16-11)*(16-7)) = ~37.95
=> h = 2*Area/Base = 2*37.95/14 = 5.42
Given:
The triangle ABC is reflected over the x-axis.
The distance between point A and A’ is 14.
To find:
The distance between the x-axis and A’.
Solution:
If a figure is reflected across the x-axis then the corresponding parts are mirror image of each other about the x-axis.
It means the distance between A and x-axis is same as the distance between x-axis and A'.
The distance between point A and A’ is 14.
Let d be the distance between the x-axis and A’. Then,




Therefore, the correct option is 1.
The quotient to this answer is -x^2-5x-59
The original ratio is 5/2.
If Marcus adds 1 part of each to the mixture, the new ratio of red to white becomes
5+1 6 2
------ = ----- = ----
2+1 3 1
The new ratio of red to white is 2:1.
Answer:
C. The expression is y = 1200x + 100 , and the cost is $1,300.
Step-by-step explanation:
<u>Given</u> :
- Let y be the total cost and x be the number of TVs
- Membership costs $100
- If applied, TV costs 80% of original price
<u>Solving</u> :
- y = 1200x + 100 [given x = 1]
- y = 1200 + 100
- y = 1300
- Total cost is $1300
