Answer:
60%
Step-by-step explanation:
The required markup percentage is 60%. The store bought the shoes for 50 dollars and got 30 dollars out of it when they sold it. And that mark up percentage is 60%. 30 dollars is 60 percent of the cost of the shoe. I don't know if you will understand this but this is the answer.
<h3>
First Method:</h3>
<u>Using cosine rule</u>:
<h3>
Second Method:</h3>
<u>First find XY using sine rule</u>:
Then use Pythagoras Theorem:
⇒ XY² + YZ² = XZ²
⇒ (6)² + YZ² = 12²
⇒ YZ² = 144 - 36
⇒ YZ = √108
⇒ YZ = 6√3
⇒ YZ = 10.4
Answer:
- A. Since 11 ≠ 9, there is no solution
Step-by-step explanation:
<u>Given system:</u>
- 1.75x + 1.25y = 2.75
- 7x + 5y = 9
<u>Multiply the first equation by 4:</u>
- 4(1.75)x + 4(1.25)y = 4(2.75)
- 7x + 5y = 11
We get same equation as the second one with the difference that the right side equals to 11.
Since left sides are same and right sides are different, the system has no solution.
Correct choice is A
Answer:
The rule of the translation is (x,y) -----> (x+3,y-3)
The translation is 3 units at right and 3 units down
Step-by-step explanation:
we have that
The translation of point B to point B' is
B(-6,1) -----> B'(-3,-2)
so
(x,y) -----> (x+a,y+b)
B(-6,1) ----> (-6+a,1+b)
Find the value of a
solve for a
Find the value of b
solve for b
therefore
The rule of the translation is
(x,y) -----> (x+3,y-3)
That means ----> The translation is 3 units at right and 3 units down
