Answer:
x = 
Step-by-step explanation:
given, 50 - x^2 = 0
add x^2 to both sides, 50 = x^2
square root both sides,
= 
simplify, 50 / 5 = 10 / 5 = 2
you have a pair of 5's, and a 2,
= x

Given that , a dealer bought an article for Rs 1500 and sold it at a profit of 20% .
So , here ,
- Cost price of the article = Rs 1500.
- Profit on the article = 20% .
Since the article is sold at profit , the Selling price of the article will equal to Cost price + 20% of cost price .
Firstly let's Calculate 20% of 1500 .
= 20% of Rs 1500 .
= 20/100 × Rs 1500 .
= Rs 300 .
Hence we can find now Selling price as ,

⇒ SP = CP + Profit .
⇒ SP = Rs ( 1500 + 300 ).
⇒ SP = Rs 1800 .
<u>Hence </u><u>the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>Rs</u><u> </u><u>1</u><u>8</u><u>0</u><u>0</u><u>.</u>
Answer:
w=12
l=20
Step-by-step explanation:
The area can be found using the following equation:

Given the information provided, we are also told the following:

Therefore, we can plug in our length and our area:

We can solve by using the quadratic formula.

w=12, so w+8=20.
Answer: $3.75 + $0.15n ≤ $5.25
Step-by-step explanation:
$3.75 is the cost of the sandwich
$0.15 is the cost for each additional topping
$5.25 is the maximum amount you can spend
Ask yourself, how many additional toppings can you add before going over the total of $5.25. Since we don't know this value, it's a variable, n.
Answer:
Slope = 0.5
Step-by-step explanation:
The two points are: (2, 1) and (0, 0)
Slope = (1 - 0) / (2 - 0) = 0.5
Slope = 0.5
