Given:
A TV and Washing machine were purchased for Rs 15000 each.
Together, they are sold at Rs 35000.
To find:
The profit and profit%.
Solution:
A TV and Washing machine were purchased for Rs 15000 each. So, the total cost price is
Together, they are sold at Rs 35000. So, the selling price S.P. is 35000.
Now,
And,
Therefore, the profit is Rs. 5000 and the profit percent is 16.67%.
For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
Answer:
Part A: A
Part B: A
Step-by-step explanation:
1)
the inequality should be less than or equal to, since we need to find how many are left
now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few
thus, the answer is A
2)
A again is correct, since it represents:c ≤ 56
B represents c ≥ 56
C represents c ≤ –56
D represents c ≥ -56
32^2 +24^2 = 1600
Square root of 1600 = 40
b = 40.

<span>1. independent
2. dependent
toss a dime and then toss a quarter
* Ask yourself, "Does the 1st event have any effect on the results of the 2nd event?" And in this case, the answer is no. No matter what result happened for the dime flip, it won't affect the quarter flip. So these events are independent.
pick a card from a deck of cards keep the card and pick another one
* Ask yourself the same question. The 1st card is one of any of the 52 cards in the deck, while the 2nd card is from the remaining 51 cards. So the 1st event does affect the 2nd event. Therefore they're dependent.</span>
