An Article is bought for Rs 300 and sold for 315. Find the profit and profit percent
Note Please Solve the Question Properly
Answer: PROFIT= 15
PROFIT PERCENT(%)=5%
Step-by-step explanation: As the article is bought at 300 and sold at 315, the difference between the buying and the selling prices is the profit.
Profit is the margin between the price you have bought and the price at which you have sold.
That is 315-300= 15
Now the percentage 15/300*100 = 5
To know the percentage, we have to divide the given value by the total value and after that multiply the result by 100.
Here the given value which is profit is 15 and the total is 300
After dividing 15/300 We get 0.05 and multiply by 100= 5.
So the percentage is 5%.

Answer: The profit is Rs 15 and the profit per cent is 5%.
Step-by-step explanation:
Purchase Price: Rs 300
Selling Price: Rs 315
profit: 315-300=15 ( profit=selling price -cost price)
profit percentage= (15/300)*100 ( profit percentage= (profit/cost price)*100)

a = 3; b = 7; c = 0;
Δ = b2-4ac
Δ = 72-4·3·0
Δ = 49
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
f1=−b−Δ√2af2=−b+Δ√2a
Δ−−√=49−−√=7
f1=−b−Δ√2a=−(7)−72∗3=−146=−2+1/3

they are the same shape but one is 3 .5 times larger. If you divide 42 by 3.5 you get 12 so in order to get x you need to multiply 4ft 6in by 3.5. 4ft 6in • 3.5= 15.75 ft or 15ft and 9in. Hope this helps good luck!
For dinner one night, the
family went to the local
pizza parlor. The cost of a
soda was $3. If each
member of the family
had a soda and one slice
of pizza, how much did one
slice of pizza cost?
Humans are drawn to foods that are fatty, sweet, rich and complex. Pizza has all of these components.
What is the description of pizza?Pizzeria is another word for a pizza restaurant or pizza parlor – a place where pizzas are made, sold and served to customers. The term pizzeria comes from the product, pizza, and the suffix, -eria, which translates from italian to “place of” in english. Together, pizzeria means “place of pizza”.pizza, dish of Italian origin consisting of a flattened disk of bread dough topped with some combination of olive oil, oregano, tomato, olives, mozzarella or other cheese, and many other ingredients, baked quickly—usually, in a commercial setting, using a wood-fired oven heated to a very high temperature—and served hot .If we use the variable p to represent our pizzas and s to represent our sodas, if our first equation states than 8 slices of pizza and 5 sodas cost $36.50, that's 8p + 5s = 3650.Notice that I expressed cost in terms of cents so
that we can avoid having to deal with decimals.
In our second equation, 4 slices of pizza and
10 sodas cost $37, that's 4p + 10s = 3700.
Now let's rewrite our two equations on top of one another.
8p + 5s = 3650
4p + 10s = 3700
To solve this system of equations, I would use addition.
I would multiply the bottom equation by -2
to create a situation where our p's will cancel.
When we do that, we get -8p - 20s = -7400.
Now rewrite the equations once again ~
8p + 5s = 3650
-8p - 20s = -7400
Now add the equations together.
So we have -15s = -3,750.
Divide both sides by -15 and s = 250.
Remember that I expressed cost in terms of cents so
since s = 250, it really means that a soda is $2.50.
Now just plug an s back in for the s in one equation.
When we do this, we find that p = 300.
So a pizza is $3.00

Find the equation of a parabola with its vertex at the origin and directrix x = 3.
The equation of a parabola is y²+12x=0.
In mathematics, what is a parabola?A parabola is a U-shaped plane curve in which any point is an equal distance from both a fixed point (known as the focus) and a fixed straight line (known as the directrix).
What exactly are the three parabola equations?Parabola functions are classified into three types: standard form, vertex form, and intercept form (also known as factored).
as per the given question:
We have a vertex at (0,0) and the directrix is x = 3, a line parallel to the y-axis, it must have a focus at (3,0).
The parabola equation represents the locus of a point (x, y) that moves so that its distance from x=3 and (3,0) is equal. As a result, the parabola equation is, An equation of the parabola represents the locus of a point (x, y), which moves so that its distance from x=3 and (−3,0) are equal. Hence, the equation of a parabola is
(x−(−3))² + (y−0)² = (x−3)²
or (x+3)² + y² = (x−3)²
or x² + 6x + 9 + y² = x² − 6x + 9
or y² + 12x =0
Hence, The equation of a parabola is y²+12x=0.

What is function?
A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a connection between inputs in which each input is connected to precisely one output.
A function is defined as a relation between input values and output values. The set containing input values is called domain, and the set containing output values is called range.
The most important characteristic of functions (which define them) is that an input value can't have two difference output values. Having said that, notice that sets B and D have pairs that don't follow this rule.
Therefore, the right answers are A and C, because each input value has only one output value.

The first graph shows how many of each order could fit into a bag that was hanging from a hook. First, a detailed explanation: * Let's discuss the issue's solution.
Find graph?The quantity of orders of paperclips is x, and the weight of the order of jumbo paperclips is 2 pounds. The order of paperclips weighs 2 x = 2 x, the order of packing tape weighs 3 lbs., and the quantity of orders of packing tape is y. The weight of the tape order is 3 y = 3 y, the weight of the entire order is 2 x + 3 y, and the hook can only support a maximum weight of 6 y. 2x + 3y ≤ 6
The graph that depicts this inequality, Any line's equation is y = mx + c, where m represents its slope.
The y-intercept indicates to replace x in the equation by 0; the x-intercept indicates to replace y in the equation by 0; 2x - 3y 6 is the inequality. 2x + 3y = 6 is the equation for the line.
- Subtract 2x from both sides: 3y = 6 - 2x; - Divide both sides by 3: y = 6/3 - 2/3 x; - Locate the y-intercept: x = 0; y = 2;
The line crosses the y-axis at position (0 , 2)
– Locate the x-intercept.
∵ y = 0
∴ 0 = 2 - 2/3 x
- Adjust both sides by 2/3x.
∴ 2/3 x = 2
Increase both sides by 3.
Divide all sides by 2 to get the answer.
