At a profit of 8% a shopkeeper sold a calculator for Rs 1382.40.If he wants to increase his profit by 2%, at what price should h
MAVERICK [17]

Answer: New Price = Rs. 1408

Step-by-step explanation: Selling Price = Rs 1,382.4

Profit = 8%

Increased Profit = 10% (we'll discuss that later)

Costing Price:

Let CP be x

x = 1382.4 - 0.08x

=> x+0.08x = 1382.4

=> 1.08 x = 1382.4

Dividing both sides by 1.08

=> x = Rs 1280

So, the cost price is Rs 1280

Now, Let's discuss about the increased Profit:

Profit %age = 10%

Profit =  Profit %age * CP / 100

Profit = 12800/100

Profit = Rs. 128

New Price:

New Price = CP + Profit

New Price = 1280+128

New Price = Rs. 1408

Which of the following are continuous functions? (Select all that apply.) The temperature at a specific location as a function o
castortr0y [4]

Answer with Step-by-step explanation:

A continuous function is a function that is defined for all the values in it's domain without any sudden jumps in the values in the domain of the function. All the given situations are analysed below:

1) The temperature at la location as a function of time is continuous function since at any location the temperature is defined for all the time and the temperature cannot suddenly change from say 10 degrees Celsius to 100 degrees Celsius instantly without passing through intermediate values.

2) The temperature at a specific time as a function of the distance due west from New York city is a continuous function as temperature is defined for all the instants of time without any sudden changes as we move between places.

3) The altitude as an function of distance due west from New York is a discontinuous function as there may be sudden changes in the altitude due to changes in topography such as presence of cliff or valley.

4) The cost as a function of function of distance traveled is a discontinuous function since the cost of travel increases integrally in increments of distance and not in a continuous manner.

5) The current in a circuit as function of time is discontinuous function as the current jumps instantly from 0 to a non zero value when we switch on the circuit and same is true when we switch off the circuit it's value decreases instantly to 0.

If an initial investment of $2000 is compounded continuously at a rate of 19.3%,
Mekhanik [1.2K]
So the equation should be 2000(1.193)^11. Just plug that into your calculator. The way I got 1.193 is because the percentage can be converted to decimal by moving the dot two points to the left. The formula is cost(1+percentage)^years. The Answer should be about 13933.97.

You roll a six-sided die one time. After that, you spin a spinner that is equally divided into 6 parts. 2 parts are red, 1 part
Tanzania [10]

Answer:

<h2>5/36</h2>

Step-by-step explanation:

This is a probability problem, so let us treat it as such.

the sample space for the die is =(1,2,3,4,5,6)

the sample size is =6

For the spinner the sample space is

red=2

pink=1

white=3

the sample size for the spinner is =6

The probability of rolling a number greater than 1 and then the spinner stopping at a pink section

=Pr(no>1)*Pr(spinner=pink)

no>1= 2,3,4,5,6

no>1=5

pink=1

hence

=5/6*1/6

=5/36

<h2>The probability is 5/36</h2>
