Let x represents the amount of a transaction and let f(x) represents the amount Isabel is charged for the transaction write a fu

Svetradugi [14.3K]

Answer:

$f(x) = \frac{Px}{100}$

Step-by-step explanation:

Let P% of the transaction amount is charged in the account.

So, if the transaction amount is x, then the charge for that transaction will be

$\frac{ Px }{ 100 }$ .

Therefore, if f(x) represents the amount Isabel is charged for the transaction then we can write $f(x) = \frac{ Px }{ 100 }$ , where P% is the rate of charge. ( Answer )

At a local Brownsville play production, 560 tickets were sold. The ticket prices varied on the seating arrangements and cost $8,

BigorU [14]

Answer:

Number of $8 tickets sold = 210

Number of $10 tickets sold = 280

Number of $12 tickets sold = 70

Step-by-step explanation:

The number of ticket sold is 560 tickets .

Total number of ticket sold = 560 tickets

The prices varies as $8, $10 and $12.

The total income from the ticket sold = $5320

Let

number of $8 ticket sold = a

number of $10 ticket sold = b

number of $12 ticket sold = c

a + b = 7c

Therefore,

8a + 10b + 12c = 5320

a + b + c = 560

7c + c = 560

8c = 560

divide both sides by 8

c = 560/8

c = 70

Insert the value of c in the equations below

8a + 10b + 12c = 5320

8a + 10b + 12(70) = 5320

8a + 10b + 840 = 5320

8a + 10b = 5320 - 840

8a + 10b = 4480...........(i)

a + b + c = 560

a + b + 70 = 560

a + b = 560 - 70

a + b = 490...............(ii)

8a + 10b = 4480...........(i)

a + b = 490...............(ii)

a = 490 - b

insert the value of a in equation(i)

8(490 - b) + 10b = 4480

3920 - 8b + 10b = 4480

3920 + 2b = 4480

2b = 4480 - 3920

2b = 560

b = 560/2

b = 280

insert the value of b in equation (ii)

a + b = 490...............(ii)

a + 280 = 490

a = 490 - 280

a = 210

Number of $8 tickets sold = 210

Number of $10 tickets sold = 280

Number of $12 tickets sold = 70

Is 831 divisible by 3?? Yes or no

mixer [17]

yes 831 is divisible by 3

One way I know this is because when adding all the digits in the number you get 12 which is divisible by 3

Also if you do divide 831 ÷ 3 it would equal 277

Find the area of the shaded portion of the figure. Each vertex of square ABCD is at the center of a circle. Round your answer to

IrinaK [193]

Given:

Each circle has a diameter of 2 inches each.

The outer square has a side length of 4 inches and the square ABCD has a side length of 2 inches.

To find:

The area of the shaded region.

Solution:

Each circle has a diameter of 2 inches. The square ABCD is at the center of each circle so it has a side length of 1 inch.

To determine the area of the shaded region, we subtract the area of the quarter-circles in the square ABCD from the area of the square ABCD.

The area of a quarter-circle $=\frac{\pi r^{2} }{4} .$

All the quarter-circles have a radius of 1 inch.

The area of 1 quarter-circle $=\frac{\pi r^{2} }{4} = \frac{\pi (1^{2}) }{4} = \frac{3.1415}{4} .$

The area of 4 quarter-circles $=4(\frac{3.1415}{4}) = 3.1415.$

So the area of the quarter-circles in the square ABCD is 3.1514 square inches.

The area of a square $= a^{2} .$

The area of square ABCD $=2^{2} =4.$

The area of the shaded region $=4-3.1415=0.8585.$

The area of the shaded region is 0.8585 square inches.
