This figure is 14 of a circle.
Wittaler [7]

Answer:

The perimeter of a quarter of a circle with radius 2 inches is 7.1 inches.

Step-by-step explanation:

Given : A quarter of a circle with radius labeled 2 in.

Quarter of circle means fourth part of a circle  (as shown in image by shaded part).

We have to find the perimeter of this shaded quarter of circle.

Perimeter is the sum of the dimension of the given figure.

Perimeter of circle is 2\pi r

Since, we are given Quarter circle so its perimeter \frac{2}{4} \pi r+r+r=\frac{1}{2} \pi r+r+r

Perimeter of given figure = \frac{1}{2} \pi r+r+r

Perimeter of given figure = \frac{1}{2}\cdot 3.14 \cdot 2+2+2=3.14+4=7.14

Thus, the perimeter of a quarter of a circle with radius 2 inches is 7.1 inches.

F) The marked price of a radio is 25 % above the selling price and the cost pr
Ostrovityanka [42]

Answer:

See explanation below.

Step-by-step explanation:

Let's say, x represents the sale price of radio.

Then the marked price of the radio is 1.25x

The cost price of the radio is (1.25x)(0.70)

The discount is simply 25% because the radio is being sold at 25% less then the marked price.

The gain percent is given as:

\frac{x-1.25x\times \:0.70}{x}\times 100\\\\=12.5\%

The radio is being sold at 12.5% gain.

Best Regards!

The cost see for manufacturing X units of a certain product is given by C equals X squared -10 X +35 find the number of units ma
Marianna [84]

9514 1404 393

Answer:

  110 units

Step-by-step explanation:

Fill in the given value and solve for x.

  c = x^2 -10x +35

  11035 = x^2 -10x +35

  11025 = x^2 -10x +25 = (x -5)^2 . . . . subtract 10 to complete the square

  x = 5 +√11025 = 5 +105 . . . . find the positive solution

  x = 110

The number of units manufactured at a cost of 11,035 is 110 units.
