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 width of a rectangle measures (2.5u+9.8)(2.5u+9.8) centimeters, and its length measures (1.5u+3.9)(1.5u+3.9) centimeters. Wh

icang [17]

Solution,

We have,

Width of rectangle, b = (2.5u+9.8) cm

Length of rectangle, l = (1.5u+3.9) cm

We need to find the expression for the perimeter of the rectangle. The formula for the perimeter of a rectangle is given by:

Perimeter = 2(l+b)

P = 2[(2.5u+9.8)+(1.5u+3.9)]

Collecting like terms

P = 2[(2.5u+1.5u)+(9.8+3.9)]

P=2(4u+13.7)

⇒ P = 8u+27.4

So, the expression for the perimeter of the rectangle is (8u+27.4) cm.

Find the Quetion of the line that passes through the points (1,6) and (5,2)

NemiM [27]

Answer:

$y=-x+7$

Step-by-step explanation:

Equation of straight line is given as

$y-y_1=m(x-x_1)$

where slope m is calculated as

$m=\frac{y_2-y_1}{x_2-x_1}$

Here 

$(x_1, y_1)=(1, 6) \ \ and \ \ (x_21, y_2) = (5, 2)$

$m = \frac{2 - 6}{5 - 1}\\m=\frac{- 4}{4} \\m=-1$

Equation of line that passes through the points (1,6) and (5,2)

$y-6=-1(x-1)\\y=-x+7$
