A trader sold a radio set for 72.00 making a profit of 8% .Find , correct to the nearest ghana cedis ,the cost price for the rad
VMariaS [17]

Given:

The selling price of a ratio set = 72.00

Profit percent = 8%

To find:

The cost price for the radio set.

Solution:

Let x be the cost price for the radio set.

Radio set is sold at 8% profit.

\text{Selling price}=x+\dfrac{8}{100}x

\text{Selling price}=x+0.08x

\text{Selling price}=1.08x

The selling price of a ratio set is 72.00.

72=1.08x

\dfrac{72}{1.08}=x

x=66.666...

x\approx 67

Therefore, the cost price for the radio set is 67.

Is 33,44,55 a right triangle?
Paul [167]

Answer:

Yes!

Step-by-step explanation:

We know that right triangles follow the Pythagorean Theorem, where

a^{2} + b^{2} = c^{2}

So we will put our side lengths into this formula, keeping in mind that c = the hypotenuse, which is the longest side. a and b are fairly arbitrary.

33^{2} + 44^{2} = 55^{2}

If this works, we know it's a right triangle.

1089 + 1936 = 3025

3025 = 3025

It worked! It's a right triangle!!
