Answer:
After using the offer the carpet would cost Ahmed $180.
Step-by-step explanation:
Given:
Cost of the carpet = $240
Discount percent = 25%
We need to find the cost of the carpet after discount.
Solution:
First we will find the Discount cost.
Now we know that;
Discount cost is equal to Discount percent multiplied by Cost of the carpet divided by 100.
framing in equation form we get;
Discount cost = 
Now we will find the Cost of the carpet after discount.
Now we know that;
Cost of the carpet after discount is equal to Cost of the carpet minus Discount cost.
framing in equation form we get;
Cost of the carpet after discount = 
Hence After using the offer the carpet would cost Ahmed $180.
How you do this is you go from left to right with each one, and figure out which number is greater. For this particular problem the answer will be,
1.2 1.23 2.31 3.2
Answer:
Step-by-step explanation:
A) identical triangles PSR and PSQ
B) in the given triangle PQR angle P is 90 degrees and PS is perpendicular on QR. so the angle PSR and angle PSQ is 90 degrees also angles RPS , SPQ are 45 degrees . hence when two angles of a triangle are 90 and 45 degrees. the third is also 45 degrees. when the three angles of two triangles are equal they are said to be similar
C) the triangle PSR is a isosceles triangle therfore the two sides of the two oposite equal angles must be equal. if RS=4 then SP=4 as well the sides opposite to 45 degrees angles. the third side can be found by using the formula
c²=a²+b²
c²=4²+4²=16+16=32
c=√32=√16*2=4√2
