Answer:
The number is 2.26
Step-by-step explanation:
Let The given numbers be x
Now according to question :
x : 18 = x² - 5
I.e x = 18 × ( x² - 5 )
or, x = 18 × x² - 90
or, 18 x² - x - 90 = 0
Or, From quadratic equation , the value of x
x = 
Or, x = 
Or, x = 
So, x = 
∴ x = 
= 2.26
Hence The number is 2.26 Answer

Answer:
the cost price is 27,715
Step-by-step explanation:
Let the cost price be x
As Amab sells to Vivek at 15% profit
So the selling price be
= 115 ÷ 100 × x = 1.15x
And Vivek sells to sagar at a profit of 10%
= 1.15x × 110 ÷ 100
= 1.265x
Now sagar pays it for 35,060
So , the cost price be
1.265x = 35,060
x = 27,715
Hence, the cost price is 27,715
Answer:
x = 71.937 ft or 72 ft
Perimeter = 187 ft
Area of triangle = 1260 ft²
Step-by-step explanation:
Pythagorean Theorem
a^2 + b^2 = c^2
a = 35
b = x
c = 80
35^2 + x^2 = 80^2
x^2 = 5175
x = 71.937 ft or about 72 ft
Perimeter = a + b + c = 35 + 72 + 80 = 187 ft
Area of triangle =1/2*base*height= 1/2(72)(35) = 1260ft^2
