Answer is 120
Use the Pythagorean theorem to find the distance from the center to the side, 6.5²-(5/2)²=6², so the distance is 6. The perimeter is 5×8=40 then use ½(6)(40)=120

It would be 120 if you use 5 but if you use 6.5 it would be 204.

I hope this helps:)

Answer: Rs. 100

Step-by-step explanation:

Given the following :

Total expenditure for dance show = Rs. 25000

Profit made except expenditure = Rs. 12,000

Number of people who observed and paid for the show = 370

Amount paid per person will be :

(Total amount or revenue realized / number of observers who paid)

Total revenue realized = (total expenditure + profit made)

Total Revenue realized = Rs.(25,000 + 12,000) = Rs. 37,000

Amount paid per observer = (Rs. 37,000 / 370)

= Rs. 100

If the longest side of a right triangle is 3x-4, the shortest side is x and the other side is 2x+4, find the lengths of the side

enyata [817]

Answer:

$Solution,\\Let~h=3x-4~,p=x~and~b=2x+4\\Then,\\h^{2} = p^{2}+b^{2}\\or, (3x-4)^{2}=x^{2}+(2x+4)^{2}\\or, 9x^{2} - 2(3x)(4) +16 = x^{2} +4x^{2}+2(4x)(4)+16\\or, 9x^{2} -24x+16 = 5x^{2}+16x+16\\or, 9x^{2}-5x^{2}-24x-16x=0\\or, 4x^2-40x = 0\\or, 4x(x-10) = 0\\i.e. x = 0~or~x=10\\$
