Answer:
diagonal is 17 cm
Step-by-step explanation:
use pathagorean theorem
you have a = 8, b= 15
c is the diagonal of the rectangle (rectangle has 90deg angles)
c^2 = a^2 + b^2
c^2 = 8^2 + 15^2
c^2 = 64 + 225
c^2 = 289
take square root
c = 17

So, 6 feet is equal to 72 inches. You need 18 inches for one bracelet, so by dividing 72/18, you get 4. So, he can make 4 bracelets.
I = -425x^2 + 45,500(x) - 650,000
x = 40
I = -425(40^2) + 45,500(40) - 650,000
I = -425(1600) + 1,820,000 - 650,000
I = -680,000 + 1,820,000 - 650,000
I = 1,820,000 - 1,330,000
I = 490,000 <===
