Use the Pythagorean theorem to find z:
z = √(6^2 + 9^2)
z= √(36 + 81)
z = √117
z = 3√13 = 10.8
Use leg rule to find x:
x/6 = 6/9
Cross multiply:
9x = 36
Divide both sides by 9:
x = 36/9
x = 4
Use Pythagorean theorem to find y:
y = √(6^2 + 4^2)
y= √(36 + 16)
y = √52
y = 2√13 = 7.2
Answer:
47,643
Step-by-step explanation:
This question is basically asking you to add up all of these numbers together and present the end result.
1) 40,000 + 7,000 = 47,000
2) 600 + 40 + 3 = 643
3) 47,000 + 643 = 47,643.
The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
Density = m/v
3.86kg=3860g
d= 3860/200
= 19.3g/cm^3
therefore it is gold.
I think #13 is A (90 cubic meters) even though you already have that
