About seven inches. Pretty sure
Answer:
y = 
Step-by-step explanation:
to get the hypotenuse:
use the Pythagorean theorem:
a² + b² = c²

plugin values:
19² + 8.2² = y²
y = 
Answer:
See below
Step-by-step explanation:
x = part 1
3x = part 2
x + 3x = part 3 summed, they equal 1000
x + 3x + x + 3x = 1000
8x = 1000
<u>x = 125 3x = 385 third part = 500 </u>
Answer:
30 questions
Step-by-step explanation:
