Answer:
X =
, Y = 3 , Z = 10
Step-by-step explanation:
using Pythagoras' identity in all 3 right triangles
X² = 1² + 1² = 1 + 1 = 2 ( take square root of both sides )
X = 
middle triangle
Y² = 1² + X² = 1 + (
)² = 1 + 2 = 3
triangle on right
Z² = 1² + Y² = 1 + 3² = 1 + 9 = 10
Answer:
225.75
Step-by-step explanation:
Before Tax Price: $210.00
Sale Tax: 7.50% or $15.75
After Tax Price: $225.75
If you divide the first equation by 2 and the second by 3, you get

These equations differ only in their y-intercept, so describe parallel lines. The appropriate choice is ...
... H The lines are parallel.
Answer:
3.5
Step-by-step explanation:
in order to find the maximum, we are basically solving to find the vertex of the graph. to find the vertex use :
-b/2a
the 'b' is 112
the 'a' is -16
so :
-112/-32 = 3.5
