Answer:
1
Step-by-step explanation:
Assuming, we want to find the value of 
Recall that: any non-zero number exponent zero is 1.
Using this property, we simplify our expression to
since 
Now using the property of exponents: 
This implies that:
The correct answer is 1
I think it might be c or A
Answer:
(look in the the Step by step)
Step-by-step explanation:
When the diagonals of a quadrilateral are perpendicular, the area of that quadrilateral is half the product of their lengths.
.. A = (1/2)*d₁*d₂
Substituting the given information, this becomes
.. 58 in² = (1/2)*(14.5 in)*d₂
.. 2*58/14.5 in = d₂ = 8 in
The length of diagonal BD is 8 in.
310 - 220 = 90
90/310 = x/100 (cross multiplication)
9000 = 310x
9000/310 = x
x = around 29%
