The reciprocal of -1/3 is -3/1
and the reciprocal of 4/1 is 1/4
Answer:
<h2>Yes. It's a right triangle.</h2>
Step-by-step explanation:
If a ≤ b < c are the length of the sides of a right triangle, then
a² + b² = c².
We have:
a =30 ft, b = 40 ft and c = 50 ft.
Check the equality:
L = 30² + 40² = 900 + 1600 = 2500
R = 50² = 2500
L = R
Answer:
its obviously the property of zero as an exponent
Step-by-step explanation:
Answer:
162 and 
Step-by-step explanation:
To find the original number multiply by the reciprocal of the multiplier, that is
90 ×
=
= 162

Similarly
Change the mixed number into an improper fraction
5
=
, then
×
( cancel 35 and 7 by 7 / cancel 6 and 3 by 3 )
=
