Answer:
-15
Step-by-step explanation:
1/-13
The reciprocal is

Because of the law of indices,
We'll have 
= -13.
-1/2
The reciprocal is
1 ÷ -1/2
Because of the law of indices,
We'll have 
= -2
Therefore, the sum would be -13 + (-2) which would be equals to -15.
Answer:
The area is π= 3.14 approx
Hope it helps!
Step-by-step explanation:
Area of circle = πr^2
Radius= r = 1 unit
So area,
= 3.14*(r)^2
= 3.14*(1)^2
= 3.14*1
= 3.14 or π if you want the specific answer
Answer:
x = 30.
Step-by-step explanation:
For the triangles to be similar corresponding sides must be in the same ratio.
So 50/ 75 = x / 45
75x = 50*45
x = 50* 45/75
= 2 * 45 / 3
= 30. (answer).
