50,779/590 is 90.7125 but rounded to 90.71
the answer is 20
1/10 of 200 is 200* 1/10 = 200/10 which is 20
For each increment in x, the output is multiplied by 2. The function could be written the way a geometric sequence can be written:
... f(x) = 5·2^(x-1)
Or, it could be simplified to ...
... f(x) = (5/2)·2^x
The first 5 terms will be
... 5, 10, 20, 40, 80
Answer:
x = 40
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left and calculate the third angle
Subtract the sum of the 2 angles from 180
third angle = 180° - (75 + 50)° = 180° - 125° = 55°
Consider the triangle on the right
The third angle = 55° ( vertical angles )
Subtract the sum of the 2 angles from 180
x = 180 - (55 + 85) = 180 - 140 = 40
