Answer:
Mr Ronaldo paid $4,932 in income tax
Step-by-step explanation:
In this question, we are asked to calculate the amount Mr Ronaldo pays in income tax
To calculate this, we need to calculate 9% of his annual earnings
His income tax = 9/100 * 54,800
Income tax = $4,932
I think the scale of the factor of area is 2
Answer:
52
Step-by-step explanation:
plug in 3 if we're going by 0,1,2,3
2+ (3-1)25
2+50
52
The picture is difficult to read, but it looks like
∠ADB = 2x²
∠ACB = 10x
These two angles have equal measure, so you have
2x² = 10x
2x(x -5) = 0 . . . . . subtract 10x and factor
x = 0, or x = 5
The measure of arc AB is twice the measure of either inscribed angle, so would be
arc AB = 2×10x
= 2×10×5
= 100 . . . . . degrees
Arc AB is 100°.
Answer:
The values of 
and 
so that the two linear equations have infinite solutions are 
and 
, respectively.
Step-by-step explanation:
Two linear equations with two variables have infinite solution if and only if they are<em> linearly dependent</em>. That is, one linear equation is a multiple of the other one. Let be the following system of linear equations:
(1)
(2)
The following condition must be observed:
(3)
After some quick operations, we find the following information:
, 
, 
The values of and so that the two linear equations have infinite solutions are and , respectively.
