Answer:
0.5
Step-by-step explanation:
3x10^5
+7x10^4
+7x10^3
+0x10^2
+6x10^1
+0x10^0
The two numbers are 41 & 37.
The way to solve this is by setting up an equation. We know that 2 numbers are going to equal 78, so here would be the general equation (let x represent the number we don't know):
(x) + (x + 4) = 78
Now, we need to simplify it (combine like terms):
2x + 4 = 78
Then you can solve it like any other equation. Subtract 4 on both sides:
2x = 74
Divide by 2 on both sides:
x = 37.
So, now you know one number is equal to 37 and that the other is 37 + 4.
That's how you get 37 & 41.
The answer would be the Blue sector.
Because 15% of 360° is 37.2
37.2 is only 2.8 away from 40 making it the closest!
Independent is independent, it isn't influenced by anything
dependent vairable is dependent on the independent variable
example
y=3x
x is independent
y changes because x changes
3y=x
y is now independent
