Answer:
25
Step-by-step explanation:
12/x = 48/100
48/100 = 0.48
12 = 0.48x
12/0.48 = 25
The line in the middle has a right angle, so the angle just above the Y would be 90 degrees.
The angle to the right of y is given as 48.
The three inside angles of a triangle need to equal 180.
So y = 180 - 90 - 48 = 42 degrees.
5y-10 and 2y-6 unless the two are together in which case are they being added or multiplied (the equations).
Not an expertise on infinite sums but the most straightforward explanation is that infinity isn't a number.
Let's see if there are anything we missed:
∞
Σ 2^n=1+2+4+8+16+...
n=0
We multiply (2-1) on both sides:
∞
(2-1) Σ 2^n=(2-1)1+2+4+8+16+...
n=0
And we expand;
∞
Σ 2^n=(2+4+8+16+32+...)-(1+2+4+8+16+...)
n=0
But now, imagine that the expression 1+2+4+8+16+... have the last term of 2^n, where n is infinity, then the expression of 2+4+8+16+32+... must have the last term of 2(2^n), then if we cancel out the term, we are still missing one more term to write:
∞
Σ 2^n=-1+2(2^n)
n=0
If n is infinity, then 2^n must also be infinity. So technically, this goes back to infinity.
Although we set a finite term for both expressions, the further we list the terms, they will sooner or later approach infinity.
Yep, this shows how weird the infinity sign is.
