If €1 is with £0.89, and £1.00 is worth ¥48, what is ¥256 in €?
anastassius [24]
I don't know where to find those number on my keyboard so I will subsitute
€=x£=y¥=zso
1x=0.89y
and 1y=48z

first find conversion factor from z to x

1x=0.89y
y=48z
subsitute 48z for y in first equation
x=0.89(48z)
x=42.72z
divide both sides by 42.72
x/42.72=z

256z is wanted so
multiply both sides by 256
x/1 times 256/42.72=256z
5.99251x=256z

there are aprox 5.99x in 256z or about 6

Please help! Attached is the picture of the problem! Will name Brainliest!
Degger [83]

<u>Answer:</u>

Blank 1: Parallel

Blank 2: Zero

Blank 3: Perpendicular

Blank4: Maximum

<u>Step-by-step explanation:</u>

If you really ready it out loud with these words in the blanks as I assigned them, it sounds completely right.

<u>Further Explanation:</u>

Blank 1: If the sentence if talking about the angle being of 0 degrees, it means that the line on a graph would be completely straight across;

Blank 2: Since it's a straight line across, it would have little to no work to do in order to force anything.

Blank 3: With this one being a 90 degree angle, and not being a straight line it would only be natural that this answer would be perpendicular.

Blank 4: It would have a lot of work to do since the said line is pushing in two separate directions, as you can see from the picture provided in the question.

Hope this helped!

If it's incorrect I apologize.
