Answer:
1/100
Step-by-step explanation:
the problem description is not copied fully.
but I think I understand it.
since the ratio of the perimeter is 1/10, so is then also the ratio for each side.
that means the longest side of ABC is 4 units (40/10), right ?
anyway, when the ratio of lengths and distance is 1/10, then the ratio for the area is 1/10×1/10 = 1/100.
because for the area (baseline × height / 2) two lengths have to be multiplied. and that multiplies the scaling factor twice into the calculation effectively squaring it as the area scaling factor.
and 1/10×1/10 = (1/10)² = 1/100
The definition of math is the overall group of sciences that study numbers, shapes and their relationships. An example of math is arithmetic, the study of addition, subtraction, multiplication and division. ... (uncountable, North America) Arithmetic calculations; (see do the math).
Use the point-slope form of the equation:-
y - y1 = m(x - x1) where m=slope and (x1,y1) is a point on the line
Here we have
y - 5 = -1/2(x - (-5))
y - 5 = -1/2(x + 5)
y = -1/2x - 5/2 + 5
y = -1/2x + 5/2
this can also be written as
2y = -x + 5
or in standard form it is x + 2y = 5
