The square root of 100 is 10. Which is a whole number and whole numbers are rational numbers.
Perimeter = 2 ( width + length)
294 = 2 (56 + length)
294/2 = 56 + length
147 = 56 + length
147 - 56 = length
91 = length
so the length is 91 feet
Answer:
3 30 page printers, 10 70 page printers
Step-by-step explanation:
x + y = 13
40x+70y = 820
Solving for y in first equation gives: y = 13 - x
Plug into second equation: 40x + 70(13 - x) = 820
40x + 910 - 70x = 820
-30 x = -90
x = 3
Plug into original equation: 3 + y = 13
y must = 10.
So, the company owns 3 thirty page presses, and 10 70 page presses,
This is true. IDK if there is a question behind it.
