{y|1 > y}, (-∞, 1); you did not specifically mention what notation you needed, so I wrote both [Internal Notation and Set Notation].
Answer:
1350 ft²
Step-by-step explanation:
First off, I notice that the triangle at the bottom can fit the slant at the top to make a perfect rectangle.
This will leave us with a rectangle. We can add up 4 and 5 for the sum of 9, making one side 9 inches.
5 + 4 = 9 in
We multiply 9 by 3 to get the actual length of that side
9 x 3 = 27 ft.
We multiply 16 and two-thirds by 3 to get the actual length of the other side
x 3 = 50 ft.
To find the area of this rectangle we multiply length and width
50 x 27 = 1350 ft²
3 rooms
1 1/4x3=3 3/4
or...
3 3/4 divided by 1 1/4 = 3
there is no underlne here
so if the underlined number is 2 then your answer would be 0.7
if the underline is 4 it would be 0.7
theres a rhyme that helps "four or less let it rest. 5 or more give it a score"
meaning if the number is under 4 dont change if its over 5 then change
