Answer:
1. True
2. True
3. y = -1
4. False
Step-by-step explanation:
1 -------------------------
sin(-90) = -1
sin(270) = -1
True
2 --------------------------
y = cos(-90)
y = 0
True
3 -------------------------
y = tan(-45)
y = -1
-1
4 ---------------------------
tan(90) cannot be calculated
False
Answer: 48
Step-by-step explanation:
Given
Trapezoid DEFG is dilated by a scale factor of

Suppose the length of EF is 
Multiply the side length of DEFG by
to form E'F'


The room is 18 ft by 26 ft which is 468 ft^2
She can afford a 240 ft^2 rug
12 * 20 = 240
She can afford a rug that is 12 ft wide by 20 ft long
X - 25 = 1/3x + 105
x - 1/3x = 105 + 25
2/3x = 130
x = 130 * 3/2
x = 390/2
x = 195 <==== previous weight
