Answer:
84 feet
Step-by-step explanation:
If the perimeter is 36 feet, and all the sides are the same length, then all the sides are 9. if we increase the length by 3 feet and decrease the width by 2 feet then we are left with 12 * 7 = 84
Answer:
3/4
Step-by-step explanation:
To answer this question we must first calculate the area of GHJK:
- A= GH*HJ
- A= (LM/2)* (MN/2)
- A= LM*MN/4
- LM/MN is the area of LMNO
- So the area of LMNO is 4 times the area of GHJK
- A is the area of LMNO and S the area of GHJK
- S= A/4
- A-S= A-A/4 = 3A/4
- so the area that is not shaded is 3/4
Its the last choice there. Converting that to degrees you get the interval of 90<O<120, which is the only angle that lies in the quadrant in which cosine is negative, which is the second quadrant. Cosine is also negative in the third quadrant, but you don't have choices for the third quadrant.
Answer:
Random sample
Step-by-step explanation:
It's a random sample because she did not pick the students 1 by 1, she just chose random students from a list
