1. 326.73 Its easy, just get the circumference of the circle and multiply it by 9. Then get the area of the circle and multiply that by 2, then add the values together. Cant do 2 or 3 cause I feel like I will get them wrong since I start overthinking it.
120
OA = OB
angle OAN = 90 degrees, so OAB and OBA is both 30 degrees.
Answer:
x = -2
Step-by-step explanation:
The segments described in the question are equidistant (meaning they are the same length). Therefore, using algebraic techniques, we can set these two equal to each other and solve for x.
4x - 8 = 6x - 4 Combine like terms by subtracting 6x from both sides.
-2x - 8 = -4 Combine like terms by adding 8 to both sides.
-2x = 4 Divide by -2 on both sides of the equation.
x = -2
20) 13=2f+5
2f=8
f=4
6x<=3
x<=1/2
-f-5(2f-3)=-f-10f+15=-11f+15
answer B
45+0,15*45=45+6,75=51,75$
5 3/8 rounds to 5,
4 7/10 rounds to 5
Your estimated sum is 10
