Answer:
m∠AOC= 120°
, m∠BOD = 130°
m∠COE = 110°
m∠COD.= 60°
Step-by-step explanation:
Let's note that
AOF = COD= 60°
BOC = FOE= 70°
AOB = DOE= 50°
Given: m∠AOB=50°, m∠FOE=70°. m∠AOC
, m∠BOD,
m∠COE
m∠COD. = AOF = (360-(2(70)+2(50)))/2
AOF = (360-240)/2
AOF = 120/2
AOF = 60°= COD
COE = COD+DOE= 60+50= 110°
BOD = BOC + COD = 70+60= 130°
AOC = AOB + BOC = 50+70 = 120°
Answer: $16, 666.67
<u>Step-by-step explanation:</u>
Job 1: 0.06x
Job 2: 0.03x + 500
0.06x > 0.03x + 500
<u>-0.03x </u> <u>-0.03x </u>
0.03x > 500
<u>÷0.03</u> <u> ÷0.03 </u>
x > 16,666.67 <em>rounded to the nearest penny</em>
2x - 11
-9 + x
equate the equations
2x - 11 = -9 + x
bring like terms to one side
2x - 11 = -9 + x
- x +11 +11 - x
-11 and +11 cancels out
+x and -x cancels out
2x - x = 11 - 9
x = 2
Answer:
a) If the diameter is 400 feet wide, then the radius is half that, which is 200 feet wide.
b) The circumfernce is π times the diameter, which is 400 feet. 400×π≈1256.64
c) She is not correct. She squared 400, which is 160000, when she should have squared 200, which is 40000. Then, multiply by π.
40000 × π ≈ 125663.7
Answer: 25 inches
Step-by-step explanation:
Let's imagine that this line is the leg A______________B________C
x 11
|___________36____________|
From A to C = 36 inches
From B to C = 11 inches
To find A to B all we have to do is subtract the knee to ankle length (11) from total leg length (36), which 36 - 11 = 25 inches.
