Minor Arc AC = 110 degrees (given)
As indicated in the hints,
OA=OC => OAC=OCA=(180-110)/2 = 35
Similarly,
OAB=OBA=(48-35)=13
=>
OBC=OCB=(180-35-35-13-13)/2=(180-96)/2=84/2=42
=>
Angle B = 13+42 = 55 degrees
Check:
55+55+35+35+13+13 = 180 degrees (angles of a triangle) ok.
Answer:
No
Step-by-step explanation:
2X + 12=13x - 2x + 5
2X + 12= 11x+5
2x-11x = 5-12
-9x = -7
X = 7/9
so the answer is NO
B and C. This problem comes down to equal fractions, so B is 2/3 and C is 1/1.5. And 2/3=1/1.5. So they are correct
Answer:
10
Step-by-step explanation:
2/3 can be multiplied by 5 to equal 15ths since we can know 15 (seconds number fraction) is 5 times the originals (first numbers fractions)
This equals to 10/15 and means that with 1/15th on each 10 sandwiches can be made.
The answer gives it straight forward but explanation gets in depth
Edit: I saw your answer and yes it equals 10 but you multiply what it is a fraction of too.
2/3
x5
10/15
Hope that helps some more
Answer:
21minutes
Step-by-step explanation:
its 21 minutes because 5x3=15 so 7x3=21
