Answer:
Step-by-step explanation:
3 times 4 is 12. you can solve this by dividing 12 by 3, or by skip counting and using repeated addition.
Answer:
<h3>
m∠BAC = 80° </h3>
Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°
Break this problem down first. You have two lines each with length of 5. You also have two halves of a circle, combine them to get a full circle with a radius of 2. The formula to find the perimeter of a circle is

and this gives a perimeter of 12.566 for the circle. Add this to your sides and you get a total of 22.566 which is answer B
the probability is 5/15 or 1/3.
You add up all the coins (5+10=15) and since there’s 5 blue coins in the bag, you put 5 over 15. You simplify that to 1/3.
hope this helped !!
