Answer:
Step-by-step explanation:
<u>Find the measure of arc BD</u>
- m∠A = 1/2(arc BC - arc BD)
- 2*36° = 150° - arc BD
- arc BD = 150° - 72° = 78°
<u>Find the measure of arc DC</u>
- arc BD + arc BC + arc DC = 360°
- arc DC = 360° - (150° + 78°) = 360° - 228° = 132°
Correct choice is B
6.5 times 4 and 13 times 2
It will take 40 minutes.
To solve, divide 60 by 3. 60 is how many minutes there are in a minute. 3 is how long it takes to paint 2/5 of the room. We do not need to use the number 2/5 in this situation. Now back to 60 divided by 3. The answer is 20 minutes. Now multiply 20 by 2 to get 2/3 of an hour. Therefore, it takes 40 minutes to paint 2/5 of a room.
A bar graph since I'm only going up by fives it's easy to show as a bar graph
5/2c - 3 = 3/7c + 4...subtract 3/7c from both sides
5/2c - 3/7c - 3 = 4.....add 3 to both sides
5/2c - 3/7c = 4 + 3....common denominator of 7 and 2 is 14
35/14c - 6/14c = 7...simplify
29/14c = 7....multiply both sides by 14/29, eliminating the 29/14 on left
c = 7 * 14/29
c = 98/29 = 3 11/29
