The answer is 20.
4 isn't divisible by 5 and 5 isn't divisible by 4.
4 8 12 16 24 28
5 10 15 20 25
Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to.
For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.
Answer:
Step-by-step explanation:
30% of 740 = 0.30 * 740 = 222
Answer:
44°
Step-by-step explanation:
Given:
m<DOC in circle O = 44°
m<COB in circle O = 80°
Required:
Measure of arc DC.
SOLUTION:
<DOC is a central angle that intercepts arc DC. Central angles are said to be congruent to the arc they intercept.
Therefore, m<DOC = measure of arc DC.
Since m<DOC = 44°, the measure of arc DC = 44°.
Arc DC = 44°
