Does anyone else here know the answer?:(
Answer:
Hi there, your answers here are 44% and 33%.
To convert 4/9 to a percent, first we can write it as a decimal - 0.44444444444. To get this decimal, we divide 4 by 9. Then, we multiply this decimal by 100 to get 44.4444444444, or roughly 44%.
To convert 7/21 to a percent, first we can write it as a decimal - 0.33333333333. To get this decimal, we divide 7 by 21. Then, we multiply this decimal by 100 to get 33.3333333333, or roughly 33%.
For this case, the first thing we must do is define a variable.
We have then:
x: number of hours it takes the second painter to paint the house working alone.
We have then that the equation that models the problem is:

From here, we clear the value of x.
We have then:
Answer:
It would take the second painter to paint the house by himself about 4.8 hours.
Answer:
Option A.
Step-by-step explanation:
1. BC ║ ED [Given}
2. m∠ABC = 70° [Given}
3. m∠CED = 30° [Given]
4. m∠ABC = m∠BED [Corresponding angle theorem]
5. m∠BEC + m∠CED = m∠BED [Angle addition postulate]
6. m∠BEC + 30° = 70° [Substitution property of equality]
7. ∠BEC = 40° [Subtraction property of equality]
Therefore, option A is the answer.
