Answer:
128.57 degrees per angle
Step-by-step explanation:
There is a total of 900 degrees in a seven sided polygon. Divide the number by seven and you get your answer.
If the crew members used 3 gal of paint per hour and bought 30 gal of paint for a job, then they will work 30:3=10 hours.
- They start at x=0 hours with y=30 gal of paint;
- They end at x=10 hours with y=0 gal of paint (they worked until they used all the paint).
- The dependence between x and y is linear.
Conclusion: the only possible sketch is A.
Answer: correct choice is A.
The answer to this question is choice B
Answer:
<u>Solved only ticked ones</u>
- 4a² + 49b² = (2a + 7b)² - 28ab = 11² - 28*2 = 65
- 4x² + 9y² = (2x + 3y)² - 12xy = 12² - 12*6 = 72
- 4x² + 9y² = (2x - 3y)² + 12xy = 2² + 12*8 = 100
- 16x² + 25y² = (4x - 5y)² + 40xy = 6² + 40*8 = 356
Answer:
2>y
Step-by-step explanation:
4/9>y/18
Here u cross multiple
4*18 >9*y
72>9y
the you divide both sides by 9
72/9>9y/9
8>y
