Answer:
1/3
Step by step:
Since the wheel is rotating at 20 revolutions per minute, to find the amount of rev’s per second would go as follows:
20/min = ?/second
convert each denominator to numerical form referring to seconds
20/60 = ?/1
Simplify
1/3 = ?/1
Find value of ?
1/3 = (1/3)/1
Simplify both sides completely
1/3 = 1/3
1/3
Answer:
1200 revolutions per second
Step-by-step explanation:
60 seconds per minute so multiply 60 x 20 to get 1,200

so,
angle DAB = 25° + 35°
= 60°
now,
angle DAB + angle ADC. = 180°
or, 60° + ADC = 180°
or, ADC = 180° - 60°
Therefore, ADC = 120°
therefore, the angles of the PARALLELOGRAM are 60° and 120°.
20x-10x+15
= 10x+15
Answer: 10x+15
The answer is C hope that helps
