Answer:
x = - 5
Step-by-step explanation:
Given
5x + 7 = 2x - 8 ( subtract 2x from both sides )
3x + 7 = - 8 ( subtract 7 from both sides )
3x = - 15 ( divide both sides by 3 )
x = - 5
Answer:
49π sq. units
Step-by-step explanation:
Find the diagram attached
We can find the area of the given circle
Given
diameter of the circle d = 14
Area of the circle = πd²/4
Substitute the given diameter
Area of the circle = π(14)²/4
Area of the circle = 196π/4
Area of the circle = 49π sq. units
Hence the exact answer in terms of π is 49π sq. units
Answer:
If its written as the fourth root of (81^3) the answer is 27.
Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.
1) we calculate the number of minutes from 6:10 to 7:00
number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.
2)
We know that:
60 minutes of a clock have turned -360º
Then:
60 minutes of a clock------------------------- -360º
50 minutes of a clock------------------------- x
x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º
Answer: A. -300º
