Answer:
The land that is covered with an irrigation arm of 370 ft is 
Step-by-step explanation:
<u>Area of the circle</u>
Being r the radius of a circle, its area can be calculated as follows:
The irrigation arm acts as the radius of the irrigation circle, thus r=370 ft. The land covered is the area under the irrigation arm, thus:
The land that is covered with an irrigation arm of 370 ft is
mean = sum/n
mean = (5 + 7 + 7 + 9 + 12 + 16 + 21)/7
mean = 77/7
mean = 11
Answer:
Step-by-step explanation:
17x – 7y = 19
17x – 19 = 7y
y = (17/7)x - 19/7
Answer:
<h2><u><em>
x = 25</em></u></h2>
Step-by-step explanation:
What is the solution to this equation?
6 * (x - 5) = 4x + 20
6x - 30 = 4x + 20
2x = 20 + 30
2x = 50
x = 50 : 2
x = 25
-------------------
check
6 * ( 25 - 5) = 4 * 25 + 20
6 * 20 = 100 + 20
120 = 120
the answer is good
