So let's call the missing angles A, B, and C. We know that A + B + C = 180 and we also know that A = B and that C = A + B - 40. So our equation looks like this
180 = 4A - 40 and we add 40 on both sides of the equal sign and get
220 = 4A and we divide on both sides of the equal sign by 4 to get
55 = A So that means B = 55 as well. That means 55 + 55 = 110 and 110 - 40 = 70 So C = 70 and to check, 55 + 55 + 70 = 180.
The measures of the three angles are; 55 degrees, 55 degrees, and 70 degrees.
Answer: 87.5%
Step-by-step explanation:
From the question, we are informed that a rancher uses 1400 acres of his property for cattle grazing amd that the area of the property is 1600 acres. To get the percentage used for cattle grazing, we divide 1400 by 1600 and then multiply the result by 100%. Mathematically, this will be expressed as:
= 1400/1600 × 100
= 0.875 × 100%
= 87.5%
The percent that is used for cattle grazing is 87.5%.
Yes, it would be about 61%.
2.00/6 = $0.33 rounded to the nearest penny, it actually is $0.333333333333 (infinite)
I hope this helped you out :)
Answer:
σ =2√2 .....
Step-by-step explanation:
Lets find the mean first
mean = 2+4+6+8+10/5
m = 30/5
m = 6
σ =√1/5[(2-6)²+(4-6)²+(6-6)²+(8-6)²+(10-6)²]
σ = √1/5[(-4)²+(-2)²+(0)²+(2)²+(4)²]
σ=√1/5[(16+4+0+4+16)]
σ = √1/5(40)
σ = √8
Take the square root of 8.
σ =2√2 .....
