(2x + 29) + 91 = 180.

This is because they add to form a straight line which is 180 degrees, in other words the angles are supplementary.

2x + 29 = 89 (Subtract 91 from each side)

2x = 60 (Subtract 29 from each side)

x = 30 (Divide 2 from each side)

x = 30

The answer is B

The total cost for a production process is equal to $1,000 plus two times the number of units produced. The mean and variance fo
Andrej [43]

Answer:

\mu_p=2000\\\\\sigma_p^2=3600

Step-by-step explanation:

Let X be the number of units produced, and P be the cost of production.

#Given that \mu_x=500, \sigma_x^2=900

Cost of production can be calculated as:

P=1000+2X

#Mean of the total cost is calculated as;

\mu_p=1000+2\mu_x\\\\=1000+2(500)\\\\=2000

Hence, the mean cost of production is $2,000

#Variance of the total cost is calculated as;

\sigma_p^2=2^2\sigma_x^2\\\\=2^\times 900\\\\=3600

Hence, the variancecost of production is $3,600

I'm in algebra 1 please help i'm so lost
lesya692 [45]
Its a square, so all the sides are equal. Also, since the area of a square (rectangles) is equal to the height times the length, which are both the same, the area of the square is equal to x², where x is the length of any one side of the square, x²=256. now you square root both sides of that equation, x=√256, and the square root of 256 is 16. 

Tl;Dr: each side is 16 feet long.
