Angle B = Angle D and the sum of these two is 70. X must be 180-60 = 110 degrees.
Answer:
Zero-elevation surface is a vertical datum that is used to describe a surface, such as that of a planet. The value of this datum is usually adopted by statute. This elevation is used, for example, to build a texture map from an agreed surface, such as a spheroid with dimensions defined by a mean surface gravity.
Step-by-step explanation:
Antonio have 3 dimes.
Step-by-step explanation:
Given,
Cost of snack = 45 cents
Worth of nickels = 15 cents
Worth of dime = x
Therefore,
Antonio has 30 cents worth of dimes.
10 cents = 1 dimes
30 cents =
30 cents = 3 dimes
Antonio have 3 dimes.

Answer:
24x²y²
Step-by-step explanation:
For k=0 to n, the k-th term of (a+b)^n is ...
(nCk)·a^(n-k)·b^k
You want the k=2 term for the n=4 expansion with a=2x and b=-y.
Then the third term of the expansion is ...
(4C2)·(2x)^2·(-y)^2 = 6·4x^2·y^2 = 24x^2y^2
_____
nCk = n!/(k!(n-k)!)
4C2 = 4!/(2!·2!) = (4·3)/(2·1) = 6
The mean temperature would be 5 c.
You figure this out by adding both values, 4 and 6, and dividing it by 2 because there are 2 values. So the equation would be 4 + 6 = 10
10 / 2 = 5
