Answer:
12.5
Step-by-step explanation:
You would solve by taking A=1/2(7.5+2.5)*2.5=12.5
Since the logarithmic function is the inverse of the exponential function, the domain of the logarithmic function is the range of the exponential function and that works the same both ways.
Answer:
"They add up to 180 degrees, because they are a pair of supplementary angles"
Step-by-step explanation:
When parallel lines are cut by transversal, it creates vertical angles (opposite of each other) that are equal AND also supplementary angles (that are adjacent to each other and fall in one line). They add up to 180 degrees.
Looking at the figure, we see angle 1 and 2 fall in one line which is 180 degrees. Thus, angles 1 and 2 are supplementary, they add up to 180 degrees.
The correct choice is "They add up to 180 degrees, because they are a pair of supplementary angles"
20×30would equal600.All you have to do is take the two cerca out of the way. Then you multiply2×3and you get6. Then you add the two ceros and get 600.
Ex.: 20×30:20- 0=2+30- 3=2×3=6+00=600
tadah
Divide the value of "b" by 2 and then square it.
(b / 2)²
= (120 / 2)²
= (60)²
= 3600
Therefore the value of z is 3600. That's at least what I believe lol
