1. C.
The rule of powers is that when a parenthesis is raised to a power, you multiply the two numbers. Since it is being raised to the second power, it needs to have a 10 in the parenthesis. That would make 20.
2. B
Firstly 10^2 = 100, so we know that the number must be 10. That leaves us with just A and B. Then we know the same thing from the previous equation, that they need to be multiplied together.

14600 plus 219 = 14819
Answer:
see explanation
Step-by-step explanation:
(a)
Since Y is the midpoint of XZ , then
XY = YZ , that is
4a - 4 = 3a + 2 ( subtract 3a from both sides )
a - 4 = 2 ( add 4 to both sides )
a = 6
(b)
XY = 4a - 4 = 4(6) - 4 = 24 - 4 = 20
XZ = 4a - 4 + 3a + 2 = 7a - 2 = 7(6) - 2 = 42 - 2 = 40
Answer:
11 2/3
Step-by-step explanation:
2 1/3 * 5
Change the mixed number to an improper fraction
2 /13 = ( 3*2+1)/3 = 7/3
7/3 * 5/1
35/3
Now change it back to a mixed number
3 goes back into 35 11 times with 2 left over
11 2/3
