Answer: 45 degrees
Step-by-step explanation:
Base angle theorem states that the base angles of an isosceles triangle are congruent, or the same.
Step-by-step explanation:
subtract-13 from -13 get zero
then, subtract 13 from 77 =64
then do divide 15 from 15
then divide 15 from 64 = 4.26 repeat
10 to the 5th power is 100,000. 2 X 5 is 10.
10 X 100,000 is one million.
the answer is 1,000,000. (one million)
Answer:
30%
Step-by-step explanation:
So, 20/20 turns to 14/20. How much was taken away? 6/20. What times 20 is 100? 5. So, 5 x 6 is 30. So, there is a 30% decrease
Answer:
Option C is correct.
Constant of variation k = -0.5
Step-by-step explanation:
The direct variation says that:
then, the equation is of the form: 
.....[1] where k is the constant of variation.
Given the table:
x f(x)=y
0 0
2 -1
4 -2
7 -3.5
Consider any values from the tables
x = 4 and y=f(x) = -2
Substitute these values in equation [1] we have;
Divide both sides by 4 we get;
Therefore, the constant of variation is, -0.5
