Not sure but you can figure it out.
Tia went home and said to her mom,"I learned that 10 to the power of 4 is the same as 40,000."
Tia made a mistake in her thinking. Exponent represents the number of zeros.
means we multiply 10 four times

For exponent 4, we put 4 zeros. So answer is 10,000.
Answer:
X = 45°
Y = 72°
Step-by-step explanation:
There is a supplementary angle (an pair of angles that create a straight line is equal to 180°) and there is the rule that all three angles in a triangle equal 180° as well.
Solution for the given fractions
7/9 + 2/3 = ?
The common denominator of the two fractions is: 9
7/9 = (1*7)/(1*9) = 7/9
2/3 = (2*3)/(3*3) = 6/9
Fractions adjusted to a common denominator
7/9 + 2/3 = 7/9 + 6/9
(6+7)/9 = 13/9
