Answer:
Sofia is not correct. 3% written as a decimal is 0.03
Step-by-step explanation:
The decimal form of a percent is found by moving the decimal point two times to the left (For example 3.0 to 0.03)
4s and 11s are like terms so you add them. You get 15s and now you add the 3t plus t because they are also like terms. Your result is 15s + 3t.
Complementary angles ⇒ the angles add up to 90°
∠A and ∠B are complementary ⇒ ∠A + ∠B = 90°
∠A + ∠B = 90°
Plug in the values for ∠A and ∠B:
(3x - 8) + (5x + 10) = 90
Open the brackets:
3x - 8 + 5x + 10 = 90
Combine like terms:
8x + 2 = 90
Subtract 2 from both sides:
8x = 88
Divide both sides by 8:
x = 11
Answer: x = 11
The function is discontinuous at x=8 because as x approaches 8 from the left, f(x) approaches -1 but as x approaches 8 from the right, f(x) approaches 1 and -1 and 1 are not equal.
I think 0.50 Hope that helped! Have a good day!
