Answer:
A(t) = π(8t)²
Step-by-step explanation:
Radius of a circular wave increases by 8 cm each second.
Every second radius of circular wave so the sequence of increase in radius will be,
8, 16, 24, 32.........(8t)
Here 't' = time
Since, area of a circle = πr²
Therefore, area of the circular wave after 't' seconds since the wave begins,
A(t) = π(8t)²
Answer:
17
Step-by-step explanation:
Given: y = 6; x + 35
Step 1: Equation
x - 3y
Step 2: Substitution
35 - 3(6)
Step 3: Solving
35 - 18 = 17
Answer:
17

Answer:
Addition and subtraction are inverse operations, Multiplication and division are inverse operations.Another pair of inverse mathematical operations is raising a number to an exponent "n" and taking the nth root of the number.
The sum of the measures of the angles in a triangle is 180°.
Therefore we have the equation:
2x° + 3x° + 55° = 180°
5x° + 55° = 180° <em>subtract 55° from both sides</em>
5x° = 125° <em>divdie both sides by 5</em>
x° = 25°
<h3>Answer: x = 25</h3>
hi <3
it would be option A and option C, i believe.
hope this helps :)
