I’m going to say pre-algebra because that’s when I learned it in my school system but you may also learn it in algebra as well, College ready math can start in 8th grade math but I would think it would be in highschool.
Answer:
what do you mean?
Step-by-step explanation:
That would depend on the price u r originally paying because ur tip is a percentage of the original price.
Lets say u went out to eat and ur meal costs u $ 40. U plan on leaving a 20% tip. So ur tip would be 20% of 40....0.20 * 40 = 8...so a 20% tip on ur meal would be $ 8.
but if ur meal cost $ 25....and u left a 20% tip....20% of 25 = 0.20 * 25 = 5...so if ur meal was $ 25 and u left a 20% tip, u would be tipping $ 5
Answer:
The answer is P(6) is 44.
Step-by-step explanation:
Given:
If P(x) = x^2 + X + 2 and Q(x) = 3x^3 - 2.
Now, to find P(6).
Therefore, the answer is P(6) is 44.
Answer:
A) 2 units
Step-by-step explanation:
Given;
x² + y² - 4x - 4y + 4 = 0
Consider general circle equation;
(x - h)² + (y - k)² = r²
where;
(h , k ) is the center of the circle
r is the radius of the circle
x² + y² - 4x - 4y + 4 = 0
subtract 4 from both sides of the equation
x² + y² - 4x - 4y = - 4
square half of coefficient of x and y, and add them to both sides of the equation
x² + - 4x + (-2)² + y² - 4y + (-2)² = - 4 + (-2)² + (-2)²
factorize x and y
(x - 2)² + (y - 2)² = - 4 + 4 + 4
(x - 2)² + (y - 2)² = 4
(x - 2)² + (y - 2)² = 2²
Compare this final equation to general equation of a circle
(x - 2)² + (y - 2)² = 2²
(x - h)² + (y - k)² = r²
r = 2
Thus, the length of a radius of the circle is 2 units
