Answer:
a.) 10 months
b.) Kool Karate
c.) Karate Klub
Step-by-step explanation:
Karate Klub : y=25x+200
Kool Karate : y=35x+100
A.) First, set the equations equal to each other then solve for x.
take away 100 from both sides
take away 25x from both sides
divide 10 from both sides so x can be by itself and equal to 1
This means that at 10 months, the cost is the same for both.
B.) Substitute 6 for x in both equations
Karate Klub :
Kool Karate :
The cost for Kool Karate is cheaper, so that is what he should join.
C.) Substitute 12 for x in both equations.
x=12 because there are 12 months in a year.
Karate Klub:
Kool Karate:
The cost for Karate Klub is cheaper, so that is what he should join.
Answer:
28.84
Step-by-step explanation:
Simplify the inside of root first
147 / 3 = 49
49 + 3 = 52
4 (root) 52 = 28.8444102
Answer:y = MX+b
Step-by-step explanation:
Perimeter of the shape = 27.15 units.
Area = 32.3 units²
<h3>How to Find the Perimeter and Area of a Composite Shape?</h3>
The Perimeter of the shape = 1/2(perimeter of circle) + hypotenuse and height of the triangle
Perimeter = = 1/2(2π(5/2)) + [√(9² + 5²)] + 9 = 7.85 + 10.3 + 9 = 27.15 units.
Area = 1/2(area of circle) + area of triangle = 1/2(πr²) + 1/2(bh)
Area = 1/2(π2.5²) + 1/2(5)(9)
Area = 9.8 + 22.5
Area = 32.3 units²
