You just need to multiply the length with the ratio
for example, if the ratio is :2w : 3L , the actual width would be 2/3 x 27
= 18 cm
It says "She grows around 6 inches per year."
This means that the rate of change is 6.
27 + (6 * y)
y = how many years pass.
Hope This Helped! Good Luck!
The equivalent expressions are: A and C
Answer:
15) 3.2
17) 13.4
Step-by-step explanation:
To find the missing lengths, you need to use the Pythagorean theorem:
a² + b² = c²
In this form, "c" represents the length of the hypotenuse and "a" and "b" represent the lengths of the other two sides.
You are trying to find one of the side lengths (not the hypotenuse) in 15). To find the other length, you can plug the other values into the equation and simplify to find "b".
15) a = 4.1 c = 5.2
a² + b² = c² <----- Pythagreom Theorem
(4.1)² + b² = (5.2)² <----- Plug values in for "a" and "c"
16.81 + b² = 27.04 <----- Raise numbers to the power of 2
b² = 10.23 <----- Subtract 16.81 from both sides
b = 3.2 <----- Take the square root of both sides
You are trying to find the hypotenuse in 17). Since you have been given the lengths of the other sides, you can plug them into the equations and simplify to find "c".
17) a = 4.4 b = 12.7
a² + b² = c² <----- Pythagreom Theorem
(4.4)² + (12.7)² = c² <----- Plug values in for "a" and "b"
19.36 + 161.29 = c² <----- Raise numbers to the power of 2
180.65 = c² <----- Add
13.4 = c <----- Take the square root of both sides
Answer:
The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π = 
⇒ answer C
Step-by-step explanation:
In any circle there is a constant ratio between the circumference of the circle and its diameter
This constant ratio is called π
∵ The formula of the circumference of a circle is C = π d,
where d is the diameter of the circle
- Divide both sides by d
∴ 
= π
- Switch the two sides
∴ π =
∵ The diameter of the circle is 5 centimeters
∴ π =
The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =
