The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
The area of the circle is given by the formula,
As we know that the ratio of the area of the two watches is 16:25. And we also know that the area of a circle is given by the formula,
Now, as we know that the ratio of the area of the watches can be written as,
Hence, the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.

Answer:
4:5
Step-by-step explanation:
Let r be the radius of small watch
Area of small watch=π
Let R be radius of larger watch= π
Area of larger watch= π
It is given that the ratio of their areas= 16:25
=
π: π= 16:25
=
r:R= 4:5
Hence, the ratio of their radii= 4:5
Hence, the correct answer is 4:5
Answer:
The integer that represents the average decrease in value per year will be 1800.
Step-by-step explanation:
Suppose, the average decrease in value per year is dollar.
So, the amount of decrease in three years will be: dollar.
Given that, the value of the car is decreased $5400 over the last three years. So, the equation will be......
Thus, the integer that represents the average decrease in value per year will be 1800.
The three different ways to calculate the equation A = 3 x 2 x 4 is
A = 6 x 4
A = 3 x 8
A = 12 x 2
What is a an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A = 3 x 2 x 4
Now , the value of the equation A is A = 24
Now , the number 24 can be written as a product of different numbers
The factors of the number 24 = 1 , 2 , 3 , 4 , 6 , 8 , 12 , 24
So , the three different ways to calculate the equation A = 3 x 2 x 4 is
A = 24
The first equation ,
A = 6 x 4
The second equation ,
A = 3 x 8
The third equation ,
A = 12 x 2
Hence , The three different ways to calculate the equation A = 3 x 2 x 4 is
A = 6 x 4
A = 3 x 8
A = 12 x 2

Step-by-step explanation:
sqrt( -6) * sqrt(-24)
We know that sqrt(a b) = sqrt(a) sqrt(b)
sqrt(6) sqrt(-1) * sqrt(24) sqrt(-1)
We know that sqrt(-1) = i
sqrt(6) i * sqrt(24) i
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(6*24) i*i
sqrt(144) i^2
12 i^2
We know that i^2 = -1
12 (-1)
-12
