Answer:
2884.8 millimeters squared
Step-by-step explanation:
Given:
The radius of the disc is 35 millimeters, so the area of it is:
π = 3.14* = 3846.5
Then, we find out the area of the circular hold cut out of the bigger one, its radius is a haft of the radius of the bigger circle = 35/2 = 17.5
π = 3.14* =961.6
=> the area of the pendant = 3846.5 - 961.6 =2884.8 millimeters squared
Answer:
bc=cb
It is an example of commutative property.
Step-by-step explanation:
The given expression
By cross multiplying we can write given expression as
a+b=b+a
We can write commutative property in multiplication
ab=ba
Therefore, by using commutative property then we get
bc=cb
Hence, the given expression is an example of commutative property.

Step-by-step explanation:
8) If you were charged $671 for renting a car, how many days did you rent the car for?
Answer:
7) C = 247 + 53d
8) 8 days
Step-by-step explanation:
7)
Let "C" represent the total cost of renting a car.
Let "d" represent the number of days the car is rented.
The equation to represent the total cost of renting a car for a certain number of days is:
C = 247 + 53d
8)
To find the number of days the car was rented when the total cost is $671, we can substitute the values into the equation and solve for "D."
671 = 247 + 53d
424 = 53d
d = 8
So, the car was rented for 8 days.
