Answer:
circle P has a circumference of 800mm which is equal to 80cm
circle Q is 200cm
circle R is 4m which is equal to 400cm
You will get the sum of the distances by placing the figures under one measurement that is meters
And so add the figures in cm(200+400+80) and get 680
Then convert this to meters and get 6.8m
Hence your answer is C
Answer:
x = 12
Step-by-step explanation:
Given
4(x - 5) = 8x + 4 - 6x ← distribute left side and simplify right side
4x - 20 = 2x + 4 ( subtract 2x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Answer:
A:
The decreasing value of car 1 can be represented by an exponential function and car 2 by a linear function
B:
Car 1: f(x) = 
Car 2: f(x) = 18500 - 1000x
C:
Car 1 would be $10600.40 after 9 years
Car 2 would be $9500.00 after 9 years
There is a significant difference of $1100.40 in value.
Step-by-step explanation:
12% of 120 is 14.4
Change the percentage into a decimal by dividing over 100:
12 / 100 = 0.12
Multiply:
0.12 × 120 = 14.4
