Answer:
1988920000000000
Step-by-step explanation:
1.98892 x 1000000000000000 (15 zeros)
The upper number (in this case 15) indicates the amount of zeros after the 1 (10 is 10^1, 100 is 10^2)
Answer: 14.7
Step-by-step explanation:
Data : 12,18
Total Number of Values, N = 2
Step 1 : Find 1 / N
1 / N = 1 / 2 = 0.5
Step 2 : Find mean
GM = ( 12 * 18 )^ 0.5
= 14.7
Answer:
4. C
5. A
6. D
Step-by-step explanation:
The volume of the car is 1800cm^3 which is equivalent to 0.0018m^3
<h3>Scale modelling</h3>
Given the scale factor that model of a car is amde to a scale of 1:40, Giving that the model as 45cm^3, this means that;
1 = 45cm^2
Determine the volume of the car
40 = x
Find the ratio
1/40 = 45/x
x = 40*45
x = 1800cm^3
x = 0.0018m^3
Hence the volume of the car is 1800cm^3 which is equivalent to 0.0018m^3
