2.4 cm2
First, convert the millimeters to centimeters
1mm = .1 cm
So, 4 mm=.4 cm
And since there in the same unit, you can now solve
Formula: b x h
6 cm (base) x .4 cm (height) = 2.4 cm
In cm, it is 2.4 cm
The answer is 2.4
0246 is unlike the others, You can't have a 0 in front of a large number like that without the use of a decimal
Hello from MrBillDoesMath!
Answer:
Discussion:
I stared at the numbers 19, 29, 39, 49, 59, 69,... for a second and noticed that adding 10 to any number gives the next number to the right. For example,
19 + 10 = 29
29 + 10 = 39
39 + 10 = 49
etc.....
A recursive formula would be:
a(0) = 19
a(n+1) = a(n) + 10 if n >= 0

Answer: There are 20 ways and 1680 ways respectively.
Step-by-step explanation:
Since we have given that
Total number of blocks = 6
Number of red blocks = 3
Number of green blocks = 3
So, Number of patterns she can make by placing them all in a line is given by

If there are 3 white blocks
so, total number of white blocks becomes 9
So, Number of total pattern she can make by placing all nine blocks in a line is given by

Hence, there are 20 ways and 1680 ways respectively.
