V = l * w * h
240 = 20* h
divide both sides by 20
12 = h
height = 12 inches
First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
=
Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!
It should be 21 20. Sorry if I got it wrong
We know that 1 million has 6 zeros. This means 1 million has 7 place values: one for the 1 and 6 for the zeros.
50 has 1 more place value than one, so 50 million has 1 more place value than 1 million.
So, 50 million has 8 place values.
As an overview, an arithmetic series has a common difference (d) while a geometric series has a common ratio (r). Common difference is calculated by subtracting two consecutive numbers. Common ratio is calculates by dividing two consecutive numbers.
1.) Geometric series (r = 1/2)
2.) Neither
3.) d = 3
19 - 16 = 3; 22 - 19 = 3; 25 - 22 = 3
4.) d = 2.8
5.8 - 3 = 2.8; 8.6 - 5.8 = 2.8; 11.4 - 8.6 = 2.8
5.) r = 4
24/6 = 4; 96/24 = 4; 384/96 = 4
6.) r = 4
12/3 = 4
