Step-by-step explanation:
Pie eaten by David and Peter = (1/4) + (2/5)
Remaining pie = 11/20
Answer:
Find the surface area of her notebook.
30 + 30 + 20 + 20 = 100
Now find the surface area of the square stickers.
2 + 2 + 2 + 2 = 8
So this is the surface area of one square, now multiply it by 8.
8 * 7 = 56
This is the surface area of all the stickers, now subtract it to the surface area of the notebook:
100 - 56 = 44
So 44 centimeters of the notebook cover will still be showing.
Step-by-step explanation:
One thing is you don't have to put the decimal point before the last two zeros. :D just saying... but if you want to then that's okay.
Anyway doing this scientific notation, you write the number down.
1) 13562600000000.00
Next you write times (x) 10
2) 13,562,600,000,000.00 x 10
Then you write the exponent of the number of places you need to move the decimal. REMEMBER: to make a standard notation to scientific notation the number has to be BETWEEN 1 and 10
3) 1.3562 x 10∧11
It might be 15 for you because you might count the two zeros behind the decimal point in standard form.
I hope this help you out :D
Given:
The sum of three numbers is 12 .
The sum of twice the first number, 3 times the second number, and 4 times the third number is 37 .
The difference between 7 times the first number and the second number is 25.
To find:
The three number.
Solution:
Let the three numbers are x, y and z respectively.
According to the question,
...(i)
...(ii)
...(iii)
From (iii), we get
Put value in (i).
...(iv)
Put value in (ii).
...(v)
Now, Multiply equation (iv) by 4 and subtract the result from (v).
Put x=4 in (iv).
Put x=4 in .
Therefore, the three numbers are 4, 3 and 5 respectively.
