You convert a decimal to a fraction by putting the digits to the right of the decimal point over "1" followed by the same number of zeros. (Most folks learn this in 3rd or 4th grade.)
0.66 = 66/100 . . . . . 2 decimals, so the denominator is 100
Then you reduce the fraction by canceling common factors. It helps to know your times tables and divisibility rules. (Or you can have your calculator do it.)
0.66 = 66/100 = 33/50
1.00 = 100/100 = 1
Your answer is: 2x^6-x^4+5x^3+2x^2+1\x^2
3z + 6
3z and 6 has greatest common factor, that is 3. Divide 3z and 6 by the greatest common factor (3).
3z ÷ 3 = z
6 ÷ 3 = 2
So, we could work on the expression as following.
3z + 6
= 3 × z + 3 × 2
From the expression above, we should separate 3 from z and 2 by a parenthesis to make distributive property.
3 × z + 3 × 2
= 3(z + 2)
SUMMARY
3z + 6
= 3 × z + 3 × 2
= 3(z + 2)
Answer:
23 SQUARE feet i think
Step-by-step explanation:
The formula for volume of a cone = PI x r^2 x h/3
PI = 3.14
r = 8.5/2 = 4.25
h = 4.5
Volume = 3.14 x 4.25^2 x 4.5/3
Volume = 3.14 x 18.0625 x 1.5
Volume = 85.074375
Rounded to the nearest hundredth = 85.07 cubic cm.
