We need to find 30% of 20 gallons.
1) We can write a proportion
20 gallons ---- 100%
x gallons --------30%
x = 20*30/100 = 6 gallons
2) Or we can write 30% as decimal.
30% = 30/100 = 0.3
0.3 of 20 = 0.3*20 =6 gallons
Answer 6 gallons are used efficiently.
Answer:
64
Step-by-step explanation:
To find the value of x, you do 10-2 to get 8. Next, you do 8x8 to get 64.
The simplest radical form is
Explanation:
The expression is
To determine the radical form, let us write the number 68 as a product of prime factors.
Thus, we have,
Since, 2, 17 are prime factors and hence, no further factorization is possible.
Hence, it can be written as,
Applying the radical rule , we have,
Simplifying, we have,
Thus, the simplest radical form is
Answer:
Negative, linear
Step-by-step explanation:
If you look at it, it is relatively in a line and the values are going down.
