19 is the answer because you just divided 228 by 12
So we know that:
City A is -96ft in elevation
City C is -24ft in elevation
City D is (1/4C)ft in elevation.
So, knowing this we can make an equation: 1/4•-24/1=-24/4=-6
So from that, we get the result of City D being -6ft in elevation, or 6ft below sea level.
Answer:
(2xy)³
Step-by-step explanation:
According to the Power Rule of Exponents:

We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.
8 is a perfect cube of 2: ⇒ 2 × 2 × 2 = 2³ = 8
The cube of x is x³: ⇒ x × x × x = x³
The cube of y is y³ ⇒ y × y × y = y³
Hence, we can take the least common factors, (2xy) and raise them to the third power:
(2xy)³ = 2³x³y³ = 8x³y³
Therefore, the correct answer is: (2xy)³
Answer:
14.2%
Step-by-step explanation:
1. Find the new cost for Stock A:
2000x0.88=1760
2. Find the new cost for Stock B:
5720x0.85=4862
3. Find total sum of the original stocks:
2000+5720=7720
4. Find total sum of the new stocks:
1760+4862=6622
5. Find the decrease:
7720(1-x)=6622
Solve for x
x=14.2
