Hi,
The equation: (3^6)^2 x (3^0)
Multiply:
=(729^2)(3^0)
=531441 (3^0)
Simplify:
=(531441) (1)
Multiply again:
=531441 or D. (3^12)
Have a great day!
Answer:
Her initial position was:
-29ft
Where we use the minus sign because this is below the ocean's surface.
Now we also know that she keeps descending at a rate of -29ft per minute, then if she keeps descending for t minutes, her position will be:
P(x) = -29ft - 29ft/min*t
Now, we also know that she does not want to descend more than 81ft below the ocean's surface, then we have the inequality:
P(x) ≥ -81ft
-29ft - 29ft/min*t ≥ -81ft
Now let's isolate t in one side:
- 29ft/min*t ≥ -81ft + 29ft = -52 ft
- 29ft/min*t ≥-52 ft
t ≤ -52ft/(- 29ft/min) = 1.79 min
Then the maximum amount of time that she can keep descending is 1.79 minutes.
Answer:
3w² = 243
Step-by-step explanation:
Width = w
Length = 3w
Area = 243 square units
length *width = 243
3w * w = 243
3w² = 243
Answer:
-6
Step-by-step explanation:
First, subtract 20 from both sides: 
Next, divide both sides by 2: 
Finally, write the equation: 
Answer:
Step-by-step explanation:
4/5 - 9/15 =
12/15 - 9/15 =
3/15 reduces to 1/5
so he spent 1/5 of an hr more cleaning
