66 minutes or 1 hour and 6 minutes
First divide 6 into 44 then multiply that number by 9 (:
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:
The number of servings which can be made by using gallon of milk are <u>128</u>.
Step-by-step explanation:
Given:
A recipe uses 1¼ cups of milk to make 10 servings of pudding.
Now, to find the servings which can be made by using gallon of milk.
Let the number of servings which can be made by using gallon of milk be 
.
So, we will convert the quantity from fraction into decimal first:
1¼ cups = 
Thus, 10 servings need 1.25 cups.
Then, by using proportion we get the quantity of servings:
(1 Gallon = 16 cups.)
⇒ 
Multiplying both sides by 16 we get:
⇒ 
⇒ 
⇒ 
Therefore, the number of servings which can be made by using gallon of milk are 128.

Step-by-step explanation:
The change is +9
Answer:
sandwiches n[S]=4
drinksn[D]=3
desserts[d]=2
total n[T]=9
number of possible choices for:
4 sandwiches=n[S]/n[T]=4/9
For
3 drinks=n[D]/n[T]=3/9=1/3
and
For 2 desserts=n[d]/n[T]=2/9
