Answer:
he would be at 16.50ft. below sea level.
Step-by-step explanation:
If you are below sea level, the feet would be negative. -11.75 + -4.75 would be -16.50ft below sea level.
Let me know if this helps!!!!

Answer:
- c(n) = 320·0.96^n
- 28 years
Step-by-step explanation:
Each year, the class size is multiplied by 1 - 4% = 96% = 0.96. After n years, it has been multiplied by that number n times. Repeated multiplication is signified using an exponent.
Class size (c) can be modeled by ...
c(n) = 320·0.96^n
__
You want to find n such that c(n) = 100. Put in that value and solve.
100 = 320·0.96^n
100/320 = 0.96^n . . . . . . . divide by 320
log(100/320) = n·log(0.96) . . . . . . . take logs
log(100/320)/log(0.96) = n ≈ 28.4932
In about 28 years, the class will have 100 students.
Answer:
Step-by-step explanation:
-9b + b = 2b - (b + 1)
Let's simplify by taking out the parenthesis.
-9b + b = 2b - b - 1
Now, we add like terms.
-8b = b - 1
Now, let's subtract b from both sides of the equal sign in order to isolate b.
-8b - b = b - 1 - b
Simplify!
-9b = -1
Divide both sides by -9.
-9b ÷ b = -1 ÷ -9
Simplify.
Answer:
The total weight of the grass seed is 
pounds
Step-by-step explanation:
Given
Total bags of seeds 
Weight of each bag 
Pounds
Total weight of the grass seed = Total number of bags of seeds * Weight of each bag
Total weight of the grass seed =
Pounds
The total weight of the grass seed is pounds
¹/9
Step-by-step explanation:
Of the total marbles (4 + 2 + 3) = 9 , the number of blue marbles is 2. The probability of drawing out a blue marble is therefore ²/9
A coin has two sides – therefor two possibilities in a toss (heads or tails). The probability of tossing either is therefore ½.
We MULTIPLY two probabilities when both conditions need to be satisfied at the same time. Therefore;
²/9 * ½ = ²/18
= ¹/9
