A ship starts at sea level and then descends 20 feet in 4 1/2 minutes. How many feet did it descend per minute?
How many feet would it descend in 8 minutes?
Answer:
1. 4 1/2 can be converted into 4.30 / 20 = 0.125f per minute
2. it would descend 4.64 or 5f rounded in 8 minutes (8/0.125)
Answer:
4.45 feet p/m
35.56 feet per 8 minutes
Step-by-step explanation:
20 / (60x4.5) = 60 seconds = ( 1 x 4.5 minutes)
20/270=0.0740740741 1 = multiplier of feet/seconds
60 x 0.0740740741 1 =4.44444445 feet in one minute = 4.45feet
60 x 8 = 480 seconds (1 x 8 minutes)
480 x 0.0740740741 1 =35.5555556 feet
= 35.56feet in 8 minutes

For three consecutive homework assignments, each assignment had one more question than the previous assignment. The total number of questions on the three assignments is greater than 51 a.Write an inequality to represent this situation, where q is the number of questions on the first assignment
The inequality that represents the situation is:
[tex]3q + 3 > 51[/tex]
The first assignment had at least 17 questions.
On the first assignment, there were q questions.Each assignment had one more question than the previous one, so the second had q + 1 questions and the third had q + 2 questions.The total number of questions is:
[tex]T = q + q + 1 + q + 2 = 3q + 3[/tex]
Since the total is greater than 51, the inequality is:
[tex]3q + 3 > 51[/tex]
Solving the inequality, we have that:
[tex]3q > 48[/tex]
[tex]q > \frac{48}{3}[/tex]
[tex]q > 16[/tex]
Thus, it is found that the first assignment had at least 17 questions.

Step-by-step explanation:
The sum of 8th term of an A.P is 160 while to sum of the 20th term is 880. Find the 43rd term
The value of the 43rd term of the arithmetic sequence will be 482.
What is the sum of an arithmetic sequence?Let a be the first term, L be the last term, n be the number of terms, and d be a common difference.
Then the sum of the arithmetic sequence will be
Sₙ = (n / 2)[a + L]
Sₙ = (n/2) [2a + (n − 1) d]
An A.P.'s eighth term is worth 160 while their twentieth term is worth 880.
160 = (8/2)(2a + 7d)
2a + 7d = 40 ...1
880 = (20/2)(2a + 19d)
2a + 19d = 88 ...2
From equations 1 and 2,
40 - 7d + 19d = 88
12d = 48
d = 4
Then the value of 'a' is given as,
2a + 7(12) = 40
2a = 40 - 84
2a = -44
a = -22
The value of the 43rd term is given as,
aₙ = a + (n - 1)d
a₄₃ = - 22 + (43 - 1)(12)
a₄₃ = - 22 + 42 x 12
a₄₃ = - 22 + 504
a₄₃ = 482

Starting at (0,0) if you were to go 8 units down and 10 units left what coordinates
would you end up at? What quadrant would you be in?
Answer:
(-10, -8), third quadrant
Step-by-step explanation:
8 down from (0, 0) is the same as subtracting 8 from the y coordinate → (0, -8). 10 left from (0, -8) is the same as subtracting 10 from the x coordinate → (-10, -8). You would be in the third quadrant where both coordinates are negative.

how do you solve n - 8 > 5
Answer:
n great than 13.
hope this isn't wrong
The solution to the inequality is n > 13. This means that any value of n greater than 13 will satisfy the inequality.
Given is an inequality n - 8 > 5, we need to solve it,
To solve the inequality "n - 8 > 5," you can follow these steps:
Step 1: Add 8 to both sides of the inequality to isolate the variable n.
(n - 8) + 8 > 5 + 8
n - 8 + 8 > 13
n > 13
Step 2: Simplify the inequality.
n > 13
Hence the simplified inequality is n > 13.
