Ricardo went jet skiing while on vacation. The jet ski rental cost a flat rate of $20, plus $16.75 per hour. Ricardo had $132.16. How much did he have left after 3 hours of jet ski riding?
$50.25
$61.91
$81.91
$70.25
By solving a linear equation, we can see that after 3 hours Ricardo has $61.91
How much did he have left after 3 hours of jet ski riding?We know that Ricardo has $132.16, and he rents a jet sky that costs $20 plus $16.75 per hour.
So, the cost of renting the jet sky for x hours is given by the linear equation:
C(x) = $20 + x*$16.75
The cost of renting this for 3 hours is:
C(3) = $20 + 3*$16.75 = $70.25
Subtracting this from what Ricardo had:
$132.16 - $70.25 = $61.91
So the correct option is the second one.

PLEASE HELP Finding the initial amount and rate of change given a table for a linear function
The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively
How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 467) and (10, 647)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (647 - 467)/(10 - 2)
Evaluate
Rate = 22.5
This means that the rate of change is $22.5
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = 22.5
So, we have
y = 22.5(x - x1) + y1
Using one of the points, we have
y = 22.5(x - 6) + 467
Set x = 0
So, we have
y = 22.5(0 - 6) + 467
Evaluate
y = 332
Hence, the initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

Answer:
MP = 29
Step-by-step explanation:
Given:
The entire line (MP) is equal to 5y + 9MN = 17NP = 3yMN + NP = MP
17 + 3y = 5y + 9
Find what y =____
17 + 3y = 5y + 9
subtract 9 from both sides
17 - 9 + 3y = 5y + 9 - 9
8 + 3y = 5y
subtract 3y from both sides
8 + 3y - 3y = 5y - 3y
8 = 2y
divided both sides by 2 to get y alone
8/2 = 2y/2
4 = y
Now plug in y to MP to find its length
5(4) + 9 = 20 + 9 = 29
MP = 29
To find NP, plug in y as well
3y = 3(4) = 12
NP = 12
Check:
MN + NP = MP
17 + 12 = 29 yes!!!!

The arithmetic sequence AP's 32nd term is estimated to be 127.
What exactly is an arithmetic sequence AP?An arithmetic progression (AP) in mathematics is a list or sequence of numbers within which each term is acquired by adding a sequence to the term before it.
The fixed number is denoted by the letter 'd' in the arithmetic progression's common difference.nth term of an AP: an = a + (n - 1) dThe common difference => d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.The sum of n terms of an AP's => Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the last term of the AP.Finally, the response to the question;
The numbers in the provided sequence are as follows:
34,37,40,43, ...........
There are 32 terms in the series, so we must obtain the 32nd number.
Suppose the first term is 'a₁' = 34.
Suppose 'a₂' = 37 be the second term.
Suppose 'a₃' = 40 be the third term.
The common difference between the two consecutive terms of an AP that are equal is 'd.'
d = a₂ - a₁
Put the values in the preceding formula; the 32nd term is
d = 37 - 34
d = 3
The nth term equation is now used to calculate.
nth term of an AP: an = a + (n - 1) dTotal number of terms is; n = 32First term is a = 34common difference d = 3Substitute all of the values in the formula now.
a₃₂ = a + (n - 1) d
a₃₂ = 34 + (32 - 1)(3)
a₃₂ = 34 + 96 - 3
a₃₂ = 127
Thus, the arithmetic sequence's 32nd term is evaluated to be 127.

By elimination, the solution of the system of equations, r + 3s = 7 and 2r - s = 7, is (r , s) = (4 , 1).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in r and s, a variable should be eliminated by adding/subtracting the two equations.
First, multiply the first equation by 2.
r + 3s = 7 ⇒ 2r + 6s = 14 (equation 1)
Subtracting the two equations will eliminate the variable r.
2r + 6s = 14 (equation 1)
2r - s = 7 (equation 2)
7s = 7
s = 1
Substitute the value of s to any of the two equations and solve for r.
2r - s = 7 (equation 2)
2r - 1 = 7
2r = 7 + 1
2r = 8
r = 4
Hence, the solution of the system of equations is (r , s) = (4 , 1).

How to write and solve a system of equations that models this problem.To solve this question, we use the following representations:
x represents the fruit pies
y represents the fruit juice
A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
1.89x + 1.56y = 140.13 ---- the total cost
x + y = 82 --- the number of sales
Make x the subject in x + y = 82
So, we have
x = 82 - y
Substitute x = 82 - y in 1.89x + 1.56y = 140.13
1.89(82 - y) + 1.56y = 140.13
Expand
154.98 - 1.89y + 1.56y = 140.13

The 32nd term of the arithmetic sequence AP is computed to be 12.5.
What is an AP arithmetic sequence?In mathematics, an arithmetic progression (AP) is a list or sequence of numbers in which each term is attained by adding a pattern to the term before it.
With in arithmetic progression's common difference, the fixed number is marked by the letter 'd.'The common difference => d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1.nth term of an AP: an = a + (n - 1) dThe sum of n terms of an AP's => Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the last term of the AP.Finally, here is the answer to the question;
The following are the numbers in the presented sequence:
0.1,0.5,0.9,1.3, ...........
Because the series contains 32 terms, we must find the 32nd number.
Assume the first term is'a₁' = 0.1.
Assume 'a₂' = 0.5 is the second term.
Assume the third term is 'a₃' = 0.9
'd' is the common difference between two consecutive terms of an AP that are equal.
d = a₂ - a₁
Put the values in the preceding formula; the 32nd term is
d = 0.5 - 0.1
d = 0.4
The nth term equation is found by the formula;
nth term of an AP: an = a + (n - 1) dTotal number of terms is; n = 32Initial term is a = 0.1Common difference d = 0.4Substitute the given values in the formula;
a₃₂ = a + (n - 1) d
a₃₂ = 0.1 + (32 - 1)(0.4)
a₃₂ = 0.1 + 12.8 - 0.4
a₃₂ = 12.5
Therefore, the arithmetic sequence's 32nd term value is estimated to be 12.5.
