Quiana took out a loan to pay for a new car. Initially, she owed the lender $15,234.68. She has repaid $247.43 of the loan each month for the past 5 months. What is the net change to the loan from Quiana’s perspective over the past 5 months?
Write a rational number to express the initial loan amount as it relates to Quiana’s bank account.
Answers
Initial amount of loan = $15,234.68
Monthly payment = $247.43
Number of months = 5
Required Information:
Net change in loan = ?
Answer:
Net change in loan = $1,237.15 = $1,237(3/20)
Step-by-step explanation:
Quiana owed her lender an amount of 15,234.68 initially, she repaid the lender each month with an amount of $247.43 for 5 months, so the total amount that she repaid is
Total amount repaid = Monthly payment*Number of months
Total amount repaid = $247.43 × 5
Total amount repaid = $1,237.15
The remaining owed amount is given by
Balance = Initial amount of loan - Total amount repaid
Balance = $15,234.68 - $1237.15
Balance = $13,997.53
So the net change to the loan from Quiana's perspective over the past 5 months is,
Net change in loan = Initial amount of loan - Balance
Net change in loan = $15,234.68 - $13,997.53
Net change in loan = $1,237.15
or
Net change in loan = $1,237(3/20)
Therefore, the net change to the loan from Quiana's perspective over the past 5 months is $1,237.15
To ship a package, Company 1 charges $10 for the first pound and 0.45 for each additional pound. Company 2 charges $14 for the first pound and 0.30 for each additional pound.
What is the equation for "p", the number of pounds it would take for the cost of the two shipping companies to be the same?
Answers
Answer:
answer is on the bottom
Step-by-step explanation:
Company 1: y=0.45x+10
company 2: y=0.30x+14
To find when they are both the same, put an equal sign and solve:
0.45x+10=0.30x+14
-10 -10
0.45x=0.30x+4
-0.30x -0.30x
0.15x=4
divide by 0.15 on both sides and you got ur answer :) happy to help

Answers
8.25g+65=683.75
As you can see in the question it says that each gallon is $8.25. Since each gallon is $8.25 then the g for gallons would go after 8.25 in the equation.
Since he but one irrigation unit for $65, then we only add 65. Lastly, the total cost is $683.75. This means that this number goes behind the equal sign.

the measure of angle ABD is 134 degrees. what is the measure of x? What angle relationship is needed to be solved?
Answers
Explanation
The angles ABD and DBC are supplementary since they form a straight line. That means they add to 180 degrees.
(angle ABD) + (angle DBC) = 180
(134) + (2x) = 180
2x = 180-134
2x = 46
x = 46/2
x = 23
Answer: x=23 and the angle relation used was supplementary angles
Step-by-step explanation:
first, you know that angle abd is 134 so you subtract that from 180 and divide it by 2 because angle cbd is 2x and you know they equal 180 because they make a straight line.

Which of the following is the solution set of x < 5?

B) x = {5, 6, 7, 8, 9, ... }
C) x = {4, 3, 2, 1, ... }
D) x = {3, 4, 5, 6, 7, ... }
with solution pls, show the solution how did you get the answer
Answers
The best answer from the options provided is C, because "x<5" means all the numbers less than 5 and answer C only has integers that are less than 5.
Now C isn't a perfect answer, because C leaves out all the other fractions and decimals like 4.3 and 3/4 that are also less than 5, but aren't in answer C.
But given your choices, A, B, and D are not the answer, since they all have a number included that's greater than OR equal to 5.
To see why, let's break down the inequality x < 5. This inequality means that x can be any number that is less than 5, but not including 5 itself. In other words, x can be any number in the open interval (-∞, 5).
The solution set for this inequality is any set of numbers that satisfies this condition. The set of numbers in option B) {5, 6, 7, 8, 9, ... } is the only set that satisfies this condition, since all of these numbers are less than 5.
Option A) {5, 4, 3, 2, 1, ... } includes 5, which is not a solution to the inequality x < 5.
Option C) {4, 3, 2, 1, ... } does not include any numbers greater than or equal to 5, so it does not satisfy the inequality x < 5.
Option D) {3, 4, 5, 6, 7, ... } includes 5, which is not a solution to the inequality x < 5.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answer:
[ 2] − | −5 + 7 |
Step-by-step explanation:
Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.
Step 1) Solve. | −5 + 7 | = 2.
Step 2) Find which other absolute value is equal to -2.
After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.
We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
We start by simplifying | −5 + 7 |:
| −5 + 7 | = | 2 | = 2
Now we can simplify each of the answer choices:
[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2
We see that only choice [2], when added to | −5 + 7 |, will equal zero:
2 + (−2) = 0
Therefore, the answer is [2] | +5 − 7 |.
