Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding. The speed limit is 65 mph and Sally has traveled 97 km in 102 minutes. How fast was Sally's average speed in mph? In a complete sentence, explain whether or not Sally deserves a ticket?
Answer:
35.5 mph
Step-by-step explanation:
We are given that Sally Leadfoot was pulled over on her way from Syracuse to Ithaca by an officer claiming she was speeding.
Speed limit =65 mph
Sally traveled distance 97 km in 102 minutes
We have to find the Sally's average speed in mph
Time =102 minutes
We know that 1 hour =60 minutes
[tex]102 minutes=\frac{102}{60}=1.7 [/tex]hours
We know that 1 km=0.621371
97 km=[tex]0.621371 \times 97=60.272987[/tex]miles
Average speed =[tex]\frac{60.272987}{1.7}=35.45 mph[/tex]
Average speed of Sally's =35.5 mph
Hence, average speed of Sally is less than 65 mph .Therefore, she was not fast speeding and she deserves a ticket.
Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.20 per pound, how many pounds of lemon drops are need to make the mix cost $1.48 per pound. formulate an equation and then solve it to find how many pounds of lemon drops are needed. show all of your work
L = lemon drops
J = jelly beans
L +J = 100
L=100-J
1.90L + 1.20J=1.48*100
1.90(100-j) +1.20J =148
190-1.90J+1.20J=148
190-0.7J=148
-0.7J=-42
J = 60
L=100-60 = 40
40 pounds of Lemon Drops are needed
Final answer:
40 pounds of lemon drops are needed.
Explanation:
To find out how many pounds of lemon drops are needed to make a 100-pound mix that costs $1.48 per pound, we can set up a system of equations. Let L represent the number of pounds of lemon drops and J represent the number of pounds of jelly beans.
Since the total weight of the mix is 100 pounds:
L + J = 100
Given the cost of lemon drops is $1.90 per pound and jelly beans cost $1.20 per pound, and the entire mix should cost $1.48 per pound:
1.90L + 1.20J = 100 * 1.48
We already have that L + J = 100, so J can be expressed as 100 - L. Substituting J in the second equation we get:
1.90L + 1.20(100 - L) = 148
Solving for L:
1.90L + 120 - 1.20L = 148
0.70L = 28
L = 28 / 0.70
L = 40
Therefore, 40 pounds of lemon drops are needed for the mix.

The sum of the reciprocals of two consecutive integers is startfraction 11 over 30 endfraction 11 30. find the two integers.
The consecutive integers are 5 and 6.
What are integers?Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Given:
The sum of the reciprocals of two consecutive integers is 11/30.
Let the integers be n and n+1.
Then,
1/n + 1/n+1 = 11/30
{n + 1 + n}/n(n+ 1) = 11/30
30(2n+1 ) = 11(n²+n)
60n + 30 = 11n² + 11n
11n² - 49n - 30 = 0
(11n +6) (n-5) = 0
Only taking,
n = 5.
So, 5 and 6.
Therefore, 5 and 6 are the integers.

How do you know when the function is in simplified form?
Final answer:
A function is in simplified form when all unnecessary terms have been eliminated, subscripts are used appropriately, and it uses the most compact and standard notation possible. Always verify the reasonableness of the simplified function.
Explanation:
To determine when a function is in simplified form, several steps should be followed:
Eliminate terms wherever possible to simplify the algebra.Use the simplified subscript in the final formula.Do not write the subscript if it is one, as it is understood to be implied.Condense constant quantities within parentheses, replacing them with a single symbol, for example, 'a', to make the equation look simpler.When an equation contains more than one unknown, use an additional equation to solve the problem.In cases where several unknowns must be determined, keep physical principles in mind and possibly use multiple equations to find the required variable.Condense formulas for chemical structures by using subscripts to denote multiple identical elements, making notation more compact.When you have eliminated all unnecessary terms and used standard conventions for simplification mentioned above, the function is considered to be in its simplest form. It is always good practice to check the answer to see if it is reasonable and does not violate any known principles or constraints.
Which statement is true the graph of y=log(x-4) is the graph of y=log(x) translated 4 units down
The true statement is: The graph of [tex]\(y = \log(x) + 4\)[/tex] is the graph of y = (log(x) translated 4 units up.
Let's analyze each statement:
1. The graph of [tex]\(y - \log(x-4)\)[/tex] is the graph of [tex]\(y - \log(x)\)[/tex] translated 4 units down.
This statement is incorrect. The function [tex]\(y - \log(x-4)\)[/tex] is the result of shifting the graph of [tex]\(y = \log(x)\) 4[/tex] units to the right, not down.
2. The graph of [tex]\(y = \log(x) - 4\)[/tex] is the graph of [tex]\(y = \log(x)\)[/tex] translated 4 units down.
This statement is incorrect. The function [tex]\(y = \log(x) - 4\)[/tex] represents a vertical translation of 4 units down from the graph of [tex]\(y = \log(x)\)[/tex], not left.
3. The graph of [tex]\(y = \log(x) + 4\)[/tex] is the graph of [tex]\(y = \log(x)\)[/tex] translated 4 units up.
This statement is true. Adding a constant term to a function vertically shifts the graph of the function by that amount. So, adding 4 to [tex]\(y = \log(x)\)[/tex] shifts it 4 units up.
4. The graph of [tex]\(y = \log(x+4)\)[/tex] is the graph of [tex]\(y = \log_2(x)\)[/tex] translated 4 units right.
This statement is incorrect. The function [tex]\(y = \log(x+4)\)[/tex] represents a horizontal translation of 4 units to the left from the graph of [tex]\(y = \log(x)\).[/tex]
Therefore, the true statement is: The graph of [tex]\(y = \log(x) + 4\)[/tex] is the graph of y = (log(x) translated 4 units up.
Question
Which statement is true?
The graph of Y - log(x-4) is the graph of y-log,(x) translated 4 units down.
The graph of Y = log: (x)-4 is the graph of y = log. (x) translated 4 units left.
The graph of y = log,(x)+4 is the graph of Y=log.(x) translated 4 units up.
The graph of y = log. (x+4) is the graph of y = log2 (x) translated 4 units right.

Cassandra is trying to think of a good way to keep her financial records. She makes a lot of purchases, using cash, debit cards, and credit cards about equally. When she gets home every day, she tends to be very tired and doesn’t like to do a lot of organized thinking. She tends to lose individual pieces of paper if she doesn’t file them immediately. What might be a good method for Cassandra to use? a. Recording all of her daily expenditures in an organizational computer program. b. Keeping and collecting receipts for everything she buys. c. Tracking and collecting her bank and credit statements every month. d. Carrying a notebook and immediately recording all of her transactions in it.
Answer:
d. Carrying a notebook and immediately recording all of her transactions in it.
Step-by-step explanation:
The correct answer is option D.
What is bank statement?A bank statement is a document that is typically sent by the bank to the account holder every month, summarizing all the transactions of an account during the month.
Bank statements contain bank account information, such as account number and a detailed list of deposits and withdrawals.
Cassandra's best option would probably be carrying a notebook and immediately recording all of her transactions in it.
Since she does not like to do a lot of heavy thinking when she gets home, and tends to lose pieces of paper, this method is ideal because it would allow her to consolidate all her purchase records in one notebook, eliminating the need to carry receipts, and recording them immediately will make it so she can relax when she gets home.
Perhaps once a month, she can compile all of her notebook activity into a computer program and reconcile it to her bank statements.
Hence, the correct option is D.
