Bob can do a job in 5 hours while Bill can do the same job in 8. How many hours would it take them, working together, to do this job?
Final answer:
Bob and Bill can complete the job together in approximately 3.08 hours by combining their individual rates of work, which are 1/5 and 1/8 jobs per hour respectively.
Explanation:
The question asks how long it would take Bob and Bill to complete a job if they worked together, with Bob being able to do it in 5 hours and Bill in 8 hours. To solve this, we calculate the rates at which Bob and Bill work and then combine these rates to find their combined rate.
Bob's rate is 1 job per 5 hours, or 1/5 jobs per hour. Bill's rate is 1 job per 8 hours, or 1/8 jobs per hour. When they work together, their combined rate is 1/5 + 1/8 = 8/40 + 5/40 = 13/40 jobs per hour.
To find the total time it takes for them to complete 1 job, we take the reciprocal of their combined rate: 1 / (13/40) = 40/13, which is approximately 3.08 hours.
Combining Bob and Bill's individual rates, it would take them approximately 3.08 hours to complete the job together.
Find out how long it would take Bob and Bill to do the job together:
Calculate individual rates.
Bob's rate: He can complete the job in 5 hours, meaning his rate is 1 job / 5 hours.
Bill's rate: He can complete the job in 8 hours, meaning his rate is 1 job / 8 hours.
Combine rates.
To find their combined rate, we simply add their individual rates: Combined rate = Bob's rate + Bill's rate Combined rate = (1 job / 5 hours) + (1 job / 8 hours)
Calculate combined time.
Now, divide 1 (representing the entire job) by the combined rate to find the total time they take working together: Time together = 1 / Combined rate Time together = 1 / ((1 job / 5 hours) + (1 job / 8 hours))
Simplify and express the answer.
This can be simplified to: Time together = 40 / 13 hours Time together ≈ 3.08 hours
Therefore, it would take Bob and Bill approximately 3.08 hours to complete the job together.

Answer:
A
Step-by-step explanation:
-32
Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
Velocity = Height / Time
The velocity, in feet per second, of the ball after 2 seconds is 24.
Option C is the correct answer.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
h(t) = 56t - 16t²
h(t) is the height after t seconds.
Now,
Velocity = Height / Time
At t = 2,
h(2):
= 56 x 2 - 16 x 4
= 112 - 64
= 48
Now,
Velocity = 48 / 2
Velocity = 24
Thus,
The velocity, in feet per second, of the ball after 2 seconds is 24.
Option C is the correct answer.

If you were a lender, why would employment history or credit reports be important to you?
If I were a lender, the borrower's credit report will be important for me. The credit report should be positive and accurate if a person wants to borrow money from me. Good credit reports generate good credit scores and the higher the credit score, the lower the risk to me or the lender.
Similarly, employment history is a measure to check before lending money. This is because if a person has a good history and is working with good firms and on a regular basis, this develops trust that he will work properly pay off the debt. If a person is not responsible at work place and changes his jobs and cities frequently, then it is not sure if he can pay off the debt.
Banks also check these two things before lending any money. These information about a borrower develops trust among the lenders.
Employment history and credit reports gives an insight of an individual's past financial credibility, hence, they are useful in making a decision on whether to lend such individual and the amount that should be lent.
Employment history gives an account about whether a person is presently employed or not, and it also gives an insight about duration of stay with previous employers. Credit history gives an account into past financial details, the promptness exercised in repayment and if there are any pending debts.Therefore, these information are necessary for adequate decision making about the financial capability and integrity of the borrower.

m∠S
?
Enter your answer in the box.
Answer:- m∠S=78°.
Explanation:-
Given:- Two congruent triangles ΔMNP and ΔQST which are congruent, where m∠M=66° and m∠N=78°.
⇒The corresponding parts of ΔMNP are congruent to the ΔQST .
Therefore, all the corresponding sides of ΔMNP are congruent to the ΔQST and all the corresponding angles of ΔMNP are congruent to the ΔQST such that
MN=QS , NP=ST and MP=QT.
m∠M=m∠Q, m∠P= m∠T and m∠N=m∠S.
Substitute the value of m∠N=78°, we get
m∠S=78°.

b) Imagine that you earned $8,425 in one year. If the government enforces a 15% income tax, how much money would you owe in taxes at the end of the year? Show your work.
Answer:
You would owe $1,263.75 in taxes at the end of the year.
Explanation:
To calculate the amount of income tax owed, you can use the formula:
Tax amount = Income * Tax rate
Given:
Income = $8,425
Tax rate = 15%
Substitute the values into the formula:
Tax amount = $8,425 * 0.15
= $1,263.75
So, you would owe $1,263.75 in taxes at the end of the year.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure
The given transformation is (x, y)-->(x + 2, y -2)
A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.

A right triangle has a hypotenuse of 13 cm and one leg that measures 12 cm. what is the length of the other leg?
The answer is 22.62
Hope this helps :)
The length of the other leg is 5 cm.
To find the length of the other leg of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
Let's denote the length of the other leg as ( x ) cm.
According to the Pythagorean theorem:
[tex]\[ \text{hypotenuse}^2 = \text{leg}_1^2 + \text{leg}_2^2 \][/tex]
Given that the hypotenuse ( c ) is 13 cm, and one leg ( a ) is 12 cm:
[tex]\[ 13^2 = 12^2 + x^2 \][/tex]
[tex]\[ 169 = 144 + x^2 \][/tex]
Now, subtract 144 from both sides:
[tex]\[ x^2 = 169 - 144 \][/tex]
[tex]\[ x^2 = 25 \][/tex]
Taking the square root of both sides:
[tex]\[ x = \sqrt{25} \][/tex]
[tex]\[ x = 5 \][/tex]
Therefore, the length of the other leg is 5 cm.

You reach into a bag of coins and withdraw two coins without replacement. What is the probability you withdrew a nickel and then a dime if the bag held five pennies, ten nickels, and four dimes?
Answer: [tex]\dfrac{20}{171}[/tex]
Step-by-step explanation:
Given : Number of nickels in the bag = 10
Number of dimes in the bag = 4
The total number of coins in the bag =[tex]10+4+5=19[/tex]
The probability of drawing nickel :-
[tex]\text{P(nickel)}=\dfrac{10}{19}[/tex]
Total number coins left = 18
The conditional probability of drawing dime, given that a nickel is already drawn :-
[tex]\text{P(dime}|\text{nickel)}=\dfrac{4}{18}[/tex]
Now, the probability you withdrew a nickel and then a dime is given by :-
[tex]\text{P(dime and nickel)}=\text{P(dime}|\text{nickel)}\times\text{P(nickel)}\\\\=\dfrac{10}{19}\times\dfrac{4}{18}=\dfrac{20}{171}[/tex]
Now, the probability you withdrew a nickel and then a dime [tex]}=\dfrac{20}{171}[/tex]

To find the linear equation of a line passing through two given points, use the formula for the slope of a line to calculate the slope, then substitute this value, along with one of the given points, into the point-slope form of a line and solve for y.
Explanation:The subject of this question is the formulation of a linear equation, specifically a equation of a line passing through two given points (3, -1) and (-2, 5). The formula used to find the slope (m) of a line between two points is: m = (y2 - y1) / (x2 - x1). Use this formula to calculate the slope using these points(m = (5 - (-1)) / (-2 - 3) = -6/5) .
Next, using the point-slope form of a line, y - y1 = m(x - x1), we substitute m with the calculated slope, and (x1, y1) with one of the given points. (Let's use (3, -1), y - (-1) = -6/5(x - 3) simplifying this gives us the answer: y=-6/5x +13/5. Therefore, the correct answer is choice B: y=-6/5x +13/5.
