It takes 12 men 5 days to complete a job
Work out how many days it would take 3 men to complete the same job
Answer: 8
Step-by-step explanation: i took the test
1.25 days would be taken for 3 men to complete the same job.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that 12 men 5 days to complete a job
We have to find for how many days three men can complete the same job.
Let x be the time taken by 3 men to complete the job.
Formulate a proportional equation.
12/5=3/x
Apply cross multiplication
12x=15
Divide both sides by 12
x=15/12
both 15 and 12 are multiples of 3
x=5/4
x=1.25
Hence, 1.25 days would be taken for 3 men to complete the same job.

Savannah loves to talk on her cell phone. She has $100 in her budget to pay this month’s cell phone bill. Her cell phone plan is $20 per month plus $0.10 per minute of usage. If x represents the minutes of usage, which equation best represents the word problem?
A. 100+20=.10x
B. 100+.10x=20
C. 20 +.10x=100
D. 20-.10x= 100
Answer: C. best fits the word problem.
Step-by-step explanation:
The reason C. best fits is because the bare minimum $20 she has to pay plus .10 times whatever amount of minute's she spends talking has to equal $100 for her to stay in budget. A good example would be say she spends 800 minutes in total on her phone. 0.10 times 800 is 80. So in this hypothetical situation, it would be 20 + 80 = 100.
Quadrilateral KLMN was reflected across y = -2. Find M.
Answer:
The picture states it is reflected across y = -x, which is different to y = -2 (maybe the question before's answer was 2? However this question is not linked)
If it is y = -x, the answer is (1, 1)
If it is y = -2, which I doubt, the answer is (-1, -3)
The circumference of a circle is 10 inches. What is its area in square inches?
Answer:
7.96 square inches.
Step-by-step explanation:
Area of a circle given a circumference is given by formula:
[tex]A = \frac{C^{2}}{4\pi}[/tex]
So substituting into equation we have: [tex]C= 10[/tex].
Therefore [tex]A = 10^{2}/4\pi = 100/4\pi=25/\pi =7.96[/tex] square inches.
The area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The circumference of a circle is 10 inches.
As we know the circumference of a circle is given by:
C = 2πr
C is the circumference of the circle.
r is the radius of the circle.
10 = 2πr
r = 5/π inches
As we know,
The area of the circle is given by:
A = πr²
Here, A represents the area of the circle.
Plug the value of the radius r in the above formula:
A = π(5/π)²
A = 25/π square inches
Take π = 3.14
A = 25/3.14
A = 7.96 sqaure inches
Thus, the area of the circle is 7.96 square inches if the circumference of a circle is 10 inches.

The cost of an apple was 0.62 cents.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
An equation is a mathematical statement that shows that two mathematical expressions are equal.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
An equation says that two things are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, Bill bought 5 apples Mary bought 2 apples and spent 1.86 for strawberries. both the spent equal amounts, we need to write and solve the equation for the price of apples,
Let the cost of 1 apple = A
Bill bought = 5A apples
Mary bought=2A + 1.86
5A = 2A + 1.86
3A = 1.86
A = 1.86/3
A = 0.62 cents
Hence, the cost of an apple was 0.62 cents.

Jada is planning a kayak trip. She finds an expression for the time, T(s), in hours it takes her to paddle 10 kilometers upstream in terms of s, the speed of the current in kilometers per hour. This is the graph Jada gets if she allows s to take on any value between 0 and 7.5. What would be a more appropriate domain for Jada to use instead?
Answer:
A more appropriate domain would be all real numbers except x = 5.5
Step-by-step explanation:
Given that the domain of a rational function consists of the set of real numbers but excluding those real numbers that results in a zero in the denominator
The given graph of the function has a vertical asymptote at s = 5.5 which indicates a value for which the function is not defined and at x = 5.5, and as such the value (5.5) of the asymptote is not a member of the function's domain
The values of the domain of a function consisting of a reciprocal must exclude does that result in a zero denominator.
The domain of the function that represents Jada's trip is the set of input value the function can take
The appropriate domain is: all real numbers except x = 5.5
From the graph, we can see that:
The x-value starts at negative infinity, and ends near 5.5The x-value then continues near 5.5, and ends at positive infinityThis means that the input of the graph cannot be 5.5
Hence, an appropriate domain would be: [tex]\mathbf{x \ne 5.5}[/tex]
