It takes you 8 hours to dig a hole. It would take you and your brother 5 hours to dig that same hile together. If your brother was to dig the hole by himself it would take him how many hours?
Answer:
40/3 hrs = 13.3 hrs
Step-by-step explanation:
Let me = K , my brother = P
K digs a hole in 8 hrs
K in 1 hr digs 1/8 of a hole
K + P dig a hole in 5 hrs
K + P in 1 hr dig 1/5
Let the portion of the hole Plan digs in 1 hr be x
1/8 + x = 1/5
x = 3/40
3/40 of the hole is dug by P in 1 hr
1 of the hole is dug by P in 40/3 hrs
= 40/3 hrs
=13.3 hrs
My brother alone will take 13 hours and 20 minutes to dig the same hole.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Work is basically the time duration of any task which you have done.
Given that,
I take 8 hours to dig a hole
8 hours of my → 1 work
1 hour of my → 1/8 part of the work
My Brother and I take 5 hours,
5 hours of combined → 1 work
1 hour of combined → 1/5 part of work
Let's say my brother alone takes T time to dig the hole,
T hour of brother → 1 work
1 hour of brother → 1/T part of work
Now,
1 hour of my work + 1 hour of my brother's work = 1 hour of our combined work
1/8 + 1/T = 1/5
1/T = 3/40
T = 13.333 = 13 hour and 20 minutes.
Hence "My brother alone will take 13 hours and 20 minutes to dig the same hole".

Find the area bounded by r=sin(θ)+cos(θ),0≤θ≤π/2
The area bounded by the polar curve r = sin(θ) + cos(θ), where θ ranges from 0 to π/2, is equal to 1. The first paragraph provides the summary of the answer.
To find the area bounded by the polar curve, we can integrate the expression for the area element, which is given by 1/2 r^2 dθ.
In this case, the polar curve is r = sin(θ) + cos(θ), and we want to find the area for 0 ≤ θ ≤ π/2.
We can rewrite the polar curve as r^2 = (sin(θ) + cos(θ))^2.
Expanding and simplifying, we have r^2 = sin^2(θ) + 2sin(θ)cos(θ) + cos^2(θ).
Using the trigonometric identity sin^2(θ) + cos^2(θ) = 1, we can simplify the expression to r^2 = 1 + sin(2θ).
Now we can integrate the area element: A = (1/2) ∫[0,π/2] (1 + sin(2θ)) dθ.
Integrating, we get A = (1/2) [θ - (1/2)cos(2θ)] from 0 to π/2.
Evaluating the integral limits, we have A = (1/2) [(π/2) - (1/2)cos(π)] - (1/2) [(0) - (1/2)cos(0)].
Simplifying, A = (1/2) [(π/2) + (1/2)].
Therefore, the area bounded by the polar curve r = sin(θ) + cos(θ), where θ ranges from 0 to π/2, is equal to 1.

Olivia is considering two phone plans. Plan A charges $20 per month, plus $0.05 per minute. Plan B charges $15 per month plus $0.10 per minute. How many minutes can Olivia talk so that both plans will cost the same amount? (Hint: Create an equation for each plan where y is the total cost and x is the minutes and then find the solution to the system of equations.)
Step-by-step explanation: Answer is 10
For this type of problem, we need to create a slope intercept equation for both.
Let's start by making one for plan a. We know that there is 20 dollars per month, this is the y intercept. Now, although it says per month which can change by x, the problem is mainly asking for minutes.
Remember, a slope intercept equation is
y=mx+b
M is the slope, and x is multiplied to the slope. The slope for an example can be used for this, adam eats 5 apples per day or x, how many apples can he eat in 5 days? We are wanting to know how many he can eat in 5 days, so we of course would multiply 5 by 5. This is basically a slope equation.
So, for plan a, we have y=0.05x+20 where x is minutes
For plan b, we should get
y=0.10x+15 where x is also minutes. The problem is asking use to find which value that we plug in will make both plan a and b correct. Basically, the value we find is x, so we solve for x by setting the two equations equal.
0.05x+20=.10x+15 Use inverse operations
20=.05x+15
5=.05x
x=10
We know if we plug in 10 for x, both would equal the same or 21 dollars.
Consider an angle, and a circle centered at the angle's vertex. The circle's radius is 6 cm long and the angle subtends an arc that is 15.6 cm long. a. What is the angle's measure in radians? radians Preview b. A second circle is centered at the angle's vertex, and the circle's radius is 12 cm long. The subtended arc is how long in cm? (Draw a diagram to help you!) cm
The subtended arc for the second circle is 31.2 cm long.
Given a circle with a radius of 6 cm and a subtended arc of 15.6 cm, we can find the angle's measure in radians using the formula: angle (in radians) = arc length/radius. Plugging in the values, we get angle = 15.6 cm / 6 cm = 2.6 radians.
For the second circle with a radius of 12 cm, we can find the subtended arc length by rearranging the formula: arc length = angle (in radians) * radius. Using the angle of 2.6 radians, we get arc length = 2.6 radians * 12 cm = 31.2 cm. Therefore, the subtended arc for the second circle is 31.2 cm long.

how many numbers less than 2017 are both the sum of two consecutive positive integers, and the sum of five consecutive positive integers?
201 numbers are less than 2017
If and only if it is odd, a number is the sum of two successive integers.
Only if it is a multiple of 5 is a number considered to be the sum of 5 consecutive integers. If you have any doubts, remember that the product of five consecutive integers equals five times the integer in the middle (this remains true if instead of 5 you put in any odd positive integer).
Consequently, you are seeking odd multiples of 5 below 2017. There are 403 multiples of 5 immediately below 2017, or 2015/5. Of those, 202 are odd.

To calculate the Taylor polynomials T2 and T3 centered at a = 0 for the function f(x) = 13 tan(x), we need to find the first few derivatives of f(x) and then evaluate them at a = 0.
1. Find the first few derivatives:
f'(x) = 13 sec²(x)
f''(x) = 26 sec²(x)tan(x)
f'''(x) = 26 sec²(x)(tan^2(x) + 2)
2. Evaluate derivatives at a = 0:
f(0) = 13 tan(0) = 0
f'(0) = 13 sec²(0) = 13
f''(0) = 26 sec²(0)tan(0) = 0
f'''(0) = 26 sec²(0)(tan²(0) + 2) = 52
3. Form the Taylor polynomials:
T2(x) = f(0) + f'(0)x + (1/2)f''(0)x² = 0 + 13x + 0 = 13x
T3(x) = T2(x) + (1/6)f'''(0)x³ = 13x + (1/6)(52)x³ = 13x + (26/3)x³

you are taking out candies one by one from a jar that has 10 red candies, 20 blue candies, and 30 green candies in it. what is the probability that there are at least 1 blue candy and 1 green candy left in the jar when you have taken out all the red candies?
The required probability that there are at least 1 blue candy and 1 green candy left in the jar when you have taken out all the red candies is 7/12 .
Probability is defined as the ratio of total numbers of outcomes of an event to the favouable outcomes of an event.
We have , Red candies in the jar = 10
green canides in the jar = 30
blue candies in the jar = 20
total number of candies in jar = 60 i.e total number of outcomes = 60
The Probability that the last of sixty candies drawn is one of thirty green candies = 30/60 = 1/2
Ignoring green canides, probability that the last of the thirty other candies drawn is one of twenty blue = 20/30 = 2/3
The Probability that the last of sixty candies drawn is one of twenty blue candies = 20/60 = 1/3
The Probability that the last of sixty candies drawn is not one of twenty blue candies = 1 - 1/3
= 2/3
Probability that last draw would be blue and the last not blue would be green = 20/60 × 30/40
= 1/4 ----(1)
Probability that last draw would be green and the last not green would be blue = 30/60× 20/30

A bacteria culture starts with 500 bacteria and after 3 hours there are 8,000 bacteria. Find (a) an expression for the number of bacteria after t hours, (b) the number of bacteria present after 4 hours, and (c) the time when the population will reach 30,000.
a. The expression for the number of bacteria after t hours is given by N(t) = 500 x \(2^{t/3}\). b. The number of bacteria present after 4 hours is N(4) = 500 x \(2^{4/3}\) = 5,000. c. And the time when the population will reach 30,000 bacteria is t = 3 + 3×log2(30), which is approximately 16.94 hours.
we can use the given information to set up an exponential growth model for the bacteria population. We know that the initial population is 500 and that after 3 hours, the population has grown to 8,000. Using the formula for exponential growth, N(t) = N0 x \(e^{kt}\), where N0 is the initial population, k is the growth rate, and t is time, we can solve for k and then use it to find N(t) for any time t.
First, we can use the information given to find k. We know that N(0) = 500 and N(3) = 8,000, so we can set up the following equation: 8,000 = 500 x \(e^{3k}\)). Solving for k, we get k = ln(16)/3.
Using this value of k, we can find N(t) for any time t using the formula N(t) = 500 x \(e^{((ln(16)/3) t) }\). Simplifying, we get N(t) = 500 x 2^(t/3), which gives us the expression for the number of bacteria after t hours.
To find the number of bacteria present after 4 hours, we simply plug t = 4 into the expression for N(t) and get N(4) = 500 x \(2^{4/3}\) = 5,000.
Finally, to find the time when the population will reach 30,000 bacteria, we set N(t) = 30,000 and solve for t. This gives us 30,000 = 500 x 2^(t/3), which simplifies to \(2^{t/3}\) = 60. Solving for t, we get t = 3 + 3×log2(30), which is approximately 16.94 hours.
