If Elon and Jeff work together, they can finish the work in 3 hours. If Jeff works together with Bruce, they
can make this work done in 6 hours. Elon and Bruce can finish this work in 4 hours. How much time would
it take to finish the work if all three worked together? pls helpp
Answer:
2 2/3 hours
Step-by-step explanation:
You want to know the time it would take Elon, Jeff, and Bruce working together, if Elon and Jeff can complete the work in 3 hours, Jeff and Bruce take 6 hours, and Elon and Bruce take 4 hours.
Total of ratesJob completion time problems like this one are more easily understood in terms of rate of completion. If we let e, j, and b represent the rates of job completion in jobs per hour for each of Elon, Jeff, and Bruce, respectively, then the given relations can be written ...
e +j = 1/3
j +b = 1/6
e +b = 1/4
Adding these equations together gives ...
(e +j) +(j +b) +(e +b) = (1/3) +(1/6) +(1/4)
2(e +j +b) = 3/4 . . . . . . . simplify
e + j + b = 3/8 . . . . . . . . divide by 2
The total rate of job completion when Elon, Jeff, and Bruce work together is 3/8 job per hour. The hours it takes them to do one job is the reciprocal of this:
1/(3/8 job/hour) = 8/3 hour/job
It would take Elon, Jeff, and Bruce 2 2/3 hours to complete the work if they worked together.

For this problem, we don't need to know the individual completion times. If we were to figure them we'd find them to be (working alone) ...

Answer: It should be 33.5%
Which has greatest rate help please
The last function having the greatest rate of change.
What is rate of change?
The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another.
Consider the first function,
From this function we get two points (2, 1) and (-2, -1).
To find rate using this points.
Rate = [tex]\frac{y_2-y_1}{x_2-x_1} = \frac{-1-1}{-2-2} = \frac{-2}{-4}=\frac{2}{4} =\frac{1}{2}[/tex]
Consider the second function,
The second function is a vertical line of x = -3.
Since the rate of vertical line is undefined.
Consider the third function,
The third function is a horizontal line y = 4.
Since two points having the same y - value.
Hence, the rate is zero.
Consider, the last function,
From last function we get two points (1, 5) and (-3, -3).
So,
Rate = [tex]\frac{-3-5}{-3-1} = \frac{-8}{-4} = \frac{8}{4} = 2[/tex]
Hence, the last function having the greatest rate.

2.64 to nearest whole number
Answer:
3
Step-by-step explanation:
2.64 rounded to the nearest whole number would be 3. This is because if a number is 5 or greater than 5, it rounds up, but if a number is under 5, it would round down. Since we are looking at the number to the right of the 2 in 2.64, and because we are looking for the nearest whole number, it would round up to 3. 6 is greater than 5, so we automatically know that we round up.
Suppose an individual makes an initial investment of $2,800 in an account that earns 6%, compounded monthly, and makes additional contributions of $100 at the end of each month for a period of 12 years. After these 12 years, this individual wants to make withdrawals at the end of each month for the next 5 years (so that the account balance will be reduced to $0). (Round your answers to the nearest cent.)
(a) How much is in the account after the last deposit is made?
$
(b) How much was deposited?
$
(c) What is the amount of each withdrawal?
$
(d) What is the total amount withdrawn?
$
a) The total amount in the account after the last deposit is $26755.96.
b) A total of $16900 was deposited.
c) Amount of each withdrawal is $517.
d) The total amount withdrawn is $31020.
What is future value?The worth of a present asset at some point in the future based on an estimated rate of growth is known as future value (FV). For investors and financial planners, the future value is crucial because they use it to predict how much an investment made now will be worth in the future.
FV of a single deposit of $ 2800 can be computed as
FV₁ = PV(1+r)ⁿ
PV = $ 2800
r = 6% = 0.06/12
r = 0.005
n= number of periods
= 12 yr × 12 months = 144
FV₁ = 2800 (1 + 0.005)¹⁴⁴
= 2800 (1.005)¹⁴⁴
= 2800(2.0507)
= 5741.96
The FV of monthly deposits can be computed using the formula for the FV of the annuity:
FV₂ = C x [(1+r) n -1/r]
Periodic cash deposit, C = $100
So,
FV = 100 × [((1.055)¹⁴⁴ - 1)/0.005]
= 100 × [(2.0507 - 1)/0.005]
= 100 × [1.0507/0.005]
= 100 × 210.14
= $21014
The total future value of the account is given by
= $5741.96 + $21014
= $26755.96
b) Total deposit = Initial investment amount + amount of monthly deposits
= 2800 + (100 × 144)
= 2800 +14400
= 16900
c) Formula for PV of an annuity can be used to compute monthly withdrawals as:
PV = A x [1-(1+r)⁻ⁿ/r]
So, A = PV/[1-(1+r)⁻ⁿ/r]
PV = $26755.96
n= number of periods = 5 × 12 = 60
r = 0.005 per month
A = 26755.96/ [1- (1+0.005)⁻⁶⁰/0.005]
A = 26755.96/ [1- (1.005)⁻⁶⁰/0.005]
A = 26755.96/ [1- (0.7413)/0.005]
= 26755.96/ [0.2587/0.005]
= 26755.96/(51.74)
= 517.12
So, the amount of each withdrawal for five years is $517.
d) Total amount withdrawn is
= number of withdrawals × amount of each withdrawal
= 60 × 517
=31020

3. Two of the vertices of an equilateral triangle are (0, -a)
and (0, a). The third vertex is on the x-axis to the right of
the origin. Name the coordinates of the third vertex.
The third coordinate of the equilateral triangle is [tex](\sqrt3a,0)[/tex]. Ir can be obtained by distance formula.
What is distance formula?
It gives the distance between two coordinates.
Distance formula is given by the following expression:
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Consider the third cordinate is (x,0) and x is positive because it is on tight side on the x axis.
Now, since the triangle is equilateral hence, the distance of (x,0) from (0, -a) and (0, a) should be equal to distance between (0, -a) and (0, a).
Now, caculate the distance between (0,-a) and (0, a).[tex]\sqrt{(0-0)^2+(-a-a)^2}=2a[/tex]
Now, distance between (x,0) and (0, a) should be 2a.
[tex]\sqrt{(x-0)^2+(0-a)^2}=2a\\\sqrt{x^2+a^2}=2a[/tex]
Now, square on both the sides.
[tex]x^2+a^2=4a^2\\x^2=3a^2\\x=\sqrt3a[/tex]and [tex]-\sqrt3a[/tex]
But the negative value of x is not possible because the coordinate lies on the right side.

A = 126 ft²
x+2
x-3
The x value is 12, length is 14 feet and breath is 9 feet when the area of rectangle is 126 square feet.
Given that,
The rectangle has a surface area of 126 square feet.
The length is x+2 and the breath is x-3.
We have to find the x value, length and breath.
We know that,
The area of the rectangle is length × breath.
126=(x+2)(x-3)
126= x²-3x+2x-6
126= x²-x-6
x²-x-6-126=0
x²-x-132=0
x²-12x+11x-132=0
x(x-12)+11(x-12)=0
(x-12)(x+11)=0
x-12=0 or x+11=0
x=12 or x=-11
We take the x as positive so its 12.
Length is x+2=12+2=14
Breath is x-3=12-3=9
Therefore, The x value is 12, length is 14 feet and breath is 9 feet when the area of rectangle is 126 square feet.

is going to invest $820 and leave it in an account for 19 years. Assuming the interest is compounded quarterly, what interest rate, to the nearest tenth of a percent, would be required in order for John to end up with $1,830?
The rate of interest for an amount which is compounded quarterly is 4.25%
Given,
The principal amount invested by Oliver, P = $820
The time period of the investment, t = 19 years
The interest is compounded quarterly, n = 4
The amount after 19 years, A = $1830
The compound interest formula;
A = [tex]P (1+\frac{r}{n} )^{nt}[/tex]
We have to find the rate of interest;
For that;
A = [tex]P (1+\frac{r}{n} )^{nt}[/tex]
1830 = 820 [tex](1+\frac{r}{4} )^{76}[/tex]
1830/820 = [tex](1+\frac{r}{4} )^{76}[/tex]
₇₆√1830/820 = 1 + r/4
