look at the Pentagonal figure with the dimensions shown in the diagram what is area of the figure ?.
Answers
Area of Pentagonal figure = 368 feet²
Explanation:To find the area of the Pentagonal figure, we need to divide the shape into figures we can easily find their areas.
The Pentagonal figure comprise of a triangle and a rectangle.
Area Pentagonal figure = Area of triangle + Area of rectangle
Area of triangle = 1/2 base × height
base = 5 ft, height = 12 ft
Area = 1/2 × 5 × 12 = 30
Area of triangle = 30 feet²
Area of rectangle = length × width
length = 26ft, with = 13 ft
Area of rectangle = 26 × 13
Area of rectangle = 338 feet²
Area of Pentagonal figure = 30 feet² + 338 feet²
Area of Pentagonal figure = 368 feet²
You want to be able to withdraw $30,000 from your account each year for 30 years after you retire.You expect to retire in 20 years.If your account earns 6% interest, how much will you need to deposit each year until retirement to achieve your retirementgoals?$Round your answer to the nearest cent.Question Help: Video Post to forum
Answers
In this case we are making deposits each year in out account. This will be compounded at a 6% interest.
After 20 years of working and making deposits, the principal accumulated has to be able to give $30,000 per year for 30 years.
We can start with the principal. We assume that during retirement, the account yield 6% interest from the capital still in the account.
Then, we can calculate this principal as the present value of an annuity with payments PMT = $30,000, rate of interest r = 0.06 and n = 30 years.
The calculation is:
[tex]\begin{gathered} PV=PMT\cdot\frac{1-(1+r)^{-n}}{r} \\ PV=30000\cdot\frac{1-(1.06)^{-30}}{0.06} \\ PV\approx30000\cdot\frac{1-0.17411}{0.06} \\ PV\approx30000\cdot\frac{0.82589}{0.06} \\ PV\approx30000\cdot13.7648 \\ PV\approx412944.93 \end{gathered}[/tex]Now we know the amount of capital that has to be accumulated with the deposits.
This value is the future value of an annuity of n = 20 years at a rate r = 0.06.
But now, we need to calculate the yearly deposit D.
We can calculate it as:
[tex]\begin{gathered} D=\frac{FV\cdot r}{(1+r)^n-1} \\ D=\frac{412944.93\cdot0.06}{(1.06)^{20}-1} \\ D\approx\frac{24776.70}{3.207-1} \\ D\approx\frac{24776.70}{2.207} \\ D\approx11225.73 \end{gathered}[/tex]Answer: the yearly deposit has to be $11,225.73.

We are given the following function that models the temperature T as a function of the latitude L:
T = - 0.68 L + 89.5
We see that the temperature is in fact a linear function of slope -0.68 degrees/latitude.
Since the latitude of the Equator is 0 degrees, then, the equation tells us that the temperature at the Equator is:
T = - 0.68 (0) + 89.5 = 89.5 degrees of annual temperature. But this is NOT related to the slope.
The other two statements (B and C) are not correct,
The last statement D is correct, since for every degree increase in latitude, there is an annual decrease of temperature by 0.68 degrees, and this is what the slope expresses.

We want to fill a basin 3m wide, 5m long and 1m deep using atap with a flow rate of 2m^3 / h.1 °) How long does it take to fill the basin?2 °) Express the flow rate of the tap in L / min. We will round to the hundredth.
Answers
Part 1
First we have to find the volume of the basin. We must multiply the dimensions to do so.
V= (3)(5)(1) m^3
V= 15 m^3
If the tap has a flow of 2 m^3 per hour it means that it would take 7.5 hours to fill the basin. ( Dividing 15 m^3 by 2 m^3/h)
The answer of the first part is 7.5 hours.
Part 2
To express the flow rate in L/min we would have to multiply 2m^3 by 1000 ( Since 1000 L= 1 m^3) and then divide the result by 60 minutes ( Since 1 hour has 60 minutes). Doing so, we have:
[tex]2\frac{m^3}{h}\cdot\frac{1000\text{ L}}{1m^3}\cdot\frac{1h}{60\text{ min}}=33.33\text{ L/min}[/tex]The answer of part 2 is 33.33 L/min (Rounding to the hundredth).
Using the indicated slopes of lines and L1 and L2, determine whether the lines are parallel, perpendicular, or neither.Assume that the lines are not the same. M1= 4/7, M₂= -7/4 Choose the correct answer below. a)Parallel b)Perpendicular c)Neither
Answers
the lines are perpendicular (option B)
Explanation:
For L1 and L2 to be parallel, their slopes must be equal
That is: M1 = M₂
The given slope: M1= 4/7, M₂= -7/4
Hence, they are not parallel as they are not equal
For the lines to be perpendicular, one of the the slope will be the negative reciprocal of the other one:
M1 = 4/7
Reciprocal of M1 = 7/4
Reciprocal means inverse. For
Negative Reciprocal of M1 = -7/4
This is equal to M₂
Hence, the lines are perpendicular (option B)

The total probability that 2 randomly selected dogs are yellow Labradors without replacement is 3/13.
What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.So, the probability that the randomly selected dogs are yellow Labradors:
Probability formula: P(E) = Favourable events/Total eventsProbability in 1st selection:
P(E) = Favourable events/Total eventsP(E) = 7/14P(E) = 1/2Probability in 2nd selection: Without replacement
P(E) = Favourable events/Total eventsP(E) = 6/13Total Probability: 1/2 × 6/13 = 6/26 ⇒ 3/13
Therefore, the total probability that 2 randomly selected dogs are yellow Labradors without replacement is 3/13.

Let y represent the rental cost for each video game.
From the information given,

3x + 8y = 58
Also,
he rented 5 movies and 2 video games for a total of $23. The equation representing this scenario would be
5x + 2y = 23
We would solve both equations by applying the method of elimination. To elimimate x, we ould multiply the first equation by 5 and the second equation by 3. We have
15x + 40y = 290
15x + 6y = 69
Subtracting the second equation from the first, we have
15x - 15x + 40y - 6y = 290 - 69
34y = 221
Dividing both sides by 34,
34y/34 = 221/34
y = 6.5
Substituting y = 6.5 into 5x + 2y = 23, we have
5x + 2(6.5) = 23
5x - 13 = 23
Adding 13 to both sides, we have
5x - 13 + 13 = 23 - 13
5x = 10
x = 10/5

Altogether, you will pay $631.24 if the interest is compounded at the end of every year for 4 years or $620 if it is based on simple interest.
What is the difference between compound interest and simple interest?Compound interest accumulates the interest and adds it to the principal for calculating subsequent interest.
On the other hand, simple interest does not accumulate the interest to add to the principal before computing the next year's.
N (# of periods) = 4 years
I/Y (Interest per year) = 6%
PV (Present Value) = $500
PMT (Periodic Payment) = $0
Results:
FV = $631.24
Total Interest = $131.24
Simple interest = $120 ($500 x 6% x 4)
Future value at simple interest = $620 ($500 + $120)
Thus, depending on how interest is calculated, you will repay between $620 and $631.24.
