I don't understand how you substituted the equation of this question noted the length,d m,of a rectangular field is 40m greater than the width. The perimeter of the field is 400m . Kindly simplify
The width of the rectangular field is 80 meters and the length is 120 meters for the given perimeter 400m.
What is the perimeter?Perimeter is a mathematical term that refers to the total distance around the outside of a closed two-dimensional shape. It is the sum of the lengths of all the sides of the shape.
According to the given information:
Let's break down the information given in the question:
Length of the rectangular field is 40m greater than the width.
The perimeter of the field is 400m.
Let's denote the width of the rectangular field as 'w' meters. According to the first information, the length of the field would be 'w + 40' meters, as it is 40m greater than the width.
Now, let's use the formula for the perimeter of a rectangle, which is given by:
Perimeter = 2 * (Length + Width)
Substituting the values we have:
Perimeter = 2 * (w + 40 + w)
Perimeter = 2 * (2w + 40)
Since the given perimeter is 400m, we can set up the equation:
400 = 2 * (2w + 40)
Now we can solve for 'w' by dividing both sides of the equation by 2:
400/2 = 2w + 40
200 = 2w + 40
Next, we subtract 40 from both sides of the equation to isolate the term with 'w':
200 - 40 = 2w
160 = 2w
Finally, we divide both sides of the equation by 2 to solve for 'w':
160/2 = w
80 = w
So, the width of the rectangular field is 80 meters. And since the length is 40 meters greater than the width, the length would be:
Length = Width + 40 = 80 + 40 = 120 meters.
So, the width of the rectangular field is 80 meters and the length is 120 meters.

An object launched directly in the air at a speed of 24 feet per second from a platform located 16 feet above the ground. The position of the object can be modeled using the function f(t)=-16t^2+24t+16
The maximum height that the object will reach is 40 feet.
How to find the maximum height that the object will reach?For any quadratic equation of the form, f(t) = at² + bt + c,
where a, b and c are constants
The maximum value of f(t) is give by the formula:
f(t) = c - (b²/4a)
Since the position of the object can be modeled using the function:
f(t) = -16t² + 24t + 16
where a = -16, b = 24 and c = 16
Thus, the maximum height will be:
maximum height = 16 - (24² / 4(-6))
maximum height = 16 - 576/(-24)
maximum height = 16 + 24
maximum height = 40 feet

A furniture company makes bar stools, tables, and chairs. Each bar stool requires 1 hour of labor, 8 feet of wood, and 0.2 gallons of stain. Each chair requires 4 hours of labor, 16 feet of wood, and 0.4 gallons of stain. Each table requires 2 hours of labor, 32 feet of wood, and 0.5 gallons of stain. Each week, the company has 700 hours of labor, 3360 feet of wood, and 60 gallons of stain. The company makes $10 in profit per bar stool, $25 in profit per chair, and $35 in profit per table. In order to maximize their profit, the furniture company should make
In the given problem, the furniture company should produce 300 bar stools and 50 chairs to maximize their profit, and should not produce any tables.
How to solve the Problem?To maximize profit, the furniture company needs to determine how many units of each product (bar stools, chairs, and tables) they should produce. Let's use x, y, and z to represent the number of bar stools, chairs, and tables respectively.
The objective function to maximize profit is:
Profit = 10x + 25y + 35z
The company has constraints on the amount of labor, wood, and stain available. These constraints can be expressed as follows:
Labor: 1x + 4y + 2z ≤ 700 (the company has 700 hours of labor available each week)
Wood: 8x + 16y + 32z ≤ 3360 (the company has 3360 feet of wood available each week)
Stain: 0.2x + 0.4y + 0.5z ≤ 60 (the company has 60 gallons of stain available each week)
Also, since we cannot produce negative units of any product, we must add the constraint that x, y, and z are all non-negative.
x ≥ 0, y ≥ 0, z ≥ 0
We can now use linear programming techniques to solve this problem. One possible method is the simplex method, which involves converting the problem into an augmented matrix and applying row operations until we obtain the optimal solution.
The optimal solution is:
x = 300 (produce 300 bar stools)
y = 50 (produce 50 chairs)
z = 0 (do not produce any tables)
The maximum profit that the company can earn is:
Profit = 10x + 25y + 35z = 10(300) + 25(50) + 35(0) = $3,250
Therefore, the furniture company should produce 300 bar stools and 50 chairs to maximize their profit, and should not produce any tables.

Step-by-step explanation:
You are on a fishing boat that leaves its pier and heads east. After traveling for 29 miles, there is a report warning of rough seas directly south. The captain turns the boat and follows a bearing of S35°W for 14.6 miles.
a. At this time, how far are you from the boat's pier?
b. What bearing could the boat have originally taken to arrive at this spot?
a. The boat is currently 60.5 miles from its pier.
b. The boat could have originally taken a bearing of either N45°E or S45°W to arrive at the current spot.
a.How to determine the distance from the boat's pier?
To determine the distance from the boat's pier, we can use the Pythagorean theorem since we have a right triangle formed by the boat's original position, the current position, and the distance traveled to reach the current position.
Let's call the distance from the boat's pier to the current position "d", and let's call the distance traveled after the turn "x".
Using trigonometry, we can see that:
sin(35°) = x/d
Rearranging this equation, we get:
x = d×sin(35°)
Now we can use the Pythagorean theorem to solve for "d":
d² = 29²+ (d×sin(35°))²
d² = 841 + 0.77d²
0.23d² = 841
d² = 3661.74
d = 60.5 miles (rounded to one decimal place)
Therefore, the boat is currently 60.5 miles from its pier.
b. How to determine the original bearing?
To determine the original bearing, we can use trigonometry again. Let's call the original bearing "θ". Then we have,
cos(θ) = 29/d
Rearranging this equation,
d = 29/cos(θ)
Now we can substitute this expression for "d" into the equation we used to solve for "x" earlier:
x = d×sin(35°)
x = (29/cos(θ))×sin(35°)
We know that after traveling this distance, the boat is currently 14.6 miles away from its original position. So we can set up another equation:
cos(θ) = 14.6/(29/cos(θ))
Simplifying, we get:
cos²(θ) = 0.5
Taking the inverse cosine of both sides,
θ = 45° or θ = 315°
Therefore, the boat could have originally taken a bearing of either N45°E or S45°W to arrive at the current spot.

The measure of angle or arc FDG is 285°.
What is an arc of circle?A circle's circumference may be divided up into arcs. It is described as the curved line that divides a circle into segments by joining two points on its circumference. An arc's length is inversely proportional to the angle it forms at the circle's centre.
The length of the arc increases with increasing central angle, and vice versa. In geometry, trigonometry, and physics, arcs are frequently employed to represent and compute measurements of circles and circular objects.
For given problem,
mGC = 105° and
mFDG= 360° - mGF (∵ Total arc or angle of circle is 360°)
(As, mGF=mFC-mGC)
= 360°-(180°-mGC) (Assuming FC is a diameter making mFC=180°)
= 360°-(180°-105°) (∵mGC = 105°)

12. A new software package is expected to improve productivity at X company. However, because of training and implementation costs, savings are not expected to occur until the third year of operation. At that time, savings of $10,000 are expected, increasing by $1,000 per year for the following five years. After this time (eight years from implementation), the software will be abandoned with no scrap value. How much is the software worth today, at 15% interest?
Okay, here are the steps to solve this problem:
1) Savings start in year 3 at $10,000.
2) Savings increase by $1,000 each year for 5 years, so years 4-8 savings are $11,000, $12,000, $13,000, $14,000, $15,000.
3) There are 8 years of savings total.
4) Interest rate is 15%.
To calculate the present value at year 0 (today), we use the following formula:
PV = FV / (1 + r)^n
Where FV is the future value, r is the interest rate, and n is the number of years.
So for year 3 savings of $10,000:
PV = $10,000 / (1 + 0.15)^3 = $8,562
For year 4 savings of $11,000:
PV = $11,000 / (1 + 0.15)^4 = $8,948
And so on...
Adding up the present values for years 3 to 8:
$8,562 + $8,948 + $9,371 + $9,820 + $10,298 + $10,796 + $11,310 + $11,842 = $80,847
Therefore, the total present value of the 8 years of savings is $80,847.
So the software is worth $80,847 today at a 15% interest rate.

P(No Tardiness) = P(No Tardiness | Car) * P(Car) + P(No Tardiness | Bicycle) * P(Bicycle)
P(No Tardiness) = (0.88 * 0.35) + (0.75 * 0.65) = 0.308 + 0.4875 = 0.7955
The probability that Anya will not be late is 0.7955.

Find the radius of a cylinder or volume 45 cm3 and length of 4 cm
Using the given volume and the length of the cylinder we know that the radius is 1.89 cm approximately.
What is a cylinder?A cylinder is one of the most basic curvilinear geometric shapes and has traditionally been solid in three dimensions.
In elementary geometry, it is regarded as a prism with a circle as its basis.
A cylinder can instead be described as an infinitely curved surface in a number of modern domains of geometry and topology.
So, the volume of the cylinder is 45 cm³.
The length is 4 cm.
Now, the formula for volume is: V=πr²h
Insert values and calculate r as follows:
V=πr²h
45=3.14r²4
45=12.56r²
45/12.56=r²
3.58 = r²
1.89 = r
Therefore, using the given volume and the length of the cylinder we know that the radius is 1.89 cm approximately.

ways to select the 7 math help websites
Answer:
Step-by-step explanation:
If the order you select them is important
nmber of ways = 9! / (9-7)!
= (9*8*7*6*5*4*3*2*1) / (2*1)
= 9*8*7*6*5*4*3
= 181,440.
If the order does not matter:
nmber of ways = 9! / ((9-7)! * 7!)
= 9*8 / 2*1
= 36.
Over time, the number of organisms in a population increases exponentially. The table below shows the approximate number of organisms after y years.
The environment in which the organism lives can support at most 600 organisms. Assuming the trend continues, after how many years will the environment no longer be able to support the population?

After 12 years, the environment can no longer support the population growth. (option a).
Population growth is a fundamental concept in ecology and biology. It refers to the increase in the number of organisms in a population over time.
The carrying capacity is the maximum number of individuals of a particular species that can be supported by the environment without degrading it. In this case, the carrying capacity of the environment is 600 organisms. When the population reaches this limit, the environment can no longer support the population, and the growth rate slows down until it reaches equilibrium.
The table provides the approximate number of organisms after y years. To determine when the environment can no longer support the population, we need to find the year when the population exceeds the carrying capacity of the environment. In other words, we need to find the year when the population reaches or exceeds 600 organisms.
Looking at the table, we can see that the population reaches 600 organisms in the year 12.
Hence the correct option is (a).

How to determine the number of years?
The proper representation of the table is given as:
y 1 2 3 4
n 55 60 67 75
An exponential function is represented as:
[tex]n=ab^y[/tex]
Where:
a represents the [tex]initial[/tex] [tex]value[/tex]b represents the [tex]rate[/tex]Next, we determine the function equation using a statistical calculator.
From the statistical calculator, we have:
[tex]a=49.19[/tex] [tex]and[/tex] [tex]b=1.11[/tex]
Substitute these values in [tex]n=ab^y[/tex] .
So, we have:
[tex]n=49.19*1.11^y[/tex]
From the question, the maximum is 600.
So, we have:
[tex]49.19*1.11^y=600[/tex]
Divide both sides by 49.19
[tex]1.11^y=12.20[/tex]
Take the logarithm of both sides
[tex]y log(1.11) = log(12.20)[/tex]
Divide both sides by log(1.11)
[tex]y=23.97[/tex]
Approximate
[tex]y=24[/tex]
Hence, the environment will no longer be able to support the population after a period of 24 years.
12(x-20)=-48 for 7th grade math equation algebra
Answer: 16
Step-by-step explanation:
1. Distribute the 12 to the x variable and the constant.
You will get 12x - 240 = -48
2. -48 + 240 = 192. You now have 12x = 192
3. solve for x. x = 192/12 -> x = 16
Elizabeth brought a box of donuts to share. There are two-dozen (24) donuts in the box, all identical in size,
shape, and color. Five are jelly-filled, 9 are lemon-filled, and 10 are custard-filled. You randomly select
one donut, eat it, and select another donut. Find the probability of selecting a lemon-filled donut followed by a
custard-filled donut.
(Type an integer or a simplified fraction.)
The probability of selecting a lemon-filled donut followed by a custard-filled donut is given as follows:
p = 15/92
How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.
The probability of each event is given as follows:
First donut is lemon: 9/24.Second donut is custard: 10/23. -> 23 total outcomes as one has been eaten.Hence the probability is obtained as follows:
p = 9/24 x 10/23
p = 9/12 x 5/23
p = 3/4 x 5/23
p = 15/92

The probability that a student had blue eyes and wore glasses is 4% or 0.04.
B. The probability that a student's eye color is brown given that the student wears glasses is 42.9% or 0.429.
What is the probability?To find the probability of blue-eyed glasses-wearers, when you look where "Blue" intersects "Yes" in the table. The relative frequency is 0.04, or 4%, hence the probability of a student having blue eyes and wearing glasses 4%.
To find the probability that a student's eye color is brown since the fact is: that the student wears glasses, it can be calculated as:
P(A|B) = P(A and B)/P(B)
P(Brown and Yes) = 0.12
P(Yes) = 0.04 + 0.12 + 0.08 + 0.04
= 0.28
Hence, the probability that a student's eye color is brown since they wear glasses are:
P(Brown | Yes) = P(Brown and Yes) / P(Yes)
= 0.12 / 0.28
= 0.429 or 42.9%
So we can say that, Blank 1 is "0.04" while Blank 2 is "42.9%".
