Answer: 2500 meters²
Step-by-step explanation:
Perimeter: 200 = 4w
⇒ 50 = w
Area = w²
= (50)²
= 2500
The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The perimeter of the rectangle = 2( length + Width)
200 = 2( length + Width)
100 - w = L
The area of the rectangle = length × Width
= w(100 - w)
= (-w)²+ 100w
So, (-w)²+ 100w where, a = -1 and b = 100
w = -100/2(-1)
w = 50
The area of the rectangle = (-w)²+ 100w
= (-50)²+ 100(50)
= 2500
Thus, The width of 50 meters will produce the maximum garden area of the rectangle of 2500 square meters.

To take a taxi, it costs \$3.00$3.00 plus an additional \$2.00$2.00 per mile traveled. You spent exactly \$20$20 on a taxi, which includes the \$1$1 tip you left. How many miles did you travel?
Answer:
8 miles
Step-by-step explanation:
Given:
To take a taxi initial cost = $ 3.00
Per mile cost = $ 2.00
Total spent = $20
Tip Given = $ 1
To find:
Total miles traveled=?
Solution:
Now the total cost f the ride was $ 20
As we see that initial cost for all the trips would stay the same
Let someone travels x miles
then according to the given
Initial cost + 2 * miles traveled + tip = total cost
Putting from the given values it becomes
3 + 2 * x + 1 = 20
Now we have to find x here which is the total miles traveled
solving the above equation
3+1+2x=20
4+2x=20
2x=20-4
2x=16
dividing both sides by 2
x =8 miles
so total miles travelled by the person is 8 miles
Answer: 8 miles you traveled.

The height, h(t), in feet of an object thrown into the air with an initial upward velocity of 63 feet per second is given by the formula h(t) = -16t2 + 63t, where t is the time in seconds. What is the height, in feet, of the object after 3 seconds?
Answer:
The height of the object after 3 seconds is 45 feets.
Step-by-step explanation:
The height of an object thrown into the air with an initial upward velocity of 63 feet per second is given as
[tex]h(t)=-16t^2+63t[/tex]
Where, h(t) is height of the object in feet and t is the time in seconds.
We have to find the height of the object after 3 seconds. So, substitute t=3.
[tex]h(3)=-16(3)^2+63(3)[/tex]
[tex]h(3)=-16(9)+189[/tex]
[tex]h(3)=-144+189[/tex]
[tex]h(3)=45[/tex]
Therefore height of the object after 3 seconds is 45 feets.
To calculate the height of an object after 3 seconds using the equation h(t) = -16t^2 + 63t, substitute t with 3 and solve. This results in a height of 45 feet.
To find the height after 3 seconds, we substitute t with 3 into the equation, getting h(3) = -16(3)2 + 63(3). Calculating this step-by-step, we first find the square of 3, which is 9, and then multiply it by -16 to get -144. Next, we multiply 63 by 3 to get 189. Adding these two results together, we end up with 45 feet. Therefore, the height of the object after 3 seconds is 45 feet.

When 4 is subtracted from the square of a number, the result is 3 times the number. Find the negative solution.
Answer:
-1
Step-by-step explanation:
because if you put it in a equation for you get x^2-4=3x therefore you use the quadratic formula and solve the two answers you get are 4 and -1 so since its negative solution it must be -1 must be the square
The negative solution for a quadratic equation, set up to represent the expression 'When 4 is subtracted from the square of a number, the result is 3 times the number', is -1.
Explanation:The subject of this question is a quadratic equation. If we let n be the number, the provided question can be rewritten as:
n² - 4 = 3n
To solve this equation for n, we rearrange terms to get a standard quadratic equation:
n² - 3n - 4 = 0
We can solve this equation using the quadratic formula:
n = [-b ± sqrt(b² - 4ac)] / (2a)
Substituting the values a = 1, b = -3, c = -4 into the formula, we obtain:
n = [3 ± sqrt((-3)² - 4 × 1 × -4)] / (2 × 1)
which simplifies to:
n = [3 ± sqrt(9 + 16)] / 2 = [3 ± sqrt(25)] / 2 = [3 ± 5] / 2
Thus we have two solutions:
n = 8/2 = 4 and n = -2/2 = -1
Since we are looking for the negative solution, the number we are looking for is -1.

What is the greatest common factor of the two terms in the expression x^5y^2+x^2y^7z
The greatest common factor of [tex]x^5y^2[/tex] and [tex]x^2y^7z[/tex]is [tex]x^2y^2[/tex].
Explanation:To find the greatest common factor (GCF) of two or more terms, we need to identify the largest possible number that divides both terms evenly. In this case, we have two terms,[tex]x^5y²[/tex]and [tex]x²y^7z.[/tex]
Firstly, let's simplify the terms by removing any common factors. Here, we can see that both terms have 'x' and 'y' in common. So, let's remove them from both terms to simplify them.
[tex]x^5y²[/tex]becomes [tex]x^3y²[/tex]
[tex]x^2y^7z[/tex]becomes [tex]x^2y^5z[/tex]
Now, let's look for any common factors between these simplified terms. We can see that both terms have 'x' raised to the power of 2 in common. So, let's remove this factor from both terms.
[tex]x^3y²[/tex] becomes xy²
[tex]x^2y^5z[/tex] becomes [tex]xy^3z[/tex]
Now, let's look for any further common factors between these simplified terms. We can see that both terms have 'y' raised to the power of 2 in common. So, let's remove this factor from both terms.
xy² becomes xy
[tex]xy^3z[/tex] becomes xyz
Finally, we can see that both simplified terms now share a common factor of 'xy'. Therefore, 'xy' is the greatest common factor (GCF) of our original two terms, which is x²y² when we replace 'x' and 'y' with their original powers.

Jupiter has 11 more than 4 times as many moons has Neptune. Neptune has 14 moons. Let j equal the number of moons Jupiter has.
Final answer:
Jupiter has 67 moons.
Explanation:
To solve this problem, let's define j as the number of moons Jupiter has. According to the given information, Jupiter has 11 more than 4 times as many moons as Neptune, which has 14 moons. So, we can set up an equation: j = 4n + 11, where n is the number of moons Neptune has. Since Neptune has 14 moons, we can substitute that value into the equation: j = 4(14) + 11. Simplifying further, we get j = 56 + 11 = 67. Therefore, Jupiter has 67 moons.

There are 70 students in the school band. 40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders. How many band members are sixth graders? How many band members are seventh graders? What percentage of the band members are eighth graders?
Answer:
The band members of sixth graders are 28.
The band members of seventh graders are 14.
The percentage of the band members eighth graders are 40% .
Step-by-step explanation
Formula
[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]
As given
There are 70 students in the school band.
40% of them are sixth graders, 20% are seventh graders, and the rest are eighth graders.
Now first find out the band members are sixth graders .
Percentage = 40%
Total value = 70
Put in the formula
[tex]40 = \frac{Number\ of\ band\ members\ are\ sixth\ graders\times 100}{70}[/tex]
[tex]Number\ of\ band\ members\ are\ sixth\ graders = \frac{40\times 70}{100}[/tex]
[tex]Number\ of\ band\ members\ are\ sixth\ graders = \frac{2800}{100}[/tex]
[tex]Number\ of\ band\ members\ are\ sixth\ graders = 28[/tex]
Therefore the number of band members are from sixth graders are 28 .
Now first find out the band members are seventh graders .
Percentage = 20%
Total value = 70
[tex]20 = \frac{Number\ of\ band\ members\ are\ seventh\ graders\times 100}{70}[/tex]
[tex]Number\ of\ band\ members\ are\ seventh\ graders = \frac{20\times 70}{100}[/tex]
[tex]Number\ of\ band\ members\ are\ seventh\ graders = \frac{1400}{100}[/tex]
[tex]Number\ of\ band\ members\ are\ seventh\ graders = 14[/tex]
Therefore the number of band members are from seventh graders are 14.
Now find out the percentage of the eighth graders of the band members.
Total number of band members = sixth graders members + seventh grade members + eighth graders members
As sixth graders members = 28
seventh grade members = 14
Total number of band members = 70
Put in the above
70 = 28 + 14 + eighth graders members
70 - 42 = eighth graders members
28 = eighth graders members
Put in the percentage formula
[tex]Percentage = \frac{28\times 100}{70}[/tex]
[tex]Percentage = \frac{2800}{70}[/tex]
Percentage = 40%
Therefore the percentage of the band members are eighth graders is 40 %.

Please help! Write the slope-intercept form of the equation for the line.
a. y=-8/7x-3/2
b. y=-3/2x+7/8
c. y=-7/8x-3/2
d. y=7/8x-3/2
Answer:
C
Step-by-step explanation:
The slope intercept of a line is y=mx +b where
m is the slope which is calculated as the vertical distance divided by the horizontal distance between two points.b is the y-intercept for value on the y-axis for which the line crosses it.This graph crosses the y-axis (the vertical line) halfway between -1 and -2. This is -3/2. This means only answers a, c, and d are options.
The graph moves up from -3/2 to its next point at (-4,0). We calculate the slope using:
Slope:[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We substitute [tex]x_1=0\\y_1=-1.5[/tex] and [tex]x_2=-4\\y_2=2[/tex]
[tex]m=\frac{2-(-1.5)}{-4-0}[/tex]
[tex]m=\frac{2+1.5}{-4}=\frac{3.5}{-4} =-0.875[/tex]
This decimal is equivalent to -7/8. This means C is the answer.
This equation represents a line with a slope of [tex]\( -\frac{7}{8} \)[/tex](meaning the line slopes downward from left to right) and a y-intercept of [tex]\( -\frac{3}{2} \)[/tex](where the line crosses the y-axis). The correct answer is option c
The slope-intercept form of the equation of a line is [tex]\( y = mx + b \),[/tex] where m represents the slope of the line, and b represents the y-intercept (where the line crosses the y-axis).
Let's analyze each option:
a.[tex]\( y = -\frac{8}{7}x - \frac{3}{2} \):[/tex]
- Slope [tex]\( m = -\frac{8}{7} \)[/tex]
- y-intercept [tex]\( b = -\frac{3}{2} \)[/tex]
b. [tex]\( y = -\frac{3}{2}x + \frac{7}{8} \):[/tex]
- Slope [tex]\( m = -\frac{3}{2} \)[/tex]
- y-intercept[tex]\( b = \frac{7}{8} \)[/tex]
c.[tex]\( y = -\frac{7}{8}x - \frac{3}{2} \):[/tex]
- Slope [tex]\( m = -\frac{7}{8} \)[/tex]
- y-intercept [tex]\( b = -\frac{3}{2} \)[/tex]
d.[tex]\( y = \frac{7}{8}x - \frac{3}{2} \):[/tex]
- Slope[tex]\( m = \frac{7}{8} \)[/tex]
- y-intercept[tex]\( b = -\frac{3}{2} \)[/tex]
Among the given options, the correct slope-intercept form is option c:
[tex]\[ \boxed{y = -\frac{7}{8}x - \frac{3}{2}} \][/tex]

Answer:
B would be the answer for this question.
Step-by-step explanation:
Answer: The fourth term is [tex]5000x^2.[/tex]
Step-by-step explanation: We are given to find the fourth term in the expansion of the following binomial :
[tex]B=(2x+5)^5.[/tex]
We know that
the r-th term in the expansion of the binomial [tex](a+x)^n[/tex] is given by
[tex]T_r=^nC_ra^{n-(r-1)}b^{r-1}.[/tex]
For the given term, we have
n = 5 and r = 4.
Therefore, fourth term is given by
[tex]T_4\\\\=^5C_{4-1}(2x)^{5-(4-1)}5^{4-1}\\\\=^5C_3(2x)^25^3\\\\=\dfrac{5!}{3!(5-3)!}\times4x^2\times125\\\\\\=\dfrac{5\times4}{2\times1}\times 500x^2\\\\=5000x^2.[/tex]
Thus, the fourth term is [tex]5000x^2.[/tex]
If a right triangle has sides of length a, b and c and if c is the largest, then it is called the "hypotenuse" and its length is the square root of the sum of the squares of the lengths of the shorter sides (a and b). assume that variables a and b have been declared as doubles and that a and bcontain the lengths of the shorter sides of a right triangle: write an expression for the length of the hypotenuse.
Assuming this is for a programming language like c++, then the expression might look like
c = sqrt(a*a + b*b)
or you can use the pow function (short for power function)
c = sqrt( pow(a,2) + pow(b,2) )
writing "pow(a,2)" means "a^2"; similarly for b as well.
the length of hypotenuse can be found using the formula [tex]c = \sqrt{a^2+b^2}[/tex]
The pytharogas theorem states that:
[tex]hypotenuse^2 = perpendicular^2+ base^2[/tex]
The Pythagorean Theorem relates the length of the legs of a right triangle, labeled a and b, with the hypotenuse, labeled c. The relationship is given by:
[tex]a^2 + b^2 = c^2[/tex]
This can be rewritten, solving for c:
[tex]c = \sqrt{a^2+b^2}\\\\[/tex]
Thus, the length of hypotenuse can be found using the formula [tex]c = \sqrt{a^2+b^2}[/tex]
