Answer:
[tex]A = 118ft^2[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, we have:
[tex]\theta = 80[/tex]
[tex]r = 13ft[/tex] -- Radius
Required
Determine the area of the sector
Area (A) of a sector is calculated as:
[tex]A = \frac{\theta}{360} * \pi r^2[/tex]
Substitute values for r and [tex]\theta[/tex]
[tex]A = \frac{80}{360} * \pi 13^2[/tex]
[tex]A = \frac{80}{360} * \pi *169[/tex]
[tex]A = \frac{80*169}{360} * \pi[/tex]
[tex]A = \frac{13520}{360} * \pi[/tex]
Take [tex]\pi[/tex] as [tex]\frac{22}{7}[/tex]
[tex]A = \frac{13520}{360} * \frac{22}{7}[/tex]
[tex]A = \frac{13520 * 22}{360 * 7}[/tex]
[tex]A = \frac{297440}{2520}[/tex]
[tex]A = 118ft^2[/tex]-- approximated

A statue that is 80 m tall stands on a 625 m2 base. An artist creates a replica using a ratio of 1:15. What is the area of the replica's base?
Answer: [tex]2.78m^{2}[/tex]
Step-by-step explanation:
given data:
height of the statue = 80m.
base of the statue = [tex]625m^{2}[/tex].
scale of the statue replica = 1:15.
solution:
[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]
[tex]= \frac{625m^{2} }{225}[/tex]
= [tex]2.78m^{2}[/tex]
the area of the replica is [tex]2.78m^{2}[/tex]
Answer:
2.78 m^2 is the correct answer. :)

A rectangle has length 4 inches and width 2 inches. If the length and width of the rectangle are each reduced by 50 percent, by what percent will the area of the rectangle be reduced?
Answer: 25%
Step-by-step explanation:
Given: A rectangle has length 4 inches and width 2 inches.
Area = Length x width
= 4 inches x 2 inches
= 8 square inches
If length is reduced by 50% , then length [tex]=0.5\times4=2\text{ inches}[/tex]
If width is reduced by 50% , then length [tex]=0.5\times2=1\text{ inch}[/tex]
Reduced area = (reduced length) x (reduced width)
= 2 inches x 1 inch
= 2 square inches
The percentage of the area of the rectangle be reduced :-
[tex]\dfrac{\text{Reduced area}}{\text{Original area}}\times100 \\\\=\dfrac{2}{8}\times100\% \\\\=25\%[/tex]
Hence, the percent of the area of the rectangle be reduced = 25%

Answer:
Slope is often denoted by the letter m; there is no clear answer to the question why the letter m is used for slope, but its earliest use in English appears in O'Brien (1844) who wrote the equation of a straight line as "y = mx + b" and it can also be found in Todhunter (1888) who wrote it as "y = mx + c".

The 8th Grade wants to raise money for a field trip that costs $800. 15 students are in charge of fundraising. What is the minimum amount of money they each have to raise to achieve their goals (if they each raise the same amount of money)?
Answer: $54.35
Step-by-step explanation:
If each one of the 15 students raises the same amount, let's define this amount by the variable X, then the total amount they will collect is 15 times X, or:
15*X
And the minimum amount they need to collect is $800
Then we will have the inequality:
15*X ≥ $800
Now we can divide both sides by 15 to get the minimum amount that each student needs to raise:
(15*X)/15 ≥ $800/15
X ≥ $54.33...
Where we should round up the right number to $54.35, because we can not have a $0.0333... and if we round down, they would collect less than $800.
Then the inequality is:
X ≥ $54.35
This means that the minimum amount that each one of the 15 students needs to collect is $54.35
If the temperature outside increases by 3 1/2 degrees every 1 1/2 hours, by how much will the temperature increase after 4 hours?
please answer in fractions.
Part 1:
What is the rate per hour of the temperature increase?
Part 2:
How much will the temperature increase after 4 hours?
Answer:
2 1/3 ; 9 1/3
Step-by-step explanation:
Given that:
Outside temperature increases by 3 1/2 degrees every 1 1/2 hours
The rate per hour of temperature increase will be :
Let rate per hour = x
3 1/2 = 1 1/2
x = 1
Cross multiply :
1 1/2 * x = 3 1/2 * 1
3x/2= 7/2
Multiply both sides by 2/3
3x/2 * 2/3 = 7/2 * 2/3
x = 14/ 6
x = 2 2/6
x = 2 1/3
Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.
2.) Temperature increase after 4 hours :
(Temperature rate per hour * number of hours)
(2 1/3) * 4
(7/3) * 4
28 / 3
= 9 1/3
Hence, temperature increase after 4 hours = 9 1/3
2 1/3 ; 9 1/3
Step-by-step explanation:
Given that:
Outside temperature increases by 3 1/2 degrees every 1 1/2 hours
The rate per hour of temperature increase will be :
Let rate per hour = x
3 1/2 = 1 1/2
x = 1
Cross multiply :
1 1/2 * x = 3 1/2 * 1
3x/2= 7/2
Multiply both sides by 2/3
3x/2 * 2/3 = 7/2 * 2/3
x = 14/ 6
x = 2 2/6
x = 2 1/3
Hence, outside temperature increases at the rate of 2 1/3 degrees per hour.
2.) Temperature increase after 4 hours :
(Temperature rate per hour * number of hours)
(2 1/3) * 4
(7/3) * 4
28 / 3
= 9 1/3
Hence, temperature increase after 4 hours = 9 1/3

6 StartRoot 2 EndRoot(cos(225°) + isin(225°))

Answer:
A
Step-by-step explanation:
edge
The polar form of z is 6√2(cos(135°) + isin(135°)).
What Is Polar Form of Complex Numbers?Complex numbers are represented in polar form as the complex number's modulus r and argument combined. Given as z = r cosθ + i r sinθ = r (cosθ + i sinθ). the polar form of the complex number z = x + iy with coordinates (x, y) is given. Polar coordinates of real and imaginary numbers in the coordinate system are used to express the polar form. A complex number in a two-dimensional coordinate system is A = x + i y
Given the point z
From the positive real axis, the angle to the point in the second quadrant is calculated (the x-axis). The only options that make sense for the second quadrant are the 135° angles, which fall between 90° and 180°.
The square root of the sum of the squares of z's components determines its magnitude:
|z| = [tex]\sqrt{x^{2} + y^{2} }[/tex]
here x = -6 and y = 6
|z| = √(-6²) + (6²)
z = 6√2
polar form is
z = 6√2(cos(135°) + isin(135°))
Hence the complex form is 6√2(cos(135°) + isin(135°)).
