Answer:
A = 660.72 in^2 - A = 98 in^2 = 562.7 in^2
Step-by-step explanation:
Formula for a seven sided polygon/heptagon is:
A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n
n n = 7 sides
side length a = 13.4841 in
inradius r = 14 in
circumradius R = 15.5388 in
area A = 660.72 in^2
perimeter P = 94.3886 in
interior angle x = 128.571 °
exterior angle y = 51.4286 °
To calculate the square from a diameter use this formula: q = √(2a^2) = a√2
side length a = 9.8994949366117 in
diagonal q = 14 in
perimeter P = 39.597979746447 in
area A = 98 in^2
As a town gets smaller, the population of its high school decreases by 8% each year. The senior class has 320 students now. In how many years will it have about 100
students? Write an equation. Then solve the equation without graphing.
Answer:
in 13.95 years the senior class will have 100 students.
Step-by-step explanation:
P(h) = p(0.92)^t (equation for exponential change)
P(h) - population of highschool (or senior class) = 100
p - staring amount = 320
t = time in years
100 = 320(0.92)^t
1/3.2 = .92^t (divide both sides by 320)
log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)
13.9497 = t

Can someone please help me with this math question??
A movable section of stage has the shape of an isosceles right triangle. You need to apply 2 coats of paint to all but the bottom. The paint covers approximately 90 square feet per quart. How many quarts of paint do you need to buy? You need to buy quarts of paint.
Answer:
You need to buy 3 quarts of paint.
Step-by-step explanation:
Given
[tex]Coats =2[/tex]
[tex]Paint = 90ft^2/qt[/tex]
See attachment for stage
Required
Determine the number of quarts needed
First, we calculate the surface area of the stage (without the base).
This is calculated as:
Area = Area of Rectangle1 + Area of Rectangle 2 + 2 * Area of each triangle on both sides.
For the first rectangle, we have:
[tex]A_1 =Length * Width[/tex]
[tex]A_1 = 15.2 * 19.5 =296.4[/tex]
For the second rectangle, we have:
[tex]A_2 =Length * Width[/tex]
[tex]A_2 = 6* 19.5 = 117[/tex]
For each triangle on both sides
[tex]A_3 = 0.5 * Base * Height[/tex]
[tex]A_3 = 0.5 * 14 * 6 = 42[/tex]
So, the total area is:
[tex]Area = A_1 + A_2 + 2 *A_3[/tex]
[tex]Area = 296.4 + 117+ 2 *42[/tex]
[tex]Area = 497.4ft^2[/tex]
The amount of paint need is:
[tex]Amount = \frac{Area}{2\ coats}[/tex]
From the question, we understand that:
[tex]1\ coat =90ft^2/quart[/tex]
Multiply both sides by 2
[tex]2 * 1\ coat =90ft^2/quart * 2[/tex]
[tex]2 \ coats =180ft^2/quart[/tex]
So, we have:
[tex]Amount = \frac{Area}{2\ coats}[/tex]
[tex]Amount = \frac{497.4ft^2}{180ft^2/quart}[/tex]
[tex]Amount = \frac{497.4ft^2}{180ft^2}quart[/tex]
[tex]Amount = \frac{497.4}{180}quart[/tex]
[tex]Amount = 2.763\ quarts[/tex]
[tex]Amount \approx 3\ quarts[/tex] --- approximated

What is (f+g)(x)? f(x)= – x2+7x g(x)=3x Write your answer as a polynomial or a rational function in simplest form.
Answer:
[tex](f+g)(x) = -x^2 + 10x[/tex]
Step-by-step explanation:
We are given these two following functions:
[tex]f(x) = -x^2 + 7x[/tex]
[tex]g(x) = 3x[/tex]
Sum of the functions:
To find the sum of the functions, we combine the like terms. So
[tex](f+g)(x) = f(x) + g(x) = -x^2 + 7x + 3x = -x^2 + (7+3)x = -x^2 + 10x[/tex]
[tex]-x^2 + 10x[/tex] is the answer

*WILL GIVE BRAIONLIEST FOR BEST ANSWER NO VIRUS LINKS OR I WILL REPORT* Given the data set, calculate the range and the mode:
{9, 3, 1, 8, 3, 6}
Question 8 options:
A, Range: 8, Mode: 3
B. Range: 3, Mode: 8
C, Range: 6, Mode: 3
D. Range: 8, Mode: 1
Answer:
the answer is A
Step-by-step explanation:
first, you would have to figure out the range, which would be 8 because to find the range, you have to get the larger number and the smaller number and subtract. So that answer would be 9-1=8 so range-1
To find the mode you will have to look at the list of numbers and see which one occurs that most and that would be the mode. Therefore, the range is 8, and the mode is 3.
Answer- range1, mode:3

12 O 44 Madeline, Tyra, and Imogen are helping consolidate leftover pizza slices after a party. Each one of them has a box with leftovers. Madeline says the leftover slices in her box form a 203° angle . Tyra says the leftover slices in her box form a 59 After hearing those descriptions from Madeline and Tyra, Imogen wonders if the leftover slices would all fit into one box (meaning one full circle of 360° or less). It is possible if the angle measure of her leftover slices is no larger than [Drop Down 1]. If each slice has an angle of 40 the maximum amount of slices Imogen can fit is [Drop Down 2]. 1 mron Down 11
Answer:
i. The angle measure of Imogen's leftover should not be larger than [tex]98^{o}[/tex]
ii. The maximum number of slices that Imogen can fit is 2.
Step-by-step explanation:
The leftover in Madeline's box forms angle = 203°
The leftover in Tyra's box forms angel = [tex]59^{o}[/tex]
Sum of angles formed = 203° + [tex]59^{o}[/tex]
= [tex]262^{o}[/tex]
Given that one box = 1 full circle of 360°. Then,
the angle formed by the leftover in Imogen's box = 360° - [tex]262^{o}[/tex]
= [tex]98^{o}[/tex]
Thus, the angle measure of Imogen's leftover slices should not be larger than [tex]98^{o}[/tex].
If each slice has an angle of [tex]40^{o}[/tex], the maximum number of slice that Imogen can fit = [tex]\frac{98}{40}[/tex]
= 2 [tex]\frac{9}{20}[/tex]
= 2.45
The maximum number of slices that Imogen can fit is 2.
