Answer:
52 sides
Step-by-step explanation:
The only way I know how to do this is to create one fraction which is a combination of 2 steps used when 1 of the interior angles is known.
Formula
360/(180 - 9000/s ) = s
Multiply denominator and numerator on the left by s.
360 * s
======= = s
s* (180 - 9000/s)
Remove the brackets on the denominator
360s
================ =s
180s - 9000
Cancel the numerators s's.
360 / (180s - 9000) = 1
Multiply both sides by 180s - 9000
360 =180s - 9000
Add 9000 to both sides
360 + 9000 = 180s
9360 = 180s
Divide by 180
9360/180 = 180/180 s
s = 52

Answer:
∠A = 45°
Step-by-step explanation:
The sum of angles in a triangle = 180°.
That means in the triangle ABC, ∠A + ∠B + ∠C = 180°.
Given ∠B = 90° and ∠C = 45°.
⇒ ∠A + 90° + 45° = 180°
⇒ ∠A = 180 - 90 - 45
⇒ ∠A = 45° is the required answer.
The area of a circle is 28.26 square kilometers. What is the circles diameter
Answer:
6km
Step-by-step explanation:
Area of circle = πr²
Where r = radius, π= 3.14, A = 28.26km²
A = 3.14 x r²
3.14 r2 = 28.26
Divide both sides by 3.14
r²= 28.26/3.14
r² = 9
Square root both sides
r= √9
r= 3
Radius = 3km
Note : Diameter = 2 x radius
Diameter = 3 x 2
Diameter = 6km

the temper ire of chicken soup is 192.7 F as it cools the temperature of the soup decreases 2.3 what is the temperature of the soup after 25 minutes
Final answer:
To find the new temperature of the soup after cooling for 25 minutes, multiply the rate of decrease, 2.3 F/min, by 25 minutes to find the total decrease in temperature, which is 57.5 F. Then subtract this from the initial temperature of 192.7 F to get the final temperature of 135.2 F.
Explanation:
The question is about calculating the new temperature of chicken soup after it cools for a certain period. The initial temperature of the soup is 192.7 F, and it's stated that the soup temperature decreases by 2.3 degrees per minute. Since it's asking for the temperature after 25 minutes, we need to multiply the rate of cooling by the number of minutes.
To calculate the new temperature:
Decrease in temperature = 2.3 F/min × 25 min = 57.5 F
The new temperature would then be:
Initial temperature - Decrease in temperature = 192.7 F - 57.5 F = 135.2 F.
Problem Solving Strategies for the Effects of Heat Transfer

McKenzie sells textbooks. She receives 7% on her first $1,000 in sales and 15% on the balance of her sales. How much would she earn in commission if her sales in one month were $14,500? Enter your answer as a dollar amount rounded to the nearest cent. Do not type a dollar sign symbol in the box.
The commission would be $2095.
Step-by-step explanation:
Given,
Commission on first $1000 = 7%
Amount of commission = 0.07*1000 = $70
Worth of sold items = $14,500
We will subtract $1000 from it.
Balance = 14500-1000 = $13500
Commission on balance = 15% = 0.15
Amount of commission = 0.15*13500
Amount of commission = $2025
Total commission = 70+2025 = $2095
The commission would be $2095.

McKenzie would earn $2,095 in commission if her sales for the month were $14,500.
Explanation:To calculate McKenzie's commission, we need to determine the amount of sales that fall under the 7% rate and the amount that falls under the 15% rate. First, we calculate the commission on the first $1,000 in sales: 7% of $1,000 = $70. Next, we calculate the commission on the remaining sales: $14,500 - $1,000 = $13,500. 15% of $13,500 = $2,025.
Finally, we add the two commissions together to get the total commission: $70 + $2,025 = $2,095. So McKenzie would earn $2,095 in commission if her sales for the month were $14,500.

What would be the area?
Total area is 102.3 yd²
Step-by-step explanation:
Step 1:Total area = area of the parallelogram + area of the right triangle
Step 2:Calculate the area of the parallelogram.
Base = 11 yd, Height = 6.2 yd
⇒ Area of the parallelogram = Base × Height = 11 × 6.2 = 68.2 yd²
Step 3:Calculate the area of the right triangle.
Height = 6.2 yd, Base = 11 yd (Since opposite sides of a parallelogram are equal)
⇒ Area of the triangle = 1/2 × base × height = 1/2 × 11 × 6.2 = 34.1 yd²
Step 4:Calculate the total area.
⇒ Total area = 68.2 + 34.1 = 102.3 yd²
The sum of two numbers is 92. The difference of two numbers is 24. What are the numbers?
Answer:
a = 58
b = 34
Step-by-step explanation:
a + b = 92
a - b = 24
add
a + b + a - b = 92 + 24
2a = 116
a = 116 : 2
a = 58
b = 92 - 58
b = 34
Answer:
Step-by-step explanation:
Let the numbers be x and y
x + y = 92..........(1)
x - y = 24..........(2)
Adding (1) and (2)
2x = 116
x = 116/2
x = 58
From (1)... x + y = 92
58 + y = 92
y = 92 - 58
y = 34
Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborhood. What is the total number of fliers they gave out
The volunteers gave 1368 fliers in total.
Step-by-step explanation:
Given,
Fliers given by volunteers in first neighborhood = [tex]\frac{21}{38}[/tex]
Remaining fliers = 612
Fraction of remaining fliers = [tex]1-\frac{21}{38}=\frac{38-21}{38}[/tex]
Fraction of remaining fliers = [tex]\frac{17}{38}[/tex]
Let,
x be the total fliers given by volunteers.
[tex]\frac{17}{38}\ of\ x=612[/tex]
[tex]\frac{17}{38}x=612[/tex]
Multiplying both sides by [tex]\frac{38}{17}[/tex]
[tex]\frac{38}{17}*\frac{17}{38}x=612*\frac{38}{17}\\\\x=\frac{23256}{17}\\\\x=1368[/tex]
The volunteers gave 1368 fliers in total.

Wayne's savings to Stef's savings were in the ratio 5:6
After spending $28 each the ratio became 1:4
I need to find wayne's savings BEFORE he spent 28 and Stef's savings AFTER she spent 28
HELP PLEASE TY
Answer:
a) $30
b) $8
Step-by-step explanation:
Wayne's savings to Stef's savings were in the ratio 5:6.
Let, Wayne's saving is 5x and Stef's saving is 6x.
Now, given that after spending $28 each the ratio became 1:4.
So, we can write the equation as
[tex]\frac{5x - 28}{6x - 28} = \frac{1}{4}[/tex]
⇒ 20x - 112 = 6x - 28
⇒ 14x = 84
⇒ x = 6
a) Therefore, Wayne's savings before he spends $28 is $(5 × 6) = $30
b) And, Stef's savings after she spends $28 will be $(6x - 28) = $(6 × 6 - 28) = $8 (Answer)
wich function represents exponential growth with a growth with a 5% rate of change?

c- f(x)= 4(0.95)n

Answer:the answer is B
Step-by-step explanation:
The function that represents the exponential growth is
f(x) = 4 x [tex]1.05^n[/tex].
Option B is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
An exponential growth function.
Rate of change = 5%
This means,
There is a growth per year of 5%.
The function can be represented as,
f(x) = a [tex](1 +0.05)^n[/tex]
f(x) = a x [tex]1.05^n[/tex]
Where 100% = 1 and 5% = 0.05
Let a = 4
f(x) = 4 x [tex]1.05^n[/tex]
Thus,
The exponential growth function is
f(x) = 4 x [tex]1.05^n[/tex]
