I need to write a word problem for this equation and I don't know how to get started. Help!!!! N + (n + 8) + 2n = 364
Answer:
n = 89
Step-by-step explanation:
Ok so,
n + (n+8) + 2n =364
n+n+8+2n = 364
4n + 8 = 364
4n = 356
n = 89
I checked it...its right
if you have any questions please ask me
hope this helps. have a good day :)!!

The total cost of flooring a room at Rs .9.50 per square meter is Rs 760, If the length of the room is 10 m, find its breadth.
Answer:
8 metre
Step-by-step explanation:
cost of flooring per square metre = Rs .9.50
total cost of flooring= Rs760
Area of room= 760/9.50
= 80 m^2
Area of the given room= Lenght × Breadth
length of the room is = 10 m
80= 10 × Breadth
Breadth= 80/10= 8 m
Hence, breadth of the room is 8metre

a circle with a circumference of 40.82 centimeters what is the area of the circle is 3.14 for pi
You need two formulas for this:
C = πd or C = 2πr ( d = 2r ) Where C is circumference and d is diameter, r is radius
A = πr² Where A is area, and r is radius
First you get the diameter and radius by substituting the value of pi and circumference. With that, you can calculate the Area of the circle with the second formula. square² the radius then multiply it to 3.14. Remember that radius is half of diameter.
Answer:
[tex]\boxed {\boxed {\sf a=132.665 \ cm^2}}[/tex]
Step-by-step explanation:
1. Find the Radius
We are given the circumference of 40.82 centimeters. The formula for circumference is
[tex]c=\pi d[/tex]
The diameter is twice the radius, so we can also write this formula as:
[tex]c= \pi 2r[/tex]
Substitute 40.82 for the circumference and use 3.14 for pi.
[tex]40.82 \ cm= (3.14) 2r[/tex]
[tex]40.82=6.28 r[/tex]
6.82 and r are being multiplied. The inverse of multiplication is division. Divide both sides by 6.82
[tex]\frac{40.82 \ cm}{6.28}=\frac{6.28 r}{6.82}[/tex]
[tex]6.5 \ cm=r[/tex]
2. Calculate the Area
Now we can calculate the area using this formula:
[tex]a= \pi r^2[/tex]
The radius is 6.5 centimeters and we are using 3.14 for pi.
[tex]a= 3.14(6.5 \ cm)^2[/tex]
Solve the exponent.
(6.5 cm)²= 6.5 cm * 6.5 cm=42.45 cm²[tex]a= 3.14 (42.45 \ cm^2)[/tex]
Multiply.
[tex]a=132.665 \ cm^2[/tex]
The area is 132.665 square centimeters.

why do the angles in a triangle add up to 180 degrees?
Answer:
Angles in a triangle add up to 180 degrees because triangles are have the measure and sizes of quadrilaterals, which have an angle measure of 360 degrees. If you divide 360 degrees by 2, you will get 180 degrees.
Step-by-step explanation:
Hope that helps!
Answer:
Let N equal the number of angles in the polygon
Use the formula:
(N x 180)-360 = the sum of all the angles in the polygon
A triangle has 3 angles so:
(3 x 180)-360=180 degrees
(this formula works for any polygon, regardless of the number of it's angles)

x^2y+y^2-30x+221=0 find the radius
Answer:
2
Step-by-step explanation
Let's complete the square. We get:
(x^2-30x)+y^2+221=0
(x^2-30x+225)+y^2+221-225=0
(x-15)^2+y^2-4=0
(x-15)^2+y^2=4
By analyzing this, we see that the radius is just :[tex]\sqrt{4}[/tex]=2

Mrs. Montgomery earns a 6.5% commission on her total sales. Last month, she had sales of $55,780.
How much commission did Mrs. Montgomery earn last month?What was her total pay for the month?
Answer:
Commission: $3625.70
Total (sales + commission): $59405.70
Step-by-step explanation:
6.5% of 55780 = 0.065 × 55780 = 3625.7
55780 increase 6.5% =
55780 × (1 + 6.5%) = 55780 × (1 + 0.065) = 59405.7
