A seven sided polygon with angle measures x, x minus 15, 107, x plus 7, 125, 122, and 131 degrees.
What is the value of x?
Answers
Answer:
x = 150
Step-by-step explanation:
x + x - 15 + 107 + x + 7 + 125 + 122 + 131 = 630
3x + 180 = 630
3x = 450
x = 150
The value of x is 150
What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
We are given that seven sided polygon with angle measures x, x minus 15, 107, x plus 7, 125, 122, and 131 degree
Therefore, the sum of all the angles are;
x + x - 15 + 107 + x + 7 + 125 + 122 + 131 = 630
3x + 180 = 630
3x = 450

Answer:
A) [tex]-\frac{7}{4}[/tex]
Step-by-step explanation:
For this question, we can use the rise over run method, which means y over x.
So count how many it takes for the point on top to get to the bottom by x and y.
It takes 7 spaces down (y) and 4 spaces to the right (x)
So do rise over run and we get
[tex]\frac{7}{4}[/tex]
Meaning that B and C are incorrect. Now what about A and D?
Well the slope is moving down, meaning that it is a negative slope, therefore there must be a negative sign for the slope.
[tex]-\frac{7}{4}[/tex]
A. is correct.

Answer:
x = 4 sqrt(5)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
8^2 + x^2 = 12^2
64+ x^2 =144
Subtract 64 from each side
x^2 = 144-64
x^2 =80
Take the square root of each side
sqrt(x^2) = sqrt(80)
x = sqrt(16*5)
x = 4 sqrt(5)

WeMoveU charges an hourly rate for a moving team to load and unload a truck. The charges is a different hourly rate for a team pack and unpack boxes. Use the quotes below to determine the company's hourly rates. Weekday Move: 5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost. Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
Let us represent:
Hours of Loading and Unloading = X
Hours of packing = y
5hours of loading and unloading services. 4 hours of packing and unpacking service. $730 total cost.
5x + 4y = 730..... Equation 1
Weekend Move: 4 hours of loading and unloading services. 5 hours of packing and unpacking services. $710 total cost.
4x + 5y = 710.... Equation 2
Combining both Equations together
5x + 4y = 730..... Equation 1
4x + 5y = 710.... Equation 2
We solve using Elimination method

Find the compound interest on 5000 at 12% interest for 15 years.
if the interest is compounded semi-annually.
Answers
18000
Step-by-step explanation:
5000*12%= 600 600× 30= 18000 15 years semi annually = 30 x
The compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58
To find the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually, we can use the formula:
A = P(1 + r/n)^(n*t)
where:
P = principal amount = $5,000
r = annual interest rate = 12% = 0.12
n = number of times compounded in a year = 2 (compounded semi-annually)
t = time period in years = 15
A = amount after t years
Plugging in the values, we get:
A = 5000(1 + 0.12/2)^(2*15)= $27,243.58
So, the amount after 15 years is $27,243.58. To find the compound interest, we can subtract the principal amount from the amount after 15 years:
Compound interest = A - P
= $27,243.58 - $5,000
= $22,243.58
Therefore, the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58.
