Given parameters:
Number of sides of the regular body = 10
A decagon has 10 sides.
Unknown:
Sum of the measures of the interior angles = ?
Solution;
To find the sum of the interior angles of a decagon; use the expression below:
Sum of interior angles = (n - 2) x 180
where;
n = number of sides;
So,
Sum of interior angles = (10 - 2) x 180 = 1440°
The sum of interior angle of a decagon is 1440°
can you help me on this problem

3) Car A and B travel in opposite directions. Both cars leave the same location at the same time. Car A is traveling west at a speed of 10 mph more than Car B, which is headed east. Find the speed of Car A if the two cars are 300 miles apart after traveling 3 hours. Chart is optional. Include units in your answer. *
Let, speed of car B is -x.
So, speed of car A is x + 10.
Relative speed of A w.r.t B is ,
[tex]v_{ab}=(x+10)-(-x)\\\\v_{ab}=2x+10\ mph[/tex]
So, time taken by A to travel 300 miles relative to B given by 3 hours .
[tex]v_{ab}=2x+10\\\\\dfrac{300}{3}=2x+10\\\\x = 45 \ mph[/tex]
Therefore, speed of car A is 45 + 10 = 55 mph.
Hence, this is the required solution.

what is the answer for x+7=2(x-15)
Answer:
x=37 Hope this helped <3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x+7=2(x−15)
x+7=(2)(x)+(2)(−15)(Distribute)
x+7=2x+−30
x+7=2x−30
Step 2: Subtract 2x from both sides.
x+7−2x=2x−30−2x
−x+7=−30
Step 3: Subtract 7 from both sides.
−x+7−7=−30−7
−x=−37
Step 4: Divide both sides by -1
Answer:
[tex]\boxed {x = 37}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x + 7 = 2(x - 15)[/tex]
-Use Distributive Property:
[tex]x + 7 = 2(x - 15)[/tex]
[tex]x + 7 = 2x - 30[/tex]
-Take [tex]2x[/tex] and subtract it from [tex]x[/tex]:
[tex]x + 7 - 2x = 2x - 2x - 30[/tex]
[tex]-x + 7 = -30[/tex]
-Subtract [tex]7[/tex] to both sides:
[tex]-x + 7 - 7 = -30 - 7[/tex]
[tex]-x = -37[/tex]
-Divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} = \frac{-37}{-1}[/tex]
[tex]\boxed {x = 37}[/tex]
So, the value of [tex]x[/tex] is [tex]37[/tex].

Below, you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the year. (Let t = 12 represent 2012.) 2012 Value Rate $48,000 $2200 decrease per year
Answer:
[tex]y = 48000 - 2200x[/tex] --- equation
[tex]y = 37000[/tex] --- value at 5th year
Step-by-step explanation:
Given
[tex]Value = \$48000[/tex]
[tex]Rate = \$2200[/tex] decrease
Required
Determine the linear equation
Determine the value at the 5th year
Represent years with x.
If the rate in 1 year is 2200,
in x years, it'll be 2200x (decrement)
So, the value (y) at x years is.
[tex]y = 48000 - 2200x[/tex]
The value at the 5th year is when x = 5.
So, we have:
[tex]y = 48000 - 2200 * 5[/tex]
[tex]y = 48000 - 11000[/tex]
[tex]y = 37000[/tex]
You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?
Answer:
$3
Step-by-step explanation:
Because you subtract $23-$11 to get the total you spent on avocados then you divide 12/4 because you bought 4 avocados
Answer:
3 dollars for each avocado.
Step-by-step explanation:
Since you had 23 dollars in the beginning and 11 dollars in the end, subtract to find out how much was used for the avacados.
23-11=12
Next, since you bought 4 avocados, you divide 12 by 4 to find out how much each cost.
12/4=3
Each avocado cost 3 dollars.
You can check by multiplying 3 by 4.
3x4=12
Then, add the 12 dollars spent to the 11 dollars left.
12+11=23 dollars
The straight line depreciation equation for
a motorcycle is y = -2.150x + 17,200.
(Express your answers as whole
numbers.)
a. What is the original price of the
motorcycle? $17,200.00
b. How much value does the motorcycle
lose per year?
c. How many years will it take for the
motorcycle to totally depreciate?
Given :
The straight line depreciation equation for a motorcycle is y = -2,150x + 17,200.
To Find :
a. What is the original price of the motorcycle? $17,200.00 ?
b. How much value does the motorcycle lose per year?
c. How many years will it take for the motorcycle to totally depreciate?
Solution :
y = -2,150x + 17,200.
Here, y is price and x is unit of time in years.
a)
We know, original price is given when x =0.
So, y = 0 + 17,200
y = $17,200.00
b)
Value motorcycle lose per year is coefficient of x i.e $-2,150.00
c)
Form total depreciate :
y = 0
0 = -2,150x + 17,200
x = 17,200÷2,150
x = 8 years.
Hence, this is the required solution.
Hailey cuts a 7-inch square piece of plywood for a birdhouse. She rotates the piece 90° counterclockwise. What is the length in inches of each side of the piece of plywood after the rotation?
Can someone please help me ASAP!!
Answer:
[tex]\huge\boxed{7\ \text{inches}}[/tex]
Step-by-step explanation:
As I mentioned earlier with a single side (line), rotations do not change the size of something. Only dilations do that. This goes for both lines AND shapes.
However, if the question said she dilated the piece, then yes, the length in inches would be different. However, rotation just changes the position and nothing happens to the length.
Hope this helped!
Simplify the following expression:
2x − 2y + 5z − 2x − y + 3z NEED HELP PLZ :(
A x − 3y + 8z
B 2x − 2y + 8z
C 3y + 8z
D−3y + 8z
Answer:
D) -3y + 8z
Step-by-step explanation:
2x - 2y + 5z - 2x - y + 3z
first, group the same variables together.
2x - 2x - 2y - y + 5z + 3z
then, this step which I don't have a name for.
2x - 2x = 0x.
-2y - y = -3y
5z + 3z = 8z
0x - 3y + 8z
or, -3y + 8z

Step-by-step explanation:
Write the equation of the line that passes through the point (4, 3) and has a slope of

y = 5/4x + 17
y = 5/4x - 2
y = 5/4x - 8
y = 5/4x + 1/4
A television set can be purchased with a $200 down payment plus a $39.99 monthly payment. Alternatively, the television can be purchased with no money down and monthly payments of $59.99. Solve for the number of months until the payments are of equal value.
Answer:
10 months
Step-by-step explanation:
Let x denotes number of months.
Down payment of first TV = $200
Per month payment of first TV = $39.99
Total payment of first TV [tex]=200+39.99x[/tex]
Down payment of second TV = $0
Per month payment of second TV = $59.99
Total payment of second TV [tex]=0+59.99x=59.99x[/tex]
To find number of months until the payments are of equal value,
solve [tex]200+39.99x=59.99x[/tex]
[tex]200+39.99x=59.99x\\200=59.99x-39.99x\\200=20x\\x=\frac{200}{20}\\ x=10[/tex]
So, payments become of equal value after 10 months.

Answer:
x = 3
Step-by-step explanation:
Since the 3 angles in the triangle are equal, then the triangle is equilateral.
Thus the 3 sides are congruent.
Equate any 2 of the sides and solve for x, that is
12x - 13 = 7x + 2 ( subtract 7x from both sides )
5x - 13 = 2 ( add 13 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
