If the measure of one interior angle of a regular polygon is 144 degrees, find
the number of sides
The number of sides in the regular polygon is 2.
Explanation:To find the number of sides in a regular polygon, we can use the formula:
Number of sides = 360 degrees/measure of each interior angle
In this case, the measure of one interior angle is given as 144 degrees. Substituting this value in the formula, we get:
Number of sides = 360 degrees/144 degrees = 2.5
Since the number of sides cannot be a decimal, we round down the answer to the nearest whole number. Therefore, the number of sides of the regular polygon is 2.

The number of sides of a regular polygon with each interior angle measuring 144 degrees is 10.
To find n, we can use the formula for the sum of interior angles of a polygon, which is (n-2) times 180 degrees.
Since we know that each angle measures 144 degrees in this regular polygon, we can set up the equation (n-2)times 180 degrees = n times 144 degrees.
Solving for n gives us:
n times 144 degrees = (n-2) times 180 degrees
n times 144 degrees = 180n - 360 degrees
180n - 144n = 360 degrees
36n = 360 degrees
n = 10.
does the table represent an exponential function?
x 1 2 3 4
y -2 -12 -72 -432
a) yes
b)no
Yes this is an exponential function. One way we can determine this is to notice how each y term is multiplied by 6 to get the next y term
example: -2 times 6 = -12
another example: -12 times 6 = -72
The exponential function that models this data is y = -2*6^(x-1). Note how plugging in x = 1 leads to y = -2. Plugging in x = 2 leads to y = -12, and so on.
Megan baby-sat this weekend. She earned $12 an hour plus an additional $32. If she made a total of $140, how long did she work for?
Megan worked for a total of 9 hours.
Explanation:To find how long Megan worked, we need to subtract the additional amount she earned from the total amount she made. Let's say she worked for x hours. Her earnings can be calculated using the equation:
12x + 32 = 140. Subtracting 32 from both sides, we get 12x = 108. Dividing both sides by 12, we find that x = 9.
Therefore, Megan worked for 9 hours.

Michael washes the Gomez family’s cars once a month they pay him $25 every 3 months for his work at this rate how much will Michael earn in one year ?
So you need to see how many times they get paid in a year. 12 months ÷ by every 3= 4. So then you multiply the $25 by 4. Which equals $100.
Final answer:
Michael will earn $100 in one year by washing the Gomez family's cars, as he is paid $25 every 3 months and there are 4 three-month periods in a year.
Explanation:
The question involves calculating how much Michael will earn in one year from washing the Gomez family's cars. Since Michael is paid $25 every 3 months, we first determine how many 3-month periods are in one year. There are 4 such periods in a year (12 months ÷ 3 months = 4). Therefore, Michael will earn $25 for each of these 4 periods.
To find the total amount Michael will earn in one year, we multiply the amount he earns every 3 months by the number of 3-month periods in a year:
$25 per period × 4 periods per year = $100 per year

How does finding the square root of a number compare to finding the cube root of a number? Use the number 64 in your explanation
Answer:
The square-root of a number has 2 same factors being multiplied to get that number while a cubic-root of a number has 3 same factors being multiplied to get that number. For example, the square-root of 64 is 8 because 8 x 8 is 64. However, the cubic-root of 64 is 4 since 4 x 4 = 16 x 4 = 64.
Step-by-step explanation:
Finding the square-root of a number means finding two same numbers that when multiplied equal one number, while finding the cubic-root of a number means finding three same numbers that when multiplied equal one number. For example, the square-root of 64 is 8 because 8 x 8 is 64. However, the cubic-root of 64 is 4 since 4 x 4 = 16 x 4 = 64.
The square root of a number is found by multiplying it by itself, while the cube root is found by multiplying it by itself three times.
Explanation:Finding the square root of a number is the process of finding a number that when multiplied by itself gives the original number. For example, the square root of 64 is 8, because 8 x 8 = 64.
Finding the cube root of a number is the process of finding a number that when multiplied by itself three times gives the original number. For example, the cube root of 64 is 4, because 4 x 4 x 4 = 64.
So, the main difference is that the square root involves multiplying a number by itself once, while the cube root involves multiplying a number by itself three times.

One of the fastest recorded speeds of an alligator on land is 8.8 m/s. Approximately, what is the speed in kilometers per hour?
The given speed is = 8.8 meter per second
To convert it in kilometer per hour, we will do the following steps:
1 meter = 0.001 km
So, 8.8 meter = 0.0088 km
3600 seconds = 1 hour
1 sec = [tex]\frac{1}{3600}[/tex] hours
now, [tex]\frac{8.8meter}{second} = \frac{0.0088}{\frac{1}{3600} }[/tex]
Now multiplying 0.0088 and 3600
[tex]0.0088*3600[/tex]
= 31.68 km/h

how can you use an array to show the commutative property
Arrays are useful representations of multiplication concepts of the commutative property.
We need to find how can you use an array to show the commutative property.
What is the commutative property?The word 'commutative' originates from the word 'commute', which means to move around. Hence, the commutative property deals with moving the numbers around. So mathematically, if changing the order of the operands does not change the result of the arithmetic operation then that particular arithmetic operation is commutative.
An arrangement of objects, pictures, or numbers in rows and columns is called an array. Arrays are useful representations of multiplication concepts (among other ideas in mathematics).
The commutative property of multiplication can be neatly illustrated using an array. For example, the array above could be read as 2 rows of 6, or as 6 columns of 2. Or the array could be physically turned around to show that 2 rows of 6 have the same number as 6 rows of 2.
Therefore, arrays are useful representations of multiplication concepts of the commutative property.

Solve for y. Note the equal sign. What you do to one side, you do to the other. Isolate the y. Do the opposite of PEMDAS.
First, subtract x from both sides
y²z + x (-x) = b (-x)
y²z = b - x
Next, divide z from both sides
(y²z)/z = (b - x)/z
y² = (b - x)/z
Finally, to fully isolate the x, root both sides
√(y²) = √((b - x)/z)
y = √((b - x)/z)
y = √((b - x)/z) is your answer

The length of the flat screen tv is 5 inches less than 3 times it's width. If the perimeter of the tv is 150 inches, find the dimensions
AS we don't know the width so let consider width=x inches
According to given condition
length = (3x -5) inches
TV screen is rectangular shaped so
Perimeter= 2( length +width) =2{(3x-5)+ (x)} equation 1
also given Perimeter = 150 inches equation 2
comparing equation 1 &2
2{(3x-5)+ (x)} =150
2{3x-5+x} =150
2{4x-5} =150
8x-10 =150
Adding 10 both sides
8x -10 +10 =150+10
8x=160
dividing 8 both sides
8x/8= 160/ 8
x= 20 inches width of screen.
length =( 3x-5) ={3(20) -5}
=60-5
length =55
If the The length of the flat screen tv is 5 inches less than 3 times it's width, and the perimeter is 150 inches, then the dimension of the TV screen = 55 inches by 20 inches
Let the length of flat screen tv be represented by L
Let the width of the flat screen tv be represented by W
Three times the width of the flat TV screen = 3W
The length of the flat screen tv is 5 inches less than 3 times it's width.
L = 3W - 5........................(1)
The TV screen is rectangular in shape
The perimeter of the TV screen is given by the formula:
P = 2(L + W)
The perimeter of the TV is 150 inches
P = 150 inches
150 = 2(L + W)
L + W = 150/2
L + W = 75..........(2)
Substitute equation (1) into equation (2)
3W - 5 + W = 75
Collect like terms
3W + W = 75 + 5
4W = 80
W = 80/4
W = 20
Substitute W = 20 into equation (1)
L = 3W - 5
L = 3(20) - 5
L = 60 - 5
L = 55
The width of the TV screen = 20 inches
The length of the TV screen = 55 inches
The dimension of the TV screen = 55 inches by 20 inches
