The regular polygon with an interior angle of 140 degrees has 9 sides. This conclusion can be reached by using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides.
Explanation:
The number of sides in a regular polygon can be determined using the formula for the interior angle of a polygon, which is (n-2)*180/n, where 'n' represents the number of sides. This formula comes from the fact that a polygon can be divided into (n-2) triangles, each of which has angles summing up to 180 degrees.
In this particular case, an interior angle of 140 degrees is given. So we will set up an equation: 140 = (n-2)*180/n. Solving for 'n', we get a value of 9.
Therefore, the regular polygon with an interior angle of 140 degrees has 9 sides.

Three interior angles of a quadrilateral measure 55, 117 and 120 degrees. What is the measure of the fourth interior angle?
4 angles = 360
120 + 117 +55 = 292
360-292 = 68
4th angle = 68 degrees

Find the volume of a cube that will hold sixty-four 4.19 in3 toy bouncy balls. (round to nearest whole number)
we know that
The volume of the ball (sphere) is equal to
[tex]V=\frac{4}{3} \pi r^{3}[/tex]
In this problem we have
[tex]V=4.19\ in^{3}[/tex]
Find the radius of the sphere
[tex]r=\sqrt[3]{\frac{3V}{4\pi}}[/tex]
Substitute the value of V
[tex]r=\sqrt[3]{\frac{3*4.19}{4\pi}}=1\ in[/tex]
for the calculation of the total volume I will assume that each ball is a cube
The volume of each ball is
[tex]V=b^{3}[/tex]
where
b is the diameter of the ball
[tex]b=1*2=2\ in[/tex]
Substitute
[tex]V=2^{3}=8\ in^{3}[/tex] ------> volume of each ball in the shape of cube
so
Multiply by [tex]64[/tex]
[tex]64*8=512\ in^{3}[/tex]
therefore
the answer is
[tex]512\ in^{3}[/tex]
How many diagonals can be drawn from one vertex of a hexagon
Nine diagonals can be drawn from the vertex of a hexagon.
What is diagonal?A diagonal of a polygon is a line segment joining two vertex points, excluding the sides of the polygon.
The formula used to find the number of diagonals of a polygon is
(n(n-3))/2
where n is the number of sides of the polygon.
A hexagon has six sides. So, n=6.
The number of diagonals in a hexagon is given by
(6(6-3))/2=9
Hence, a hexagon has nine diagonals.

the recommended dosage of a drug for pediatric patients is 200 mg per kilogram of a patients weight if janine weights 76lb how much of the drug should she get
To determine the dosage of a drug for Janine, who weighs 76 pounds, convert her weight to kilograms and then multiply by the recommended dose per kilogram. The conversion and the dose calculation led to approximately 6894.6 mg of the drug.
The recommended dosage of a drug for pediatric patients is 200 mg per kilogram of the patient's weight. To calculate the dosage for Janine, who weighs 76 pounds, we first need to convert her weight from pounds to kilograms, as dosages are usually measured in metric units. To do so, we use the conversion factor where 1 kilogram equals 2.20462 pounds.
First, we convert Janine's weight to kilograms:
[tex]\frac{76}{2.20462}[/tex] lb/kg = 34.473 kg roughly.
Next, we calculate the total dosage needed in milligrams by multiplying her weight in kilograms by the dosage per kilogram:
34.473 kg * 200 mg/kg = 6894.6 mg.
Therefore, Janine should receive a dose of approximately 6894.6 mg of the drug.

The temperature of dry ice is −109.3°f−109.3°f. this is 184.9°f184.9°f less than the outside temperature. write and solve an equation to find the outside temperature tt (in degrees fahrenheit).
Final answer:
To find the outside temperature T when the temperature of dry ice is -109.3°F, and it is 184.9°F less than the outside temperature, we simply need to add those two numbers. The outside temperature T is found to be 75.6°F.
Explanation:
The student is asked to find the outside temperature T given that the temperature of dry ice is −109.3°F. The temperature of dry ice is 184.9°F less than the outside temperature. To find the outside temperature, we can set up the following equation:
T = (-109.3°F) + 184.9°F
Now, we simply add the two numbers to solve for T:
T = 75.6°F
The calculation shows that the outside temperature T is 75.6°F.

How many people lost their jobs when minimum wage increased from $12 to $18?
Answer:
15 people lost their jobs when minimum wage increased from $12 to $18
Step-by-step explanation:
When the minimum wage is $12
Then by looking at the given graph :
Number of labors supplied = 33
Number of labors in demand = 33
So, it is an equilibrium wage for the system.
Now, when the minimum wage increased from $12 to $18
From the given graph :
Number of labors supplied = 45
Number of labors in demand = 18
⇒ Number of labors working when wage is $12 = 33
And when the wage is $18, no. of labors working or are in demand = 18
⇒ Number of workers who lost their job = 33 - 18 = 15
Hence, 15 people lost their jobs when minimum wage increased from $12 to $18
