Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon.
Round to the nearest tenth, if necessary.
Answer:
[tex]\theta = 25.7^\circ[/tex] --- Measure of each exterior angle
[tex]\theta = 154.3^\circ[/tex] --- Measure of each interior angle
Step-by-step explanation:
Given [Missing from the question]
[tex]n = 14[/tex] --- number of sides
Required
- The measure of an exterior angle
- The measure of an interior angle
For an n-sided polygon, the measure of each exterior angle is:
[tex]\theta = \frac{360}{n}[/tex]
Substitute 14 for n
[tex]\theta = \frac{360}{14}[/tex]
[tex]\theta = 25.7^\circ[/tex]
For an n-sided polygon, the measure of each interior angle is:
[tex]\theta = \frac{(n - 2) * 180}{n}[/tex]
Substitute 14 for n
[tex]\theta = \frac{(14 - 2) * 180}{14}[/tex]
[tex]\theta = \frac{12 * 180}{14}[/tex]
[tex]\theta = \frac{2160}{14}[/tex]
[tex]\theta = 154.3^\circ[/tex]
Jade buys a blouse and a skirt for 3/6 of their original price. Jade pays a total of $31 for the two items. If the original price of the blouse is $18, what is the original price of the skirt? Write an equation to represent the situation and use the Distributive Property to solve
Answer:
3/4 times 18= 13.5
31.5-13.5=18
It cost 18 dollars for the skirt with a discount.
It cost 13.5 for the blouse as opposed to the original price of 18 dollars.
18(skirt)+13.5(blouse)=31.5
If you set up a proportion to find the original price of the skirt you will get the answer.
18/x=75/100
75x=18 times 100
75x=1800
75x/75=1800/75
x=24
The original price of the skirt is 24 dollars.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second.
y=-16x^2+174x+78
equation
Answer:
551.06feet
Step-by-step explanation:
Given the equation
y=-16x^2+174x+78
At maximum height, dy/dx = 0
dy/dx = -32x + 174
0 = -32x+174
32x = 174
x = 174/32
x = 5.4375
GEt the maximum height
y=-16x^2+174x+78
y=-16(5.4375)^2+174(5.4375)+78
y = -473.0625 + 946.125 + 78
y = 551.0625
Hence the maximum height is 551.06feet to the nearest hundredth

What is the volume of a sphere with a radius of 6.6 cm, rounded to the nearest tenth of a cubic centimeter?
Volume is a three-dimensional scalar quantity. The volume of a sphere with a radius of 6.6 cm, rounded to the nearest tenth of a cubic centimeter is 1204.3.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of a sphere is given by the formula (4/3)πR³, where R is the radius of the circle. Since the radius of the sphere is 6.6 cm, the volume of the sphere will be,
Volume of Sphere = (4/3) × π × (6.6cm)³ = 1204.26 cm³ ≈ 1204.3³
Hence, the volume of a sphere with a radius of 6.6 cm, rounded to the nearest tenth of a cubic centimeter is 1204.3.

answer has to be in simplest radical form
find s
Answer:
s = 6√3
Step-by-step explanation:
We can recognize that the triangle in the image is a special 30 - 60 - 90 triangle. In a 30 - 60 - 90 triangle, the leg opposite the 60 degree angle, s, is √3 times the leg opposite the 30 degree angle, in this case 6m. We can write an equation to model the situation:
s = 6 * √3
s = 6√3

The expression for the area covered is given as
A= πr^2
Substitute
A= 3.142*40^2
A=3.142*1600
A=5027.2ft^2

In a normal distribution, what percentage of the data falls within 3 standard
deviations of the mean?
O A. 34%
O B. 68%
O c. 99.7%
O D. 95%
Using the Empirical Rule, it is found that the percentage within 3 standard deviations of the mean in the Normal distribution is given by:
c. 99.7%.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.Hence, option C is correct.

In order to add 1 ⁄ 4 and 2 ⁄ 5, the denominators have to be the same. This means multiplying both the numerator and denominator of each fraction by the opposite fraction's denominator.
1 ⁄ 4 + 2 ⁄ 5
( 1 ⁄ 4 × 5 ⁄ 5 ) + ( 2 ⁄ 5 × 4 ⁄ 4 )
(1 × 5)/(4 × 5) + (2 × 4)/(5 × 4)
5 ⁄ 20 + 8 ⁄ 20 = 13 ⁄ 20

What is Function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.
Given, For g(x)=5 and h(x)=2x
[tex]\lim_{x \to \ a }(g(x)*h(x))[/tex]
=> lim (5 * 2x)
=> lim 10x
=> 10a
for G(x)= X-10 And H(x)= 2x,
g(x)/ h(x) = (x - 10)/2x
[tex]\lim_{x \to \ -2} g(x)/ h(x)[/tex]
=> (-2- 10)/-4
=> 3
therefore, the value of function lim (g(x)*h(x)) will be 10 a.
