A cone is 6 cm in height and its vertical angle is 54° calculate the radius of its base.
Please Help It's due soon.
Answer:
7cm
Step-by-step explanation:
The radius of the base of the cone is 4.27 cm.
The vertical angle of a cone is also known as the apex angle. The apex angle of a cone is the angle at the top of the cone, where the slant height and the two radii meet.
The formula for calculating the radius of a cone is:
tan(apex angle) = height / radius
In this case, the apex angle is 54°, the height is 6 cm, and we need to find the radius.
tan(54°) = 6 cm / radius
radius = 6 cm / tan(54°)
radius = 4.27 cm
Therefore, the radius of the base of the cone is 4.27 cm.

Answer:
? ≈ 52.3°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{19}{24}[/tex] , thus
? = [tex]sin^{-1}[/tex] ([tex]\frac{19}{24}[/tex] ) ≈ 52.3° ( to the nearest tenth )
Answer:
≈ 52.3
Step-by-step explanation:
You are given the opposite and hypotenuse side, leading you to use sin. However, since you're trying to find the angle measurement, you use the inverse of sin: [tex]sin^-1[/tex]
Set it up like this:
[tex]sin^-1(\frac{19}{24}) = ?[/tex]
When you solve, you get:
52.34
Round to the nearest tenth:

Carly and Simon are renting formal clothes for a wedding.
They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.
If this information was put into an equation, which amount would represent the y-intercept?
A.
$80
B.
$60
C.
$140
D.
$4,800
Answer:
I think its either B, or C
Step-by-step explanation:
because in a equation your looking for the y intercept and the y intercept is usually the number without x by it.
The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80 thus option (A) is correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given,
They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.
Total cost = 80 × number of hours + fixed cost
y = 86x + 80
y-intercept , x = 0
y = 60(0) + 80
y = 80
Hence"The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80".

8. A bag of Skittles candy contains 8 red, 12 blue, 4 green, and 6 orange. What is
the probability of randomly choosing a green candy, replacing that candy and
choosing another green candy? *
Answer:
it is a 26:4 probability if you simplify it it would be 6.5:1
Step-by-step explanation:
The probability of randomly choosing a green candy, replacing that candy and choosing another green candy is 1/75 and this can be determined by using the given data.
Given :
A bag of Skittles candy contains 8 red, 12 blue, 4 green, and 6 orange.
The following steps can be used in order to determine the probability of randomly choosing a green candy, replacing that candy and choosing another green candy:
Step 1 - First, determine the total number of candies in the bag.
[tex]\rm Total\; Candy = 8 + 12 + 4 +6[/tex]
[tex]\rm Total\; Candy = 30[/tex]
Step 2 - The total number of green candies in the bag is 4.
Step 3 - So, the probability of randomly choosing a green candy, replacing that candy and choosing another green candy is:
[tex]P = \dfrac{4}{30}\times \dfrac{3}{30}[/tex]
Step 4 - Simplify the above expression.
[tex]P = \dfrac{12}{900}[/tex]
[tex]p=\dfrac{1}{75}[/tex]
The probability of randomly choosing a green candy, replacing that candy and choosing another green candy is 1/75.

What is the solution to 4x+6<_18
The manager of a take-out pizza store needs to hire pizza makers and cashiers for the evening shift. The total number of employees of both kinds can be at most 16 and the ratio of cashiers to pizza makers must be at least 3 to 5. Also, each pizza maker can answer 12 phone calls per hour and each cashier can answer 4 calls per hour while the pizza shop must be able to handle at least 72 calls during peak hours.
(a) Create and graph a system of linear inequalities to model this problem
(b) Identify the solution region
(c) If each pizza maker gets $10 per hour and each cashier gets $6 hour, how many
pizza makers and how many cashiers should the manager hire in order to minimize
her cost?
Answer:
a) x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) see picture attached
c) 5 pizza makers and 3 cashiers should be hired.
Step-by-step explanation:
a) Let's define:
x: amount of pizza maker
y: amount of cashier
From conditions in the question:
x + y ≤ 16
y/x ≥ 3/5
12*x + 4*y ≥ 72
b) In the picture attached, the feasible region (also called solution region) is shown.
c) We want to minimize:
10*x + 6*y
subject to the previous restrictions.
It is known that the optimum solution is on the vertex of the feasible region (it is a linear system). Evaluating cost function at each point, we get:
10*1 + 6*15 = 100
10*5 + 6*3 = 68
10*10 + 6*6 = 136
Then, 5 pizza makers and 3 cashiers should be hired.

Solve x2-6x=-5 by completing the square. show ALL work
Have a nice day, be safe and healthy :)
Hope this helped
formula:
(a+b)^2
= a^2+2ab+b^2
Here, we have x^2 (as in a^2)
and -6x (as in 2ab), which, we're missing the b^2
(I'm not really sure how to describe this but bare with me)
-6/2 (-6 is from the -6x) = -3 (the b)
-3^2 = -3*-3 which is equal to 9 (positive 9)
Writing it out -
x^2-6x+9 = -5
- Addition of inequality -
Since we add 9 to the left side, we have to add 9 to the right side; which gives us:
x^2-6x+9=4
Next, lets put the x^2-6x+9 as in (a+b)^2:
(x-3)^2 = 4
Then let's do the square root of equality (square rooting both sides) :
x-3 = 2
Finally lets add 3 to both sides
x = 5
THE ANSWER IS x=5

The point (a, b) is the top of a rectangle. After a transformation, it maps to the point (-a, b+3), what type of transformations happened?
a.) reflection over the line y= -1 and translated 3 units left
b.) reflection over the y = 1 and translated 3 units right
c.) reflection over the x-axis and translated 3 units down
d.) reflection over the y-axis and translated 3 units up
Answer:
d) reflection over the y-axis and translated 3 units up
Step-by-step explanation:
The reflection of the point across the y-axis (x,y)→ (-x,y)
b changed to b+3 so 3 units up
The type of transformation that happened to the rectangle is a reflection over the y-axis and translated 3 units up. Thus, the correct option is D.
What is transformation?The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given that point (a,b) is the top of a rectangle. And after the transformation, the point of the rectangle is (-a, b+3). Therefore,
(a,b) → Reflected over y-axis → (-a,b)(-a,b) → Translated 3 unit up → (-a, b+3)Hence, the type of transformation that happened to the rectangle is a reflection over the y-axis and translated 3 units up. Thus, the correct option is D.
