The volume of a cone-shaped funnel is 603 cubic centimeters. The radius of the funnel is 8 centimeters. Find the height of the funnel. Round your answer to the nearest whole number.
Answer: 9
Step-by-step explanation:
Volume of cone formula is: pi r^2 h/3
So pi x 8^2 h/3 = 603
H/3 = 2.9991
h = 9 (rounded)
Halla el área de un triángulo equilátero de 54 cm de perímetros
Answer:
Area of equilateral triangle = 81√3 cm²
Step-by-step explanation:
Given:
Perimeter of an equilateral triangle = 54 cm
Find:
Area of equilateral triangle
Computation:
Perimeter of an equilateral triangle = 3 x Side
54 = 3 x Side
Side of equilateral triangle = 54 / 3
Side of equilateral triangle = 18 cm
Area of equilateral triangle = [√3/4]side²
Area of equilateral triangle = [√3/4][18]²
Area of equilateral triangle = [√3/4][324]
Area of equilateral triangle = [√3][81]
Area of equilateral triangle = 81√3 cm²
Which measure of central tendency is the most appropriate to use to compare the most common women's running shoe colour purchased at a shoe store with the most common women's sandal colour purchased?
Answer:
The mode of the data sets
Step-by-step explanation:
The measure of central tendency is a value that aims to give the description of a data set by providing a pointer to the central position of the data set
The item under comparison = The most common women running shoe color and the most common women sandal color
The characteristics of the items under comparison = Color (nominal characteristic)
Therefore, the measure of central tendency will aim to show the frequency with which particular colors are worn, which is represented by the mode of the data set

m∠N = 32°
NQ = 106°
When finding inscribed angles like ∠N with the intercepted arc, the equation is ∠N=1/2MP. (Inscribed angles are always half the degree of the arc length.) Plug in the corresponding value to get ∠N=1/2(64) to get 32°. When finding the angle of the intercepted arc with inscribed angles like NQ, the equation is NQ=2(∠P). Plug in the corresponding value to get 2(53) to get 106°.

In ΔCDE, the measure of ∠E=90°, DE = 39 feet, and CD = 89 feet. Find the measure of ∠C to the nearest degree.
Firstly this shape is an triangle and a triangle has 3 sides/ angles and all angles sum up to 180 degrees...
E = 90 degrees
This explains that it is an hypotenuse triangle so...
answer:
= 39x39 = 1521
= 89x89 = 7921
= 1521 + 7921 = 9442
= square root of 9442 = 97.169954204 rounded off to 97.2

James and Padma are on opposite sides of a 100-ft-wide canyon. James sees a bear at an angle of depression of 45 degrees. Padma sees the same bear at an angle of depression of 65 degrees.
What is the approximate distance, in feet, between Padma and the bear?
A
21.2ft
B
75.2ft
C
96.4ft
D
171.6ft
The approximate distance, in feet, between Padma and the bear will be 75.2 feet. Then the correct option is B.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
James and Padma are on inverse sides of a 100-broad gulch. James sees a bear at a point of discouragement of 45 degrees. Padma sees a similar bear at a point of discouragement of 65 degrees.
Let 'x' be the horizontal distance from bear to Padma. Then the equation is given as,
(tan 45°) (100 - x) = (tan 65°) x
100 - x = 2.1445x
100 = 3.1445x
x = 31.80 feet
Then the approximate distance, in feet, between Padma and the bear will be given as,
cos 65° = 31.80 / d
d = 75.2487
d ≈ 75.2 feet
The approximate distance will be 75.2 feet. Then the correct option is B.

what is the value of x and y *don't simplify into decimal*
Answer:
x = 20
y = 20√2
Step-by-step explanation:
This is a 45 - 45 - 90° special right triangle
In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2
If one leg = 20 then the other leg also = 20
Thus, x = 20
If leg = 20
Then hypotenuse = 20 * √2 or 20√2
Thus, y = 20√2

Inscribed Angle = 1/2 Intercepted Arc
< MQP = 1/2 ( 86)
< MQP = 43
Answer:
43°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the arc it subtends.
m<Q = (1/2)m(arc)MP
m<Q = 1/2 * 86°

Answer:
but where is the diagram
Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall. The diameter of the cup is 8 cm.
What is the Pythagoras theorem?The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
Elena drops her pencil into her cup and notices that it just fits diagonally. The pencil is 17 cm long and the cup is 15 cm tall.
Consider the pencil and cup just make a right angle triangle. If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

a) How much will Sven earn in a 3 hour shift if he sells 24
hamburgers?
b) How many hamburgers must Sven sell to earn $120 in a 6.5 hour
shift? (round to the nearest burger)
Answer:
Part A: $55.50
Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)
Step-by-step explanation:
Part A: $14.50 x 3= $43.50 + 24 x $0.50= $12=
($ earned per hrs x hrs worked)+ ($ per hamburger sold x times amount)
Hence $43.50 + $12= $55.50.
Part B: $14.50 x 6.5 = $94.25 $120 - $94.25= $25.75
($ earned per hrs x hrs worked x x hrs worked) ($ earned - $ earn from shif
$25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)
Hence answer is 52 burgers.

1.) Find the slope of the line represented by the table
2.) Find the y-intercept
need help asap
Answer:
3, 1
Step-by-step explanation:
Slope is rise/run, with the rise being the y increase, and x being the x increase.
Since the run represented is 3, and the rise is 9:
9/3 = 3
The y-intercept is the value of f(x) (which is y) when x = 0
since the equation of the line is:
f(x) = 3x + b
we need to go down 3 units of x since x = 0
3 x 3 = 9
10 - 9 = 1
b = 1
The y-intercept is 1.
