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
When a kite is 22 m above the ground, it makes an angle of 43° with the horizontal. How much string was released? *
Answer:
The length of string = 32.35 meter (Approx.)
Step-by-step explanation:
Given:
Vertical height of kite = 22 meter
Angle with horizontal = 43°
Find:
The length of string
Computation:
Using trigonometry function;
Vertical height of kite [Perpendicular] = 22 meter
The length of string[Hypotenuse]
Sin θ = Perpendicular / Hypotenuse
Sin 43 = 22 / Hypotenuse
0.68 = 22 / Hypotenuse
Hypotenuse = 22 / 0.68
Hypotenuse = 32.35 meter
The length of string = 32.35 meter (Approx.)

32. Ethan cycled from home for r km at 9 km/h to the MRT station. He waited for 3 minutes before catching
the next MRT train. The MRT train travelled at an average speed of 60 km/h. He walked for
2
km at an
Average speed of 6 km/h before reaching his school. The distance from his home to the school by the
above route is 12 km and the total time he spent is 28 minutes.
(Express, in terms of the time he spent cycling from home to the MRT station.
(ii) Find the distance he travelled on the MRT train.
(ii) Form an equation in and solve it.
Answer:
Ethan cycles from home for x km at 9km/h to the MRT station.
He waited for 3 mins before catching the next MRT train.
The MRT train travels at an average speed of 60km/h.
He walks for 1/2km at an average speed of 6km/h before reaching his school.
The distance from his home to the school by the above route is 12km and the total time he spent is 28 mins.
:
(i) Express, in terms of x, the time he spent cycling from home to the MRT station.
time = dist/speed
f(x) = x%2F9
:
(ii) Find the distance travelled by Ethan when he was travelling to school using the MRT
dist by train
d = 12 - x - .5
d = 11.5 - x
(iii) Form an equation in x and solve it.
Subtract the 3 min of waiting, change to hrs: 25/60 = 5%2F12
Write a time equation
bike time + train time + walk time = 5/12 hrs
x%2F9 + %28%2811.5-x%29%29%2F60 + .5%2F6 = 5%2F12
multiply by 180, resulting in
20x + 3(11.5-x) + 30(.5) = 15(5)
20x + 34.5 - 3x + 15 = 75
20x - 3x + 49.5 = 75
17x = 75 - 49.5
17x = 25.5
x = 25.5/17
x = 1.5 km by bike
:
You can confirm this yourself, find the time of each stage of the trip and
the total should be 5/12 hrs which .4167 hrs on a calc

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)
5. Elena drops her pencil in her cup and notices that it just fits diagonally. (See the

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:
[tex]|AC|^2 = |AB|^2 + |BC|^2 \\\\|17|^2 = |15|^2 + |BC|^2 \\\\289 = 225 + |BC|^2 \\\\ |BC|^2 = 289 - 225\\\\ |BC|^2 = 64\\\\ |BC|^2 = \sqrt{64} \\\\BC = 8[/tex]

Step-by-step explanation:
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°
m<Q = 43°

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
97.2 degrees!
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
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

Find the length of c using the Pythagorean thereom
Answer:
c = 13
Step-by-step explanation:
1. Pythagorean theorem states that c^2 = a^2 + b^2
2. In this case, a = 5, b = 12. Therefore, the equation is:
c^2 = 5^2 + 12^2
3. c^2 = 25+144 = 169
4. square root both sides
5. c = 13, c = -13
6. c = 13 since a length cannot be negative.
7. Final answer: C = 13
