Circle A has a diameter of approximately 20 inches and an area of approximately an area of 300 in² Circle B has a diameter of approximately 60 inches Which of these could be the area of circle B? A. About 100 in^2 B. About 300 in^2 C. About 900 in^2 D. About 2700 in^2
Answers
Answer:
D. About 2700 in^2
Step-by-step explanation:
The area of a circle A = πd²/4 where d = diameter of circle.
A/d² = π/4 = k the proportionality constant.
So, A₁/d₁² = A₂/d₂² Now for circle A, Area = A₁ = 300 in² and diameter = d₁ = 20 inches. For circle B, Area = A₂ = unknown and diameter = d₂ = 60 inches.
So, we have
A₁/d₁² = A₂/d₂²
A₂ = A₁d₂²/d₁²
A₂ = A₁(d₂/d₁)²
substituting the values of the variables, we have
A₂ = 300 in²(60 in/20 in)²
A₂ = 300 in²(3)²
A₂ = 300 in²(9)
A₂ = 2700 in²
So, the area of circle B is about 2700 in²

La Corona que herón mando elaborar tenía una masa de 1.5 kg y ocupaba un volumen de 300 cm ¿Era de oro dicha Corona? (Obten la respuesta utilizando el principio de arquímedes)
Answers
Answer:
Esta no es una corona de oro porque la densidad del oro es de 19,3 g / cm ^ 3
Step-by-step explanation:
La densidad de la corona se puede obtener del principio de Arquímedes.
Arquímedes descubrió que la fuerza de empuje hacia arriba sobre un sólido es igual al peso del fluido desplazado. entonces, cuando insertamos la corona en un cilindro de medición con un volumen específico, el volumen de agua desplazado es el volumen de la corona.
Dado que tenemos el volumen de la corona como 300 cm ^ 3 y su masa como 1,5 Kg.
La densidad de la corona = 1500 g / 300 cm ^ 3 = 5 g / cm ^ 3
Esta no es una corona de oro porque la densidad del oro es de 19,3 g / cm ^ 3
Conociendo la masa y el volumen de la corona de Herón, queremos saber si esta estaba hecha de oro o no.
Veremos que los datos proporcionados no coinciden con los que tendría el oro puro.
Sabemos que cada material conocido tiene una dada densidad a una dada temperatura. (Donde densidad es el cociente entre masa y volumen)
Particularmente, sabemos qe el oro tiene una densidad de 19.300 kg/m^3
En este caso, sabemos que la corona tiene una masa de 1.5kg y un volumen de 300cm^3
Notar que las unidades de volumen son diferentes, por lo que devemos cambiarlas:
1m = 100cm
entonces:
1cm = 0.01m
(1cm)^3 = 1cm^3 = (0.01m)^3
Entonces tendremos:
V = 300cm^3 = 0.000001*300 m^3 = 0.0003 m^3
Ahora podemos calcular la densidad como:
D = masa/volumen = 1.5kg/0.0003 m^3 = 5000 kg/m^3
Notar que esto es un tercio de la densidad del oro, asi que no, esto no es oro.

The values of the Ferris wheel.
The Ferris wheel is a ride that is fired by the upright rotating wheel and is able of carrying multiple passengers. The table shows us the value of the height of a car of the Ferris wheel and as it travels in a circular motion. The time and height of the second and meters are given.
Thus the answer is if the car is loaded at 0 s, then people are at the lowest part.
The wheel data shows that in 2 seconds the height of the wheel is about 26 meters and in 16 seconds the height of the wheel is about 6 meters. Thus the car is located at 0s and people are at the lowest height of the wheel.Hence the option C is correct.Learn more about the height of a car.

Sally spent a long time searching for the perfect tree. She could look in 6 stores in 45 minutes. If she shopped for 2 hours, how many stores did she visit?
Answers
Answer:
24
Step-by-step explanation:
Sally visited 16 stores when shopping for 2 hours.
Since Sally could look in 6 stores in 45 minutes. Hence:
Time spent in each store = 45 minutes/6 stores = 7.5 minutes per store.
Given a time of 2 hours = 2 hours * 60 minutes per hour = 120 minutes
Number of stores visited in 2 hours = 120 minute / 7.5 minute per store = 16 stores
Therefore Sally visited 16 stores in 2 hours.

An art teacher has 28 students in her first-period class and 24 students in her second-period class. If almost 30% of the students in these classes are boys, about how many boys are in her first two classes?
A. 36
B. 15
C. 8
D. 7
Answers
C. 8
Explanation:
One way to solve this is to find 30% of each class, 28 and 24.
30% of 28:
28 • 0.30 = 8.4
30% of 24:
24 • 0.30 = 7.2
You can then find the average of these two numbers.
8.4 + 7.2 = 15.6
15.6 ➗ 2 = 7.8
7.8 rounds up to 8
Another way to solve is to first find the average number of people in each class.
28 + 24 = 52
52 ➗ 2 = 26
You can then find 30% of this number.
26 • 0.30 = 7.8
7.8 rounds up to 8

The gradient of the line segment in its simplest form is: 1/6.
What is the Gradient of a Line Segment?Gradient of a line segment = slope.Slope (m) = change in y / change in x.Given the following points, (-4,-5) and (2,-4) are on a line segment:
Gradient (m) = change in y / change in x
