Answer:
It's called proportion.
Step-by-step explanation:
The equality of ratios are proportional because like for example 2:3 and 4:9 these two ratios are the same. If you break down 4:9 you will get 2:3. So That's how the term proportional is applied. If we apply these ratio on a triangle they would look the same but just one is small and one is large and we can get it bigger by increasing the ratios. But the difference bwtween the ratios would be same so they are all proportional

The scale drawing of a field in the shape of a triangle is shown below. What is the actual area, in square meters, of this feild?
Answers
Answer:
The area of the field is 70 square meters
Step-by-step explanation:
Given
See attachment for scale drawing
Required
The actual area
From the scale drawing, we have;
[tex]Base = 7[/tex]
[tex]Height = 5[/tex]
So, the area of the scale is:
[tex]Area = 0.5 * Base * Height[/tex]
[tex]Area = 0.5 * 7 * 5[/tex]
[tex]Area = 17.5[/tex] square units
Also from the attached scale,
[tex]1\ unit = 2m[/tex]
So, we have:
[tex]Area = 17.5 * (2m)^2[/tex]
[tex]Area = 17.5 * 4m^2[/tex]
[tex]Area = 70m^2[/tex]
The area of the field is 70 square meters

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that the committee will be made up of all math teachers = total number of maths teacher / total number of teachers

En 3 paquetes iguales hay 24 velitas en total. A) ¿Cuántas habrá en 19 paquetes iguales? B) ¿Cuántos paquetes iguales a estos se podrían armar con 320 velitas?
Answers
Answer:
A) En 19 paquetes habrá 152 velitas.
B) Se podrían armar 40 paquetes iguales con 320 velitas.
Step-by-step explanation:
La regla de tres simple directa consiste en una relación de cantidades con proporcionalidad directa, que se da cuando dadas dos cantidades correspondientes son magnitudes directamente proporcionales. Esto es, si al multiplicar o dividir una de ellas por un número, la otra queda multiplicada o dividida por ese número.
La regla de tres simple permite hallar un cuarto término de una proporción conociendo los otros tres.
Siendo a, b y c datos conocidos y x la incógnita, la regla de tres simple se aplica de la siguiente manera:
a ⇒ b
c ⇒ x
Entonces: [tex]x=\frac{c*b}{a}[/tex]
A) En este caso la regla de tres simple se aplica de la siguiente manera: si en 3 paquetes hay 24 velitas, en 19 paquetes ¿Cuántas velitas habrá?
3 paquetes → 24 velitas
19 paquetes → x
Entonces [tex]x=\frac{19 paquetes*24 velitas}{3 paquetes}[/tex]
x= 152 velitas
En 19 paquetes habrá 152 velitas.
B) En este caso la regla de tres simple se aplica de la siguiente manera: si hay 24 velitas en 3 paquetes, hay 320 velitas ¿Cuántos paquetes se podrán armar?
24 velitas → 3 paquetes
320 velitas → x
Entonces [tex]x=\frac{320 velitas*3 paquetes}{24 velitas}[/tex]
x= 40 paquetes
Se podrían armar 40 paquetes iguales con 320 velitas.

A grocery store collected sales data. It found that when customers buy less bread, they tend to purchase more rice. What can we conclude?
Answers
Answer:
There is a correlation between amount of bread bought and amount of rice purchased. However, there is no causation. This is because there is an increase in the amount of rice purchased with a decrease in the amount of bread bought.
Step-by-step explanation:
We see that there is a correlation between the amount of bread and the amount of rice bought .
When the bread is bought the amount of rice drops and when the amount of bread is decreased the amount of rice increases.
There is no causation meaning there is no direct affect of buying more bread or rice.Buying of rice does not directly cause the purchase of bread.
Hence there is correlation but not causation.
Correlation and causation can occur at the same time when one event causes the other.
Trevor is walking at the rate of 6 kilometers per hour. How many meters does Trevor walk in a minute?
Answers
Answer:
Trevor walks 100 meters in a minute.
Step-by-step explanation:
This question can be solved by proportions.
Trevor is walking at the rate of 6 kilometers per hour.
Each kilometer has 1000 meters, so he walks 6*1000 = 6000 meters per hour.
How many meters does Trevor walk in a minute?
An hour has 60 minutes.
6000/60 = 600/6 = 100
Trevor walks 100 meters in a minute.
