Step-by-step explanation:
The three ways by which we can find the 75% of 96 -
1 ) Simply multiply and extract 75% of 96 as follows -
= 75/100 * 96
= 72
2) We can write 75% as 3/4 of the total so if we multiply 3/4 with 96 we
will get 75% of 96
= 3/4 * 96
= 72
3) We can also get 75% of 96 by taking out the 1/4 rd of 96 and subtracting
from 96 we get 75% of 96
= 96 - (1/4 * 96)
= 96 - 24
= 72
Answer:
14.
Step-by-step explanation:
All of the data can be included of a range from 73 - 91. They are all close in value. However, 14 is much less than the rest of the data, and is therefore an outlier.
Here,
In Right angle triangle,
base = 12 m
height = 8 m
Now,
◇ Area = 1/2*b*h
= 1/2*12*8
= 48 m^2
In semicircle,
radius = 4 m
Then,
◇Area" = 1/2*22/7*r^
= 1/2*22/7*4*4
= 25.14m^2
Again,
◆Total Area = Right triangle + semicircle
= (48+25.14) m^2
= 73.14 m^2
This is right answer...

El saco tiene un precio original de 400 soles.
<h3>¿Cómo determinar el precio inicial de un saco comprado con descuento?</h3>
En este problema tenemos el caso de un precio de compra (P'), en soles, que es resultado de aplicar dos descuentos consecutivos al precio original del saco (P), en soles. El precio es el resultado de multiplicar el precio original por los dos factores de porcentaje, descrito por la siguiente fórmula:
P' = P · (1 - r₁ / 100) · (1 - r₂ / 100), 0 ≤ r₁, r₂ ≤ 100.
Donde:
- r₁ - Porcentaje del primer descuento.
- r₂ - Porcentaje del segundo descuento.
Si sabemos que P' = 224, r₁ = 30 y r₂ = 20, entonces el precio original del saco es:
224 = (1 - 30 / 100) · (1 - 20 / 100) · P
224 = 0.7 · 0.8 · P
P = 224 /(0.7 · 0.8)
P = 400
El precio original del saco es de 400 soles.
