Answer:
a) la altura es de 1.6 metros
b) contendría 3750 litros
Step-by-step explanation:
1000 litros = 1m³
8000 litros = 8000/1000 = 8m³
La formula del volumen de un prisma rectangular es:
v = área de la base * altura
el área de la base es:
ab = 2.5m * 2m = 5m²
entonces:
v = 5 * altura
v = 8m³
así que:
8m³ = 5m²* altura
altura = 8m³/5m²
altura = 1.6 metros
- Si la altura fuese de 75cm
1 metro = 100 centímetros
75 cms = 75/100 = 0.75 metros
entonces:
volumen = 5m² * 0.75m
volumen = 3.75m³
3.75m³ = 3.75*1000 = 3750 litros
El agua que contendría sería de:
3750 litros
Answer:
2<x<27.6
Step-by-step explanation:
Let the sides of the triangle be x, y and z. For a triangle having the three sides, the following are true:
x+y>z.... 1
x+z>y....2
y+z>x....3
Let z= 14.8 and y = 12.8
Substitute the given values into 1
x+12.8>14.8
x > 14.8-12.8
x>2
Or 2<x
Substituting into equation 3;
14.8+12.8>x
27.6>x or x<27.6
Combine both inequalities
2<x and x<27.6
We will have;
2<x<27.6
Hence the compound inequality is 2<x<27.6
