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:
Step-by-step explanation:
The new brakes decrease the probability that a vehicle will collide with another vehicle. Because the anti-lock brakes cut the time it takes a car to stop by 50%, then total collision will be reduced.
But also give drivers an incentive to drive faster, which could potentially increase the number of car accidents.
Because drivers know that the new brakes cut the time it takes to stop and if they drive faster than before, maybe the new brakes won´t be able to reduce accidents and maybe collisions will increase.
Answer:
w = 15 cm
Step-by-step explanation:
We want to find the width, as the area of a rectangle is length (l) * width (w).
Since we know the area and the length, we have 480 = 32w
Isolating w by dividing both sides by 32 gives us w = 15 cm
5=1/2v-3
5=1/2v
+3 +3
8=1/2v
/1/2 /1/2
16=v
Answer:
29 and -18
Step-by-step explanation:
f(x)= -3x+12
f(-9)= -3(-9)+2
f(-9)= 27+2
f(-9)= 29
g(x)= x2
g(-9)= -9(2)
g(-9)= -18
