2. A faucet for a 30-gallon bathtub fills at a rate of 3 gallons per minute.

Mathematics
1 answer:
denis-greek [22]3 years ago
6 0

Answer:

20

Step-by-step explanation:

Knowing that it is a 30-gallon bathtub.

And it fills at a rate of 3 gallons per minute.

But also drains 1.5 gallons per minute.

So this is for the first minute.

3 - 1.5 = 1.5

So there will be 1.5 gallons of water in the tub after the first minute.

Now do,

30 ÷ 1.5 = 20

It will take 20 full minutes for the bathtub to fill up.

KengaRu [80]

Complete question :

la distancia entre la tierra y la luna es de 384 392 km. Los astronautas de la Apolo XL salieron el 16 de julio de 1969 desde el Centro Espacial Kennedy y al alcanzaron la orbita el 19 de julio de 1969. Suponiendo que cada dia recorrieron la misma cantidad de kilometros cuantos kilometros recorrieron por dia

Responder:

128130,66 kilometros

Explicación paso a paso:

Dado que:

Distancia entre la tierra y la luna = 384,392 km

Tiempo empleado = (19 de julio - 16 de julio) mismo año = 3 días

Velocidad = distancia / tiempo

El tiempo empleado es (3 * 24) = 72 horas

Por lo tanto,

velocidad = 384,392 / 72

= 5338,7777 kilómetros por hora

Dado que se supone que la distancia recorrida diariamente es la misma m:

El número de kilómetros recorridos por día:

5338,7777 kilómetros por hora * 24

= 128130,66 kilometros

Aleksandr-060686 [28]

For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is

Answer: We are required to find the value of z corresponding to probability 0.8340.

i.e., P(Z

We can find the value of z using the standard normal table.

Using the standard normal table, we have:

z(0.8340)=0.97

Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340

Attached here standard normal table for your reference.
