13 ➗ 16 equals what? please show me in long divison

1 answer:

3 0

Hi , so we have 13 and 16
16 is bigger than 13 , so we add a 0 to 13.
Now we have 130 divided by 16 , our answer is going to be a decimal because the number 0 was added to the number 13.
We have to find a number that times 16 equals to 130 or a number that is the closest one .
16 times 8 equals to 128 , so 8 is the number that goes after the decimal , then we just keep going.
The final answer is .8125

A pot is being used to boil off 1 kg of water. The specific energy required to cause the phase change is 2297 kJ/kg. Assuming th

Daniel [21]

Answer:

58 seconds

Step-by-step explanation:

Given:

Initial mass of water = 1 kg

Specific energy = 2297 kJ/kg

Heat supplied by the stove = 20 kJ/s

Now,

Half water is to be vaporized i.e 0.5 kg

Thus, heat required for vaporizing 0.5 kg water = mass × specific heat

heat required for vaporizing 0.5 kg water = 0.5 × 2297 = 1148.5 kJ

Therefore,

time taken to provide the required heat = $\frac{\textup{Heat required}}{\textup{Heat supplied per second}}$

time taken to provide the required heat = $\frac{\textup{1148.5 kJ}}{\textup{20 kJ/s}}$

time taken to provide the required heat = 57.425 ≈ 58 seconds

Responder:

Área do campo de futebol = 360m²

Explicação passo a passo:

Dado que :

Comprimento = 24 m

Largura = 15 m

Área do campo = comprimento * largura

Área do campo de futebol = 24m * 15m

Área do campo de futebol = 360m²
