1: Morgan is incorrect because 10 to the power of three equals 1000. So 1000 times 2.23 equals 2230. Second one I have absolutely no clue. Sorry if I’m wrong

2. divide the first factors and then subtract the exponents

so 7.488 divided by 3.12 which is 2.4
then -8 - 2 which is -10

put them together and you get 2.4*10^-10

Estimate 23,945 + 46,718 by rounding to the highest place value.
kolbaska11 [484]
The highest place value is in the ten thousand for both of these numbers. Let's round the two numbers first, and then we will add them. Let's round 23,945. So, we need to round to the ten thousand place, so we look at the number behind it (3) and act accordingly.
Remember:
5 or more? Raise the Score
4 or less? Let it Rest
We are looking at the bolded number: 23,945. This number is 4 or less, so we let it rest. So, the new rounded number is 20,000. 
Now let's look at 46,718. So, we need to round to the ten thousand place, so we look at the number behind it (6) and act accordingly. Look at the bolded number: 46,718. This number is 5 or more, so we raise the score. The new rounded number becomes 50,000.
Now, all you have to do is add 20,000+50,000, which is 70,000. Hope this helped!

Which number can each term of the equation be multiplied by to eliminate the decimals before solving? –m + 0.02 + 2.1m = –1.45 –

since the 2 in 0.02 is in the hundredths place, you need to multiply that by 100 to eliminate the decimal, then you would need to multiply the other numbers by 100 as well

Por un tubo de 2.5 cm de diámetro fluye agua con una repidez de 20 cm/s ¿Cuál es el valor del flujo y el gasto del agua?
kompoz [17]

Answer:

El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.

Step-by-step explanation:

El gasto del agua (Q), medido en centímetros cúbicos por segundo, es el flujo que pasa a través del tubo. La ecuación para determinar el gasto es:

Q = \frac{\pi}{4}\cdot D^{2}\cdot v (1)

Donde:

D - Diámetro del tubo, medido en centímetros.

v - Velocidad del flujo, medida en centímetros por segundo.

Si sabemos que D = 2.5\,cm y v = 20\,\frac{cm}{s}, entonces el flujo y gasto del agua es:

Q = \frac{\pi}{4}\cdot (2.5\,cm)^{2}\cdot \left(20\,\frac{cm}{s} \right)

Q \approx 98.175\,\frac{cm^{3}}{s}

El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.
