Answer:

To compute 1.92 divided by 6 you can multiply 1.92 by 100, compute the division and finally, divide the result by 100. So, 1.92*100 = 192, which can be represented as 18 tenths and 12 ones. This representation is convenient because both 18 and 12 are multiples of 6. Then, dividing 18 tenths by 6 we get 3 tenths (30), and dividing 12 ones by 6 we get 2 ones (2). The addition of the results of these partial divisions is 30 + 2 = 32, which is the result of 192/6. To get 1.92/6 we need to divide 32 by 100, which is 0.32, and that's the result of 1.92/6.

Find the particular solution that satisfies the differential equation and the initial condition.

Vesnalui [34]

Answer:

1) $y =4x^2 +7$

2) $y =7s^2 -3s^4 +181$

Step-by-step explanation:

Assuming that our function is $y = f(x)$ for the first case and $y=f(s)$ for the second case.

Part 1

We can rewrite the expression like this:

$\frac{dy}{dx} =8x$

And we can reorder the terms like this:

$dy = 8 x dx$

Now if we apply integral in both sides we got:

$\int dy = 8 \int x dx$

And after do the integrals we got:

$y = 4x^2 +c$

Now we can use the initial condition $y(0) =7$

$7 = 4(0)^2 +c, c=7$

And the final solution would be:

$y =4x^2 +7$

Part 2

We can rewrite the expression like this:

$\frac{dy}{ds} =14s -12s^3$

And we can reorder the terms like this:

$dy = 14s -12s^3 dx$

Now if we apply integral in both sides we got:

$\int dy = \int 14s -12s^3 ds$

And after do the integrals we got:

$y = 7s^2 -3s^4 +c$

Now we can use the initial condition $y(3) =1$

$1 = 7(3)^2 -3(3)^4 +c, c=1-63+243=181$

And the final solution would be:

$y =7s^2 -3s^4 +181$

It usually took josh 2/5 of an hour to ride his bike to work. But on Monday, his bike was broken, so he took the bus to work whi

Snezhnost [94]

Answer: taking the bus to work takes 13 minutes longer.

Step-by-step explanation:

It usually took josh 2/5 of an hour to ride his bike to work. This means that the number of hours that it took Josh to ride his bike to work is

2/5 × 60 = 24 minutes

But on Monday, his bike was broken, so he took the bus to work which took 5/8 of an hour. This means that the amount of time that it took Josh spent on the bus to work is

5/8 × 60 = 37.5 minutes

The difference between the time spent riding the bike and time spent on the bus is

37.5 - 24 = 13 minutes

Evaluate 6kg 600g + 3kg 800g

zubka84 [21]

Answer:

10.4kg or 10kg 400 g

Step-by-step explanation:

1kg-1000 grams

600grams-0.6 kg

800 grams=0.8kg

6.6 kg +3.8kg

=10.4kg

or convert it back to the question

so the answer will be 10kg 400g
