How long will it take a rocket traveling at 8 km/s to reach 20 km? (please include the equation)

Answers

Answer 1

Answer:

Step-by-step explanation:

Use the second kinematic formula

[tex]x_f-x_i=V_it+\frac{1}{2}at^2\\20=8t+\frac{1}{2}(9.8)t^2\\4.9t^2+8t-20=0[/tex]

Apply the quadratic formula to solve for time. The negative value does not matter because time cannot be negative, its impossible.

I got a value of t = 1.363 seconds

.Abby, Neil and Dylan share a sum of money in the ratio 2:4:5 Neil receives £60 Work out how much money Dylan receives.

Answers

Answer:

Dylan should receive £75

Step-by-step explanation:

We know that

Abby, Neil, and Dylan share money in the ratios 2:4:5

This means that for every £2 that Abby has, Neil has £4, and Dylan has £5.

From this, we also know that for every £4 that Neil has, Dylan has £5.

Now we know that Neil receives £60

For each group of £4, Dylan will have £5.

Then we need to count how many times £4 is on £60, this is equal to:

£60/£4 = 15

And for each one of these, Dylan should receive £5, this is:

15*£5 = £75
