13) John and James live 0.7km apart. If John takes 25cm steps, then how many steps would it take

aleksandrvk [35]

It will take John 2800 steps to walk from his house to James' house

Step-by-step explanation:

First of all we have to convert all the measurements in same unit.

Distance = 0.7 km

As 1 km = 1000 m

0.7*100 = 700m

And

1 m = 100 cm

700*100 = 70000cm

Now,

25 cm = 1 step

$So,\\70000cm = \frac{70000}{25}\\=2800\ steps$

It will take John 2800 steps to walk from his house to James' house

I need the answer to this question.

Pavlova-9 [17]

Answer:

The value of x is 9.

The value of y is 18.

Step-by-step explanation:

The given triangle is a right angled triangle.

We have: $tan(x) = \frac{opp}{adj}$

Therefore, $tan(30) = \frac{x}{9\sqrt{3}}$

Since, $tan(30) = \frac{1}{\sqrt{3}}$

Therefore, we have:

$\frac{1}{\sqrt{3}} = \frac{x}{9\sqrt{3}}$

$\implies x = 9$

Now, 'y' is the hypotenuse.

Use Pythagoras theorem, we have $x^2 + (9\sqrt{3}})^2 = y^2$

Substituting x = 9, we get:

81 + 81(3) = y²

$\implies y^2 = 81 + 243$

$\implies y^2 = 324$

$\therefore y = 18$

Hence, the value of y = 18.
