Answer:

1/2 teaspoon salt

Step-by-step explanation:

We can make this into a ratio of salt:baking soda

1/8:1/4

now, how many 1/4 will we need to make 1?

If we multiply 1/4 by 4, we get one. So, we should do the same to 1/8!

1/8*2=4/8, or 1/2 teaspoon

6) Two boats set off from X at the same
lord [1]

Answer:

The distance between the two boats after 2.5 hours is 57 m.

Step-by-step explanation:

The distance covered by each boat after 2.5 hours are:

speed = \frac{distance}{time}

distance = speed x time

For boat A, speed = 14 km/h and time = 2.5 hrs.

So that,

distance = 14 x 2.5

              = 35 km

For boat B, speed = 18 km/h and time = 2.5 hrs.

So that,

distance = 18 x 2.5

              = 45 km

The distance between the two boats after travelling 2.5 hours can be determined by applying the cosine rule. Let the distance be represented by x, so that:

a^{2} = b^{2} + c^{2} - 2bc Cos A

x^{2} = 45^{2} + 35^{2} - 2(45 x 35) Cos 90^{o}

   = 2025 + 1225 - 3150 (0)

   = 3250

x = \sqrt{3250}

  = 57.0088

x = 57.0 m

The distance between the two boats after 2.5 hours is 57 m.
