A vessel sails 41 miles S 35° E. How far south has it sailed?

const2013 [10]

Option A: The vessel has sailed 34 miles South

Explanation:

Given that the vessel sails 41 miles S 35° E.

We need to determine the how far south the vessel has sailed.

Let us use the Pythagorean theorem to find the distance of the vessel has sailed.

Thus, we have,

$cos \ \theta=\frac{adj}{hyp}$

Substituting $\theta=35^{\circ}$ , $adj=x$ and $hyp=41$

Hence, we get,

$cos \ 35=\frac{x}{41}$

Simplifying, we have,

$0.82=\frac{x}{41}$

Multiplying both sides by 41, we have,

$33.62=x$

Rounding off to the nearest integer, we have,

$34=x$

Thus, the vessel has sailed 34 miles South.

Therefore, Option B is the correct answer.

In a box 25 cards are there and 1 to 25 numbers are written on them. one card is drawn randomly. what is the probability that it

tensa zangetsu [6.8K]

Explanation :

Given that:

In a box 25 cards are there and 1 to 25 numbers are written on them.

• One card is drawn randomly.

To Find:

• What is the probability that it is multiple of 5.

We know that:

P(E)= F/T

Where,

P(E)= Probability of an event

• F= Favourable outcomes . T = Total outcomes

We have:

F = Number of cards which are multiple of 5

Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.

So, F = 5

T = Total number of cards

• T = 25

P(F) The probabilityP(E) = The probability that it is multiple of 5

Finding the probability that it is multiple of 5:

P(E)= 5/25

P(E)=1/5

Hence,

The probability that it is multiple of 5 is ⅕
