Mathematics
1 answer:
serious [3.7K]2 years ago
3 0

Answer:

357 passengers

Step-by-step explanation:

\frac{x}{420}=\frac{85}{100} (The \frac{85}{100} is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: \frac{x}{21}=\frac{85}{5} which is \frac{x}{21}=17

Finally, multiply 17 by 21 to get x.

Therefore, x=357

Which of the following is the proper name for the figure below?<br> 7<br> Y<br> X
VMariaS [17]

Answer:

B

Step-by-step explanation:

When you look at the triangle look at the 3 vertices. Now look at you answers given and choose one that combines all 3 vertices. You don't want your answer to contain a letter/number that represents the length of a side.

So in this case you don't want M or Y in you answer.

Your answer has to be made up of A X andT.

The only answer that uses AXT is answer B.

Cos^-1(-x)=-Cos^-1x for -1&lt;x&lt;1 TRUE OR FALSE?
VMariaS [17]

We are given

cos^{-1}(-x)=-cos^{-1}(x)

Firstly, we will simplify left side

and we will check whether it is equal to right side

Left side:

Let's assume y left side expression

y=cos^{-1}(-x)

now, we can take cos on both sides

cos(y)=cos(cos^{-1}(-x))

we can simplify it

cos(y)=-x

Right side:

Let's assume y left side expression

y=-cos^{-1}(x)

Multiply both sides by -1

-y=cos^{-1}(x)

now, we can take cos on both sides

cos(-y)=cos(cos^{-1}(x))

we can simplify it

cos(-y)=x

cos(y)=x

we can see that

both sides cos(y) value is different

so, this is FALSE.........Answer
