54 x (2/3) = 36 students were on the bus.

54 - 36 = 18 chaperones were on the bus.

Hope this helps

The​ half-life of​ carbon-14 is 5600 years. If a piece of charcoal made from the wood of a tree shows only 66​% of the​ carbon-1
xz_007 [3.2K]

The tree died about 3357 years ago.

Explanation:

The half life of carbon - 14 is given by

A(t)=A(0)e^{-kt}

where A(t)=0.5

A(0)=1

t=5600

Substituting these values in the above equation, we get,

0.5=1e^{-5600k}

Taking In on both sides of the equation, we get,

   In(0.5)=-5600k

      \frac{In(0.5)}{-5600} =k

0.00012377=k

Since, only 66% of Carbon - 14 remains after the time T.

Thus, we have,

0.66=1e^{-kT}

Taking In on both sides of the equation, we get,

  In(0.66)=-0.00012377 \ T

\frac{In(0.66)}{-0.00012377} =  T

        3357=T

Thus, the tree died about 3357 years ago.

Please help me!<br> Find the value of x
Ira Lisetskai [31]

Answer:

x = 30

Step-by-step explanation:

So we're going to start by finding the other angles of the triangle which x is part of. So we know that a line adds up to 180 degrees. So we can find the angle that's close to N. If you know which one I'm talking about.

105 + 45 = 150. So then we can subtract 150 from 180

180 - 150 = 30

And for the angle at angle L, it's also 90 degrees.

So we know that the angles that add up so far are 120.

Now we'll make an equation:

2x + 120 = 180

Because all angles of a triangle add up to 180

So we subtract 120 from both sides

2x = 60

Now we divide 2 form both sides.

x = 30

So, x = 30

Find the point B on AC such that the ratio of AB to BC is 2:3
Virty [35]

Answer:

B(4, - 3 )

Step-by-step explanation:

We have A(2, - 7) and C(7, 3 )

Using the section formula to calculate the coordinates of B

x_{B} = \frac{3(2)+2(7)}{2+3} = \frac{6+14}{5} = \frac{20}{5} = 4

y_{B} = \frac{3(-7)+2(3)}{2+3} = \frac{-21+6}{5} = \frac{-15}{5} = - 3

Hence B(4, - 3 )
