Jack picked 10 ears of corn. He and two of his sisters ate two each. What is the amount of corn left represented as a

Burka [1]

<u>ANSWER: </u>

Jack picked 10 ears of corn. The amount of corn left is $\frac{2}{5}$ ears of initial corn.

<u>SOLUTION: </u>

Given, Jack picked 10 ears of corn.

Now the total corn present is 10 ears.

He and two of his sisters ate two each.

Then, remaining corn = 10 ears – eaten corn

= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)

= 10 – 6 = 4

Now, the amount of corn left in fraction is remaining corn divided by initial corn.

Left over corn = $\frac{remaining corn}{initial corn}$

$= \frac{4}{10} = \frac{2}{5}$

Hence, the amount of corn left is $\frac{2}{5}$ ears of initial corn.

Given ΔABC with A(–4, –2), B(4, 4), and C(18, –8), write the equation for the line containing median segment The term is line se

Monica [59]

Here we want to find the equation of the line containing the median CP.

P, being the midpoint of AB can be found using the midpoint formula as:

$\displaystyle{ P=( \frac{-4+4}{2} , \frac{-2+4}{2} )=(0, 1)$ .

The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

$\displaystyle{ m= \frac{y_2-y_1}{x_2-x_1}= \frac{-8-1}{18-0}= \frac{-9}{18}= \frac{-1}{2}$ .

Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

$y-1= \frac{-1}{2}(x-0)\\\\y= -\frac{1}{2}x+1$ .

Answer: $y=-\frac{1}{2}x+1$
