scoray [572]

Answer:

32 seconds

Step-by-step explanation:

For some number of seconds (s), Tess's essay length (t) will be ...

t = 42 +1.3s

and Margo's essay length (m) will be ...

m = 122 -1.2s

We will have t > m when ...

t > m

42 +1.3s > 122 -1.2s

2.5s > 80 . . . . . . . . add 1.2s-42

s > 32 . . . . . . . . . . . divide by 2.5

After 32 seconds, Tess's essay will exceed Margo's in length.

CD has endpoints C(-3, 4) and D(1, -2). Find the coordinates<br> of its midpoint.

Natalija [7]

Answer:

Midpoint (-1 , 1)

Step-by-step explanation:

Formula: (midpoint)

Let the point A(x , y) be the midpoint of CD.

$x=\frac{x_c+x_D}{2} =\frac{-3+1}{2} =\frac{-2}{2} =-1$

$y=\frac{x_C + y_D}{2} =\frac{4+(-2)}{2} =\frac{2}{2} =1$

Then

A(-1 , 1)
