Answer:

D(5, 4), E(14, 7), M(9.5, 5.5)

Step-by-step explanation:

As AD = 1/4AB and DE ║ AC, the ratio CE/CB = 1/4, or CE = 1/4CB

Find the coordinates of D:

x = 1 + 1/4(17 - 1) = 1 + 4 = 5
y = 5 + 1/4(1 - 5) = 5 - 1 = 4

Find the coordinates of E:

x = 13 + 1/4(17 - 13) = 13 + 1 = 14
y = 9 + 1/4(1 - 9) = 9 - 2 = 7

Find the coordinates of the midpoint M of DE:

x = (5 + 14)/2 = 19/2 = 9.5
y = (4 + 7)/2 = 11/2 = 5.5

Can I have some help?

Answer:

$x = \sqrt{58}$

Step-by-step explanation:

first, you should draw a line to separate the triangle from the rectangle

You can get the height if the triangle by saying 16-9

This will give you 7

The base of the triangle is 3 because the opposite side is given and the opposite sides of a rectangle are equal

Now that we have the measurements of the triangle we can use the Pythagorean theorem

${c}^{2} = {a}^{2} + {b}^{2}$

${x}^{2} = {7}^{2} + {3}^{2}$

${x}^{2} = 49+ 9$

${x}^{2} = 58$

$x = \sqrt{58}$

I just want to make sure: A baseball is traveling (+20 m/s) and is hit by a bat. It leaves the bat traveling (-30 m/s). What is

g100num [7]

Answer:

50m/s

Step-by-step explanation:

We assum the direction the baseball is travelling to the bat is the positive direction at 20 m/s and is hit in the opposite at a faster speed. The change in velocity is the final velocity minus the initial velocity:

$=20-(-30)=50$

The change in velocity is 50m/s

Answer:

3/4

Step-by-step explanation:

1 1/4 * 3/5

Change the mixed number to an improper fraction

1 1/4 = (4*1+1)/4 = 5/4

5/4* 3/5

The 5's cancel

3/4

(SHOW WORK! Need by tomorrow!) Write a system of equations to describe the situation below, solve using substitution, and fill i

Leto [7]

Answer:

1 hour later , 21 pages read

Step-by-step explanation:

x hour later they will read the same number of pages

Tori: 16 + 5x

cora: 13 + 8x

16 + 5x = 13 + 8x

minus 5x each sides: 16 = 13 + 3x

minus 13 each sides: 3 = 3x

divide 3 each sides: x = 1

1 hour later both of them will read 16 + 5 x 1 = 21 pages

check cora: 13 + 8 x 1 = 21

The height of a cone is twice the radius of its base.

Crank

Answer:

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The volume of a cone is given by the formula

$V=\frac{1}{3}\pi r^{2}h$

we have

$h=2x\ units\\r=x\ units$

substitute

$V=\frac{1}{3}\pi x^{2}(2x)$

$V=\frac{2}{3}\pi x^{3}\ units^3$
