Answer:

-3/2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-6-6)/(5-(-3))

m=-12/(5+3)

m=-12/8

simplify

m=-3/2

In ∆DFG, m∠D = 78o and m∠F = 32o. Which lists the sides in order from longest to shortest?

ioda

Answer:

Side FG, Side DF, Side DG

Step-by-step explanation:

The angles of a triangle add up to 180° and since we know 2 of the angles add up to 110° the missing ∠G can be found by subtracting

180°-110°=70°

The opposite side of the largest angle is the largest side. The opposite is also true.

Since the angle from greatest to least is ∠D, ∠G, ∠F then the sides from greatest to least is Side FG, Side DF, Side DG

Write 3.666 as a fraction

xenn [34]

3 = 3/1 = 9/3
0.666 is 2/3
2/3 + 9/3 = 11/3
So 3.666 as a fraction is 11/3.
As a mixed number, it is 3 and 2/3.

How many words of five letters can be created that start with the letter T, contain 2 other consonats and end with 2 vowels? Not

Jet001 [13]

If we're only counting 5 vowels (A, E, I, O, U) and 20 consonants (everything else, minus T), then there are

$\dbinom52=\dfrac{5!}{2!(5-2)!}=10$

ways of picking the vowels, and

$\dbinom{20}2=\dfrac{20!}{2!(20-2)!}=190$

ways of picking the consonants.

We want the word to start with T, and we'll allow any arrangement of the other 4 letters, so that the total number of words is

$4!\dbinom52\dbinom{20}2=\boxed{45,600}$

Keep in mind that this means words like TRIES and TIRES are treated as different.
