Answer:

B. 85*

Step-by-step explanation:

1. Understand that a triangle always has the additive degrees of 180.

2. Use x+55+40=180, to isolate x, subtract 55 and 40 from 180.

3. You get x = 85.

If J = 12 then J/3 + 3 What is J

kolbaska11 [484]

Well, you're given that $J=12$ . I think the extra information is extraneous, unless there's something more that you forgot to add.
Hope I could be of some assistance. :)

Given u⃗ =⟨3,4⟩ and v⃗ =⟨1,2⟩. Let m be the magnitude of vector u⃗ . Find u⃗ +mv⃗ .

patriot [66]

Answer:

$\vec u+m\vec v=$

Step-by-step explanation:

Being $\vec u$ =<3,4> and $\vec v$ =<1,2>, we must find

$\vec u+m\vec v$

If m is the magintude of $\vec u$ :

$m=\sqrt{a^{2}+b^{2}}$

Where a and b are the components of $\vec u$

$m=\sqrt{3^{2}+4^{2}}=5$

$\vec u+5\vec v=+5=+=$

umuc stat club must appoint a president. a vice president and a treasurer. There are 8 qualified candidates. How many different

zalisa [80]

The best possible solution for this item is to determine the permutation of 8 taken 3 since there are 3 positions and 8 people are qualified. We will use permutation instead of combination because of the specificity of the positions. That is,
8P3 = 336
Thus, there are 336 ways in which the officers can be selected.
