N P r = (n!)/((n-r)!)
8 P 4 = (8!)/((8-4)!)
8 P 4 = (8!)/(4!)
8 P 4 = (8*7*6*5*4!)/(4!)
8 P 4 = 8*7*6*5
8 P 4 = 1680

The final answer is 1680

12. For triangle MNP shown, find the value of x

amm1812

Answer:

$x=36\°\\\angle P=71 \°,\angle N=73 \°,\angle M=36 \°$

Step-by-step explanation:

Given:

The triangle is shown below.

We know that the sum of all interior angles of a triangle is equal to 180°.

Therefore,

$\angle M+\angle N+\angle P=180 \°\\\\x+2x+1+2x-1=180\°\\\\5x=180\°\\\\x=\frac{180}{5}\\\\x=36\°$

Now, plugging the value of 'x' in each angle measure and determining its values. We get:

$\angle M=x=36\°\\\angle P=2x-1=2(36)-1=72-1=71\°\\\angle N=2x+1=2(36)+1=72+1=73\°$

Therefore, the value of 'x' is 36° and the measure of the three angles are 36°, 71° and 73°.

Please give the measure of NPQ and explain how you got it

anygoal [31]

Answer:

C

Step-by-step explanation:

NQP is a triangle. It has 3 angles given.

We know

<em>sum of 3 angles in a triangle is 180 degrees</em>

<em />

We are Given:

∠N = 2x

∠Q = 2x + 2

∠P = 134

THus, we can write and solve for x first:

∠N + ∠Q + ∠P = 180

2x + 2x + 2 + 134 = 180

4x + 136 = 180

4x = 180 - 136

4x = 44

x = 44/4

x = 11

Now, measure of ∠NQP is 2x + 2, so substituting the value of "x", we have:

2x + 2 = 2(11) + 2 = 22 + 2 = 24 degrees

So,

∠NQP = 24°

Correct answer is C

Cassie’s broker charges her a commission of $4.25 for every ten shares of stock bought or sold. Cassie buys 92 shares of Hyren A

Lemur [1.5K]

The answer is Letter B - $2,850.

Multiply the number of shares to their respective costs per share. Add the results. Get the total number of shares then divide it by 10 before multiplying the result to 4.25. Add the product to the previous total.

Hyren Airlines: 92 shares x 13.70 = 1260.4
Giaco Household Goods: 130 x 3.28 = 426.40
Iwad Records: 126 x 8.06 = 1015.56
Total: 2,702.36
Commission: (92 + 130 + 126) 348 shares / 10 shares = 34.8 x 4.25 = 147.90
Total: 2702.36 + 147.90 = 2,850.26 or 2,850
