Answer:

s = 130 degrees

Step-by-step explanation:

decagon has a 1,440 degrees interior angles

equation: 1,440 = s + 1310

to find s, add all the known angles

⇒ s + 150 + 170 + 160 + 130 +120 + 160 + 105 + 160 +155

⇒ s + 1,310

equation:

s + 1310 = 1440

subtract each side by 1310

⇒ s + 1310 - 1310 = 1440 - 1310

⇒ s = 130

A car drives 12 miles north, turns, and then drives 8 miles east. How far is the car from its starting point?

Irina-Kira [14]

Draw a straight line. Label that 8. Perpendicular to that at one of the endpoints, draw a slightly smaller line. Label that 6. Draw another line from the end of 6 to the end of 8. This is x. To find how far the car went, we use the Pythagorean Theorem. a²+b²=c² so (8*8) + (6*6) = ? (64+36)=100 The square root of 100 is 10. The car is 10 miles away for the starting point.

Answer: 360,360

Step-by-step explanation:

The number of permutations of n things of which a are identical, b are identical and so on... :-

$\dfrac{n!}{a!\ b!....}$

Given : A clothing store has a certain shirt in 4 sizes: small, medium, large, and extra large.

If it has 2 small, 3 medium, 6 large, and 2 extra large in stock, then total shirts : $2+3+6+2=13$

Then, the number of orders in which the store can sell all the t-shirts will be :_

$\dfrac{13!}{2!3!6!2!}\\\\=\dfrac{13\times12\times11\times10\times9\times8\times7\times6!}{2\times3\times2\times6!\times2}\\\\=360360$

Hence, the number of orders in which the store can sell all the t-shirts = 360,360
