(10 points)A certain regular polygon has sides of length 10 cm; its apothem is 12.1 cm. The polygon’s area is 484 cm². How many sides does the polygon have

Answers

Answer 1

Answer: There is a mathematical formula which relates these quantities, given by:

$A= (P* a)/(2)$

Using this, we have:

$A= (P* a)/(2) \n 484= ((10n)* 12.1 )/(2) \n \boxed {n=8}$

Your attachment says: (-1/2) · (4x) · (-2) · (7y) · (-1)

Let's put together the
1st, 3rd, and 5th factors: (-1/2) · (-2) · (-1) = -1

So now we have    (-1) · (4x) · (7y)

Well       (4x) · (7y) = (4 · 7) · (x · y) = 28 · x · y

So all together we have    (-1) · (28 · x · y) = -28xy

$\left(-(1)/(2)\right)(4x)(-2)(7y)(-1)\n\n=\left(-(1)/(2)\right)(-2)(4)(7)(-1)(x)(y)\n\n=(1)(4)(7)(-1)(xy)\n\n=(28)(-1)(xy)\n\n=(-28)(xy)\n\n=\boxed{-28xy}\to\boxed{\boxed{A}}$

Through what angle does the minute hand of a clock turn in 12 minutes of time?

Answers

A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute. The minute hand rotates through 360° in 60 minutes or 6° per minute.

Given that j || k, what is the measure of the missing angle?A) 30°
B) 40°
C) 60°
D) 120°

Answers

Answer:

the measure of the missing angle is 60°

Step-by-step explanation:

GIVEN : j || k

solution :

We will use the property of linear pairs

120° + ∠1 = 180° (sum of linear pairs is 180°)

⇒ ∠1 = 180°- 120°

⇒∠1 = 60°

now since j || k

So, we can use corresponding angle properties

So, ∠? = ∠1 (corresponding angles are equal)

⇒∠? = ∠1 = 60°

Thus ? = 60°

60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.
