a square piece of paper is folded in half vertically. if the resulting figure has a perimeter of 12 cm, what was the area of the original square?

Answers

Answer 1
Answer:

The area of original square is 16 centimetre square.

What is an area?

The area is the region bounded by the shape of an object.

Let consider 'a' as the side of the original square.

When it fold vertically then the top and bottom sides will be half of the original side.

The perimeter of folded square = 12 cm

i.e.  (2* 0.5a)+ 2a =3a =12 cm

Then, a=4cm

The area of original square is given by a^2.

Then, a^2 = 4*4 =16

Hence, 16 centimeter is the area of the original square.

Step-by-step explanation:

If total employee benefits are calculated as a percentage of their gross pay, which of the following employees receives the largest amount in total employee benefits?a.
Employee A: gross pay $32,600 , total job benefits $33,600
b.
Employee B: gross pay $32,900 , total job benefits $34,000
c.
Employee C: gross pay $33,400 , total job benefits $33,900
d.
Employee D: gross pay $33,700 , total job benefits $34,700

Answers

we know that

To determine which employee has received the most in employee benefits, it is done by comparing the net amount obtained by subtracting the gross pay from the job benefits obtained.

So

case a) Employee A: gross pay $32,600 , total job benefits $33,600

33,600-32,600=1,000

Find the percentage

by proportion

(32,600)/(100) =(1,000)/(x) \n \n 32,600*x=1,000*100

x=3.067%

case b) Employee B: gross pay $32,900 , total job benefits $34,000

34,000-32,900=1,100

Find the percentage

by proportion

(32,900)/(100) =(1,100)/(x) \n \n 32,900*x=1,100*100

x=3.343%

case c) Employee C: gross pay $33,400 , total job benefits $33,900

33,900-33,400=500

Find the percentage

by proportion

(33,400)/(100) =(500)/(x) \n \n 33,400*x=500*100

x=1.947%

case d) Employee D: gross pay $33,700 , total job benefits $34,700

34,700-33,700=1,000

Find the percentage

by proportion

(33,700)/(100) =(1,000)/(x) \n \n 33,700*x=1,000*100

x=2.967%

therefore

the answer is the option

Employee B: gross pay $32,900 , total job benefits $34,000

Answer:

The answer Is B or employee B.

Suppose theta is in the interval (90, 180). Choose whether the sign of tan(theta/2) is positive or negative.

Answers

90^\circ<\theta<180^\circ\implies45^\circ<\frac\theta2<90^\circ

\tan\theta>0 for \theta in this interval.

Final answer:

When theta is in the interval (90, 180), the sign of tan(theta/2) is negative.

Explanation:

When theta is in the interval (90, 180), the sign of tan(theta/2) is negative.

To understand why, we can use the half-angle identity for tangent:

  1. tan(theta/2) = (-1 - cos(theta))/(sin(theta))
  2. Since theta is in the second quadrant (90 < theta < 180), both sine and cosine are positive.
  3. The numerator (-1 - cos(theta)) is negative, while the denominator (sin(theta)) is positive.
  4. Therefore, the overall expression tan(theta/2) is negative.
