19. Perimeter of rectangle = 2(l + b)

l = 25m

b = 16m

Perimeter of rectangular park = 2 (25 + 16)

= 50 + 32

= 82m

Perimeter of square park = 82m

(given that, perimeter of rectangular and square park are equal)

Perimeter of square = 4a

4a = 82

a = 82/4

a = 20.5m

Area of square park = a²

= 20.5²

= 420.25m²

20. Perimeter of regular hexagon = 6a

a = 2.5

6a = 6 × 2.5

= 15cm

21. Perimeter of regular decagon = 10a

a = 8

10a = 10 × 8

= 80cm

Tyler baked 702 cookies. He sold them in boxes of 1i. After selling all the boxes of cookies for the same amount each he earned
ikadub [295]

Answer:

$3.5

Step-by-step explanation:

We have been given that Tyler baked 702 cookies. He sold them in boxes of 18.

First of all we will find the number of boxes of cookies by dividing 702 by 18.

\text{Number of boxes of cookies}=\frac{702}{18}

\text{Number of boxes of cookies}=39

We are told that after selling all the boxes of cookies for the same amount each he earned $136.50. To find the cost of each box we will divide 136.50 by 39.

\text{The cost of one box}=\frac{136.50}{39}

\text{The cost of one box}=3.5

Therefore, the cost of one box of cookies is $3.5.

What is (99/100)^101 times (100/99)^100?
sineoko [7]

Answer:

99/100

Step-by-step explanation:

First of all recall that

a^n\cdot b^n =(ab)^n

Now we we will try to apply that formula for a=99/100 and b=100/99.

First rewrite (99/100)^{101}=(99/100)\times (99/100)^{100}

Now

(99/100)\times (99/100)^{100}\times (100/99)^{100}\\=(99/100)\times ((99/100)\times (100/99))^{100}\\=(99/100)\times 1^{100}\\=(99/100)\times 1\\=99/100
