Step-by-step explanation:

Distance around entire school track  = 2232.48 meters

In geometry, the perimeter of a shape is defined as the total length of its boundary. The perimeter of a shape is determined by adding the length of all the sides and edges enclosing the shape. It is measured in linear units of measurement like centimeters, meters, inches, or feet.

Given,

Straight length of the track = 1000 meters on each side

total straight length = 2 × 1000 = 2000 meters

Curves are semicircles on each side having diameter of 74 meters

which makes a complete circle

Perimeter of circle = π × diameter

                               = π × 74 = 232.477856 meters

Total distance in meters = 2000 + 232.477856

                                        = 2232.477856

Hence, 2232.48 meters is the total distance around the entire track.

Answer:

Step-by-step explanation:

The sum of the two adjacent angles is equal to the angle that includes both.

  ∠NBS +∠SBR = ∠NBR . . . . . angle sum theorem

  (12x -4) +42 = (17x +8)

Answer:

[A] x² + 2x

[B] 2x² - 5x

[C] 6x² + 8x

[D] 6x² - 12xy

Explanation:

Apply Distributive Law: a(b + c) = ab + ac

x(x + 2) = xx + x · 2

Simplify:

x² + 2x

Apply Distributive Law: a(b - c) = ab - ac

x(2x - 5) = x · 2x - x · 5

Simplify:

2x² - 5x

Apply Distributive Law: a(b + c) = ab + ac

2x(3x + 4) = 2x · 3x + 2x · 4

Simplify:

6x² + 8x

Apply Distributive Law: a(b - c) = ab - ac

6x(x - 2y) = 6xx - 6x · 2y

Answer:

3/4 cups of Chocolate chips is needed

Step-by-step explanation:

Sara was making a cookies and she needs ½ cup of Chocolate chips and 2/3 cup of sugar. She accidently put in 1 cup of sugar. How many cups chocolate chips does she need now?

From the above question:

2/3 cup of sugar = ½ cup of Chocolate chips

1 cup of sugar = x

Cross Multiply

2/3 cup of sugar × x = ½ cup of Chocolate chips × 1 cup of sugar

x = ½ cup of Chocolate chips × 1 cup of sugar/ 2/3 cup of sugar

x = 1/2 ÷ 2/3

x = 1/2 × 3/2

x = 3/4 cups of Chocolate chips

Therefore, for 1 cup of sugar , 3/4 cups of Chocolate chips is needed

Answer: x=18

Step-by-step explanation:

Answer: 32

Step-by-step explanation:

Answer:

b = 20

Step-by-step explanation:

The computation is shown below

Given that

24+ 6b > 138

where

b = 10

b = 15

b = 20

So if we take b = 10

= 24 + 6(10)

= 24 + 60

= 84

B = 15

= 24 + 6(15)

= 24 + 90

= 114

B = 20

= 24 + 6 (20)

= 24 + 120

= 144

So if we take b = 20 the inequality would be true

Answer:

[tex]y = a + b \\ a = y - b = = = > (i) \\ x = ab + 1 \\ x = (y - b)b + 1 \\ x = yb - {b}^{2} + 1 \\ yb = x + {b}^{2} - 1 \\ y = \frac{1}{b} (x + {b}^{2} - 1)[/tex]

Answer:

ab=x-1

a=y-b

x-1=(y-b)b

X-1/y-b=b
