A red token is worth twice as much as an orange token. An orange token is worth 5 less a yellow token. A yellow token is worth 1
Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Let r represent red token,

Let o represent orange token,

Let y represent yellow token

Let g represent green token,

A red token is worth twice as much as an orange token. It means that

r = 2o

An orange token is worth 5 less a yellow token. It means that

o = y - 5

A yellow token is worth 15 less than a green token. It means that

y = g - 15

A green token is worth half as much as a blue token. It means that

g = b/2

a blue token is worth B. Therefore, the worth of a yellow token in terms of B would be

Substituting g = B/2 into y = g - 5, it becomes

y = B/2 - 15

Rewrite the following equation in slope-intercept form.<br><br> 3x − 11y = 19
Law Incorporation [45]

Answer:

y = 3/11(x) - 19/11

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

  • 3x-11y-3x=19-3x
  • -11y=-3x+19

Step 2: Divide both sides by -11.

  • -11y/-11=(-3x+19)/-11
  • y=\frac{3}{11}x-\frac{19}{11}

Therefore, the answer is y = 3/11(x) - 19/11.

Determine the volume and the total surface area of the square pyramid.if its perpendicular height is 12cm and square length is 5
Vika [28.1K]

Answer:

Volume = 100 cm³

​Surface area of the square pyramid = 145 cm²

Step-by-step explanation:

Given:

Perpendicular height = 12cm

Square length = 5cm

Find:

Volume

​Surface area of the square pyramid

Computation:

Area of base = side²

Area of base = 5²

Area of base = 25 cm²

Volume = (1/3)(A)(h)

Volume = (1/3)(25)(12)

Volume = 100 cm³

​Surface area of the square pyramid = A + 1/2(P)(h)

Perimeter square pyramid = 4(s)

Perimeter square pyramid = 4(5)

Perimeter square pyramid = 20 cm

​Surface area of the square pyramid = 25 + 1/2(20)(12)

​Surface area of the square pyramid = 145 cm²
