Answer:

h + p ≤ 15

$50h + $500p ≥ $2500

Step-by-step explanation:

The store can ship at most 15 items per day.

The number of items must be 15 or less.

The items are headphones (h) and pianos (p), so, one of the conditions is

h + p ≤ 15

Each headphone is $50, so the money from headphones is $50h.

Each piano is $500, so the money from pianos is $500p.

The total money from headphones and pianos is $50h + $500p.

This money must be at least $2500, that is, it could be $2500 or more .

The second condition is

$50h + $500p ≥ $2500

The two inequalities are

h + p ≤ 15

$50h + $500p ≥ $2500

B and C are <em>wrong</em>, because the store can ship a maximum of 15 items per day.

D is <em>wrong</em>, because the store must make at least $ 2500 per day.

Answer:

<em>x = y = 64° , z = 20°</em>

Step-by-step explanation:

<em>x = y</em> = \frac{180-52}{2} <em>= 64 </em>°

m∠ADC = 52° + x

m∠ADC = 52° + 64° = 116°

<em>z</em> = 180° - 116° - 44° <em>= 20</em> °

Brrunno [24]

The model of the Petronas towers is 4.7 inches taller than the model of the Empire State Building

Step-by-step explanation:

The given is:

  • José made a scale model to compare the Petronas towers, which are 1483 feet tall, to the Empire State Building, which is 1250 feet tall
  • In the model, the empire state building is 25 inches tall

We need to find how much taller than the model of the empire state building is the model of the Petronas towers

∵ The model of the empire state building is 25 inches tall

∵ The Empire State Building is 1250 feet tall

- Let us find the scale drawing

→  inches  :  feet

→  25         :  1250

Divide both sides of ratio by 25

→  1             :  50

That means each 1 inch in the model represents 50 feet in real

∴ The scale drawing is 1 inch : 50 feet

Use this scale to find the model length of Petronas towers

→  inches  :  feet

→  1            :  50

→  x            :  1483

By using cross multiplication

∴ x × 50 = 1 × 1483

∴ 50 x = 1483

- Divide both sides by 50

∴ x = 29.66

∵ x represents the length of Petronas towers model

∴ Petronas towers model is 29.66 inches tall

Now find the difference between the lengths of the two models

∵ The difference = 29.66 - 25 = 4.66 inches

- Round it to the nearest 0.1 inch

∴ The model of Petronas towers is 4.7 inches taller than the

   model of the Empire State Building

The model of the Petronas towers is 4.7 inches taller than the model of the Empire State Building
