Answer:

nearest hundredth 8.944

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (-9 - -1) = -8

(y2-y1) = (2 - -2) = 4

Square the results and sum them up:

(-8)2 + (4)2 = 64 + 16 = 80

Now Find the square root and that's your result:

Exact solution: √80 = 4√5

Approximate solution: 8.944

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
