Mathematics
1 answer:
Paul [167]3 years ago
7 0

Answer:

1:30

Step-by-step explanation:

A building is 10cm tall.

Actual building is 3m tall.

1m = 100cm

3m = How many cm?

Cross multiplying gives:

3 × 100 = 300cm

The scale used here is:

10 cm represents 300cm

or

10:300

Simplifying gives a scale;

1:30

Meaning that 1cm represents 30cm of the actual building.

An airport shuttle service charges $15 plus $1.15 per mile. An equation is written as y=mx+b, where y is the cost for x miles.
Free_Kalibri [48]

Answer: See explanation

Step-by-step explanation:

You didn't really say what you need to calculate but let me try to help out.

From the question, we are informed that an airport shuttle service charges $15 plus $1.15 per mile and that an equation is written as y=mx+b, where y is the cost for x miles.

The equation can be expressed as:

y = 15 + 1.15x

where,

15 = y intercept and this is the initial fixed cost

1.15 = slope and this is the cost per mile

x = number of miles
