on a map with a scale 1:100,000 the distance between two cities is 12cm. what would be the distance between these two cities on

klio [65]

Part 1)

we have

the scale is $1:100,000$

the distance on a map is $12\ cm$

we know that

The scale is equal to the distance on a map divided by the real distance

Let

x------> distance on a map

y-------> real distance

S-------> scale

$S=\frac{x}{y}$

In this part we have

$S=\frac{1}{100,000}$

$x=12\ cm$

Find the value of y

$y=\frac{x}{S}$

Substitute the values

$y=\frac{12}{(1/100,000)}$

$y=1,200,000\ cm$

Convert to kilometers

$y=12\ Km$

Part 2)

In this part we have

$S=\frac{1}{300,000}$

$y=12\ km$

Find the value of x

$x=S*y$

Substitute the values

$x=(1/300,000)*12$

$x=0.00004 Km$

Convert to centimeters

$x=4\ cm$

therefore

the answer is

The distance is $4\ cm$

Five hundred sixth-grade students

viktelen [127]

<h3>The ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1</h3>

<em><u>Solution:</u></em>

Given that,

Five hundred sixth-grade students were surveyed

Which means,

sixth-grade students = 500

125 had traveled on an airplane

<em><u>What is the ratio of total sixth-grade students to the number of students who had traveled on an airplane?</u></em>

Therefore,

total sixth-grade students : students traveled on airplane = 500 : 125

<h3>Ratio = 500 : 125</h3>

Reduce to lowest terms,

Divide both sides by 5

<h3>Ratio = 100 : 25</h3>

Further reduce to simplest terms,

Divide both sides by 25

<h3>Ratio = 4 : 1</h3>

Thus the ratio in three ways are 500 : 125 or 100 : 25 or 4 : 1

Answer:

b) number of flowers.

c) 2830

Step-by-step explanation:

We are given the following in the question:

The number of flowers bloomed is given by the function:

where s is the s is the number of seeds she planted.

The number of seeds planted per week is given by

where w represents the number of weeks.

a) composite function that represents how many flowers Lily can expect to bloom over a certain number of weeks.

The composite function can be written as:

where f(w) gives the number of flowers that bloomed in w weeks.

b) units of measurement for the composite function

The composite functions gives the number of flower that will bloom in w weeks. Thus, the unit of measurement is number of flowers.

c) Number of flowers in 35 weeks.

We put w = 35 in the composite function.

2830 flowers will bloom in 35 weeks.

Thanks
