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 $4\ cm$

It takes Evan 6 3/4 hours to mow 3 lawns. it takes him 2 1/3 hours to mow Mr. Smiths yard and 1 3/4 hours to mow Ms. Lee's yard.

Ratling [72]

Answer: $2\frac{2}{3}\ hours$

Step-by-step explanation:

Given: The total time taken by Evan to mow the 3 lawns = $6\frac{3}{4}=\frac{27}{4}\ \text{hours}$

Time taken by Evan to mow the first lawn = $2\frac{1}{3}=\frac{7}{3}\ \text{hours}$

Time taken by Evan to mow the second lawn = $1\frac{3}{4}=\frac{7}{4}\ \text{hours}$

Now,Time taken by Evan to mow the third lawn = $\frac{27}{4}-\frac{7}{3}-\frac{7}{4}$

⇒Time taken by Evan to mow the third lawn = $\frac{81-28-21}{12}$

⇒Time taken by Evan to mow the third lawn = $\frac{32}{12}=\frac{8}{3}=2\frac{2}{3}\ hours$

Hence, the time taken by Evan to mow the third lawn = $2\frac{2}{3}\ hours$

With an 18% discount, Joan was able to save $13.23 for a coat. What was the original price of the coat?

strojnjashka [21]

Hi there!

First we need to realise that the 18% discount equals John's savings. Therefore 18% of the original price is $13.23.

When we know 18% of the price, we can also find 1% of the total price.

18% = $13.23
Divide both sides by 18.

1% = $0.735
To find the total price, which equals 100%, we know only need to multiply both sides by 100.

100% = $73.50.
Therefore, the original price for the coat is $73.50.

~ Hope this helps you!
