The distance between two cities is 87 km. What is the distance between them on a map drawn at a scale of 1:600,000?
Alexxx [7]

Answer:

<u>The correct answer is 14.5 centimeters on the map would be the distance between these two cities.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance between two cities = 87 kilometers

Scale of the map = 1:600,000

2.  What is the distance between them on a map with that scale?

For finding out the answer to this question, we need to:

A. Convert 87 kilometers to centimeters, that is the average distance measurement of the maps, this way:

87 kilometers = 87,000 meters (multiplying by 10³)

87,000 meters = 8'700,000 centimeters (multiplying by 10²)

B. Now we divide the measurement in centimeters by the scale, this way:

8'700,000/600,000 = 14.5

<u>The correct answer is 14.5 centimeters on the map would be the distance between these two cities.</u>

Every 100 tons of the earth's crust contain about 28 tons of silicon. What is the ratio of the weight of silicon to the weight o
d1i1m1o1n [39]
<h3>Answer:</h3>
  1. 28/100 = 7/25
  2. 100/28 = 25/7
<h3>Explanation:</h3>

The wording "the ratio of A to B" means A/B.

Here, "the ratio of the weight of silicon to the weight of crust" means ...

... (28 tons)/(100 tons)

Canceling common factors (and common units), this is ...

... 28/100 = 7/25

___

Then "the ratio of the weight of crust to the weight of silicon" means ...

... (100 tons)/(28 tons) = 100/28 = 25/7

Two concentric circles are of radii 5 cm and 3 cm. Determine the length of the chord of the larger circle which touches the smal
tangare [24]

Answer:

Let O be the common center of two concentric circles and let AB be a chord of larger circle touching the smaller circle at P join OP

Since OP is the radius of the smaller circle to any chrod of the circle bisects the chord.

∴ AP=BP

In right ΔAPO we have

OA  

2

=AP  

2

+OP  

2

⇒25−9=AP  

2

 

⇒AP  

2

=16⇒AP=4

Now AB=2,AP=2×4=8[∵AP=PB]

hence the length of the chord of the larger circle which touches the smaller circle is 8cm.
