The scale on a map is 1:30000 what is the actual distance represented by 1 centimetre give your answer in metres the scale on a

Alenkinab [10]

Answer:

A. 1 cm will represent 300 metres in real life.

B. 2.5 inches will represent 15 miles on the road

Step-by-step explanation:

Part A.

The scale on the map is 1: 30000. This means that for every 1 unit drawn on the paper, it actually represents 30,000 units in real life.

To get the actual distance represented by 1 centimetre, we will first have to convert 1 cm to metre. this is because our answer is required in metres.

This will be 1 cm = 0.01 metres

We can no set up the relation.

if 1 unit represents 30,0000 units in real life

0.01 metres will represent x metres in real life.

This will be got by cross multiplying $x= \frac{0.01 \times 30,000}{1}=300 metres$

it will represent 300 metres in real life.

Part B

following the same principle above, we can also set up a relation.

If 1 inch represents 6 miles

2.5 inches will represent x miles on the road.

cross multiplying, we will have

$x= \frac{2.5 \times6}{1}= 15 miles$

2.5 inches will represent 15 miles on the road

Solve for P<br> 6p - 2 - 3p = 4<br><br> Solve for W<br> 7w - 5 = -2w + 22

Stella [2.4K]

Answer:

p=2 w=3

Step-by-step explanation:

6p-2-3p=4 combine like terms. 3p-2=4. add 2 to both sides. 3p=6. divide 6 both sides by 3. p=2

7w-5=-2w+22. Combine like terms on same sides. 7w+2w=5+22. 9w=27. Divide both sides by 9. w=3.

The variable n represents the number of bikes in a shipping container. The weight of the container in pounds, including the

Dovator [93]

Given that :-

→ N represent the number of bikes .

→ Weight of container including bikes is 250+23(n-1) pounds.

To Find :-

→ Weight of container when we have 20 bikes.

Solution :-

→ Weight = 250+23(n-1) pounds

Putting the value of n here .

→ Weight = 250+23(20-1)

→ Weight = 250 +23(19)

→ Weight = 250 + 437

→ Weight of container is 687 pounds.
