Question

Who can help me with these I really need help if u can explain and give answers I will appreciate it.

Answer 1

Hi there! 

Question 6) 

The scale is 1 cm : 18km. 

This means that for every 1 cm, there is 18 km

So, we are going to set it up like a proportion:

cm    1      9
km     18   x

Now we are going to cross multiple: 

1*x=9*18 

Solve for x: 
 x=152

Therefore, the answer is 152 km

question 8) 

Yet again we have a proportion problem. 
 
15    10
18      x

15x=180

x=12ft

Therefore, the answer is 12 feet.


Question 10) 

This question is just like the other one!

3.   6
7.    x

3x=42

x=14

Therefore, the answer is 14 feet
