Parentheses are used to identify which numbers you should add,multiply .ect first. So If i had
12-(3+1)=x
then you would want to solve 3+1 before you subtract 12.
Answer: 80
Step-by-step explanation:
7824/10 = 782.4
The value represented by 8 is 80 or 8 tens.
If you are comparing the triangles the answer is D
Answer:
Space between 80 evenly spaced chairs = 21m
Step-by-step explanation:
So, according to the given statement, we have the following expression:
No. of chairs ∝ 
70 chairs are 24m apart, so it can be written as:
70 ∝ 
For, 1 chair , we divide both sides by 70
∝ 
1 ∝
-----------------------(Equation 1)
<u>For 80 chairs:</u>
Multiply both sides of <em>Equation.1</em> by 80
80 ∝
80 ∝
So according to the above relation,
<em>80 evenly spaced chairs will have a space of </em><em>21 m</em><em> between them.</em>
The initial measure is:
m1 = 28 ft
The real measure must be:
m2 = 14 ft
The correct procedure to determine the scale factor is:

Dividing both numbers between 14 we have:

Rewriting:
Answer:
Zelie should have divided both numbers by 14.
