Given that a rectangle has an area of 345 square millimeters and a base of 15 millimeters, find the height. 
Area of a Rectangle = b x h 
So, to find the height, we would reverse it by dividing the area by the base. 
Work: 
345/15 = 23 
So, 23 would be our height. 
Thus, the height of the rectangle is 23 millimeters.
 
        
                    
             
        
        
        
We are given a scale that for every 1 in on the plan, the actual length will 6.5 ft. 
The maximum distance across the pond on the plan is 9.75 in. So that means we will need to take 6.5 ft 9.75 times. So our answer is 
6.5*9.75=63.375 ft. That's the answer. 
We can visualize this a different way
1 in = 6.5 ft
9.75 in = x ft
And from here it's a little more clear to see what needs to be done. 
Hope this helped! 
 
        
                    
             
        
        
        
Answer:
   =54.25 m^2
Step-by-step explanation:
We will assume the pool is a rectangle
A = l*w
A = (8.75) * (6.2)
   =54.25 m^2
 
        
                    
             
        
        
        
Answer:
1. 37, 2. 1 2/5
Step-by-step explanation:
For Question 1:
Step 1: Replace the x values
x= 3, y=5
Now you get...
9x + 2y --->  (9 x 3) + (2 x 5)    
(Remember, if an x value is beside a number, and it is replaced, that replaced number is to be multiplied with the number the previous x value was.)
Parentheses first, Multiplication second, Addition third (look at PEMDAS below :) )
Step 2: Multiply and Add
(9 x 3) + (2 x 5)
27 + 10
37
For Question 2:
Step 1: Replace the x and y values
m = 1, p = 5
Now your equation should look like this:
m + p ÷ 5 ---> 1 + 2 ÷ 5
Now, which one to do first? Use the PEMDAS strategy
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
You have to do it from top to bottom
Division comes first, which means, you have to divide first, then add:
2 ÷ 5 = 2/5
2/5 + 1 = 1 2/5
Hope this helps :)

The bottom choice is not equal to the original expression because it has an extra x
