Answer:
2,100 cubic feet
Step-by-step explanation:
20 × 15 × 8 = 2,400
20 × 15 × 1 = 300
2,400 - 300 = 2,100
 
        
                    
             
        
        
        
Answer:
The answers to each part are:
Part A.
- <u>The quantity of apples is one-third of the quantity of grapes</u>.
Part B.
- <u>The quantity of apples is a quarter of the quantity of strawberries</u>.
Part C.
- <u>The number of cherries is two-elevenths of the total fruit</u>.
Step-by-step explanation:
To identify the answer in each case, you must remember that all the parts are equal, then:
Part A.
The parts of apples are 1 and the parts grapes are 3, so if you divide the first quantity with the second quantity you obtain:
So, <u>the quantity of apples is one-third of the quantity of grapes</u> or the quantity of apples is three times smaller than the quantity of grapes.
Part B.
The parts of apples are 1 and the parts of strawberries are 4, then you must divide the first quantity with the second quantity:
In this case, <u>the quantity of apples is a quarter of the quantity of strawberries</u> or the quantity of apples is four times smaller than the quantity of strawberries.
Part C.
First, you must add all the part of fruit:
- <em>1 part apple</em>
- <em>1 part orange</em>
- <em>4 parts strawberry</em>
- <em>2 parts cherry </em>
- <em>3 parts grape</em>
The total of fruits is 11 parts, taking into account the quantity of cherries is 2, now you can divide the number of cherries with the total parts of fruit:
- 2 / 11 = 2/11 (two-elevenths)
Now, you can see <u>the number of cherries is two-elevenths of the total fruit</u>.
 
        
             
        
        
        
Answer:
 <em>75.6</em> 
Step-by-step explanation:
100% - 73% = 27%  
27% = 0.27
280 × 0.27 = <em>75.6</em> 
 
        
             
        
        
        
Answer: $70 per year. 
Step-by-step explanation:
Let's say that x is the number of years that has passed and y is how much the stamp is worth. 
So we know that in zero years the stamp was worth $420 because that is the time Sheri gave her brother Sam the stamp. That could bring up the coordinates  (0,420) . 
Now we know that in 8 years it was worth $980 and that could be the coordinates (8,980) 
To find the rate of change we need to find the different between the y value and divide it by the difference in the x values. 
420 - 980 = -560 
  0-8 = -8 
-560/-8 = 70 
The rate of change is 70 which means that it grew by $70 every year.
