Given:
The area model.
The area of the shape is 82 square units.
To find:
The correct equation for the given situation.
Solution:
We know that, area of a rectangle is
The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is
Now, the total area is equation to 82 square units.
Since the required equation is , therefore, the correct option is C.
The answer is A.) 1/4(n-64) because if you distribute the 1/4 onto the parentheses it becomes n/4 - 16 which is equivalent to 1/4 - 16 if n were to equal 1.
Step 1:
Multiply the numbers in parentheses:
(-3 * 2) - (7 * (- 3)) - 10
-6 - (- 21) -10
Step 2:
Equal signs are added:
-6 + 21-10
Step 3:
Make the algebraic sum:
-6 + 21-10 = 5
Answer:
the final result is 5.
Answer:
121625 cubic inches.
Step-by-step explanation:
The first thing is that we must assume that the boxes are cubic, that is, they have all their sides equal.
The small box the side measures 15 inches, they tell us that 30% of the large box, therefore the measurement of the large box would be:
15 * 100/30 = 50
50 inches measures the side of the large box.
Now to calculate the difference it would be:
Small box volume:
15 ^ 3 = 3375 cubic inches
Large box volume:
50 ^ 3 = 125000 cubic inches
The difference would be:
125000 - 3375 = 121625
So the difference is 121625 cubic inches.
