Replace: 18+16+6
Combine like terms: 40
Answer:1331
Step-by-step explanation:
11x11x11= 1331
The formula for the volume of a cylinder is V = πr^2h
From the problem r = 4, h = 21 and you use 3.14 for pi
Volume = 3.14 * 4^2 * 21
Volume = 1055.04 cubic feet
Answer:
Option A is the correct choice.
Step-by-step explanation:
We have been given the system of linear equations written by Draco. We are asked to find Draco's error.
Let us form a system of equations using our given information.
Let m represent the price of one muffin and b represent the cost of one bagel.
We are told that in one hour a bakery sold five muffins and nine bagels for a total of $25.50. We can represent this information in an equation as:
The next hour the bakery sold three muffins and 12 bagels for a total of $28.50. We can represent this information in an equation as:
Now let us see system of equations written by Draco.
We can see that Draco has set the price of 5 muffins and 9 bagels equal to $28.50, which is the price of 3 muffins and 12 bagels.
Therefore, Draco should have set the first equation equal to 25.50 and the second equation equal to 28.50. The correct choice is option A.
The area of a 2D form is the amount of space within its perimeter. The correct option is D.
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the L block will be the sum of the area of A and B. Therefore, the area can be written as,
Area of L block = Area of A + Area of B
= (7×2) units² + (1 × 5) units²
= 14units² + 5units²
= 19units²
Hence, the correct option is D.
