Answer:
The answer is .
Step-by-step explanation:
When you're rounding up to the "Nearest" all you have to do is find for the thousands place then look to the right of the number. If it's 4 or down, round down. but If it's 5 or up, round up. It's as simple as that. The number to the right of the thousands is 9, so we round up 700,000.
And that will be you're answer!
1) The substitution method. This method is best utilized when one of the variables in one of the equations has a coefficient of 1 or -1, otherwise you will introduce fractions. Substitution can also be used for nonlinear systems of equations.
(2) Linear combinations also called the elimination method, multiplication and addition method, etc... My personal favorite as it can be done efficiently. It generalizes well to larger systems and is the underpinning of various other solution methods.
As the name implies it requires the equations to be linear.
You need to know both and be comfortable switching between them.
Can we get one for the elimination method too?
Also, can you solve the same problem using either of the two techniques?
Answer:
The pattern is that each time, 8 is added. The next 2 numbers are 47, 55.
Step-by-step explanation:
7+8=15
15+8=23
23+8=31
31+8=39
39+8=47
47+8=55
Volume total= ______cubic feet
To find the volume of the greenhouse, calculate the volumes of the cylinder and rectangular prism separately. Then, add the volumes together to find the total volume.
To find the volume of the greenhouse, we need to calculate the volumes of the cylinder and the rectangular prism separately. The volume of a cylinder is given by the formula V = πr^2h, where r is the radius and h is the height. The volume of a rectangular prism is calculated by multiplying the length, width, and height. Once we have the volume of both shapes, we can add them together to find the total volume of the greenhouse.
Let's say the cylinder has a radius of 5 feet and a height of 10 feet. The volume of the cylinder is V = π(5^2)(10) = 250π cubic feet. The rectangular prism has a length of 15 feet, a width of 8 feet, and a height of 10 feet. The volume of the rectangular prism is V = 15 * 8 * 10 = 1200 cubic feet. Finally, the total volume of the greenhouse is 250π + 1200 = 1200 + 250π cubic feet.
