297 is the sum of F and 211
297 = f+211
Answer:
48 , 96
Step-by-step explanation:
You are doubling each number
Answer: You lay out the 3 demential shape into a net then find the area of the net. There are 2 surfaces that are 81 square feet. and 4 surfaces that are 18 feet. 81 + 81 + 18 + 18 + 18 + 18 = 234.
The surface area is 234 Square Feet. Hope this helps and brainliest is always appreciated. :)
Lets make the cost of the algebra textbook = x and the cost of the geometry book = y
2x+3y=64
4x+2y=66
now we get one of these equations in terms of one variable
2x+3y=64 ---> 2x=64-3y ---> x=32-1.5y
now we can plug that numeric value back into the other equation
4(32-1.5y)+2y=66
we can now simplify this equation in order to get the value of y
4(32-1.5y)+2y=66 ---> 128-6y+2y=66 ---> 128-4y=66 ---> -4y=-64 ---> y=16
Answer: Cluster Sampling
Step-by-step explanation:
In cluster sampling, researcher divides the population into groups ,which are called clusters. Then random sample of clusters are chosen ,and researcher conduct study to collect data about the population.
Here each bus is considered a cluster ,because busses are selected at random ,this sampling would be an example of cluster type of sampling.
