Use a common denominator write an equivalent fraction for each fraction2/5 and 1/8 wats the common denominator

Answers

The common denominator of 5 and 8 is forty. 
To go about solving this, do this:
2/5 and 1/8
2*8/5*8 and 1*5/8*5
16/40 and 5/40
Hope this helps!! :)
The common denominator would be 40.
You need to multiply 2 by 8, and 5 by 8 to get 16/40.
Then you need to multiply 1 by 5, and 8 by 5 to get 5/40.
The final answers are 2/5 = 16/40 and 1/8 = 5/40.

keisha got a fish tank. It fits on table that is exactly 10 inches wide and 12 inches long. When the tank is filled, it can hold 1,800 cubic inches of water. What is the height of Keisha's fish tank?

Answers

Answer: 15 inches is the height of Keisha's fish tank.

Step-by-step explanation: Basically, multiply your length x width, which is 12 x 10. 12 x 10 = 120.

Next, divide 1800 by 120.

1800 divided by 120 is 15.

So, 15 inches is the height of the fish tank.

3. Find f(x) if x represents a single input digit. What is the domain
of f(x)?

4. Find f-1(x). What is the domain of f-1(x)?

Answers

Answer:

1.  6798 7657 6541 9068.

2. 7658 9864 2076 9866.

3. f(x)=9-x and domain of f(x) is {0,1,2,3,4,5,6,7,8,9}.

4.f^(-1)(x)=9-x and domain of f⁻¹(x) is {0,1,2,3,4,5,6,7,8,9}.

We are given that,

The coding method for the card number is 'Subtract each digit from 9'.

So, we have,

Part 1: The number given is 3201 2342 3458 0931.

So, after subtracting each digit from 9, we have,

The coded number is 6798 7657 6541 9068.

Part 2: The coded number given is 2341 0135 7923 0133.

To find the original number, we will subtract the digits from 9.

The original number is 7658 9864 2076 9866.

Part 3: We have f(x), where x represents the single input digit.

That is, 'x' can have values from {0,1,2,3,4,5,6,7,8,9}.

As, the coded output is the number subtracted from 9.

We get, the function isf(x)=9-x.

So, the domain of f(x) is {0,1,2,3,4,5,6,7,8,9}.

Part 4: We need to find the inverse function.

So, we have, f(x)=9-x i.e. x=9-f(x).

Thus, the inverse function isf^(-1)(x)=9-x

Since, the range of f(x) is the domain of f⁻¹(x).

The domain of f⁻¹(x) is {0,1,2,3,4,5,6,7,8,9}.
