The correct answer is 58/7 (decimal: 8,28....)
This would be so easy for you to solve, in about 3 minutes with a calculator.
A fraction means division ... (the top number) divided by (the bottom number).
Take the fraction part of each choice, do the division for each one,
and see which one gives you 0.4545... repeating.
A). 227/500 = 0.454 That's not 0.45 repeating.
B). 9/20 = 0.45 That's not 0.45 repeating.
C). 5/11 = 0.4545... THAT's 0.4545... repeating !
D). 9/2 = 4.5 That's not 0.45 repeating.
Answer:
The answer for the given function is f( -12 ) = 240.
Step-by-step explanation:
Given:
To Find :
F ( -12 ) = ?
Solution:
Function:
- A function is like a machine that gives an output for a given input.
- A function has an independent variable which is called the input of the function.
- The output for a given input is called the dependent variable.
For Example
f ( x ) = x + 3
x = independent variable
f ( x ) = Output for a given input
Here we have
Therefore f(-12) = 240
Answer:
1. 474
2. 397
Step-by-step explanation:
1. If the three-digit number is xyz, then y = z + 3.
When rounded to the nearest ten and reduced by 320, the result is 150. 150 + 320 = 470, so x = 4. y = 6 if z ≥ 5, and y = 7 if z < 5.
So the number is either 463 or 474. 463 doesn't round to 470, so the answer is 474.
2. If the three-digit number is xyz, then z = x + 4. y is the largest of the three digits; since all the digits are odd, y is either 5, 7, or 9. So z is either 5 or 7, and x is either 1 or 3.
When rounded to the nearest hundred and reduced by 100, the result is 300. 100 + 300 = 400, and y > 5, so xyz is rounded up to 400, which means x = 3. So z = 7 and y = 9.
The answer is 397.
