It would not be 2/8 it would be 1/2. When you add fractions together you don't add the denominator just the numerator and then simplify

Yes she does have enough. Here is why: If you add 1/4 and 1/4, you get 2/8 which is also 1/2. 3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4. So she would have 1/4 left. Absolutely enough to get to her friends house and back. :)

consider the exponential function g(x)=100 x (2). which of the following situations could be modeled by the function?
daser333 [38]
The initial value of 100 that doubles over each interval.
without the answer choices, I can only describe it and give you an example of the graph. 
I'm assuming the function is 100*(2)^x because if it is as listed it would be a quadratic function with a vertical stretch of 100.

Nadya [2.5K]

Answer:

The last guy's height is 69 inches

Step-by-step explanation:

mean=sum of all numbers/number of numbers

There are 5 numbers in the set which means that 65 is the sum of all five numbers divided by 5. To reverse that we multiply 65 by 5 to get the sum of all of the numbers.

65*5=325

325 is the sum of all of the numbers so to find the missing number you add up all of the known numbers in the set and find the difference between that sum and 325.

60+67+65+64=256

325-256=69

The missing guy's height is 69 inches.

So the distance is 6.5 times

So the time is 6.5 times 2hrs
