20 and 24 are both divisible by 2, so divide 20 by 2, which equals 10, then divide 24 by 2, which is 12, now our fraction looks like this... 10/12, 10 and 12 are both divisable by 2, so that now equals 5/6, that is the simplest form for this fraction
5.2 grams is larger because 500 centigrams is only 5 grams
Answer:
The family budget to make the one-way trip should be $70.
Step-by-step explanation:
Given: The cost of three gallons of gasoline=$10.50
Therefore, the cost of one gallon of gasoline=
Since, they need 20 gallons for driving out of state to her grandmother’s house.
The cost of 20 gallons of gasoline =
Therefore, The family budget to make the one-way trip should be $70.
Hope this <u><em>Helped!</em></u> :D
Answer:
A)
Decay
B)
Initial value is 5.
C)
The decay factor is 0.75.
D)
75%
Step-by-step explanation:
An exponential function is given by:

Where a is the initial value and r is the rate.
We have the function:

So, a = 5 and r = 1/4.
A)
Remember the guidelines:
- It is exponential growth if r > 1.
- And it is exponential decay if r < 1. (And r must be positive.)
Our rate is 1/4 or 0.25.
It is less than 1, so our function is exponential decay.
B)
The initial value is the value in front of our rate.
So, our initial value in this case is 5.
C)
The decay factor will be 1 - r, where r is our rate.
Since our rate is 0.25, our decay factor is 1 - 0.25 = 0.75.
So, we are decaying by a factor of 0.75.
D)
To convert a decimal to a percent, we move the decimal dot two places to the rght and add a percent sign.
So, 0.75 will be 75.0 % or smply 75%.
It is a 75% decay.
