Answer:
80%
Step-by-step explanation:
Please consider the complete question:
Micah is preparing for a piano recital. He practices for 50 minutes on Monday and 90 minutes on Wednesday. By how much did she increase the time she practiced each day?
We will use percent change formula to solve our given problem.
![\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D%5Cfrac%7B%5Ctext%7BFinal%20value%7D-%5Ctext%7BInitial%20value%7D%7D%7B%5Ctext%7BInitial%20value%7D%7D%5Ctimes%20100%5C%25)
Upon substituting our given values, we will get:
![\text{Percent change}=\frac{90-50}{50}\times 100\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D%5Cfrac%7B90-50%7D%7B50%7D%5Ctimes%20100%5C%25)
![\text{Percent change}=\frac{40}{1}\times 2\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D%5Cfrac%7B40%7D%7B1%7D%5Ctimes%202%5C%25)
![\text{Percent change}=80\%](https://tex.z-dn.net/?f=%5Ctext%7BPercent%20change%7D%3D80%5C%25)
Therefore, Micah had increased the time by 80%.
Answer:
-1/2
Step-by-step explanation:
Formula to find slope is y2-y1/x2-x1
Chose one ordered pair to be the 2 and the other one to be the 1
I chose the 2nd one to be 2.
Plug in the y-value from the 2nd ordered pair to y2 because its the 2.
Plug in the x-value from the 2nd ordered pair to x2 because its the 2.
Now you have 0-y1/5-x1
Do the same thing but for the 1.
Plug in the y-value from the 1st ordered pair to y1 because its the 1.
Plug in the x-value from the 1st ordered pair to x1 because its the 1.
Now you have 0-5/5--5
In this situation, you have 2 minus signs.
2 minus = 1 positive.
Now you have 0-5/5+5
Simplify.
Now you have -5/10.
Simplify.
-1/2.
Hope this helps!
To write 0.233 as a fraction you have to write 0.233 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.233 = 0.233/1 = 2.33/10 = 23.3/100 = 233/1000
So, your answer is 233/1000 in fraction, I don't know if it's right, but just trying to help :)
40/100 (to get 1%)
0.4x12.5=5
So 12.5% of 40 is 5
