Amelia's mom baked 48 cookies. After Amelia and her friends walk through the kitchen, there are 18 cookies left. what is the percent increase in the number of apps Tan has on his phone
Answers
The percentage decrease in the number of cookies is given by the equation A = 62.5 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage decrease be represented as A
Now , the equation will be
The initial number of cookies = 48 cookies
The final number of cookies = 18 cookies
So , the change in number of cookies = 48 - 18 = 30 cookies
So , the percentage decrease in cookies = ( change in number of cookies / initial number of cookies ) x 100
Substituting the values in the equation , we get
The percentage decrease in cookies A = ( 30/48 ) x 100
On simplifying the equation , we get
The percentage decrease in cookies A = 0.625 x 100
The percentage decrease in cookies A = 62.5 %
Therefore , the value of A is 62.5 %
Hence , the percentage decrease is 62.5 %

Answer:
Mr. Phillips can fill 18 bottles of paint
Step-by-step explanation:
The first thing you should do in this case is to know how many ounces of paint you have:
Painting = 64 + 12 + 32 = 108
Then, to calculate the number of 6-ounce bottles you must divide the total number of ounces by 6:
n = (108) / (6) = 18

Numerator = 0.505 × 10 × 10 × 10 = 505
Denominator = 1 × 10 × 10 × 10 = 1000
Numerator / Denominator = 505 / 1000
The Simplified fraction is
= 505/1000
= 101/200

Answer:
(x-6) (2x+1)
Step-by-step explanation:
1) move everything over to the left side, so subtract 11x and 6.
2x^2 -11x - 6 = 0
2)multiply 2(a term) with -6 (c term)
x^2 -11x -12
3) factor and find what multiples to -12 and adds up to -11. in this case its -12 and positive 1
(x-12) (x+1)
4) divide -12 and 1 by the original a term (2)
(x-6) (x+1/2)
5) move the denominator of 2 over to the x.
(x-6) (2x+1)
Answers
the answer is to factor, make ones
another way is use calculator or long division
so factor and make 1's
exg 2/4=1/2 because 2/4=1/2 times 2/2 and 2/2=1 so 1/2 times 1=1/2 so
100=2 times 2 times 5 times 5
5=5
so 10/5=(2 ties 2 times 5 times 5)/5=(2 times 2 times 5)/1 times 5/5=(2 times 2 times 5)/1 times 1=(20)/1=20
the answer is 20
