Darryl has 2/3 of a bag of dog food. His dog eats 4/9 of a bag per week. How many weeks will the dog food last?
A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.
The number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.
What is a fraction?A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.
We have,
The amount of dog food in the bag = 2/3
The amount of dog food the dog eats per week = 4/9
We need to find the number of weeks that the dog finishes 2/3 of dog food.
The number of weeks:
1 week = 4/9 dog food
Multiply both sides by (9/4 x 2/3)
(9/4 x 2/3) x 1 week = (9/4 x 2/3) x 9/4 dog food
3/2 weeks = 2/3 dog food
[ 3/2 = 1 (1/2) ]
1(1/2) weeks = 2/3 dog food
This means in one and a half weeks the dog finished 2/3 of dog food.
Thus the number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

Two sides of a right triangle are 8 and 12. Find the missing side of 8 and 12 are a leg and a hypotenuse.
Answer:
8.94 if no rounding is necessary.
Step-by-step explanation:
Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...
8² + b² = 12²
64 + b² = 144
Subtract 64 from both sides...
64 - 64 + b² = 144 - 64
b² = 80
[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.

Sophie can type 128 words in three minutes how many minutes will it take her to type 576 words?
Answer:
13 minutes and 30 seconds
Step-by-step explanation:
Okay so first you would divide 128 by 576. But since it takes her 3 minutes just to type 128 words you have to multiply 4.5 times 3. It will take her 13.5 minutes to type 576 words or 13 minutes and 30 seconds.
Reasoning : Why is the numerator greater than
the denominator in a fraction that is equivalent
to a percent greater than 100?
Answer:
See the explanation
Step-by-step explanation:
When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100
example
Numerator >Denominator
=4/2*100
=2*100
=200%
Numerator <Denominator
=2/4*100
=0/5*100
=50%
Juan saved x dollers last month. This month he saved $8 more than 3 times the amount he saved last month. he saved a total of $141 how much did he save last month. Write an equation and solve.
Answer:
he save last month $33.25
Step-by-step explanation:
Let us assume last month saving be x
This month saving be 3x + $8
And, the total would be $141
So based on the above information
The equation is
x + 3x + $8 = $141
4x + $8 = $141
4x = $141 = $8
4x = $133
x = $33.25
Hence, he save last month $33.25
Therefore the same is relevant

Answer:
Ima say the answer is 9, likely she bought 6 more new and with the fire half were destroyed of this 6 new posters only are 3 left so she has 12 posters left that means only 3 are added to how much posters she had before, so in some words she started with 9 also 9+3=12.
For where it says write and equation I think the answer would be something like 9+6-3. In where it says work I want to assume is your explaination so you can use the first paragraph I made. Check Its prob a re do of the work you have done to make sure its right. Coming with "Define the value" Im not sure of this but i think is to define your equation.

Data from a representative sample were used to estimate that 31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with a margin of error of 0.05
Answer:
The required sample size is 329.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.
This means that [tex]\pi = 0.31[/tex]
Confidence level is not given, so we assume 95%.
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?
We need a sample size of n. n is found when M = 0.05. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]
[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]
[tex]n = 328.6[/tex]
Rounding up
The required sample size is 329.
