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.

If they are tangent, the triangles formed will be right triangles.
Check using the Pythagorean theorem:
1) 18² = 14.4² + 11.7²
324 = 207.36 + 136.89
324 ≠344.25 not tangent

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.

What is the population in 2020 of a place that has a population of 4 million people in 2011 and is growing at a rate of 1.3%?
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million

What is the surface area of this triangular pyramid?
___square inches
Answer:
Surface area = 10.7 in.²
Step-by-step explanation:
Surface Area of triangular pyramid = BA + P*L
Base Area (BA) = ½*nh
b = 2 in.
h = 1.7 in.
BA = ½*2*1.7 = 1.7 in.²
Perimeter (P) = 2 + 2 + 2 = 6 in.
Slant height (L) = 3 in.
Plug in the values
Surface Area = 1.7 + ½*6*3
Surface area = 10.7 in.²

Let be a1 = 8 and a2 = 8 [ From question ]
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Thus,the common difference between successive terms in the sequence is 6 .
Answer:
6.
Step-by-step explanation:
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2

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.
2/10 convert to a decimal

0.2 is the answer

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.
