The remaining honey in the beehive is 4 gallons and 2 quarts, or 4 quarts and 2 ounces.
we need to convert the given measurements to quarts and ounces and then subtract them from the original 5 gallons.
1 gallon is equal to 4 quarts, and 1 quart is equal to 32 ounces.
4 gallons can be converted to quarts by multiplying by 4:
4 gallons × 4 quarts/gallon = 16 quarts
1 pint is equal to 2 cups, and 1 cup is equal to 8 fluid ounces.
1 pint and 2 ounces can be converted to ounces:
1 pint × 2 cups/pint × 8 ounces/cup = 16 ounces
2 ounces (already in ounces) = 2 ounces
Now, let's add up the converted measurements:
16 quarts + 16 ounces + 2 ounces = 16 quarts and 18 ounces
To find the remaining honey, we subtract the converted measurements from the original 5 gallons:
5 gallons - 16 quarts - 18 ounces = 4 gallons and 2 quarts

Answer:
[tex]b=\sqrt{7}[/tex]
Step-by-step explanation:
When we solve for this we should always remember this formula [tex]a^2+b^2=c^2[/tex] and since we already know a and c we can plug that in to find out what b could be but we won't actually solve it.
[tex]a^2+b^2=c^2\\3^2+b^2=4^2\\9+b^2=16\\b^2=7\\\sqrt{b^2}=\sqrt{7}\\b=\sqrt{7}[/tex]
So b would equal whatever the square root of 7 is.

what is the domain of the function a(x) in this context? will mark brainliest if you give right answer
Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.
Pentagon WFNSC is shown on the coordinate grid. Pentagon WFNSC is dilated with the origin as the center of dilation using the rule (x, y)→(3x, 3y) to create pentagon pentagon W'F'N'S'C'. Which statement is true? Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is less than 1. Pentagon W'F'N'S'C' is smaller than pentagon WFNSC because the scale factor is less than 1. Pentagon W'F'N'S'C' is smaller than pentagon WFNSC because the scale factor is greater than 1.
Answer:b
Step-by-step explanation:
Option A. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1.
Transformation of a figure by dilation: If a point (x, y) is dilated by a scale factor 'k', image point will be given by the rule,(x, y) → (kx, ky)
If k > 1, image point will be larger than its preimage. If k < 1, image point will be smaller than its image.Given in the question,
A pentagon WFNSC is dilated following the rule of dilation as,(x, y) → (3x, 3y)
Here, k > 3 which shows that the image will be larger than the preimage.
Therefore, pentagon W'F'N'S'C' will be larger than pentagon WFNSC because the scale factor is greater than 1.
Hence, Option A will be the answer.

One hundred rats with mothers that were exposed to high levels of tobacco smoke during pregnancy were put through a simple maze. At the outset, the maze required the rats to make a choice between going left and going right. Eighty of the tats went right when running the maze for the first time. Assume that the 100 rats can be considered an SRS from the population of all rats born to mothers who were exposed to high levels of tobacco smoke during pregnancy. (Note that this assumption may or may not be reasonable, but researchers often assume that lab rats are representative of large populations because they are often bred to have uniform characteristics.) Let p be the proportion of rats in this population that would go right when running the maze for the first time. Determine a 90% confidence interval for p. Show as much work as is possible.
Answer:
The 90% confidence interval for pis (0.7342, 0.8658).
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].
For this problem, we have that:
100 rats mothers, 80 went right. So [tex]n = 100, \pi = \frac{80}{100} = 0.8[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 - 1.645\sqrt{\frac{0.8*0.2}{100}} = 0.7342[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.8 + 1.645\sqrt{\frac{0.8*0.2}{100}} = 0.8658[/tex]
The 90% confidence interval for pis (0.7342, 0.8658).
An auditorium has 51 rows of seats. The first row contains 70 seats. As you move to the rear of the auditorium, each row has 6 more seats than the previous row.
1. How many seats are in row 12 ,136?
2. How many seats are in the auditorium?
Answer:
seats are in row 12 is 136
seats are in row 136 is 880
seats are in the auditorium is 1071000
Step-by-step explanation:
given data
rows of seat = 51
first row seats = 70
each row seats = 6
to find out
How many seats are in row 12 ,136 and How many seats are in the auditorium
solution
it is AP as 70 , 76 , 82, 88 ............
here A = 70 , d = 6
for n = 12 and 136
so An = a + (n-1)d .........1
A(12) = 70 + (12-1)6
A(12) = 136
and
A(136) = 70 + (136-1)6
A(136) = 880
and
for total seat we get here Sn for 51 row
Sn = [tex]\frac{n}{2}[/tex] × [ 2a(n-1)d] ...........2
put here value
Sn = [tex]\frac{51}{2}[/tex] × [ 2(70)(51-1)6]
Sn = 1071000

Renting video games from Store S costs $2.50 per game plus a monthly fee of $5.00. Renting video games from Store T costs $5.00 per game with no monthly fee. The monthly cost to rent video games depends on the number of video games, v , rented. Which inequality represents the situation when the monthly cost at Store S is less than the monthly cost at Store T?
a.7.5 v 5 v
d.2.5 v + 5 > 5 v
Answer:
2.5v + 5 < 5v is the correct answer.
Step-by-step explanation:
Given that:
Cost to rent one game at store S = $2.50
Monthly fee = $5.00
Let,
v be the number of video games.
Total cost = 2.50v + 5
Cost to rent one game at store T = $5.00
y = 5v
Now,
Store S < Store T
2.50v + 5 < 5v
Hence,
2.5v + 5 < 5v is the correct answer.

Two silos are 25 meters apart. The height of the shorter silo is 23 meters. The angle of
elevation from the shorter silo to the taller silo is 30°. What is the height of the taller silo?
*see attachment for diagram
Answer:
37 m
Step-by-step explanation:
First, use trigonometric ratio to find the distance between the top of the shorter silo to the top of the taller silo.
Let the distance between the top of the smaller silo and the top of the taller silo be x.
Thus, we would have:
Tan 30 = opp/adj = x/25
Tan 30 = x/25
Multiply both sides by 25
25*Tan 30 = x
x = 14 m (nearest meter)
The height of the taller silo = height of the smaller silo + x
= 23 m + 14 m
= 37 m

Answer and Step-by-step explanation:
First off, write the equation in slope intercept form.
y = [tex]-\frac{2}{3} x + 2[/tex]
(3, 0) is the x intercept, so when we go up 2 and left 3 (opposite of the slope, since we want to find the y-intercept), we get a y-intercept of 2.
Now, you put this equation into point-slope form.
Subtract 2 from both sides of the equation.
[tex]y - 2 = -\frac{2}{3} x[/tex]
2 represents [tex]y_{1}[/tex], and the 0 will represent [tex]x_{1}[/tex]. This is because when you plug in 0 for x, you get 2 as the result.
So, the equation should be:
[tex]y - 2 = -\frac{2}{3} (x + 0)[/tex]

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Norma got a score of 84.5; this version has a mean of 67.5 and a standard deviation of 10. Rebecca got a score of 306.5; this version has a mean of 293 and a standard deviation of 27. Morgan got a score of 8.38; this version has a mean of 7.1 and a standard deviation of 0.8. If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job
Answer:
Norma should be offered the job.
Step-by-step explanation:
For Norma;
Population mean; μ = 67.5
Sample mean; x¯ = 84.5
standard deviation; σ = 10
Formula for the test statistic is;
z = (x¯ - μ)/σ
z = (84.5 - 67.5)/10
z = 1.7
For Rebecca;
Population mean; μ = 293
Sample mean; x¯ = 306.5
standard deviation; σ = 27
Formula for the test statistic is;
z = (x¯ - μ)/σ
z = (306.5 - 293)/27
z = 0.5
For Morgan;
Population mean; μ = 7.1
Sample mean; x¯ = 8.38
standard deviation; σ = 0.8
Formula for the test statistic is;
z = (x¯ - μ)/σ
z = (8.38 - 7.1)/0.8
z = 1.6
The person with highest z-score is Norma and as such he should get the job.

1.36 is 17% of x, 1.05 is y% of 15
solve x and y
Answer:
The answers are that x = 8 and y = 7%
Step-by-step explanation:
To find the value of x, we need to divide 1.36 by the percentage it is of the whole (17%).
1.36/17% = 8
And now to find y, we divide 1.05 by 15
1.05/15 = 7%
