Answer:
$75
Step-by-step explanation:
50% is half of the total, meaning that we can take half of $50, then add it to 50. Half of 50 is 25, so 50 + 25 = 75 dollars.

Step-by-step explanation:
No doubt you have been shown at least a couple of different strategies for multiplying mixed numbers.
1) Use the distributive property.
10(3 1/6) = 10(3) +10(1/6) = 30 +10/6 = 30 +5/3 = 30 + 1 2/3 = 31 2/3
__
2) Use improper fractions.
10(3 1/6) = 10(19/6) = 190/6 = 95/3 = 31 2/3

At a recent meeting at the American College of Asthma, Allergy, and Immunology, researchers reported that allergy vaccinations are effective in treating sinusitis (inflammation of the membrane lining the facial sinuses) in individuals predisposed to allergies. Specifically, the researchers reported that of individuals predisposed to allergies find relief from their sinusitis after allergy vaccinations. Suppose that this number is accurate and that individuals predisposed to allergies are chosen at random and given allergy vaccinations.
a. Estimate the number of individuals in the random sample who do not find relief from their sinusitis by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable).
b. Quantify the uncertainty of your estimate by giving the standard deviation of the distribution.
What is the algebraic inverse of the function? f(x) = 2x -6 please include steps
9514 1404 393
Answer:
f^-1(x) = (x +6)/2
Step-by-step explanation:
The inverse function is found by solving ...
x = f(y)
Here that is the solution to ...
x = 2y -6
x +6 = 2y . . . . . add 6
(x +6)/2 = y . . . divide by the coefficient of y
The inverse function is ...
f^-1(x) = (x +6)/2

To rent a certain meeting room, a college charges a reservation fee of $13 and an additional fee of $5 per hour. The chemistry club wants to spend less than
$43 on renting the room. What are the possible numbers of hours the chemistry club could rent the meeting room?
Use t for the number of hours.
Write your answer as an inequality solved for t.
Answer:
2 hours or lower
Step-by-step explanation:
$13 + $5t = fee
13 + 15t = 43 --> minus 13 on both sides
15t = 30 --> divide by 15 on both sides
t = 2
Answer: t=6
Explanation:
They want to spend less than $43, 43-13=30 and 30/5=6, Therefore they could have 6 hours max, if the initial reservation fee is $13 and and additional $5 per hour.

f(2) = 3x+1
f(2) = 3*2+1
f(2) = 6+1
f(2) = 7
f(-2) =3x+1
f(-2) =3*-2+1
f(-2) = -6+1

Answer:11.5and 0
Step-by-step explanation:
Assume this is a partial list of financial highlights from a Best Buy annual report (dollars in millions):
Net sales
2020 - $40,580
2019 - $35,475
Earnings before taxes
2020 - $2,291
2019 - $1,313
Net earnings
2020 - $1,378
2019 - $921
Find horizontal analysis and vertical analysis.
Value of Horizontal Analysis:
⇒ Net sales = 14.4%
⇒ Earnings before taxes = 74.4%
⇒ Net earnings = 49.6%
Value of Vertical Analysis;
⇒ Net sales = 100%
⇒ Earnings before taxes = 5.6%
⇒ Net earnings = 3.4%
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Now, We can find as;
Horizontal Analysis:
Here, Calculate the dollar change by subtracting the previous year's figure from the current year's figure for each item:
Net sales = $40,580 million - $35,475 million
= $5,105 million increase
Earnings before taxes = $2,291 million - $1,313 million
= $978 million increase
Net earnings = $1,378 million - $921 million
= $457 million increase
Hence, Calculate the percentage change by dividing the dollar change by the previous year's figure and multiplying by 100 as;
Net sales = ($5,105 million / $35,475 million) x 100
= 14.4% increase
Earnings before taxes = ($978 million / $1,313 million) x 100
= 74.4% increase
Net earnings = ($457 million / $921 million) x 100
= 49.6% increase
And, Vertical Analysis:
Calculate the percentage of each item in relation to the net sales by dividing each item by the net sales and multiplying by 100:
Net sales = $40,580 million / $40,580 million x 100
= 100%
Earnings before taxes = $2,291 million / $40,580 million x 100
= 5.6%
Net earnings = $1,378 million / $40,580 million x 100
= 3.4%
Thus, Value of Horizontal Analysis:
⇒ Net sales = 14.4%
⇒ Earnings before taxes = 74.4%
⇒ Net earnings = 49.6%
Value of Vertical Analysis;
⇒ Net sales = 100%
⇒ Earnings before taxes = 5.6%
⇒ Net earnings = 3.4%

Helpp the topic is about limits
Since we want to find the value of k where the limit exists, set both equations equal to each other. Then substitute x = -1 in for each equation to find k.
[tex]kx - 3 = {x}^{2} + k[/tex]
1. Set both equations equal.
[tex] - k - 3 = 1 + k[/tex]
2. Substitute x = -1.
[tex] - 3 = 1 + 2k[/tex]
3. Solve for k by adding k to both sides. Continue the process of solving the equation.
[tex] - 4 = 2k[/tex]
[tex]k = - 2[/tex]
Thus, k = -2. Check by graphing the function.
