in Oak Grove, Erik bought a mattress that was marked down 70% from an original price of $500. If the sales tax in Oak Grove is 8%, what was the total cost of the mattress?
The mattress has a total cost of $24.28
How to determine the total cost for the mattress?From the question, the given parameters are:
Cost of a mattress = $74.95
Markdown = 70%
Sales tax in oak grove = 8%
Using the sales tax and the markdown, the total cost for the mattress is calculated using
Total cost of mattress = Cost of a mattress * (1 + Sales tax) * (1 - Markdown )
Substitute the known values in the above equation
So, we have the following equation
Total cost of mattress = 74.95 * (1 + 8%) * (1 - 70%)
Evaluate the products
Total cost of mattress = 24.28
Hence, the total cost of the mattress is $24.28

2. Ryan is running in a 5-kilometer race. How many feet will he run in the race? Use the conversion rates 5, 280ft = 1mi and 1m i approx 1.61 km. Round to the nearest hundred feet
Answer:
16,400 ft
Step-by-step explanation:
You want to know the number of feet in a 5 km race, rounded to the nearest hundred. You are given conversion factors 5280 ft = 1 mi = 1.61 km.
Unit conversionUnit conversion can be done by multiplying by a conversion factor whose numerator is equal to its denominator, and that cancels unwanted units, replacing them with units you want.
[tex]5\text{ km}=5\text{ km}\times\dfrac{5280\text{ ft}}{1.61\text{ km}}\approx16397.5\text{ ft}\approx\boxed{16,\!400\text{ ft}}[/tex]
__
Additional comment
Both of the given conversions are equal to 1 mile, so their ratio is 1. We put feet on top of the fraction, because that is the unit we want. The km value is in the denominator so the km units in numerator and denominator cancel.
The conversion for km is 1 mi = 1.609344 km (exactly). The actual conversion to ft will give 16,404 76/381 ft. This has a very long repeating decimal fraction.

The value of the part of 20 that is 46% is 9.2.
How to determine the percentage of a number?Percentage is simply a number or ratio expressed as a fraction of 100.
It is expressed as;
Percentage = ( Part / Whole ) × 100%
Given the data in the question;
Percentage = 46%Whole = 20Part = ?Plug the given values into the above formula and solve for the part.
Percentage = ( Part / Whole ) × 100%
46% = ( Part / 20) × 100%
46/100 = ( Part / 20 ) × 100/100
46/100 = ( Part / 20 ) × 1
46/100 = Part / 20
Cross multiply
46 × 20 = Part × 100

-5 < 3x -8 / means greater than or equal to
Answer:
Equation: -5 <3× -8
+8. +8
3 <3x
_ _
3. 3
Answer: 1 = X
Step-by-step explanation:
Equation: -5 <3× -8
First Step: You must add 8 to -8 and move it to both sides. The reason why we do this is because on the left side we have 1 number and on the right side we have 2 numbers. We see that the right side has more numbers than the left, so we must move the -8 turning it to a positive 8 (8-8 cancels each other making 0) and adding the +8 in -8 to -5 as well, since we're adding to both sides.
Second Step: Since we added 8 to -5, it equals 3 now 8-5=3. Changing the equation to 3 <3x. Now we have to divide 3 to both sides as well, because we want the x to be by itself. So, 3 ÷ 3 = 1 and 3x ÷ 3 = x
Results: After our extraordinary calculations we recieve
the answer 1=x

What is Mean?A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set.
Only numerical variables—regardless of whether they are discrete or continuous—can be used to determine the mean. Simply dividing the total number of values in a data set by the sum of all of the values yields it.

2d + 8y = 20 and y = 2
A. (1, 1)
B. 4, 4
C. (1, 2)
D. (2, 2)
Answer:
D
Step-by-step explanation:
2d + 8y = 20
y = 2
substitute y = 2 into the other equation
2d + 8(2) = 20
2d + 16 = 20 ( subtract 16 from both sides )
2d = 4 ( divide both sides by 2 )
d = 2
solution is (2, 2 )
answer-> D. (2,2)
Given,
2d + 8y = 20 .............................................(Equation i)
y = 2 .............................................................(Equation ii)
substituting y = 2 in equation i, we get
2d + 8(2) = 20
2d + 16 = 20
2d = 20 - 16
2d = 4
d = 2
Hence the correct answer would be option D. (2,2)

What is elevation?The elevation is the distance above sea level. They are usually measured in meters or feet.
Let t be the height of the tree, then the length of the shadow will be:
Shadow length = t/tan(α)
where α is the angle of elevation. The difference in shadow lengths is:

peruvian cafe bought ad time on radio station wkoi. during the first four weeks, 4,000 different people heard the spot six times, while 2,000 heard it only three times during the same period. what is the average frequency?
The average frequency of people hearing the spot on the radio station is equal to 5.
Average frequency can be defined as the average number of times an individual is exposed to an Advertising schedule.
Average frequency can be calculated by using the formula;
average frequency = total / n
As 4000 people heard the spot 6 times and 2000 people heard it three times; therefore
n = 4000 + 2000 = 6000
total = number × frequency = (6 × 4000) + (3 × 2000) = 24000 + 6000 = 30,000
Substituting these values in the equation;
average frequency = 30,000 / 6000
average frequency = 5
Hence the average frequency of people hearing the spot on the radio station wkoi is calculated to be 5.
