To pay off a $8500 credit card balance with a 15.99% APR in 3 years, you would need to make monthly payments of approximately $293.12.
To determine the monthly payment needed to pay off a credit card balance of $8500 with an APR of 15.99% in 3 years, you can use the formula for calculating monthly payments on a fixed-rate loan. The formula is:
[tex]\[ M = P \times \frac{r(1+r)^n}{(1+r)^n-1} \][/tex]
where:
- [tex]\( M \)[/tex] is the monthly payment,
- [tex]\( P \)[/tex] is the principal balance (credit card balance),
- [tex]\( r \)[/tex] is the monthly interest rate (annual interest rate divided by 12 and converted to decimal),
- [tex]\( n \)[/tex] is the total number of payments (number of months).
First, convert the annual interest rate to a decimal: [tex]\( 15.99\% = 0.1599 \).[/tex]
Next, calculate the monthly interest rate: [tex]\( r = 0.1599 / 12 = 0.013325 \).[/tex]
Now, plug in the values into the formula:
[tex]\[ M = 8500 \times \frac{0.013325(1+0.013325)^{3 \times 12}}{(1+0.013325)^{3 \times 12}-1} \][/tex]
After performing the calculations, the monthly payment [tex](\( M \))[/tex] is approximately $293.12.
A baseball player strikes out three times for every two hits he gets if the player strikes out 15 times how many hits does he get if the player gets 46 hit how many times does he strike out
The player will get 10 hits for 15 times strikes out.
The player will strike out 69 times for 46 hits.
Step-by-step explanation:
Given,
Ratio of strike out to hits = 3:2
Condition 1: If the player gets 15 strikes out;
Let,
x be the hits for 15 times strikes out.
Using proportion;
Strike out : hit :: strike out : hit
[tex]3:2::15:x[/tex]
Product of mean = Product of extreme
[tex]15*2=3*x\\3x=30[/tex]
Dividing both sides by 3;
[tex]\frac{3x}{3}=\frac{30}{3}\\x=10[/tex]
The player will get 10 hits for 15 times strikes out.
Condition 2: if the player gets 46 hits
Let,
y be the strikes out.
Using proportion,
Strike out : hit :: strike out : hit
[tex]3:2::y:46[/tex]
Product of mean = Product of extreme
[tex]2*y=46*3\\2y=138[/tex]
Dividing both sides by 2;
[tex]\frac{2y}{2}=\frac{138}{2}\\y=69[/tex]
The player will strike out 69 times for 46 hits.

Step-by-step explanation:
The previous triangular prism had a surface area of 288 square units. What happens to the surface area of your prism when you double all four measurements?
If all four dimensions of triangular prism having surface area as 288 is doubled than new surface area will be four times than the initial prism that is 1152 square unit.
Solution:Given that
Surface area of a triangular prism = 288 square unit
Need to evaluate new surface area if all four measurement of triangular prism is double.
Relation between surface area and the four dimensions of the triangular prism is given by following formula
Surface Area of triangular prism = bh + 2ls + lb
Where h is height of the prism , b is length of base of the prim , l is length of the prism and s is side length of the prism.
Given that Area of triangular prism = 288 square unit
=> bh + 2ls +lb = 288
Doubling the four dimensions means replace b by 2b, l by 2l , s by 2s and h by 2h in formula of Surface area of triangular prism.
[tex]\text { We get Surface area of new triangular prism }=2 b \times 2 h+2 \times 2 l \times 2 s+2 l \times 2 b[/tex]
[tex]\begin{array}{l}{=4 \times b h+4 \times 2 l s+4 \times l b} \\\\ {=4(b h+2 l s+l b)}\end{array}[/tex]
=> Surface area of new triangular prism = 4 (bh + 2ls +lb)
=> Surface area of new triangular prism = 4 x 288 = 1152 square unit.
Hence we can conclude that if all four dimensions of triangular prism having surface area as 288 is doubled than new surface area will be four times than the initial prism that is 1152 square unit.
Answer: C, the surface area increases by 4 times

A high school drama club is selling tickets to their show. There is a maximum of 400 tickets. The tickets cost $10 (if bought before day of show) and $15 (if bought day of show). Let x represent the number of tickets sold before the day of the show and y represents the number of tickets sold the day of the show. To meet the expenses of the show, the club must sell at least $3500 worth of tickets. The club sells 300 tickets before the day of the show. Is it possible to sell enough additional tickets on the day of the show to meet the expenses of the show? Justify your answer.
Answer:
yes
Step-by-step explanation:
The club can sell 100 more tickets before they reach their maximum. If they sell those at the "day-of" price, they will have additional revenue of ...
100 × $15 = $1500
Then their total revenue would be ...
300 × $10 + $1500 = $4500 . . . . more than enough to meet expenses.
_____
To make up the additional $500 they need, the drama club only needs to sell ...
ceiling($500/$15) = 34 . . . tickets at the "day-of" price.

3 friends share the cost of a gift. The gift costs $70, but the store manager takes $10 off the market price. What amount should they each pay? What is the answer
Answer:
Amount each friend pays for the gift = $20
Step-by-step explanation:
Market price of a gift = $70
The store manager takes $10 off the market price.
Marked down amount = $10
New cost price = Marked price - Marked down amount [tex]=\$70-\$10=\$60[/tex]
The cost of the gift is divided among three friends.

The radius of a circle is increased from 8.008.00 to 8.038.03 m. Estimate the resulting change in area, and then express the estimate as a percentage of the circle's original area. The estimated change in area is nothing msquared2.
Answer:
Step-by-step explanation:
The area of a circle is expressed as
Area = πr^2
Where r = radius of the circle
π = constant = 3.14
The radius of a circle is increased from 8.00800 to 8.03803 m. This means that the original radius of the circle is 8.00800 and the new radius of the circle is 8.03803
Area of original circle =
3.14 × 8.00800^2 = 201.36212096
Area of new circle =
3.14 × 8.03803^2 = 202.87516852203
Increase in area = 202.87516852203 - 201.36212096
= 1.51304756203
Expressing the change as a percentage, it becomes
1.51304756203/201.36212096 ×100
Percentage change = 0.75 %

Select each correct answer. The circles radious increases, The circle moves up, The circle moves left, The circles radious decreases, The circle moves down, The circle movea right.
Answer:
The circles radious increases The circles moves left The circles moves downStep-by-step explanation:
The equation of a circle can be written as [tex](x-a)^2+(y-b)^2=r^2[/tex], where "r" is the radious, and (a,b) are the coordenates in the axis x and b respectively.Then, in the first circle the coordenates are (0,7), which means that the circle will be center there, and the radious is 7 ([tex]\sqrt{49}[/tex]).The second circle have different coordenates: (-5,4), which means that the circle has moved left (from 0 to -7 in the x axis) and down (from 7 to 4 in the y axis). Additionally, its radious has increased from 7 ([tex]\sqrt{49}[/tex], from 8 ([tex]\sqrt{64}[/tex]).See the attached figure please.Then, the correct answers are:The circles radious increases (from r=7 to r=8)The circles moves left (from x=0 to x=-5)The circles moves down (from y=7 to y=4)In his suitcase, Jack has 3 shirts, 4 pants, 2 socks (pairs of socks), and 2 shoes (pairs of shoes).

$12,400 is invested, part at 6% and the rest at 5%. If the interest earned from the amount invested at 6% exceeds the interest earned from the amount invested at 5% by $577.00, how much is invested at each rate? (Round to two decimal places if necessary.) Define variables x and y and set up a system of two linear equations that represents the information given in the problem.
Answer: $10881.81 is invested at 6% and $1518.18 is invested at 5%.
Step-by-step explanation:
Since we have given that
Amount invested = $12400
Rate of interest for first part = 6%
Rate of interest for second part = 5%
Let the amount invested for 6% be 'x'.
Let the amount invested for 5% be 'y'
According to question, we get that
[tex]0.06x-0.05y=577\\\\x+y=12400\\\\\implies x=12400-y[/tex]
So, it becomes,
[tex]0.06(12400-y)-0.05y=577\\\\744-0.06y-0.05y=577\\\\-0.11y=577-744\\\\-0.11y=-167\\\\y=\dfrac{167}{0.11}\\\\y=1518.18[/tex]
x=12400-y=12400-1518.18=$10881.81
Hence, $10881.81 is invested at 6% and $1518.18 is invested at 5%.

The bacterial strain Acinetobacter has been tested for its adhesion properties, which is believed to follow a normal distribution. A sample of five measurements gave readings of 2.69, 5.76, 2.67, 1.62 and 4.12 dyne-cm. Assume that the standard deviation is known to be 0.7 dyne-cm_2 and that the scientists are interested in high adhesion (at least 2.66 dyne-cm^2)(a) Should the alternative hypothesis be one-sided or two-sided? Write down the null and alternative hypotheses.(b) Based on your answer to part (a), test the hypothesis to see if the mean adhesion is at least 2.66 dyne-cm_2 (Use the p-value approach) What can be concluded?
Answer:
a) Alternative hypothesis should be one sided. Because Null and Alternative hypotheses are:
[tex]H_{0}[/tex]: μ=2.66 dyne-cm.
[tex]H_{a}[/tex]: μ<2.66 dyne-cm.
b) the hypothesis that mean adhesion is at least 2.66 dyne-cm is true
Step-by-step explanation:
Let μ be the mean adhesion in dyne-cm.
a)
Null and alternative hypotheses are:
[tex]H_{0}[/tex]: μ=2.66 dyne-cm.
[tex]H_{a}[/tex]: μ<2.66 dyne-cm.
b)
First we need to calculate test statistic and then the p-value of it.
test statistic of sample mean can be calculated as follows:
t=[tex]\frac{X-M}{\frac{s}{\sqrt{N} } }[/tex] where
X is the sample mean M is the mean adhesion assumed under null hypothesis (2.66 dyne-cm) s is the standard deviation known (0.7 dyne-cm_2)N is the sample size(5)Sample mean is the average of 2.69, 5.76, 2.67, 1.62 and 4.12 dyne-cm, that is [tex]\frac{2.69+5.76+2.67+1.62+4.12}{5}[/tex] ≈ 3.37
using the numbers we get
t=[tex]\frac{3.37-2.66}{\frac{0.7}{\sqrt{5} } }[/tex] ≈ 2.27
The p-value is ≈ 0.043. Taking significance level as 0.05, we can conlude that sample proportion is significantly higher than 2.66 dyne-cm.
Thus, according to the sample the hypothesis that mean adhesion is at least 2.66 dyne-cm is true

Weeks hours
Both of the hours cancel out similar to unit conversions in chemistry and you are left with flowers per week. since the value of flowers you get per hour you work, and x is dependant on the amount of hours you work in a week. These two functions work in conjuction to give flowers per week picked, this crossing off happens diagonally from left down to the right.
The units of measurement for the composite function s(W(h)) is Option(C) flowers/week.
What is the given unit of the composite function ?Given that the function s(t) approximates how many flowers Matthew picks per hour.
Unit of function s(t) is flowers/hours.
Also given that the function W(h) represents how many hours per week Matthew spends picking flowers.
Unit of W(h) = hours/week .
The composite function s(W(h)) will have unit -
= Flowers/hours * hours/week

A potato chip manufacturer has found that in the past the standard deviation of bag weight has been 0.2 ounce. They want to test whether the standard deviation has changed. What is the null hypothesis?
Answer:
Null Hypothesis: [tex]\sigma=0.2[/tex]
Alternative hypothesis: [tex]\sigma \neq 0.2[/tex] (Changes on the deviation)
Step-by-step explanation:
s represent the sample standard deviation
[tex]\sigma[/tex] represent the population standard deviation (variable of interest)
[tex]\sigma_o =0.2[/tex] represent the value that we want to test
n represent the sample size
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Based on this the system of hypothesis should be:
Null Hypothesis: [tex]\sigma=0.2[/tex]
Alternative hypothesis: [tex]\sigma \neq 0.2[/tex] (Changes on the deviation)
In order to test these system of hypothesis we need to select a significance level [tex]\alpha[/tex], then we need to calculate an statistic given by this formula.
[tex]\chi^2 =\frac{(n-1)s^2}{\sigma^2_o}[/tex]
Then we need to calculate the degrees of freedom for the statistic on this case
[tex]df=n-1[/tex]
And after this we need to calculate the pvalue based on the significance, the alternative hypothesis and the statistic calculated.
If the [tex]p_v <\alpha[/tex] we reject the null hypothesis
If the [tex]p_v >\alpha[/tex] we FAIL reject the null hypothesis
Consider the following problem: A farmer with 850 ft of fencing wants to enclose a rectangular area and then divide it into four pens with fencing parallel to one side of the rectangle. What is the largest possible total area of the four pens?
Answer:
18,062.5 square feet
Step-by-step explanation:
The largest area will be obtained when half the fence is used in each of the orthogonal directions. That is, the pen will have two parallel sides that total 425 feet, and 5 parallel sides and partitions that total 425 feet.
The long sides are 212.5 feet, and the short sides are 85 feet, so the overall area is ...
(212.5 ft)(85 ft) = 18,062.5 ft²
__
Working Out
Suppose the long side is length x. Then the lengths of the 2 ends and 3 dividers are ...
short side = (850 -2x)/5
Then the overall area is the product of long side and short side:
A = x(850 -2x)/5 = (2/5)(x)(425 -x)
This equation is that of a parabola that opens downward. Its vertex (maximum) is at the value of x halfway between the zeros of 0 and 425. That is, area is a maximum when x=212.5.
That maximum area is ...
A = (2/5)(212.5)(425 -212.5) = 18,062.5 . . . square feet

A rectangular parking lot has a perimeter of 384 meters. The length of the parking lot is 36 meters less than the width. Find the length and the width.
Answer:
The length and width of the parking lot is 78 meters and 114 meters respectively.
Step-by-step explanation:
Given;
Perimeter of the parking lot = [tex]384\ m[/tex]
Solution,
Let the width of the parking lot be x.
Then, according to question length = (x-36).
The perimeter of a rectangle is sum of all the sides of rectangle. Which is given by an expression;
[tex]perimeter=2\times(length+width)[/tex]
Now substituting the values, we get;
[tex]384=2\times(x-36+x)\\\frac{384}{2}=(2x-36)\\192=2x-36\\192+36=2x\\2x=228\\x=\frac{228}{2}= 114[/tex]
Width = [tex]114\ m[/tex]
Length = [tex]x-36=114-36=78\ m[/tex]
Hence the length and width of the parking lot is 78 meters and 114 meters respectively.

Miguel took a taxi to the beach 23 miles from his hotel. After his day at the beach, he took a bus back for 11 miles. Then a friend pick him up and drove another 12 miles towards the hotel. How many more miles does Magill need to go until he is back at his hotel
Answer:
0 additional miles
Step-by-step explanation:
Miguel travelled from his hotel to the beach by taxi. Total distance travelled by Miguel during the journey is 23 miles.
During the return journey, he travelled by a bus for 11 miles to an intermediate location.
From this point his friend picked him up and drove him towards the hotel for 12 miles.
So the total distance travelled by Miguel during the return journey = 11 + 12 = 23 miles
But this is the same distance as the onward journey. So at the end, Miguel is back at the hotel and there are 0 additional miles that he needs to cover.
Answer: 0 miles
Step-by-step explanation:
Miguel took a taxi to the beach 23 miles from his hotel. After his day at the beach, he took a bus back for 11 miles. This means at this point, his distance from his hotel is 23 - 11 = 12 miles. Then a friend pick him up and drove another 12 miles towards the hotel. This means that they covered the remaining 12 miles from the hotel. Therefore
Miguel needs to go 12 - 12 = 0 miles until he is back at his hotel.
The late fee for library books is $2.00 plus 15 cents each day for a book that is late.If Maria's fee for a late book was $3.20,write and solve a linear equation to find many days late the book was.
First we will subtract $2 from $3.2 since that is late fee to get $1.2.
Now we divide $1.2 by $0.15 to get number of cents hence 8 days.
The answer is Maria is 8 days too late to hand over the book.
Hope this helps.
The linear equation is 3.20 = 2.00 + 0.15*x. Hence, Maria's book was 8 days late.
To find out how many days Maria's book was late, we need to set up a linear equation using the given information.
The total late fee equation is given by:
Late Fee = 2.00 + 0.15*x
Where $2.00 is the base fee, and 0.15 dollars is the additional late fee per day. Since Maria's total fee was $3.20, we can set up the equation as follows:
3.20 = 2.00 + 0.15*x
Now, solve for x, which represents the number of days the book was late:
Subtract $2.00 from both sides:
3.20 - 2.00 = 0.15*x
Simplify the equation:
1.20 = 0.15*x
Divide both sides by 0.15 to isolate x:
x = 1.20 / 0.15
Calculate the result:
x = 8
So, Maria's book was 8 days late.
Tim is looking at two websites that allow customers to print their own designs on T-shirts. One website charges $24 per T-shirt plus $8 shipping. The other website uses the equation C = 22 n + 12 C=22n+12 to find the total cost, C C, of printing on T-shirts. What is the difference in the cost of each website if Tim orders 10 T-shirts?
Answer: The difference is $16
Step-by-step explanation:
n will equal the amount of t-shirts bought
Website 1's Costs: c = 24n + 8
Website 2's cost: c = 22n + 12
Then, we substitute 10 for n
c = 24(10) + 8
c = 240 + 8
c = 248
c = 22(10) + 12
c = 220 + 12
c = 232
248 - 232 = 16
The difference between the total cost of the first website and that of the second based on the given function will be $16.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
As per the given,
On the first website,
Cost to buy 10 T-shirts.
C = 24(10) + 8
C = 240 + 8
C = $248
The second website
The total cost to buy 10 T-shirts
C = 22(10) + 12
C= 220 + 12
C= $232
The differnce $248 - $232 = $16
Hence "The difference between the total cost of the first website and that of the second based on the given function will be $16".

The monthly output P of a light bulb factory is given by the formula P = 450LK, where L is the amount invested in labor and K the amount invested in equipment (in thousands of dollars). If the company needs to produce 4,000 units per month, how should the investment be divided among labor and equipment to minimize the cost of production? The cost of production is L + K. (Round your answers to the nearest cent.)investment in labor _______ $investment in equipment ________$
Answer:
C(p) = 4,96 (in thousands of dollars)
l = 2980 $ invest in labor
k = 2980 $ invest in equipment
Step-by-step explanation:
Information we have:
Monthly output P = 450*l*k ⇒ k = P/450*l
But the production need to be 4000
Then k = 4000/450*l
Cost of production = l * k (in thousands of dollars)
C(l) = l + 4000/450*l
Taking derivatives (both members of the equation)
C´(l) = 1 - 400 /45*l² ⇒ C´(l) = 0 ⇒ 1 - 400/45l² = 0
45*l² - 400 = 0 ⇒ l² = 400/45
l = 2.98 (in thousands of dollars)
l = 2980 $ And
k = 400/45*l ⇒ k 400/45*2.98
k = 2.98 (in thousands of dollars)
C(p) = l + k
C(p) = 2980 + 2980
C(p) = 5960 $
