Susan makes a purchase of $175 and is charged 7.75% for sales tax. What is the total cost of the purchase if Susan charges it on a credit card with a daily interest rate of 0.039% and pays the balance off at the end of 30 days? a. $176.17 b. $186.70 c. $190.77 d. $200.26
Answer:
C. 190.77
Step-by-step explanation: edge 2022
The required, total cost of the purchase is $190.77. Option C is correct.
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here,
To calculate the total cost of the purchase, we first need to calculate the amount of sales tax and add it to the original price.
Sales tax = 7.75% of $175 = 0.0775 x $175 = $13.56
Total cost of purchase = $175 + $13.56 = $188.56
If Susan charges the purchase to her credit card and pays it off after 30 days, she will be charged interest on the outstanding balance for those 30 days. The interest rate is 0.039% per day, which is equivalent to 1.17% per month (0.039% x 30).
The interest charged on the outstanding balance after 30 days will be:
Interest = $188.56 x 1.17% = $2.20
Therefore, the total cost of the purchase, including sales tax and credit card interest, will be,
Total cost = $188.56 + $2.20 = $190.76
Therefore, the total cost of the purchase is $190.77.

Find the 12th term of the geometric sequence 2, 10,50,...
The first term of the geometric sequence is 2 and the common ratio is 5. So, the 12th term of the geometric sequence is 97656250.
Geometric sequence:Important information:
Given geometric sequence is 2, 10,50,...We need to find the 12 th term.
In the given geometric sequence, the first term is [tex]a=2[/tex] and the common ratio is [tex]d=\dfrac{10}{2}=5[/tex].
The nth term is:
[tex]a_n=ar^{n-1}[/tex]
Where [tex]a[/tex] is first term, [tex]r[/tex] is common ratio.
The 12th term is:
[tex]a_{12}=2(5)^{12-1}[/tex]
[tex]a_{12}=2(5)^{11}[/tex]
[tex]a_{12}=97656250[/tex]
Therefore, the 12th term of the geometric sequence is 97656250.

Michael spends a half hour adding water to his pool part of the time at a rate of 15 gallons per minute and the rest of the time at a rate of 9 gallons per minute. Let t be the time in minutes that he adds water at the faster rate write an algebraic expression to represent the total number of water added to the pool
Answer:
24t + 270 gallons
Step-by-step explanation:
Given that :
Addition rate 1 = 15 gallons per minute
Addition rate 2 = 9 gallons per minute
Total time spent adding water = half an hour = 30 minutes = 0.5 hour
Time spent adding water at faster rate = t
Time spent addition water at slower rate = (30 - t)
Total number of water added to the pool :
Amount of water added = addition rate * time
Hence,
Amount of water added at faster rate :
(15 gal / min) * t = 15t gallons
Amount added at slower rate :
(9 gal / min) * (30 - t) = (270 - 9t) gallons
Total amount of water added to the pool:
15t gallons + (270 - 9t)gallons
15t + 270 + 9t
24t + 270 gallons

Cus angles of a triangle add to 180 and so the inside angle is 130 and they are vertical angles so they are the same right? right?
Step-by-step explanation:
Answer:
130 degrees
Step-by-step explanation:
I first came up with the equation 30+20+?=180 (I got 180 because every angle in a triangle added up is 180), then added the 30 and 20 to get 50+?=180. I subtracted 50 from both sides and got ?=130. I know that the angle on the inside and the outside are equal because it seems like a reflection, so if the inside angle is 130 the outside angle is 130 degrees too.

Rectangle A measures 10 inches by 8 inches. Rectangle B is an enlarged copy of Rectangle A. Select all of the measurement pairs that could be the dimensions of Rectangle B.
Answer:
See Explanation
Step-by-step explanation:
Given
Rectangle A:
[tex]Length: 10\ in[/tex]
[tex]Width: 8\ in[/tex]
Required
Determine the possible dimensions of Rectangle B
The question has missing options; however, the question can still be solved.
Rectangle B being an enlarged copy of A implies that the dimension of A A is enlarged in equal proportion to form B
Take for instance, the measurements of Rectangle B are
[tex]Length: 15 in[/tex]
[tex]Width: 12 in[/tex]
Divide the corresponding lengths of B by A to get the enlargement ratio
[tex]Ratio = \frac{B}{A}[/tex]
For length:
[tex]Ratio = \frac{15}{10}[/tex]
[tex]Ratio = 1.5[/tex]
For width
[tex]Ratio = \frac{12}{8}[/tex]
[tex]Ratio = 1.5[/tex]
Notice that both ratios are the same.
For this measurement of B, we can conclude that B is an enlargement of A
Assume another measurements for B
[tex]Length: 20\ in[/tex]
[tex]Width: 10\ in[/tex]
Calculate Ratios
[tex]Ratio = \frac{B}{A}[/tex]
For length:
[tex]Ratio = \frac{20}{10}[/tex]
[tex]Ratio = 2[/tex]
For width
[tex]Ratio = \frac{10}{8}[/tex]
[tex]Ratio = 1.25[/tex]
Notice that, both ratios are not equal.
For this measurement of B, we can conclude that B is not an enlargement of A
Conclusively, all you have to do is: determine the ratios of the dimensions of B to A, if the result are equal then B is an enlarged copy of A; if otherwise, then B is not an enlarged copy

A softball team is ordering pizza to after the tournament they plan to order a cheese pizza(c) that cost eight dollars each and pepperoni pizza(P) cost $12 each gotten from the odyssey pizzas.
Which expression represents the total cost of all of the pizzas they order?
Answer:
t = 8c + 12P
Step-by-step explanation:
We are told that cheese pizza(c) costs eight dollars.
This means for c number of cheese pizzas, cost is $8c
Also, we are told that cost of pepperoni pizza is $12 each.
So, for P number of pepperoni pizzas, the cost is $12P
Therefore expression of total cost(t) will be the sum of the cost of c number of cheese pizzas and P number of pepperoni pizzas.
Thus;
t = 8c + 12P

b.

C.
-3.8x = -7.4
4(x - 1) – 3(x - 2) = -8
d.
x=2 is a solution of equations -2(x – 4) = 4 and 26/x=13
What is Equation?Two or more expressions with an Equal sign is called as Equation.
-2(x-4)=4
-2(2-4)=4
4=4
Hence, x=2 is the solution
26/x=13
Now x=2
26/2=13
13=13
Hence, x=2 is the solution
-3.8x=-7.4
Now x=2
-3.8×2=-7.4
-7.6=-7.4
x=2 is not a solution of -3.8×2=-7.4
4(x - 1) – 3(x - 2) = -8
4(2-1)-3(2-2)=-8
4=-8
x=2 is not a solution of -3.8×2=-7.4
Hence, x=2 is a solution of equations -2(x – 4) = 4 and 26/x=13
