The total cost of purchase on 2 pants and 1 shirt is $76.986.
Given that, you bought 2 pairs of pants at $28.99 each, and one shirt at $21.34.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Now,
The cost of 2 pairs of pants
= 2 ×28.99
= $57.98
Total cost of two pants and a shirt
= 21.34+51.98
= $73.32
Tax =5% of 73.32
= 5/100 ×73.32
= 0.05 ×73.32
= $3.666
Total cost of purchase =73.32+3.666
= $76.986
Therefore, the total cost of purchase on 2 pants and 1 shirt is $76.986.

Find the dimensions of a rectangle whose width is 6 miles less than its length and whose area is 55 square miles.
At 7 a.m. Gene left Austin and headed south at 10 miles per hour. At 8 a.m. Anne left from the same place and headed south on the same road. If Anne was 60 miles ahead by 3 p.m. on the same day, what was her speed?
Anne's speed is 20 miles per hour. If she returned home by the same path 7 hours and 30 minutes after she left, her average speed for the entire trip is 18.67 miles per hour while her average velocity is zero.
To answer this question, we need to calculate Anne's speed based on the information given. Gene started at 7 a.m. traveling at 10 miles per hour. By the time Anne starts at 8 a.m., Gene has already covered 10 miles (since he travels for 1 hour). The time from 8 a.m. to 3 p.m. is 7 hours. Both Anne and Gene travel the same path for these 7 hours, but Anne is 60 miles ahead of Gene by 3 p.m. Therefore, we need to calculate the total distance Gene traveled in 8 hours, add 60 miles to that distance, and then divide by 7 to find Anne's speed.
First, we determine Gene's total travel distance by 3 p.m., which is 10 miles/hour * 8 hours = 80 miles. Anne is 60 miles ahead, meaning she traveled 80 miles + 60 miles = 140 miles in 7 hours. Thus, Anne's speed is 140 miles \/ 7 hours = 20 miles per hour.
For part (c), if Anne returned home by the same path 7 hours and 30 minutes after she left, the total trip time would be 15 hours (7 hours to 3 p.m. and another 7 hours and 30 minutes back). Since the round trip distance is 140 miles out and 140 miles back, the total distance is 280 miles. Her average speed is total distance divided by total time, hence 280 miles / 15 hours = 18.67 miles per hour. The average velocity for the round trip is zero because she ends up at the starting point, so the overall displacement is zero.

The square of a positive number decreased by twice the number is 48. Find the number
Let the required positive number is x.
The square of the number is [tex]x^2[/tex]
Now, we have been given that square of a positive number decreased by twice the number. It means we have
[tex]x^2-2x[/tex]
Now, it is equal to 48. Hence, we have
[tex]x^2-2x=48\\ x^2-2x-48=0\\ x^2-8x+6x-48=0\\ x(x-8)+6(x-8)\\ (x-8)(x+6)=0\\ x=8,-6[/tex]
The number is positive, Hence, we have [tex]x=8[/tex]

For Jack's birthday, his mom is taking him and 12 friends to the zoo. If she pays $11 for each ticket using her credit card, what impact will it have on the available credit left on her credit card?
The impact on Jack's mom's available credit after purchasing zoo tickets for Jack and 12 friends at $11 each will be a reduction of $143.
When Jack's mom pays $11 for each zoo ticket for him and his 12 friends, she will be purchasing a total of 13 tickets (one for Jack plus 12 for his friends). To calculate the total cost, multiply the number of tickets by the price per ticket:
Number of tickets: 13 (Jack + 12 friends)Price per ticket: $11Total cost: 13 tickets × $11 per ticket = $143The total impact on her credit card's available credit will be a reduction of $143. If she had some available credit limit before this purchase, we just subtract this amount from her available credit to determine the new available credit.
What is the total amount and the amount of interest earned on $6,500 at 6% for 25 years?
Answer:
Total amount earned after 25 years=$27,897.16
Step-by-step explanation:
Step 1: Express formula for calculating total amount
The total amount after 25 years can be expressed as;
A=P(1+r)^n
where;
A=total amount after 25 years
P=principal amount
r=annual interest rate
n=number of years
Step 2: Substitute values in the expression
In our case;
P=$6,500
r=6%=6/100=0.06
n=25 years
replacing in the original expression;
A=6,500(1+0.06)^25
A=27,897.16
Total amount earned after 25 years=$27,897.16
Final answer:
The total amount after 25 years will be $27,897.16, and the amount of interest earned on a $6,500 investment at a 6% annual interest rate will be $21,397.16.
Explanation:
To calculate the total amount and interest earned on $6,500 at 6% for 25 years, we'll assume that the interest is compounded annually. The formula to calculate the total amount with compound interest is:
A = P(1 + r/n)^(nt)
Where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (in decimal).n is the number of times that interest is compounded per year.t is the time the money is invested or borrowed for, in years.Let's plug the values into the formula:
A = $6,500(1 + 0.06/1)^(1*25)
A = $6,500(1 + 0.06)^25
A = $6,500(1.06)^25
A = $6,500 * 4.29187072
A = $27,897.16
The total amount after 25 years will be $27,897.16.
To find the interest earned, subtract the principal from the total amount:
Interest = A - P
Interest = $27,897.16 - $6,500
Interest = $21,397.16
The amount of interest earned will be $21,397.16.

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 222 inches and a height of 666 inches. It is a challenge to fill the narrow cones with their long fries. They want to use new cones that have the same volume as their existing cones but a larger radius of 444 inches. What will the height of the new cones be?
To find the height of the new cone with a larger radius that maintains the same volume, we calculate the volume of the original cone and solve for the new height using the cone volume formula.
Explanation:The student wants to find out the new height of the cone with a larger radius while maintaining the same volume as the original cone. The volume of a cone is given by the formula V = 1/3 πr²h. To find the height of the new cone, we'll use the volume of the original cone as the constant value.
Let's first calculate the volume of the original cone:
V_original = 1/3 π(222²)(666)Now, let's set up an equation with the new radius to solve for the new height (h_new):
1/3 π(444²)(h_new) = V_originalh_new = (V_original) / (1/3 π(444²))By substituting the V_original from step 1 into step 3, we can solve for h_new. The result will be the height of the new cone with a radius of 444 inches that has the same volume as the original cone.
The perimeter of a rectangular floor is 50 feet. find the dimensions of the floor if the length is four times the width.
The dimensions of the rectangle are width = 5 feet and length = 20 feet.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the length and width.
The perimeter of a rectangle = 2(L + W)
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that the perimeter of a rectangular floor is 50 feet.
The length is four times the width.
Let the width of the rectangle is x
So the length of the rectangle = 4x
The perimeter of a rectangle = 2(L + W)
50 = 2(4x + x)
50 = 2(5x)
50 = 10x
10x = 50
x = 50 /10
Apply the division operation,
x = 5
So the length of the rectangle = 4(5) = 20 feet
Therefore, the dimensions of the rectangle are width = 5 feet and length = 20 feet.

Find the distance between the two points. (2, 5) and (–1, –5)
each of the circles below has an area of 196 pi square units find the perimeter of the rectangle
Answer:
Step-by-step explanation:
Alright lets get started.
We have given the area of each circle as 196 pi square units.
since the area of the circle =[tex]\pi*radius^2[/tex]
so,the radius of the circle :
[tex]196\pi =\pi r^2[/tex]
[tex]r^2=196[/tex]
[tex]r=14[/tex]
therefore the diameter of the circle will be [tex]2*radius=2*14=28[/tex]
the perimeter of the rectangle=[tex]2*(length+ width)[/tex]
the length of the rectangle will be addition of diameters of the circle=[tex]28+28=56[/tex]
breadth of the rectangle is equal of the diameter =28
Perimeter of the rectangle =[tex]2*(56+28)=168[/tex]
Answer 168 units.
The perimeter of the given rectangle is 168 units
Given that area of each of the circles are [tex] 196 \pi [/tex] sq units and we know that the area of circle [tex]=\pi r^{2}[/tex] using this radius of the circle will be
[tex]\pi r^{2} =196\pi\\ r^{2} = 196\\ \\ r=14[/tex]
So, the diameter of the circle is twice the radius which is
[tex]2\times r\\ 2\times 14 =28 [/tex]
Here we can see that length of rectangle is equal to twice the diameter of the circle and breadth is equals to twice the radius
[tex]length= 28+28=56[/tex]
[tex]breadth = 2\cdot14=28[/tex]
How to find the perimeter of the given rectangle ?
To find the perimeter we use the formula
Perimeter of rectangle = [tex]2\cdot(length + breadth)[/tex]
On solving we get ,
[tex]2\cdot(56 +28)\\ 168 units[/tex]
Therefore, The perimeter of the given rectangle is 168 units
