Benjamin went shopping for a new phone
because of a sale. The price on the tag was
$28, but Benjamin paid $15. 40 before tax.
Find the percent discount
The percent discount on the phone because of a sale is 45%.
To find the percent discount, we need to calculate the difference between the original price and the discounted price, and then express that difference as a percentage of the original price.
First, let's find the difference between the two prices: $28 - $15.40 = $12.60. This means that Benjamin saved $12.60 on the phone.
Now, let's find the percent discount. We can do this by dividing the savings by the original price, and then multiplying the result by 100: ($12.60 / $28) * 100 = 45%.
So, Benjamin received a 45% discount on the phone before tax. This calculation shows that the sale allowed him to save a significant amount on his purchase. It's important to compare original and discounted prices to determine if a sale provides good value.

1. at american high school, 35% of the students are freshmen. one-fourth of the students
are sophomores. nine-fortieths of the students are juniors. and there are 308 seniors.
how many students are freshmen?
There are 616 freshmen in the school according to fraction, percentage and number of different types of student.
Let us represent the total number of students in school as x. So, the equation that will form is -
Number of freshmen + sophomores + juniors + seniors = total number of students
35x/100 + x/4 + 9x/40 + 308 = x
Adding the values and converting into decimal.
0.825x + 308 = x
Rewrite the equation
308 = (1 - 0.825)x
308 = 0.175x
x = 308/0.175
Divide the values
x = 1760
So, number of freshmen = 0.35 × 1760
Multiply the numbers
Number of freshmen = 616
Thus, there are 616 freshmen.

You deposit $2,500 in an investment
account. The rate of growth is 4. 55% a year.
If you make no further deposits or
withdrawals, and the investment is allowed
to grow uninhibited, how long will it take for
your investment to reach $5,000? Round to
the nearest tenth.
It will take approximately 15.27 years for your investment to reach $5,000 at a growth rate of 4.55% per year.
Using the compound interest calculation, we can determine how long it will take for your investment to grow to $5,000 at a growth rate of 4.55% per year:
[tex]A = P(\frac{1 + r}{n} )^(^n^t^)[/tex]
Where:
A = the final amount ($5,000)
P = the initial deposit ($2,500)
r = the interest rate (4.55%)
n = the number of times interest is compounded per year (assuming yearly compounding, n=1)
t = the number of years
Plugging in the values, we get:
[tex]\$5,000 = \$2,500(\frac{1 + 0.0455}{1} )^(^1^t^)[/tex]
Simplifying, we get:
[tex]2 = (1.0455)^t[/tex]
Taking the natural logarithm of both sides, we get:
ln(2) = t ln(1.0455)
Solving for t, we get:
t = ln(2) / ln(1.0455) = 15.27 years
Therefore, it will take approximately 15.27 years for your investment to reach $5,000 at a growth rate of 4.55% per year.

You have a 35-mile commute into work. Since you leave very early, the trip going to work is easier than the trip home. You can travel to work in the same time that it takes for you to make it 28 miles on the trip back home. Your average speed coming home is 10 miles per hour slower than your average speed going to work. What is your average speed going to work?
Average speed going to work is 50 mph.
What is average speed to work?Let's assume that the average speed going to work is "x" miles per hour.
Since you can travel to work in the same time it takes for you to make it 28 miles on the trip back home, we can set up an equation using the formula:
time = distance / speed
The time it takes to travel 35 miles to work is:
time to work = 35 / x
The time it takes to travel 28 miles on the return trip is:
time to return = 28 / (x - 10)
We know that both times are equal, so we can set them equal to each other and solve for "x":
[tex]35 / x = 28 / (x - 10)[/tex]
Multiplying both sides by x(x - 10), we get:
[tex]35(x - 10) = 28x[/tex]
Expanding the left side and simplifying, we get:
[tex]35x - 350 = 28x[/tex]
[tex]7x = 35[/tex]
[tex]x = 50[/tex]
Therefore, your average speed going to work is 50 miles per hour.
To solve this problem, we used the formula for speed, distance, and time. We t up an equation using the fact that the time it takes to travel to work is equal to the time it takes to travel 28 miles on the return trip. We then solved for the average speed going to work by setting the two times equal to each other and solving for "x". Finally, we found that the average speed going to work is 50 miles per hour.

A student is buying a shirt that has a regular price of $18. After using a coupon, the price of the shirt is 0. 75x, where x is the regular price of the shirt. The clerk includes 6% sales tax on the price of the shirt. How much change should the student receive if the student pays for the shirt using a $20 bill?
The student should receive $5.69 in change.
How to find the price?The price of the shirt after the coupon is applied is 0.75 times the regular price, so:
Price of the shirt = 0.75x
If x = $18, then the price of the shirt is:
Price of the shirt = 0.75($18) = $13.50
The clerk adds 6% sales tax to the price of the shirt:
Sales tax = 6% of $13.50 = 0.06($13.50) = $0.81
So the total cost of the shirt is:
Total cost = $13.50 + $0.81 = $14.31
If the student pays with a $20 bill, the change the student should receive is:
Change = $20 - $14.31 = $5.69

Answer:
(x-6)²+(y+3)²=17²
Step-by-step explanation:
The equation of a circle with center (a,b) and radius r is given by the formula:
(x - a)² + (y - b)² = r²
In this case, the center of the circle is (6,-3), and it passes through the point (-9,5). To find the radius of the circle, we need to calculate the distance between the center and the point on the circle. Using the distance formula, we get:
r = √[(x₂ - x₁)² + (y₂ - y₁)²]
= √[(-9 - 6)² + (5 - (-3))²]
= √[225 + 64]
= √289
= 17
So, the radius of the circle is 17. Now we can plug in the values for the center and radius into the equation of a circle:
(x - 6)² + (y + 3)² = 17²

(b) Calculate the surface area of the pyramid if a 10 and b = 12.
(c) If L=192 and a=b, find the value of a
Answer:
Step-by-step explanation:
(a) The total payment for a student who registers for m language subjects and n other subjects can be expressed as:
Total payment = Administrative fee + Tuition fee for language subjects + Tuition fee for other subjects
Total payment = RM30 + RM45m + RM40n
Total payment = RM30 + 45m + 40n
(b) For Zaleha who registers for 3 language subjects and 2 other subjects, the total payment can be calculated as:
Total payment = RM30 + (3 x RM45) + (2 x RM40)
Total payment = RM30 + RM135 + RM80
Total payment = RM245
(c) Chan pays RM280 when she registers for 2 language subjects and p other subjects. We can use the formula derived in part (a) to find the value of p:
Total payment = RM30 + (2 x RM45) + (p x RM40)
RM280 = RM30 + RM90 + RM40p
RM280 - RM120 = RM40p
RM160 = RM40p
p = 4
Therefore, Chan registers for 2 language subjects and 4 other subjects.
(a) The surface area of a right pyramid with a square base can be calculated as:
L = base area + 1/2 x perimeter of base x slant height
The base of the pyramid is a square, so its area can be expressed as:
Base area = a^2
The perimeter of the base can be calculated as:
Perimeter of base = 4a
The slant height can be calculated using the Pythagorean theorem:
slant height = sqrt(h^2 + (a/2)^2)
where h is the height of the pyramid.
Substituting these values in the surface area formula, we get:
L = a^2 + 1/2 x 4a x sqrt(h^2 + (a/2)^2)
L = a^2 + 2a x sqrt(h^2 + (a/2)^2)
(b) If a = 10 and b = 12, then the surface area of the pyramid can be calculated as:
L = 10^2 + 2 x 10 x sqrt(h^2 + (10/2)^2)
L = 100 + 20sqrt(h^2 + 25)
Given that L = 192, we can solve for h:
192 - 100 = 20sqrt(h^2 + 25)
92 = 20sqrt(h^2 + 25)
4.6 = sqrt(h^2 + 25)
4.6^2 - 25 = h^2
h^2 = 2.76
h = sqrt(2.76)
h ≈ 1.66
Substituting these values in the surface area formula, we get:
L = 10^2 + 2 x 10 x sqrt(1.66^2 + (10/2)^2)
L ≈ 314.9
Therefore, the surface area of the pyramid is approximately 314.9 square units.
(c) If L = 192 and a = b, then the surface area formula can be simplified as:
L = a^2 + 2a x sqrt(h^2 + (a/2)^2)
192 = a^2 + 2a x sqrt(h^2 + (a/2)^2)
We also know that the height of the pyramid is equal to the side length of the triangular faces. Since the pyramid is a right pyramid, the height and slant height are related by the Pythagorean theorem:
h^2 + (a/2)^
Craig needs to measure 2 3/8 cups. How many times must he fill a 1/3 cup measuring cup?
First, we need to convert the mixed number 2 3/8 to an improper fraction:
2 3/8 = (2 x 8 + 3) / 8 = 19/8
To find out how many times Craig needs to fill a 1/3 cup measuring cup, we can divide 19/8 by 1/3:
(19/8) / (1/3) = (19/8) x (3/1) = 57/8
Therefore, Craig needs to fill a 1/3 cup measuring cup 57/8 times to measure 2 3/8 cups.
