sarosh receives 8% commission on the final price of the clothing he sells . a customer bought a $45.00 coat the was marked 20% off and a $95.00 suit that was marked 30% off what would sarosh's commission be on that customers purchase?
Answer:
$8.2
Step-by-step explanation:
The final price of the coat = $45 -0.2 * $45 = $36
The final price of the suit = $95 − 0.3 * $95 = $66.5
sarosh's commission = 0.08 * ( $36 + $66 ) = $8.2

Find the simple interest and the total amount after three years. Principal =11,750= 11 =11,750 rupees Annual rate of interest 7.5%= Total interest == = rupees Total amount = = = rupeesFind the simple interest and the total amount after three years. Principal =11,750= 11{,}750 =11,750 rupees Annual rate of interest=7.5%=Total interest rupees Total amount rupees
The simple interest after three years is ₹2625 and the total amount is ₹14,375.
Explanation:To find the simple interest and total amount after three years, we can use the formula:
Simple Interest = Principal × Rate × Time
Total Amount = Principal + Simple Interest
Given that the Principal is ₹11,750 and the Annual Rate of Interest is 7.5%, we can calculate the Simple Interest by substituting these values into the formula:
Simple Interest = ₹11,750 × 0.075 × 3
After calculating, we find that the Simple Interest is ₹2625.
To find the Total Amount, we can use the formula:
Total Amount = Principal + Simple Interest
Substituting the values into the formula, we get:
Total Amount = ₹11,750 + ₹2625
After calculation, the Total Amount is ₹14,375.
Consider the sequence 130, 143, 156, 169, ... Write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.
Answer:
a(n) = 130 + (n-1) 13
13th term = 286
Step-by-step explanation:
We are given a sequence of numbers: 130, 143, 156, 169, ... and we are to write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.
We know that the arithmetic sequence can be defined by:
[tex]a_n=d(n-1)+c[/tex]
where [tex]d[/tex] = the common difference between consecutive terms ; and
[tex]c[/tex]=[tex]a_1[/tex]
13th term:
[tex]a_{13}=130+(12)13 = 286[/tex]
Therefore, the formula for this sequence will be a(n) = 130 + (n-1) 13 and 13th term is 286.

YES
Step-by-step explanation:
First, let's find the total number of seats int he airplane.
14 + 64 + 4 * 108 = 510
The airplane has a total or 510 seats.
Half of the number of seats is 510/2 = 255.
Now let's calculate the number of seats being used and compare with 255.
5/7 * 14 + 5/16 * 64 + 5/9 * 4 * 108 =
= 2 * 5 + 4 * 5 + 12 * 4 * 5
= 10 + 20 + 240
= 270
270 seats are being used.
270 is greater than 255, so more than half of the seats are being used.

The variable y is directly proportional to the variable x. If y = 12 when x = 14, what is the value of x when y = 24? A) 26 B) 28 C) 30 D) 32
CORRECT ANSWERS ONLY, ILL MARK YOU THE BRAINLIEST!!!!!!!!!
Hi There!
Answer:
B) 28
Step-by-step explanation:
y = 12 and x = 14 are both proportional.
y = 24 and x = ? are both proportional.
You notice that 24 is twice as much as 12 so we do the same with x.
14 * 2 = 28
They are both proportional when y = 24 and x = 28.
Hope This Helps :)
Answer:
B) 28
Step-by-step explanation:
The equation for direct proportion is
y= kx
If y =12 and x =14
12 = k * 14
Divide each side by 14
12/14 = k
Simplifying
6/7 =k
y =6/7 x
Now if y =24
24 = 6/7 x
Multiply each side by 7/6 to isolate x
24 * 7/6 = 7/6 * 6/7 x
28 =x

Which algebraic expression repesents the phrase? Cindy studied seven more hours than Nikki studied. a. n+7 b. 7-n c. 7n d. n/7
Answer:
Option a is the correct choice.
Step-by-step explanation:
Let n be number of hours studied by Nikki.
We are told that Cindy studied seven more hours than Nikki studied. This means that number of hours studied by Nikki plus 7 hours equals to the number of hours studied by Cindy.
We can represent this information in an expression as :
[tex]\text{The number of hours studied by Cindy}=n+7[/tex]
We can see from our given choices that expression given in option a represents the number of hours studied by Cindy in terms of hours studied by Nikki.
Therefore, option a is the correct choice.
What value of $k$ will make $4x^2 - 20x + k$ the square of a binomial?
Answer:
k = 25
Step-by-step explanation:
(2x - sqrt(k) )^2 Expand this as a binomial
4x^2 - 4x*sqrt(k) + k The middle term must be -20x Solve for k so it is
-4xsqrt(k) = - 20x Divide by -4x
sqrt(k) = -20x/-4x Do the division
sqrt(k) = 5 Square both sides
k = 25
jim and Jon are painting a fence. Jon painted 1/4 of the fence. Jim painted 5/12 of the fence. how much of the fence did they paint in total?
Our first step is the find the lcm of 4 and 12 so we can add the two fractions without having a problem.
The lcm of 4 and 12 is clearly 12 because 12 is a multiple of 4. 12 divided by 4 is 3, so you must multiply by 3/3 to be able to add the two fractions.
1/4*(3/3)=3/12.
So, 3/12+5/12=7/12.
Jim and Jon painted 7/12 of the the fence.
Answer:
2/3 of the fence
Step-by-step explanation:
Jim painted 1/4 of the fence
Jon painted 5/12 of the fence
Together they painted
1/4+5/12 of the fence
We need a common denominator to add the fractions
The common denominator is 12
1/4*3/3 + 5/12
3/12 + 5/12
8/12
This can be simplified by dividing the top and bottom by 4
2/3
Together, they painted 2/3 of the fence.
One number is 7 more than another.The difference between their squares is 217.What are the numbers?
The problem where one number is 7 more than another and their squares differ by 217 can be solved by creating a system of equations and simplifying to find the numbers are 12 and 19.
Explanation:To solve the problem where one number is 7 more than another and the difference between their squares is 217, we can create a system of equations. Let's assume the first number is x and the second number is x+7. The problem then translates to the equation (x+7)² - x² = 217.
Step-by-step solution:
Expand the left side of the equation: (x+7)² - x² = (x² + 14x + 49) - x².Cancel out the x² terms: 14x + 49 = 217.Subtract 49 from both sides: 14x = 168.Divide both sides by 14: x = 12.Therefore, the first number is 12 and the second number is 12 + 7 = 19.After computing the solution, we find that the two numbers are 12 and 19.
The radius of the circle shown below is 7 inches what is the approximate length of AB?
Answer:
16.5 inches
Step-by-step explanation:
WE have arc length formula for a circle as
Arc length = [tex]\frac{x}{360} (2\pi r)[/tex]
where x is the central angle the arc subtends at the centre.
Here x = 135
r= 7 inches
Hence arc length
=[tex]\frac{135}{360} (2\pi )(7) =16.5"[/tex]
Hence option B
16.5 inches is right answer for arc length for a circle of radius 7 inches.
The measure of length of arc AB is 16.5 inches. Therefore, option B is the correct answer.
What is the relationship between a central angle and its arc?An arc of a circle is a section of the circumference of the circle between two radii. A central angle of a circle is an angle between two radii with the vertex at the centre. The central angle of an arc is the central angle subtended by the arc. The measure of an arc is the measure of its central angle.
Given that, the radius of the circle is 7 inches and measure of arc AB is 135°.
Let O be the center of circle.
So, ∠AOB=135°
We know that, arc length of circle is θ/360° ×2πr
= 135°/360° ×2×3.14×7
= 0.375×2×3.14×7
= 16.485
≈ 16.5 inches
Therefore, the approximate length of AB is 16.5 inches.

plz help Pru, Piper, and Phoebe share spices in the ratio 5:3:4. If Pru has 24 more spices than Piper, how many spices does Phoebe have?
Answer:
Step-by-step explanation: Pru, Piper, Phoebe their ratio 5:3:4 added = 12
What this would mean is that Pru has 5/12 of the total amount, Piper has 3/12 of the total, and Phoebe has 4/12 of the total amount of spices all together.
pru = piper + 24
5/12x = 3/12x + 24
5/12x - 3/12x = 24
2/12x = 24
x = 24 / (1/6)
x = 24 * 6
x = 144 spices in all.
Pru has : 5/12(144) = 720/12 = 60 spices
Piper has : 3/12(144) = 432/12 = 36 spices
Phoebe has : 4/12(144) = 576/12 = 48 spices <====
Answer:
48 spices
Step-by-step explanation:
The number of spices each has is a multiple of 5, 3, and 4.
The number of spices each has is 5x, 3x, and 4x.
Pru has 5x spices.
Piper has 3x spices.
Pru has 24 more spices than Piper, so
5x = 3x + 24
2x = 24
x = 12
Phoebe has 4x spices, so Phoebe has
