What is the discount of a guitar with an original price of $95 and a discount of 15%.
Answer:
$80.75 dollars
Step-by-step explanation:
Given the following question:
Initial price = $95
15% discount
In order to find the answer, we have to find 15% of 95.
[tex]\frac{15\times95}{100} =15\times95=1425\div100=14.25[/tex]
[tex]95-14.25=80.75[/tex]
[tex]g=80.75[/tex]
The guitar (after a 15% discount) costs "$80.75 dollars."
Hope this helps.
A watch, after allowing a discount of 15% on its marked price, was sold at a gain of 20%. Had it been sold after allowing 25% discount there would have been gain of Rs. 120. Find the cost price of the watch.
Answer:
Answer:1200
Step-by-step explanation:
Consider the cost price to be x.
1st equation x - (15/100)x = x + (20/100) ...15% discount and gain of 20%
2nd equationx - (25/100)x = x + 120 ....25% discount and a gain of 120Rs
Solving above equations by subtracting we get
(10/100)x = (20/100)x - 120
Solving LHS and RHS..(10/100)x =120
x=1200

A square playground has an area of 10,000ft^2. What is the length of one of the slides of the playground?
Answer:
100 feet in length
Step-by-step explanation:
Given the following question:
[tex]A=s^2[/tex]
In order to find the area of the square we have to multiply two of the lengths by itself.
[tex]A=s^2[/tex]
[tex]A=100^2[/tex]
[tex]A=100\times100[/tex]
[tex]100\times100=10000[/tex]
[tex]=10000ft^2[/tex]
Which means one side of the given square is "100 feet."

he area of a rectangular piece of metal is 20 square centimeters. The perimeter is 18 centimeters. What are the dimensions of the piece?
Answer:
5 cm by 4 cm
Step-by-step explanation
A = L x W 20 = L x W
P = 2L + 2W (18 = 2L + 2W)/2
9 = L + W W = 9 - L
20 = L (9 - L) 20 = 9L - L^2
L^2 - 9L + 20 = 0 (L - 4)(L - 5) = 0
L = 4 L = 5
The longer one is the length, so L = 5, and W = 4.

The value of [tex]sin^4\theta+cos^4 \theta[/tex] will be [tex]\frac{2}{(\sqrt{2})^4}[/tex]
Trigonometry identityGiven the expression
sin θ – cos θ = 0
This can be simplified further as:
sin θ = cos θ
sin θ/cosθ = cosθ/cosθ
tanθ = 1
θ = arctan(1)
θ = 45 degrees
To evaluate [tex]sin^4\theta+cos^4 \theta[/tex], substitute the value of theta into the expression to have:
[tex]sin^4\theta+cos^4 \theta\\=sin^445+cos^4 45\\=(\frac{1}{\sqrt{2}} )^4+(\frac{1}{\sqrt{2}} )^4\\=2(\frac{1}{(\sqrt{2})^4} )[/tex]

Alan saves $180 each month. How much has Alan saved after 3 years?

Answer:
$6,480
Step-by-step explanation:
[tex]180(12)(3)=6,480[/tex]
Hope this helps
Answer:
#540
Step-by-step explanation:
Alan saved $180 in each month
and we have 12 months in a year so we say
$180=12
x=36
here we cross multiply then we have 180 * 36 which is equal to $6480 after that we divide it by 12 and that's $540
Note: I got 36 months because 12 months in a year so multiply by three years that's 36 months
Help!!! Use 1st and 2nd differences to determine if the following table is linear, quadratic or neither.
Given the second difference, the table is quadratic.
What are linear and quadratic equations?A linear function is a function that has a single variable raised to the power of 1. An example is x + 2. A quadratic function is a function that usually has a single variable and it is raised to the power of 2. An example is 2x² + 10x + 25.
What are the first and second differences?First differences:
21 - 11 = 10
35 - 21 = 14
53 - 35 = 18
75 - 53 = 22
Due to the fact that the first difference is not the same, the function is not a linear function.
Second difference:
14 - 10 = 4
18 - 14 = 4
22 - 18 = 4
Due to the fact that the second difference is fairly constant, the function is a quadratic function.

Steven borrows $60,000 for school. The intrest rate is 6.5%. He wants to pay off the loan in 12 years. What would be the simple intrest rate?
Answer:
i think it is $106,800.00
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6.5%/100 = 0.065 per year.
Solving our equation:
A = 60000(1 + (0.065 × 12)) = 106800
A = $106,800.00
The total amount accrued, principal plus interest, from simple interest on a principal of $60,000.00 at a rate of 6.5% per year for 12 years is $106,800.00.
The simple interest rate for this loan is 78%.
What is simple interest?It is the interest calculated on the principal at a given rate for a time period.
We have,
If Steven borrows $60,000 at an interest rate of 6.5%, the total amount of interest he will pay over 12 years can be calculated as:
I = Prt
where I is the interest, P is the principal amount borrowed ($60,000), r is the interest rate as a decimal (0.065), and t is the time period in years (12). Substituting the given values, we get:
I = 60000 x 0.065 x 12
I = $46,800
The simple interest rate is the ratio of the total interest paid to the principal borrowed, expressed as a percentage:
simple interest rate = (total interest/principal borrowed) x 100
Substituting the given values, we get:
simple interest rate = (46800 / 60000) * 100
simple interest rate = 78%
Therefore,
The simple interest rate for this loan is 78%.

Ben stayed in three different cities (Washington, D.C., Atlanta, Georgia, and Dallas, Texas) for a total of 14 nights. He spent three
times as many nights in Dallas as he did in Washington. The total cost for 14 nights (excluding tax) was $2230. Determine the
number of nights that he spent in each city.
City Cost per Night
Washington $200
$140
Dallas
$150
Atlanta
Answer:
Step-by-step explanation:
w + a + d = 14
d = 3w
200w + 150a + 140d = 2230
w + a + 3w = 14
4w + a = 14 Eq. 1
200w + 150a + 140d = 2230
20w + 15a + 14(3w) = 223
62w + 15a = 223 Eq. 2
Eq. 1 & Eq. 2
4w + a = 14
62w + 15a = 223
-60w - 15a = -210
62w + 15a = 223
2w = 12

now , angle 1+ angle x + 18 = 180 { because of angle sum property }

Explanation:
The given slope is [tex]m = \frac{4}{3}[/tex] and the line goes through the point [tex](x_1,y_1) = (3,-1)[/tex]
This means [tex]x_1 = 3 \ \text{ and } \ y_1 = -1[/tex]
We will plug this information into the point-slope formula below and simplify.
[tex]y - y_1 = m\left(x - x_1\right)\\\\y - (-1) = \frac{4}{3}\left(x - 3\right)\\\\y + 1 = \frac{4}{3}\left(x - 3\right)\\\\[/tex]
