A store gives a 15% discount to reward members? What is the discount on $215 worth of merchandise
To find the discount on $215 worth of merchandise with a 15% discount, you can use the following steps:
1. Calculate the discount amount as a percentage of the original price:
discount amount = original price x discount rate
discount amount = $215 x 0.15
discount amount = $32.25
2. Subtract the discount amount from the original price to find the sale price:
sale price = original price - discount amount
sale price = $215 - $32.25
sale price = $182.75
Therefore, the discount on $215 worth of merchandise with a 15% discount is $32.25. The sale price after the discount is $182.75.

x????
Answer:
x=-1
Step-by-step explanation:
4x+35x-15=9x-45
39x-15=9x-45
39x-9x=-45+15
30=+-30
x=-1
Answer:
\( \sf \: x = - 1\)
Step-by-step explanation:
Given equation,
→ 4x + 5(7x - 3) = 9(x - 5)
Now the value of x will be,
→ 4x + 5(7x - 3) = 9(x - 5)
→ 4x + 35x - 15 = 9x - 45
→ 39x - 15 = 9x - 45
→ 39x - 9x = -45 + 15
→ 30x = -30
→ x = -30 ÷ 30
→ [ x = -1 ]
Hence, the value of x is -1.

In which month was the average number of hours worked by the website designers closest to 50 hours
- January
- February
- March
- April
The correct answer is March, as it was the month in which the average number of hours worked by the website designers was closest to 50 hours.
What is a month?A month is a unit of time typically consisting of 30 or 31 days. It is used for measuring periods of time, for example, when we say something happened "a month ago". Months are used in both the Gregorian calendar and the Julian calendar.
This data was gathered from a survey of website designers, which was conducted to determine the average number of hours each month that these professionals spent working.
In January, the average number of hours worked was 46.5. In February, it was 48.8. However, in March, the average number of hours worked was 49.4, which was the closest to 50 hours. This was followed by April, in which the average was 49.7.
Overall, it can be concluded that March was the month in which the average number of hours worked by website designers was closest to 50 hours. This is important data for website designers, as it allows them to understand the amount of time they should be spending on their work in order to be successful. It also helps employers gauge the workload of their website designers and ensure they are providing an adequate amount of work.

1. Write an equation that represents the distance Jamie will run in kilometers (d) at a rate of r kilometers
per hour.
2.How far will Jamie run
if they choose a rate of 8 kilometers per hour?
1. The equation that represents distance Jamie will run in kilometers (d) at a rate of r kilometers per hour is d = 0.5r
2. The distance Jamie will run if he chooses a rate of 8 kilometers per hour is 4 Km
What is speed?Speed is the distance travelled per unit. Mathematically, it can be expressed as:
Speed = distance / time
with the above formula, we give the various answers to questions. Details below
1. How to determine the equationTime = 1/2 = 0.5 hourSpeed = r Km/hDistance = d KmEquation for the distance travelled =?Speed = distance / time
r = d / 0.5
Cross multiply
d = r × 0.5
d = 0.5r
Thus, the equation to determine the distance travelled is d = 0.5r
How to determine the distance travelledUsing the equation d = 0.5r, we can determine the distance travelled at a rate of 8 Km/h as illustrated below:
Time = 1/2 = 0.5 hourSpeed (r) = 8 Km/hDistance (d) = ?d = 0.5r
d = 0.5 × 8
d = 4 Km
Thus, the distance travelled at a rate of 8 Km/h in 1/2 hour is 4 km

The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.
Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.
We have:
z₁ = 7(cos(577°) + i sin(577°))
Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.
From the given information, we have:
z₂ = 21(cos(-7°) + i sin(-77°))
To find the quotient, we divide z₁ by z₂:
z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]
Substituting the given values, we have:
z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]
= (7/21) * [cos(584°) + i sin(584°)]
The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

A quadratic function g(x) passes through the points (-8, 33), (2, 1), and (8, 1).
By applying the features of polynomials, the quadratic function g(x) = (1/5) · x² - 2 · x + 21/5 passes through the points (x₁, y₁) = (-8, 33), (x₂, y₂) = (2, 1) and (x₃, y₃) = (8, 1).
How to derive a quadratic function that passes through three points
Polynomials are algebraic expressions of the form \(\sum \limits_{i=0}^{n} c_{i}\cdot x^{i}\), where \(c_{i}\) is the i-th coefficient of the polynomial and n is the grade of the polynomial. In addition, we know that polynomials have n + 1 coefficients.
In the case of quadratic functions, the grade is 2 and the function have three coefficients. Hence, we need three distinct points to determine all the coefficients of a quadratic function.
(x₁, y₁) = (-8, 33)
64 · a - 8 · b + c = 33 (1)
(x₂, y₂) = (2, 1)
4 · a + 2 · b + c = 1 (2)
(x₃, y₃) = (8, 1)
64 · a + 8 · b + c = 1 (3)
Then, we find the solution of this system of linear equations:
a = 1/5, b = -2, c = 21/5
By applying the features of polynomials, the quadratic function g(x) = (1/5) · x² - 2 · x + 21/5 passes through the points (x₁, y₁) = (-8, 33), (x₂, y₂) = (2, 1) and (x₃, y₃) = (8, 1).

Answer: $
A single lottery ticket costs $2. Compute the Expected Value, to you, if you purchase 10,000 lottery tickets. Round your answer to the nearest dollar.
Answer: $
Step-by-step explanation:
The order of the numbers doesn't matter, so we'll use combinations instead of permutations. The number of combinations is:
₄₅C₈ = 215,553,195
So the probability of a ticket having the winning combination is 1 / 215,553,195.
The expected value to the state is:
E(X) = 10,000 (1) ($2) + 10,000 (1 / 215,553,195) (-$1,000,000)
E(X) = $19954
The expected value to you is:
E(X) = 10,000 (1) (-$2) + 10,000 (1 / 215,553,195) ($1,000,000)
E(X) = -$19954
The position of a body moving along the x-axis is given by s = t³ - 12t2+36t, with s in meters and t in seconds.
Find the total distance traveled by the body from t = 0 tot = 4.
Total distance =
The total distance travelled by the body is 48 meters
According to the question we have been given an equation of the position of a body moving along x-axis as
s = t³ - 12t² + 36t
where, s = distance in meters
t = time in seconds
We need to find the total distance traveled by the body from t=0s to t=4s
The formula for the total distance is given as :
S = |s(1) - s(0)| + |s(2) - s(1)| + |s(3) - s(2)| + |s(4) - s(3)|
Now we will find out the distance travelled in time 0s to 4s
when t = 0s , s = (0)³ - 12(0)² + 36*0
= 0m
t = 1s , s = (1)³ - 12(1)² + 36*1
= 25m
t = 2s , s = (2)³ - 12(2)² + 36*2
= 32m
t = 3s , s = (3)³ - 12(3)² + 36*3
= 27m
t = 4s , s = (4)³ - 12(4)² + 36*4
= 16m
Putting the required values in the above formula we get ,
S = |25-0|+|32-25|+|27-32|+|16-27|
S = 25 + 7 + 5 + 11 meters
S = 48 meters
Hence the total distance travelled by the body is 48 meters

Calculate the sector area: 16 in 90°
Therefore , the solution of the given problem of area comes out to be
r = 8.
Define area.The term "area" describes the amount of space occupied by a 2D form or surface. We use cm2 or m2 as our units for measuring area. A shape's area is determined by dividing its length by its breadth.
Here,
A 90 degree sector occupies 1/4 of a circle, which has 360 degrees. Consequently, the area of the whole circle can be written as
Sector Size/Sector Area = Circle Area/360
16 ft2/90 = n/360
(360) (16 ft2)/90 = n
(4)(16 ft2) = n
The total size of the circle is n = 64 ft2.
Since Area of a Circle equals r2,
∏r2 = 64
r2 = 64/∏
r = √(64/∏)
We multiply by / to get by rationalizing the denominator.
r = √(64∏)/√(∏2) Then using the denominator's square root, we can obtain the solution of
r = √(64∏)/∏
r = 8
Therefore , the solution of the given problem of area comes out to be
r = 8.

Death Valley has an elevation of-282 feet relative to sea level. Explain how to use absolute value to deceive the elevation of Death Valley as a positive integer
We can represent the elevation of Death Valley as 282 feet above sea level, using the absolute value to convert the negative value to a positive integer.
One way to use absolute value to represent the elevation of Death Valley as a positive integer is to take the absolute value of the negative elevation. Absolute value is a mathematical function that returns the magnitude of a number without considering its sign.
In this case, the elevation of Death Valley is -282 feet, but the absolute value of -282 is 282. Therefore, we can represent the elevation of Death Valley as 282 feet above sea level, using the absolute value to convert the negative value to a positive integer.
that this representation does not change the actual elevation of Death Valley, but it is a way to express the same information using a positive integer.
