Answer: X = 17
Step-by-step explanation:
8.75 + 1.95x = 41.9
1.95x = 41.9 - 8.75
1.95x = 33.15
x = 33.15/1.95

Gombak Mega Store is having its Year-End-Sales. Ten percent, five percent and twenty percent discounts were given on shoes, handbags and watches respectively if two or more units of each item were bought. Noor bought three pairs of shoes, two units of handbag and one unit of watch. If the price (per unit) of shoes, handbag and watch is RM150, RM200 and RM250 respectively, how much money does Noor has to pay?
Answer:
$963.00
Step-by-step explanation:
.9(3x150) + .95(2x200) + 250
.9(450) + .95(400) + 250
405 + 308 + 250 = 963
If we are taking 10% off, that is like leaving 90% (.9) on.
If we are taking 5% off, that is like leaving 95% ( .95) on.
No discount for the watch because she only bought one.

decide if you are given enough information to prove that the quadrilateral is a parallelogram practice c
No, you are not given enough information to prove that the quadrilateral is a parallelogram.
In order to prove that the quadrilateral is a parallelogram, we must have four points to calculate the lengths of the sides and angles. We need to verify that the opposite sides of the quadrilateral are equal in length and that the opposite angles are equal. We can use the formula for the area of a parallelogram: A = b*h, where b is the length of the base and h is the height of the parallelogram. We can also use the formula for the sum of the angles of a quadrilateral: A1 + A2 + A3 + A4 = 360 degrees. Without having the four points, we cannot calculate the lengths of the sides or angles, so we cannot prove that the quadrilateral is a parallelogram.

If a fair die is rolled 3 times, what is the probability, to the nearest thousandth, of getting exactly 1 three?
The probability of getting exactly 1 three, to the nearest thousandth is 0.347.
What is Binomial Distribution?Binomial distribution is the distribution of a random variable X for which there are only two possibilities. The probability p for the success and the probability of 1-p for the failure, which consist of n trials.
The binomial distribution has the formula,
P(x) = ⁿCₓ pˣ (1-p)ⁿ⁻ˣ
where x : number of times for a specific outcome within n trials
p : probability of success in each trial
n : number of trials
Given that a fair die is rolled 3 times.
Here, n = 3, x = 1
p = probability of getting three for 1 trial = 1/6
1 - p = 1 - 1/6 = 5/6
P(1) = ³C₁ (1/6)¹ (5/6)³⁻¹
= 0.347
Hence the probability of getting exactly 1 three is 0.347.

Calculate the Scale Factor given the points A( 12, 4) and A' (9, 3).
The Scale Factor is 0.75, or 3/4
What is scale Factor?Scale factor is a ratio of two related lengths, areas, volumes, or other quantities. It is used to describe how a figure is enlarged or reduced in size. For example, when a figure is enlarged, the scale factor is greater than one, and when a figure is reduced, the scale factor is less than one. Scale factors can be used to calculate the lengths of sides and areas of figures when one side or area is known.
The Scale Factor is calculated by dividing the coordinates of point A' (9, 3) by the coordinates of point A (12, 4). Therefore, the Scale Factor is 0.75, or 3/4.

An Interval is all the numbers between two given numbers. 95% confidence level would result in a wider confidence interval.
What is interval in math?
A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1.Introducing intervals, bounded collections of numerical values that are highly helpful in explaining domain and range. To demonstrate where a value lies in relation to two endpoints, we can use interval notation. For instance, the expressions -3x2, [-3,2], and xR|-3x2 all denote that x is between -3 and 2, and either endpoint could be it.An inequality can be used to find an interval. The interval employs the inequality symbols to show whether the endpoints are included in the interval and uses the boundaries of the inequality as endpoints. The interval is defined as the values lying between the endpoints.Given data :
confidence interval = ( -11.98, -4.52)
-11.98≤x≤-4.52, [-11.98,-4.52], and {x∈ℝ|-11.98≤x≤-4.52} all mean that x is between -11.98 and -4.52 and could be either endpoint.

To find the value of f(g(-4)), we need to first substitute -4 into the definition of g(x) and then substitute the result into the definition of f(x).
First we substitute -4 into g(x):
g(-4) = 2(-4)^2 + 4(-4) - 8
g(-4) = 2(16) + (-16) - 8
g(-4) = 32 - 16 - 8
g(-4) = 8
Now we substitute 8 into f(x):
f(g(-4)) = f(8) = 2(8) - 4 = 16 - 4 = 12
So the value of f(g(-4)) is 12.
Answer:
28
Step-by-step explanation:
The expression: f(g(-4)) just means calculate the value of g at x = -4 and then calculate what f is equal to at that value g is equal to, so we have to first calculate g(-4) which we can do by substituting in -4 as x.
g(-4) = 2(-4)^2 + 4(-4) - 8
g(-4) = 2(16) - 8 - 8
g(-4) = 32 - 16
g(-4) = 16
Now from here we can substitute 16 as g(-4) in the expression f(g(-4)) which means we want to evaluate g(16) which we can do by substituting in 16 as x.
f(16) = 2(16) - 4
f(16) = 32 - 4
f(16) = 28
So that means f(g(-4)) = 28

The total amount paid with a monthly payment of $100 for a credit of $756.25 at an annual rate of 24.5% is $871.69.
What is a periodic payment?The periodic payment is the amount the car owner pays monthly to offset the balance on the credit card for purchasing new brakes.
The periodic payment is determined using an online finance calculator as follows:
N (# of periods) = 1 year
I/Y (Interest per year) = 24.5%
PV (Present Value) = $756.25
PMT (Monthly Payment) = $100

What is the cost of 6 pencils at 60 cents a dozen
To determine the cost of 6 pencils at 60 cents a dozen, we need to convert the price per dozen to the price per pencil. We know that a dozen is equal to 12, so we can use the following formula:
Price per pencil = (Price per dozen) / (Number of items per dozen)
So, in this case:
Price per pencil = (60 cents) / (12 pencils)
To convert cents to dollars, we divide by 100.
Price per pencil = (60/100) $ = 0.6 $
To find the total cost for 6 pencils we multiply the price per pencil by the number of pencils
Cost of 6 pencils = 6 * 0.6 = 3.6 $
So the cost of 6 pencils at 60 cents a dozen is 3.6 $.

h = (282.6 yd³)/(28.26 yd²) = 10 yd
The height of the cylinder is 10 yards.
The following inequalities form a system. y is greater than or equal to two-thirds times x plus 1 y is less than negative one-fourth times x plus 2 Which ordered pair is included in the solution to this system? (−6, 3.5) (−6, −3) (−4, 3) (−4, 4)
The ordered pair that is included in the solution to this system of inequalities is: B. (−6, −3)
How to determine the required ordered pair?In order to determine the ordered pair is included in the solution to this system of linear inequalities, we would first of all translate the word problem into an algebraic equation as follows;
y is greater than or equal to two-thirds times x plus 1 ⇒ y ≥ 2x/3 + 1.
y is less than negative one-fourth times x plus 2 ⇒ y < -x/4 + 2.
Next, we would use an online graphing calculator to graphically solve the system of linear inequalities. Therefore, the required solution for the given system of linear inequalities is the shaded area below the solid line, which is given by the ordered pair (−6, −3).

the dot product of two vectors with magnitudes of 10 and 6 is equal to 30. What is the angle formed by the vectors
If the magnitude of two vectors is 10 and 6 and their dot product is 30, then the angle between the vectors is 60°.
What is a vector?
A vector in mathematics is a quantity that not only expresses magnitude but also motion or position of an object in relation to another point or object. Euclidean vector, geometric vector, and spatial vector are other names for it.
There are two ways to define a dot product: algebraically and geometrically. The sum of the products of the matching entries of the two number sequences is the definition of the dot product in algebra. Geometrically, it is the sum of the cosine of the angle formed by the two vectors and their Euclidean magnitudes.
The magnitude of the vector 1 is, |a| = 10
The magnitude of the vector 2 is, |b| = 6
The dot product of the two vectors is, a·b = 30.
The formula for dot product of vectors is -
a·b = |a| |b| cos θ
Solve the equation to get the angle -
30 = (10 × 6) cos θ
30 = 60 cos θ
cos θ = 30/60
cos θ = 1/2
θ = cos^-1 (1/2)
θ = 60°
Therefore, the angle is obtained as 60°.
