In the mail, you receive a coupon for $5 off for a pair of jeans, which is represented by the function j(x)=x−5. When you arrive at the store, you find that all jeans are 25% off, which is represented by the function s(x)=0.75x. Which of the functions below represents how much you would pay for a pair of jeans, C(x)=s(j(x)) , if you use the coupon first followed by applying the discount from the store? (Do not consider tax.)
A .C(x)=0.75x−5
B .C(x)=0.75(x−5)
C .C(x)=0.75x−x−5
D .C(x)=x−5−0.75
Answer: B
Step-by-step explanation: The function C(x) = s(j(x)) shows you how to solve it.
First in the parenthesis j(x) so you have to substitute since they told you
j(x) = x-5
Next s(x-5) and s(x-5) = 0.75(x-5) through substitution
a car completes a 200km journey at an average speed of xkm/h. the car completes the return journey of 200 km at an average speed of (x+10)km/h. show that the difference of the time taken for each of the two journeys is 2000/x(x+10) hours
Answer:
The difference of the time taken for each of the two journeys is given as follows;
The difference of time = 2000/(x·(x + 10))
Step-by-step explanation:
The speed with which the car completes the 200 km journey = x km/h
The speed with which the car completes the return journey = (x + 10) km/h
Let t₁ represent the time it takes the car to complete the 200 km and let t₂ represent the time it takes the car to complete the return journey, we have;
t₁ = 200/(x)
t₂ = 200/(x + 10)
The difference of the time taken for each of the two journeys = t₁ - t₂
We have;
t₁ - t₂ = 200/(x) - 200/(x + 10)
200/(x) - 200/(x + 10) = (200·(x + 10) - 200·x)/((x)·(x + 10)) = 2000/((x)·(x + 10))
∴ t₁ - t₂ = 2000/((x)·(x + 10)) = 2000/(x·(x + 10))
The difference of the time taken for each of the two journeys = t₁ - t₂ = 2000/(x·(x + 10))

The washing machine had a selling price of P4,792. It had been marked up by P1,248. What was the cost? What was the mark-up rate?
Answer:
The cost of the washing machine is P 3,544
The mark-up rate is 35.21%
Step-by-step explanation:
1. We want to calculate the cost
Mathematically, this is the difference between the selling price and the mark up
We have this as;
4,792 - 1,248 = P 3,544
2. Here, we want to calculate the mark-up rate
Mathematically, this is the percentage of mark-up
That is;
mark-up/cost price * 100%
: 1,248/3,544 * 100% = 35.21%

Nikki drew a rectangle with a perimeter of 18 units on a coordinate grid. Two of the vertices were (4, –3) and (–1, –3). What could be the coordinates of the other two vertices of the rectangle?
Answer:
There are two possible solutions for the other two vertices of the rectangle:
(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)
Step-by-step explanation:
Geometrically speaking, the perimeter of a rectangle ([tex]p[/tex]) is:
[tex]p = 2\cdot b + 2\cdot h[/tex] (1)
Where:
[tex]b[/tex] - Base of the rectangle.
[tex]h[/tex] - Height of the rectangle.
Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:
[tex]b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}[/tex]
[tex]b = 5[/tex]
If we know that [tex]p = 18[/tex] and [tex]b = 5[/tex], then the height of the rectangle is:
[tex]2\cdot h = p-2\cdot b[/tex]
[tex]h = \frac{p-2\cdot b}{2}[/tex]
[tex]h = \frac{p}{2}-b[/tex]
[tex]h = 4[/tex]
There are two possible solutions for the other two vertices of the rectangle:
(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

A cylinder shaped water tank has a diameter of 8 m and a height of 20 m.
What volume of water does the tank contain when it is 60% full?
Use 3.14 to approximate pi.
Enter your answer as a decimal to the hundredths place in the box.
___ m3
Answer:
602.88 cu ft.
Step-by-step explanation:
V = Bh where B is the area of the base, which is a circle in your problem.
Since the diameter is 8, the radius is 4.
So, B = [tex]\pi r^{2} = 3.14(4^{2} ) = 3.14(16) = 50.24[/tex]
V = Bh = 50.24(20) = 1004.8 cu ft = total volume of tank
60% of that volume is .60(1004.8) = 602.88 cu ft.
Put the following equation of a line into slope-intercept form, simplifying all fractions.
Answer:
y=1/2x-2
Step-by-step explanation:
2y=-4+x
2y=x-4 divide both sides by 2
y=1/2x-4/2
y=1/2x-2
Answer:
[tex]y = 0.5x - 2[/tex]
Step-by-step explanation:
Slope intercept form is
[tex]y = mx + b[/tex]
Our initial goal is to isolate y.
[tex]2y - x = -4[/tex]
Add x to both sides of the equation.
[tex](2y - x) + x = (-4) + x[/tex]
Simplify.
[tex]2y =x -4[/tex]
Divide both sides by 2.
[tex]\frac{2y }{2} = \frac{(x - 4)}2}[/tex]
Simplify.
[tex]y = 0.5x - 2[/tex]

Answer:
1232 is the volume because 16×7×11
Answer:
The volume is 1,232 ft³
Step-by-step explanation:
Volume = lwh = Length × Width × Height =
[given that the length is 16, width is 7, and height is 11]
16 × 7 × 11
4 × 4 × 7 × 11

________
The volume is the measurable capacity of an object or the metrical space that something holds or takes up.
Just like you multiply the net length and width to find the area of a 2 dimensional object, you can extend that 2d object so that is has height by multiplying by the given height.

Answer:
a. 18
b.144
c.108
Step-by-step explanation:
Using the given, Angle R equal 5x-54 and Angle T is 8u.
Also RS is congruent to ST. Since SR is congruent to ST, their opposite angles are also congruent using base angle theorem. So angle R is equal to Angle T. However, STU is a exterior angle so STU isn't congruent to SRT.
However, we can add , interior angle T, and STU to 180 to find x.
Interior angle T=SRT so interior angle t=5x-54.
Set up equation
[tex]5x - 54 + 8x = 180[/tex]
[tex]13x - 54 = 180[/tex]
[tex]13x = 234[/tex]
[tex]x = 18[/tex]
b.Plug 18 into 8x
[tex]8(18) = 144[/tex]
STU=144
c. Using the triangle exterior angle theorem, the exterior angle is equal to the measure of the sum of two non adjacent angles.
Angle S and Angle R are the non adjacent angle to STU.
So we cast up this equation.
[tex]5x - 54 + s = 180[/tex]
plug 18 in for x
[tex]5(18) - 54 + s = 144[/tex]
[tex]90 - 54 + s = 144[/tex]
[tex]36 + s = 144[/tex]
s=108

Answer:
System is given belowStep-by-step explanation:
Let (applicable to all three lines below)Hard candy = x kg with price $1.60/kgGummy worms = y kg with price $2.20/kgTotal weight = 50 kg with mixed price $1.75/kgRequired equations:
x + y = 50 total weight1.60x + 2.20y = 50*1.75 total price=========================================
Note. It says don't solve but the solution below for those who is interested to know the answer.
Simplify the second equation and solve by substitution x = 50 - y:
1.6(50 - y) + 2.2y = 87.580 - 1.6y +2.2y = 87.50.6y = 7.5y = 7.5/0.6y = 12.5Find the value of x:
x = 50 - 12.5 = 37.5Hard candy = 37.5 kg and gummy worms = 12.5 kg

h=

i=

Step-by-step explanation:
The values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.
What is the matrix?It is defined as the group of numerical data, functions, and complex numbers in a specific way such that the representation array looks like a square, rectangle shape.
We have a matrix A shown in the picture:
| 2 3 3 |
A = | 3 1 2 |
| 7 8 9 |
It is required to find the inverses of a matrix.
To find the inverse of a matrix:
Augment with a 3x3 identity matrix
[tex]=\begin{bmatrix}2&3&3&\mid \:&1&0&0\\ 3&1&2&\mid \:&0&1&0\\ 7&8&9&\mid \:&0&0&1\end{bmatrix}[/tex]
Convert the matrix to the identity matrix.
[tex]=\begin{bmatrix}1&0&0&\mid \:&\frac{7}{2}&\frac{3}{2}&-\frac{3}{2}\\ 0&1&0&\mid \:&\frac{13}{2}&\frac{3}{2}&-\frac{5}{2}\\ 0&0&1&\mid \:&-\frac{17}{2}&-\frac{5}{2}&\frac{7}{2}\end{bmatrix}[/tex]
Simply it:
[tex]=\begin{pmatrix}\dfrac{7}{2}&\dfrac{3}{2}&-\dfrac{3}{2}\\ \dfrac{13}{2}&\dfrac{3}{2}&-\dfrac{5}{2}\\ -\dfrac{17}{2}&-\dfrac{5}{2}&\dfrac{7}{2}\end{pmatrix}[/tex]
From the inverse matrix the values of unknows can be find:
a = 7/2
b = 3/2
c = -3/2
d = 13/2
e = 3/2
f = -5/2
g = -17/2
h = -5/2
i = 7/2
Thus, the values of the a, b, c, d, e, f, g, h, and i can be calculated after finding the inverse of a matrix.

Simplify the expression
8.8 (3.6d +1)
Answer:
31.68d + 8.8
Step-by-step explanation:
We have to simplify the expression but with one dillemma. The number 8.8 is outside the parenthesis of 3.6d + 1 and 3.6d + 1 aren't combinable because they aren't like terms.
When we have a problem like 8.8 being out of the parenthesis, we need to distribute 8.8 to both numbers in the parenthesis, or in other terms multiplying.
(8.8 * 3.6d + 1 * 8.8)
31.68d + 8.8
