Answer:
[tex]\mathrm{1.\:D.\:8.4\%}\\\mathrm{2.\:C.\: \$96.60}\\\mathrm{3.\:D.\: \$227.85}\\\mathrm{4.\:B.\:\$490}[/tex]
Step-by-step explanation:
1. The car's initial price was $273. Since the sale price is $250, the car is on a [tex]273-250=\$23[/tex] discount. The percent of discount is the discount price over the initial price:
[tex]\frac{23}{273}\approx \fbox{$8.4\%$}[/tex].
2. Since the weight racks were initially priced $46, then marked up 210%, their mark-up is:
[tex]46\cdot2.1=\fbox{$\$96.60$}[/tex]
*Worth noting that this is the mark-up (as the question is asking), not the total price after the mark-up.
3. The TV's initial price is $325.50. If it's on sale for 30%, it's final price will be [tex]100\%-30\%=70\%[/tex] of the initial price:
[tex]\$325.50\cdot 0.7=\fbox{$\$227.85$}[/tex]
4. The final retail price will be the initial price + the mark-up:
[tex]280+280(0.75)=\fbox{$\$490$}[/tex].

Identify the function by that reflects f(x)=5x^3-3 across the x axis and shifts up 2 units
The new function after reflected across the x-axis and shifts up 2 units is g(x)= -5x³+5.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is f(x)=5x³-3.
When a function f(x) is reflected over the x-axis, it becomes a new function g(x)= -f(x).
The given function reflected across the x-axis and shifts up 2 units.
Now, g(x)= -(5x³-3)+2
= -5x³+3+2
= -5x³+5
Therefore, the new function after reflected across the x-axis and shifts up 2 units is g(x)= -5x³+5.

Find the value of x. Round your answer to
the nearest tenth. Please help
Answer:
x=50.7°
Step-by-step explanation:
Use the given angle of x° to find which trigonometry ratio to use. We are given the side adjacent to the angle and the hypotenuse. Therefore, we use the cosine ratio:
[tex]cosineX=\frac{adjacent}{hypotenuse}[/tex]
Insert the given values:

Answer:
Step-by-step explanation:
y=a*b^x
a=$2,000
This is the amount that the homeowner borrowed from the lender
b=This would be represented as 1.04 in decimal form
The reason why it is 1.04 is that the 1 aka 100% counts as 2,000 which is the whole thing as well as 0.04 or 4% percent of the total amount($2000)
x= You would leave this as x because they did not give a value and the equation is written so that it could be used to solve the amount of money owed after 'x' years or a certain number of years
Therefore the equation would be y=2000*(1.04)^x

Someone please help me I only have until January 18th to turn this in. Question: Mr Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs 37 1/2 pounds pet bag. What is the total weight, in tons, of the dog food Mr. Lopez delivers to the animal shelter?
Answer:
Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.
Step-by-step explanation:
Mr Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs 37 1/2 pounds pet bag.
The weight of 1 bag of dog food = [tex]37\frac{1}{2}\text{ pounds }[/tex]
The weight of 40 bags of dog food = [tex]40 \times 37\frac{1}{2} =1500 \text{ pounds }[/tex]
Each pallet weighs = 1500 pounds
2 pallets weighs = 1500×2=3000 pounds.
We know that 2000 pounds = 1 ton
[tex]\frac{3000}{2000} \text{ pounds}=1.5 \text{ tons}[/tex]
Hence, Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.

The figure below shows a square ABCD and an equilateral triangle DPC:
ABCD is a square. P is a point inside the square. Straight lines join points A and P, B and P, D and P, and C and P. Triangle D
Jake makes the chart shown below to prove that triangle APD is congruent to triangle BPC:
Statements Justifications
In triangles APD and BPC; DP = PC Sides of equilateral triangle DPC are equal
Sides of square ABCD are equal
In triangles APD and BPC; angle ADP = angle BCP Angle ADC = angle BCD = 90° and angle ADP = angle BCP = 90° − 60° = 30°
Triangles APD and BPC are congruent SAS postulate
Which of the following completes Jake's proof? (1 point)
In triangles APD and BPC; AD = BC
In triangles APD and BPC; AP = PB
In triangles APB and DPC; AD = BC
In triangles APB and DPC; AP = PB.
9514 1404 393
Answer:
(a) In triangles APD and BPC; AD = BC
Step-by-step explanation:
We're not concerned with triangle APB, eliminating the last 2 choices.
We're not concerned with sides AP and BP, as they're not sides of the square, eliminating the second choice.
The choice that makes any sense in the proof is ...
In triangles APD and BPC; AD = BC

Abey and Anoki are eating chocolate bars. The bars are the same size. Abey has ! 3 4 ! Left. Anoki has ! 7 8 ! Left. How much chocolate is left altogether?
Answer:
13/8 of the chocolate will be left altogether.
Step-by-step explanation:
Given that,
Abey and Anoki are eating chocolate bars. The bars are the same size.
Abey left 3/4 of chocolate and Anoki left 7/8 of chocolate.
Left amount = Abey left amount + Anoki left amount
[tex]=\dfrac{3}{4}+\dfrac{7}{8}\\\\=\dfrac{3(2)+7(1)}{8}\\\\=\dfrac{6+7}{8}\\\\=\dfrac{13}{8}[/tex]

A repairman charges an inspection fee plus $22 per hour. A customer with a coupon for 40% off the inspection fee pays $118 for a 4-hour repair. How many hours are worked when a customer pays $94 without a coupon?
Answer:
Inspection fee = $50
h = 2 hours
Step-by-step explanation:
Let
x = the inspection fee
Charge per hour = $22
Number of hours = 4
A customer with a coupon for 40% off the inspection fee
This means the customer paid 60% of the inspection fee
118 = 60% of x + 22(4)
118 = 0.6x + 88
118 - 88 = .6x
30 = .6x
x = 30/0.6
x = $50
Inspection fee = x = $50
How many hours are worked when a customer pays $94 without a coupon?
94 = 50 + 22h
94 - 50 = 22h
44 = 22h
h = 44/22
h = 2 hours

What is the value of the expression below when x = 7?
5x - 7
Can I get some help here?
Answer:
AB, CB, AC
Step-by-step explanation:
All the angles in a triangle added up equal 180 degrees
Start by finding the measure of angle A
A + 86 + 27 = 180
A + 113= 180
A = 67 degrees
Now order them
86 is greater than 67 and 27 so B is the greatest
27 is less than 86 and 67 so C is the smallest
67 is less than 86 but greater than 27 so A is in the middle
Now for the sides..
AB is opposite angle C so it's the shortest
CB is opposite angle A so it's in the middle
AC is opposite angle B so it's the longest

(5x + 5 - 2x)(4 + 7x - 1)
Answer: 21x^2 + 44x + 15
Step-by-step explanation:
first, i used the distributive property.
5x x (4 + 7x - 1) + 5 (4 + 7x - 1) - 2x x (4 + 7x - 1)
then, i removed the parentheses.
20x + 35x^2 - 5x + 20 + 35x - 5 - 8x - 14x^2 + 2x
then, i collected the like terms.
44x + 21x^2 + 15
finally, i reordered the terms.
