No, the cost of the laptop after applying sales tax is $455.79.(option c)
What is Sales tax ?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
We have,
Lewis saved dollar for a new laptop = 450 dollar
Laptop sticker price = 429.99 dollar
Sales tax rate = 6%
According to the question
Sales tax rate of 429.99 dollar
=429.99 × 6/100
= 25.7994
Total cause of the laptop
429.99+25.7994= 455.79
Hence, the cost of the laptop after sales tax is 455.79 dollar
Thus ,Lewis have not enough to purchase the laptop.

When the county fair opened its gates, 68 people entered the fairgrounds. After one hour, there were 1.5 times as many people on the fairgrounds as when the gates opened. After two hours, there were 1.5 times as many people on the fairgrounds as the previous hour. If this pattern continues, write the equation representing the number of people, y, at the fair x hours after the gates open.
Answer:
y=1.5x + 68
Step-by-step explanation:
68 is the starting value and it increases by 1.5 every hour.
Answer:
y = 68 ( 1.5) ^x
Step-by-step explanation:
This is exponential growth
The formula is
y = ab^x where a is the initial amount and b is the growth rate
The initial amount is 68 and the growth rate is 1.5
y = 68 ( 1.5) ^x

EXPLANATION= To find the least common denominator first convert all integers and mixed numbers (mixed fractions) into fractions. Then find the lowest common multiple (LCM) of the denominators.
A painting measures 1 meter by 2 meters. A frame shop charges $30.00 per meter for a wooden frame. How much would it cost to buy a frame for the painting?
Answer:
$180.00
Step-by-step explanation:
The painting is rectangular and it measures 1 meter by 2 meters. The frame shop charges $30.00 per meter for a wooden frame.
To find the cost, we need to find the perimeter of the painting and then multiply it by the cost of a wooden frame per meter.
The perimeter of a rectangle is:
P = 2(L + B)
P = 2(1 + 2) = 2 * 3 = 6 m
The cost of the frame is therefore:
6 * 30 = $180.00

On a multiple-choice test, each question has 4 possible answers. A student does not know the answers to three questions, so the student guesses. What is the probability that the student gets all three questions wrong? The probability that the student gets all three questions wrong is . What is the probability that the student gets all three questions right? The probability that the student gets all three questions right is .
Answer:
P(making 3 wrong guesses) = 27/64
P(making 3 right guesses) = 1/64
Step-by-step explanation:
Number of possible answers per question = 4
Number of right answer per question = 1
Number of wrong answers per question = (4 - 1) = 3
Probability = (Number of required outcomes / Number of Total possible outcomes)
A.) probability of guess 3 questions wrong :
Probability of making a wrong guess = (number of wrong options / total number of options
P(making a wrong guess) = 3/4
Therefore,
P(making 3 wrong guesses) = 3/4 × 3/4 × 3/4 = (27/64)
B.) probability of making 3 right guesses:
P(making a right guess) = (number of right options per question / total number of options per question)
P(making a right guess) = 1/4
P(making 3 right guesses) =(1/4 × 1/4 × 1/4) = 1/64

which number line represents the solution set for the inequality 3(8 - 4x) < 6(x - 5 )
Answer:
3 <x
Step-by-step explanation:
3(8 - 4x) < 6(x - 5 )
Divide each side by 3
3/3(8 - 4x) < 6/3(x - 5 )
8 -4x < 2(x-5)
Distribute
8 -4x < 2x-10
Add 4x to each side
8 -4x+4x < 2x+4x-10
8 < 6x-10
Add 10
8+10< 6x-10+10
18<6x
Divide by 6
18/6 < 6x/6
3 <x
Start by distributing on both sides of this inequality.
This gives you 24 - 12x < 6x - 30.
Put your x's together on the left by subtracting 6x from both sides.
This gives you 24 - 18x < -30.
Now subtract 24 from both sides to get -18x < -54.
Now divide both sides by -18 and x > 3.
Remember to switch the direction of the inequality sign
when you divide both sides by a negative number.

For 30 persons or fewer $10 per person. For every additional person $9 per person.Irene paid the company $390 for her department event. How many people did she cater for?
Answer:
She catered for 40 people.
Step-by-step explanation:
According to the information given, you can write an equation that indicates that 30 people multiply for its cost that is $10 plus the number of people after 30 for its cost that is $9 is equal to $390. According to this, the equation is:
10(30)+9x= 390, where
x= number of people after 30
Then, you can solve for x:
300+9x= 390
9x=390-300
9x= 90
x=90/9
x=10
The answer is that she catered for 40 people, 30 people at a cost of $10 and 10 people for a cost of $9.
when 5 is added to a certain number and the result is multiplied by 3, the final answer is 27. What is the original number
Answer:
Let the number be x
5 is subtracted from a certain number means it will be x - 5
The result is multiplied by 7, the final result is 63,
7 (x - 5) = 63
7x - 35 = 63
7x = 63 + 35
7x = 98
x = 98/7
x = 14
The number is 14
Answer the number is 14 and the equation is 7 (x - 5) = 63
Step-by-step explanation:
Using the appropriate arithmetic operation, the value of the original number is 4
Let the number be : p
5 added to p :
5 + pMultiply the addition by 7 :
(5 + p) × 3 = 27We can solve for p thus :
15 + 3p = 27
3p = 27 - 15
3p = 12
p = 12/3
p = 4
Therefore, the original number is 4.

What statement is false choose from the letters above that match the statements :-)
Please help guys!
Thanks
Answer:
Option C
Step-by-step explanation:
A "tessellation" is a flat covering of 2D geometric shapes. A shape in a tessellation is called a "tile".
Tessellations can be in a pattern that goes 'forever', and they cannot overlap. This eliminates A and D, since they are true.
A "tessellation" cannot have any spaces. This eliminates option B, since this is true. Since a circle and an eclipse have curved sides, they can not tessellate on their own. Regular pentagons and octagons will also not tessellate on it's own. Any shape that are put together and leave a gap will not tessellate.
I have attached a picture showing why circles and pentagons will not tessellate.
So, not any 2D shape would tessellate. Option C's statement is false.
Option C should be the correct answer.
