What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
You are buying a $24.50 item that has 6% sales tax.
And, You give the cashier $40 to pay for the item.
Here, You are buying a $24.50 item that has 6% sales tax.
Hence, The amount of sales tax = 6% of $24.50
= 6/100 × $24.50
= $1.47
Thus, The amount of charge = $40 - ($24.50 + $1.47)
= $40 - $25.97
= $14.03

A. 1/3x2y cm3
B. 1/2xy2 cm3
C. 1/3xy cm3
D. 1/2x2y cm3
This is all the info I am given HELP
Answer: Th answer is A
The area of the base of each pyramid, if divided from a square base of entire length x inches and made of 8 pyramids, should be 1/8 x[tex]^[/tex] in.2, but among given options, B. 1/4 x[tex]^[/tex] in.2 is closest. The volume of a solid right pyramid with square base edge length x cm and height y cm is correctly given by A. 1/3 x[tex]^[/tex]y cm3.
Explanation:To find the area of the base of each pyramid in a soundproofing tile made of 8 identical solid right pyramids with square bases, we will calculate the area of the entire square base of the tile and then divide by the number of pyramids. If the length of the whole tile is x inches, the area of the whole base is x[tex]^[/tex] square inches. Since there are 8 pyramids, the area of the base of each pyramid is x^2 divided by 8, which simplifies to 1/8 x[tex]^[/tex] square inches. However, this option is not listed, suggesting there may have been an error in the question or choices provided. Regardless, among the given options, the closest would be B. 1/4 x[tex]^[/tex] in.2, considering the whole square is likely split into quarters for each pyramid.
For the volume of a solid right pyramid with a square base with an edge length of x cm and a height of y cm, the formula for the volume of the pyramid is 1/3 times the area of the base times the height. The area of the base, which is a square, is x[tex]^[/tex], so the volume is 1/3 x[tex]^[/tex]y cm3. Therefore, the correct answer is A. 1/3 x[tex]^[/tex]y cm3.

The diagram represents the enlargement of a rectangle by using a scale factor of 6
5*1 is the dimension of the original rectangle.
What is Scale?The scale is the proportion that is used to show how the dimensions of a model or scaled figure compare to the equivalent dimensions of the real figure or item. In contrast, a scale factor is a number that is multiplied by each component of an item to create an expanded or reduced figure.
Given With a scale factor of 6, the diagram depicts the expansion of a rectangle.
and the new rectangle is 30*6 in size.
The scaling factor is 6
thus,
the length of the original rectangle = 30/6
the length of the original rectangle = 5
the width of the original rectangle = 6/6
the width of the original rectangle = 1
therefore, the dimension of the original rectangle is 5*1.

A chemist weighed out 101. g of potassium. Calculate the number of moles of potassium she weighed out.
Round your answer to 3 significant digits.
Answer:
101 g of Potassium is equivalent to 2.583 moles of Potassium.
Step-by-step explanation:
As per definition of moles, molecular weight of a substance = 1 mole
So molecular weight of Potassium = 39.0983 g
∵ 39.0983 g weight of Potassium = 1 mole
∴ 1 g weight of Potassium = [tex]\frac{1}{39.0983}[/tex] g
∴ 101 g of Potassium = [tex]\frac{101}{39.0983}[/tex] g
= 2.583 moles
Therefore, 101 g of Potassium is equivalent to 2.583 moles of Potassium.

Which of the following ordered pairs is a possible solution to the equation y = 3x - 2?
A: (0, 2)
B: (1, 1)
C: (-3, 1)
D: (2, 0)
The only ordered pair that is a possible solution to the equation y = 3x - 2 is B: (1, 1).
To determine if an ordered pair is a possible solution to the equation y = 3x - 2, we need to check if the x and y values satisfy the equation when substituted into it.
Let's check each option:
A: (0, 2)
Substitute x = 0 and y = 2 into the equation:
2 = 3(0) - 2
2 = -2
This is not true, so (0, 2) is not a possible solution.
B: (1, 1)
Substitute x = 1 and y = 1 into the equation:
1 = 3(1) - 2
1 = 1
This is true, so (1, 1) is a possible solution.
C: (-3, 1)
Substitute x = -3 and y = 1 into the equation:
1 = 3(-3) - 2
1 = -11
This is not true, so (-3, 1) is not a possible solution.
D: (2, 0)
Substitute x = 2 and y = 0 into the equation:
0 = 3(2) - 2
0 = 4
This is not true, so (2, 0) is not a possible solution.
The only ordered pair that is a possible solution to the equation y = 3x - 2 is B: (1, 1).

1 you have 75% of your pay direct/-deposit how much is given to you as a check per week ?
2. of the amount direct-deposited problem 1 you have 50% placed into a savings account how much is deposited in the savings account each month?,
Final answer:
The student takes home a check of $25.94 each week after deductions and direct deposit. Of the amount direct-deposited, $38.92 is placed into a savings account weekly, resulting in $155.68 being deposited into the savings account monthly.
Explanation:
To solve the first problem, we must start by calculating the gross income for one week of work:
Gross income = Hourly rate × Hours worked per week = 13.76 × 10 = $137.60Next, we calculate each of the deductions from the gross income:
FICA = Gross income × FICA rate = $137.60 × 7.65% = $10.52Federal tax withholding = Gross income × Federal tax rate = $137.60 × 9.8% = $13.48State tax withholding = Gross income × State tax rate = $137.60 × 7.13% = $9.82Now we calculate the total deductions:
Total deductions = FICA + Federal tax + State tax = $10.52 + $13.48 + $9.82 = $33.82The net income after deductions is:
Net income = Gross income - Total deductions = $137.60 - $33.82 = $103.78We then determine the amount directly deposited:
Direct deposit amount = Net income × Direct deposit percentage = $103.78 × 75% = $77.84The remaining paycheck given as a check each week is:
Check amount = Net income - Direct deposit amount = $103.78 - $77.84 = $25.94For the second question, we already know from the scenario that $77.84 is directly deposited. We just need to calculate the amount that goes into the savings account:
Savings deposit per week = Direct deposit amount × Savings account percentage = $77.84 × 50% = $38.92 per weekTo find the monthly savings deposit, we assume there are 4 weeks in a month:
Savings deposit per month = Savings deposit per week × 4 = $38.92 × 4 = $155.68 per monthThaddeus wants to attend a sports camp this spring that costs $170.00 for the week. He rakes leaves during the fall and earns $58.35. He shovels snow during the winter and earns $85.80. How much more money does Thaddeus need to earn to pay for the sports camp? Write your answer as a decimal. Thaddeus needs to earn
He need $25.85 more to pay.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Charge for week = $170
earnings from leaves raking = 58.35
Earnings from snow shoving = 85.80
Total earnings = 85.80 + 58.35 = $144.15
So, he need more
=170 - 144.15
=$25.85
Hence, He need $25.85 more to pay.

What type of graph is useful when depicting piece rates?
A. Bar graph
B. Scatterplot
C. Slope
D. Linear graph
A linear graph is most useful when depicting piece rates as it clearly shows the continuous relationship and trend between the number of items produced and the pay received, represented by a positive, negative, or zero slope.
When depicting piece rates, which relate the payment an individual receives to the number of pieces produced or tasks completed, a linear graph or line graph is often most useful. Linear graphs effectively illustrate relationships between two variables, such as the number of items produced (on the x-axis) and the amount of money earned (on the y-axis), highlighting trends and changes over a range of values. A bar graph may be best to illustrate comparisons when showing the relationship of separate and distinct categories. However, in the context of piece rates, where there is a continuous relationship between work done and pay received, the connected data points in a line graph provide a clear visual of the rate of payment as it changes with the number of pieces.
Understanding the appearance of slopes is essential in reading graphs. A positive slope indicates an increase or upward trend in the relationship between the two variables, a negative slope represents a decrease or downward trend, and a zero slope indicates a consistent, flat relationship with no change over time.
