A jeweler buys a ring from a jewelry maker for $125. He marks up the price by 135% for sale in his store. What is the selling price of the ring with 7.5% sales tax?
Answers
First, you would multiply 125*135%= 168.75
Then you would add 125 to 168.75 and you would get 293.75.
Next, you would multiply 293.75*7.5%= 22.03
Finally, add 22.03 to 293.75 and your answer is...

Use the x-values: 1, 2, 3, and 4 to write solutions of the equation y = 14x + 8 as ordered pairs.
Answers
For the equation y = 14x + 8, the ordered pairs with x values of 1, 2, 3, and 4, calculated by substituting these x-values into the equation, are (1,22), (2,36), (3,50), and (4,64).
Explanation:The equation in question is a linear equation, y = 14x + 8 , and you've been asked to use the x-values: 1, 2, 3, and 4 to write the solutions as ordered pairs. To find the corresponding y-values, substitute these x-values one by one into the equation.
For x = 1, y = 14*1 + 8 = 22, so the ordered pair is (1,22) For x = 2, y = 14*2 + 8 = 36, so the ordered pair is (2,36) For x = 3, y = 14*3 + 8 = 50, so the ordered pair is (3,50) For x = 4, y = 14*4 + 8 = 64, so the ordered pair is (4,64)
These points plotted on a graph represent the dependence of y on x.

To determine the solutions of the equation y = 14x + 8 for x-values 1, 2, 3, and 4, each x-value is substituted into the equation to find the corresponding y-values, resulting in ordered pairs (1,22), (2,36), (3,50), and (4,64).
Explanation:To find solutions of the equation y = 14x + 8 using the x-values 1, 2, 3, and 4, we will substitute each x-value into the equation and solve for y to obtain the corresponding y-value.
For x=1: y = 14(1) + 8 = 14 + 8 = 22. The ordered pair is (1, 22).
For x=2: y = 14(2) + 8 = 28 + 8 = 36. The ordered pair is (2, 36).
For x=3: y = 14(3) + 8 = 42 + 8 = 50. The ordered pair is (3, 50).
For x=4: y = 14(4) + 8 = 56 + 8 = 64. The ordered pair is (4, 64).
These ordered pairs represent solutions for the given linear equation and show the dependence of y on x.

How many points need to be removed from this graph so that it will be a function?
Answers
Answer:
The correct option is 3.
Step-by-step explanation:
From the given graph it is noticed that the coordinates of all the points are (-3,2), (-3,3), (1,4), (1,-4), (2,-2), (2,-4).
So, the graph represents a relation,
R = {(-3,2), (-3,3), (1,4), (1,-4), (2,-2), (2,-4)}
A relation is called a function if an only if for each value of x there exist a unique value of y.
In the given relation, for each value of x we have two values of y. So it is not a function. We need to remove any of ordered pairs that have same input values.
From (-3,2) and (-3,3), we need to remove one point.
From (1,4) and (1,-4), we need to remove one point.
From (2,-2) and (2,-4), we need to remove one point.
It means total we need to remove 3 points from this graph so that it will be a function.
Therefore the correct option is 3.

Brian has reduced his cholesterol level by 12% by following a strict diet and regular exercise. If his original level was 220, what is his approximate cholesterol level now?
Answers
Final answer:
By reducing his cholesterol level by 12% from the original 220 mg/dL, Brian's current approximate cholesterol level is 193.6 mg/dL.
Explanation:
Brian has reduced his cholesterol level by 12% by following a strict diet and regular exercise. If his original level was 220, to calculate his current cholesterol level, we need to find 12% of 220 and then subtract that from 220. Here's how:
Calculate 12% of 220: (12/100) * 220 = 26.4.
Subtract the reduction from the original level: 220 - 26.4 = 193.6.
Therefore, Brian's approximate cholesterol level now is 193.6 mg/dL.

given that 4,12,x,y,324,972 is a geometric sequence. find the sum of x and y
Answers
The sum of x and y in the given geometric sequence is 144, with x being 36 and y being 108, based on the common ratio of 3.
To solve the problem, we first need to recognize that a geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a constant called the common ratio. We are given a sequence 4, 12, x, y, 324, 972, and we need to find the common ratio and subsequently x and y.
Step-by-Step Solution:
Find the common ratio (r) using two known consecutive terms.
Once r is found, apply it to determine the missing terms x and y.
Calculate the sum of x and y.
Given the sequence 4, 12, x, y, 324, 972, let's use the first two terms to find the common ratio. The ratio of the second term to the first term is 12 / 4 = 3. Thus, the common ratio (r) = 3.
Now, let's find x by multiplying the second term (12) by the common ratio: x = 12 x 3 = 36.
To find y, multiply x by the common ratio: y = 36 x 3 = 108.
The sum of x and y is then: x + y = 36 + 108 = 144.

There are two containers of milk. There is twice as much milk in the first container as in the second. After using 2 gal. of milk from the second container and 3 gal. of milk from the first container, the second container had 4.5 times less milk than the first. How many gallons of milk were in both containers originally?
Answers
Let us say that:
V1 = initial gallons in first container
V2 = initial gallons in second container
From the problem statement, we can create the equations:
V1 = 2 V2
V1 – 3 = 4.5 (V2 – 2)
Combining the two:
2 V2 – 3 = 4.5 (V2 – 2)
2 V2 – 3 = 4.5 V2 – 9
2.5 V2 = 6
V2 = 2.4 gallons
V1 = 2 V2 = 4.8 gallons
So there are 4.8 gallons in the 1st container while 2.4 gallons in the 2nd container.

A cone has a diameter of 18 units and height of 8 units. What is its volume?
Answers
Answer:
289
Step-by-step explanation:
btw i need the point pls dont use this
Final answer:
The volume of a cone with a diameter of 18 units and height of 8 units is approximately 678.58 cubic units, calculated using the formula V = 1/3πr²h.
Explanation:
The student is asking about the volume of a cone with a given diameter and height. To calculate the volume (V) of a cone, you can use the formula:
V = ⅓πr²h
where π (pi) is approximately 3.14159, r is the radius of the base of the cone, and h is the height of the cone.
The diameter is given as 18 units, so the radius (r) is half of the diameter, which is 9 units. The height (h) is given as 8 units. By substituting these values into the formula, the calculation for the volume is:
V = ⅓π(9 units)²(8 units)
V = ⅓π(81 units²)(8 units)
V = ⅓π(648 units³)
V = 216π units³
When we calculate this using the approximate value of π, the volume is:
V = 216 × 3.14159 units³
V = 678.58464 units³
The volume of the cone is approximately 678.58 cubic units.
‘Mathnificent’ is a math tutoring service. The first year it was open, it had 5 students. If 3 new students enroll each year, which of the following equations represents how many students will be enrolled in x years?
A. y = 5x - 3
B. y = 5x + 3y
C. y = 3x - 5
D. y = 3x + 5
Answers
Final answer:
The equation representing the number of students enrolled after x years is y = 3x + 5, taking into account the initial number of students and the annual enrollment of new students.(Option D)
Explanation:
To determine the equation that represents the number of students enrolled in Mathnificent tutoring service in x years, we start with the initial condition that there were 5 students in the first year. Since 3 new students enroll each year, we add 3 to the number of students for each subsequent year. The total number of students after x years can be represented by adding the product of 3 (the number of new students enrolling each year) and x (the number of years) to the initial number of students, which is 5.
The correct equation to represent this scenario is y = 3x + 5. This equation indicates that there is a constant rate of new students enrolling each year (3), and we are adding these to the initial count (5).
