A store pays $871 for a gold ring. The store marks up the price by 26%. What is the
amount of the mark-up?
Round your answer to the nearest dollar: $
Submit
Answers
Answer:
$1097.46
Step-by-step explanation:
Assume P is the finall price. The markup of 26% can be written in decimal form as 0.26. This is in additon to the full price paid for the gold ring, so we can add 1.00 to 0.26 to arrive at the factor 1.26. Multiply 1.26 times the store cost of $871 to find the amount after 26% markup:
($871)*(1.26) = $1097.46

identify the equation for the line tangent to the circle x2 y2 = 169 at the point (−5, 12).
Answers
The equation for the line tangent to the circle \(\(x^2 + y^2 = 169\)\) at the point \(\((-5, 12)\)\) is \(\(x + 5y = 13\)\).
To find the equation of the tangent line to the circle at a given point, we need to determine the slope of the tangent line and its point of tangency. The slope of the tangent line is equal to the negative reciprocal of the derivative of the circle's equation with respect to x.
Differentiating the equation \(\(x^2 + y^2 = 169\)\) with respect to x, we get \(\(2x + 2y \frac{{dy}}{{dx}} = 0\)\). Rearranging this equation, we find \(\(\frac{{dy}}{{dx}} = -\frac{{x}}{{y}}\)\).
Substituting the coordinates of the given point (-5, 12) into the derivative, we have \(\(\frac{{dy}}{{dx}} = -\frac{{-5}}{{12}} = \frac{{5}}{{12}}\)\).
Since the tangent line has the same slope as the derivative at the point of tangency, the slope of the tangent line is \(\(\frac{{5}}{{12}}\)\).
Using the point-slope form of a line, \(\(y - y_1 = m(x - x_1)\)\), where \(\((x_1, y_1)\)\) is the given point, we substitute \(\((-5, 12)\)\) and the slope \(\(\frac{{5}}{{12}}\)\) to obtain \(\(y - 12 = \frac{{5}}{{12}}(x + 5)\)\).
Simplifying this equation, we get \(\(x + 5y = 13\)\), which is the equation of the tangent line to the circle at the point \(\((-5, 12)\)\).

Answers
Jayden needs no fewer than 90 tiles to cover the entire floor of his bathroom during the renovation. This means that he needs at least 90 tiles to complete the project.
It is important for Jayden to accurately measure the size of his bathroom floor and calculate the number of tiles he will need to ensure that he has enough to cover the entire area. If he does not have enough tiles, he may need to purchase additional tiles to complete the project. It is also important for Jayden to consider the size and shape of the tiles he will be using, as this will impact the number of tiles he will need to cover the floor. By accurately measuring and calculating the number of tiles needed, Jayden can ensure that he has enough materials to complete the renovation of his bathroom floor.

What is the value of (−15)3 when evaluated? 3,375 45 −225 −3,375
Answers
The value of the exponential form (-15)³ is -3375.
The f(x)= exp (x) or eˣ are used to represent the exponential function in mathematics (where the argument x is written as an exponent).
The term typically refers to the positive-valued function of a real variable, unless otherwise specified, though it can also be extended to the complex numbers or modified to refer to other mathematical objects like matrices or Lie algebras. The exponential function originated from the concept of exponentiation, or repeated multiplication; but, more recent definitions—of which there are many that are equivalent—allow it to be rigorously extended to all real arguments, including irrational values.We know that any exponential form such as (-15)³ can be written as
-15×-15×-15 = -3375
Therefore the solution of the exponential form is -3375 .

You polled 2805 Americans and asked them if they drink tea daily. 724 said yes. With a 95% confidence level, construct a confidence interval of the proportion of Americans who drink tea daily. Specify the margin of error and the confidence interval in your answer.
Answers
According to the information, the 95% confidence interval for the proportion of Americans who drink tea daily is approximately (0.2485, 0.2766). The margin of error is approximately 0.0140.
How to construct a confidence interval?To construct a confidence interval for the proportion of Americans who drink tea daily, we can use the formula:
Confidence Interval = p ± Z * \(\sqrt\)((p * (1 - p)) / n)Where,
p = the sample proportion
Z = the critical value corresponding to the desired confidence level
n = the sample size
Given:
Sample size (n) = 2805Number of Americans who drink tea daily (p) = 724/2805 ≈ 0.2580 (rounded to four decimal places)Z-value for a 95% confidence level ≈ 1.96Now, let's calculate the confidence interval and margin of error:
Confidence Interval = 0.2580 ± 1.96 * \(\sqrt\)((0.2580 * (1 - 0.2580)) / 2805)Confidence Interval ≈ (0.2485, 0.2766)Margin of Error = 1.96 * \(\sqrt\)((0.2580 * (1 - 0.2580)) / 2805)Margin of Error ≈ 0.0140According to the information, the 95% confidence interval for the proportion of Americans who drink tea daily is approximately (0.2485, 0.2766), with a margin of error of approximately 0.0140.

A window manufacturer claims that the seals break on only 4% of its windows. What is the probability that, in a sample of 10 windows, no seals will break?
Answers
Answer:
0.96
Step-by-step explanation:
Total samples of window = 10smaples
Total seal break = 4% of 10
Total seal break = 0.04 * 10
Total seal break = 0.4
THis means that no seal will be break on 96% of the window i.e 9.6 windows
The probability that, in a sample of 10 windows, no seals will break is expressed
as;
Pr(no seal will break) = 9.6/10
Pr(no seal will break) = 0.96
Hence the probability that no seals will break is 0.96

A. setg 47 23: This option is incorrect because setg is used to set a byte to 1 if the Greater flag (ZF=0 and SF=OF) is set, but the given values of a and b are 47 and 23, respectively, so it does not satisfy the condition for setg to be set.
B. setl 23 47: This option is incorrect because setl is used to set a byte to 1 if the Less flag (SF≠OF) is set, but the given values of a and b are 23 and 47, respectively, so it does not satisfy the condition for setl to be set.
C. sete 23 23: This option is incorrect because sete is used to set a byte to 1 if the Zero flag (ZF=1) is set, but the given values of a and b are 23 and 23, respectively, so it does not satisfy the condition for sete to be set.
D. setne 23 47: This option is correct. setne is used to set a byte to 1 if the Zero flag (ZF=0) is not set, which means the values of a and b are not equal. In this case, the given values of a and b are 23 and 47, respectively, so they are not equal, and setne should be used.

There will be a fence around the garden. The fencing costs $8.25 per linear foot. About how much will the fencing cost altogether?

Then, the fencing cost will be:

What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
We have been given the expression:
12(p + 5) − 11(3q + 4)
Apply the distributive property of multiplication,
12p + 12 × 5 − 11 × 3q + 11 × 4
12p + 60 - 33q + 44
Rearrange the terms likewise and apply the arithmetic operation,
12p - 33q + 60 + 44
12p - 33q + 104
Therefore, required expression would be 12p - 33q + 104 which is equivalent form of 12(p + 5) − 11(3q + 4).

What is a dilation?In Mathematics and Geometry, a dilation simply refers to a type of transformation which typically changes the size of a geometric object, but not its shape.
This ultimately implies that, the size of the geometric shape would be increased (stretched or enlarged) or decreased (compressed or reduced) based on the scale factor applied.
Next, we would apply a dilation to the coordinates of the pre-image by using a scale factor of 4 centered at the origin as follows:
Ordered pair R (1, 3) → Ordered pair R' (1 × 4, 3 × 4) = R' (4, 12).
Ordered pair S (3, 3) → Ordered pair S' (3 × 4, 3 × 4) = S' (12, 12).
