The answer is $112.70 The Question is a simple Sales tax rate calculating problem.
How do you solve sales tax problems?Multiplying the purchase price by the sales tax rate will provide the sales tax. Don't forget to round the sales tax rate from percent to decimal. The price of the purchase is increased after the sales tax has been calculated. The entire cost is what the client pays as a result.
Sales tax rate = Sales tax percent / 100.
Sales tax = List price x Sales tax rate.
Given,
Rate of sandwich is = $4. 00
Rate of drink is = 94$
The rate of a meal that Her grandson ordered is =$6. 35.
What was the total price of all three items when 8% sales tax was added?
Total price of all three items without tax = 4 + 94 + 6.35
= $104.35
Total price of all three items with tax = (100% + tax) * Price
= (100% + 8%) * 104.35 = 108% * 104.35
= 1.08 * 104.35 = 112.698
≅ $112.70
The estimation to check if the result is reasonable by putting the answer in the original equation.
E.g. x + 4 = 10; x = 10 - 4
We get that x = 6
Plug in x = 6 in x + 4 = 10.
6 + 4 = 10.

What is the coefficient of y2 in the expression 2x2y 15xy2 7y?
Let x be the coefficient of y^2 in the expression 2x^2y+15xy^2-7y. So x=0.
What is co-efficient?
A coefficient is a multiplicative factor in a polynomial, series, or expression in mathematics. It is typically a number, although it can also be any expression (including variables such as a, b and c). They may also be referred to as parameters if the coefficients are variables in and of themselves.
Write an example of co-efficient.
As an illustration, 6z stands for 6 times z. Since z is a variable, 6 is a coefficient. For variables without a value, the coefficient is 1.
The given algebraic expression is 2yx^2+15xy^2-7y.
The terms are xy^2, yx^2 any y^2
So the co-efficient of y^2 is 0

Find C using Special right triangles
The length c of the right angle triangle is 9 units.
How to find the side of a right triangle?A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a right angle triangle is 180 degrees.
The sides of a right angle triangle can be found using trigonometric ratios as follows:
Therefore,
sin 60° = opposite / hypotenuse
where
opposite side = c
hypotenuse side = 6√3 ft
Hence,
sin 60° = c / 6 √3
cross multiply
c = 6√3 × sin 60
c = 6√3 × √3 / 2
c = 6 × 3 / 2
c = 18 / 2
Therefore,
c = 9 units

Nevaeh earned a score of 850 on Exam A that had a mean of 550 and a standard deviation of 100. She is about to take Exam B that has a mean of 36 and a standard deviation of 10. How well must Nevaeh score on Exam B in order to do equivalently well as she did on Exam A? Assume that scores on each exam are normally distributed.
Nevaeh's score in Exam A of 850, where the mean and standard deviation are 550, and 100, indicates, using the z-score, that in Exam B with a mean and standard deviation of 36 and 10, respectively, her score should be 66.
What is a z-score?A z-score is an indication of the number of standard deviations, a data point is from the mean.
The score Nevaeh earned in Exam A, x₁ = 850
The mean score for Exam A, μ₁ = 550
The standard deviation for Exam A, σ₁ = 100
The mean score for Exam B, μ₂ = 36
The standard deviation for Exam B, σ₂ = 10
A quantity that can be used to evaluate Nevaeh's score for Exam A is the z-score, which can be expressed as follows;
[tex]z = \dfrac{x - \mu}{\sigma}[/tex]
Nevaeh's z-score for Exam A is therefore;
[tex]z = \dfrac{850 - 550}{100} =3[/tex]
Nevaeh's performance on Exam B in order for her to do equivalently well as she did on Exam A is obtained by using a z-score of 3 for her performance in Exam B as follows;
[tex]z = 3 = \dfrac{x_2 - 36}{10}[/tex]
3 × 10 = x₂ - 36
30 = x₂ - 36
x₂ = 30 + 36 = 66
Nevaeh's score on Exam B should be 66 in order for her to perform equivalently well as she did in Exam A

Answer:

Step-by-step explanation:
The formula for intersecting chords creating which create the limits of arcs and associated angles is
<HES = 1/2 (ARC HS + ARC GF)
<HES = 1/2 (ARC 51 + ARC 195)
<HES = 1/2 (246)
<HES = 123
What that tells you is that <GEF = the same thing because <HES and <GEF are vertically opposite.
Now I am going to assume that <HES = 16x + 11. This is not a sure thing, but I assume it is what is intended.
16x + 11 = 123 Subtract 11 from both sides
16x = 123 - 11
16x = 112 Divide by 16
x = 112/16
x = 7
When can parallelism make your algorithms run faster when could it make your algorithms run slower?
When an algorithm necessitates extensive sharing of instantaneous results, parallelism slows it down. Because there are multiple independent parallel processes and the right number of threads, parallelism will speed up an algorithm.
What algorithm is parallelizable?The ones with data dependencies are the most challenging. It will be exceedingly challenging, for instance, if you are dealing with a vector and the input for the computation at point n depends on the output at position n-1.
When this occurs, you must comprehend what the original algorithm is doing and take an alternative approach. For the aforementioned case, it might be a difficulty with digital signal processing including a feedback-containing digital filter. These are challenging to parallelize, but that is not the sole solution. Instead, you might use the filter and signal's fast Fourier transforms, multiply them, and then perform the inverse transform. All of these operations can be partially parallelized.

Step-by-step explanation:
Eden is working on an experiment for her science fair project. She is planting a total of 10 herbs for an herb garden. She is going to plant basil and mint. The basil plants cost $.50 per plant and the mint plants cost $.25 per plant. Eden has a total of $3 to spend on plants because she also has to purchase potting soil and a long planter pot. Write a system of equations and solve either using elimination or substitution.
A system of equations for this problem can be written as:
x + y = 10 (1) equation for the total number of herbs planted
0.50x + 0.25y = 3 (2) equation for the total cost of the herbs
Where x is the number of basil plants and y is the number of mint plants.
Using substitution, we can solve the system of equations.
Solving equation (1) for x, we get x = 10 - y
Substituting this into equation (2) we get:
0.50(10 - y) + 0.25y = 3
5 - 0.50y + 0.25y = 3
5 = 0.75y + 3
0.75y = -2
y = -2/0.75 = -8/3
So, Eden planted -8/3 mint plants, which doesn't make sense, as a fraction of plant are not possible. This implies that either the number of plants or the amount spent are incorrect or something is missing in the problem description.

Two children take turns breaking up a rectangular chocolate bar 6 squares wide by 8 squares long. They may break the bar only along the divisions between the squares. If the bar breaks into several pieces, they keep breaking the pieces up until only the individual squares remain. The player who cannot make a break loses the game. Who will win
The player who goes first will win.
This is because the chocolate bar can be broken up into 6*8=48 squares, and the player who goes first can always ensure that the second player is left with one square on their turn (by breaking the bar into two pieces that leave one square for the second player to take). This means that the second player will always be the one who cannot make a break, and thus loses the game.
Therefore, The player who goes first will win.
