Answer: 1,900 street tacos and 510 Cuban sandwiches.
Explanation:
Alexi=20*80=1,600
Tony = 17*30=510 3x00 = 300 street tacos
1,600 + 300 = 1,900 street tacos and 510 Cuban sandwiches.

Estimate sin pi/3 if sin pi/2 = 1 and sin 0 = 0 and sin pi = 0
To estimate the value of sin pi/3, which is roughly 1.047 or 60 degrees, we can use standard trigonometric values. Since pi/3 is closer to pi/2 than pi, where sin achieves its maximum of 1, the value of sin pi/3 should be closer to 1 than 0. Standard trigonometric values confirm that sin pi/3 = sqrt(3)/2 = 0.866.
Explanation:To estimate sin pi/3, we can make use of some standard values in trigonometry. Pi is roughly 3.14, hence pi/3 is roughly 1.047. The sin function gives a result of 1 at pi/2 (or 90 degrees), 0 at 0, and again 0 at pi (or 180 degrees). Thus, it achieves its maximum at pi/2 and then decreases to 0 at pi. Intuitively, since pi/3 (or 60 degrees) is closer to pi/2 than to pi, the sin value at pi/3 should be closer to 1 than to 0. From the standard trigonometric values, we know that sin pi/3 = sqrt(3)/2 which is roughly 0.866.

Generate a process that would generate random numbers between –1 and 1 for x and y positions of 10000 points and count how many points fall with the circle, then determine an estimated version of π. (see below to generate floating point random numbers. this generation is not needed to describe the process, but to implement the process)
The question is about using the Monte Carlo method to estimate the value of π, by generating random points in a square, counting how many fall inside a unit circle, and finally using this count to calculate π.
Explanation:This question involves the implementation of a famous problem in computational mathematics known as the Monte Carlo method for estimating the value of π:
First, initialize a variable, say 'count', to 0. This variable will keep track of the number of points falling within the circle.Next, carry out a 'for' loop to generate 10000 points. Each point will have x and y coordinates, each a random floating point number between -1 and 1.For each generated point (x, y), calculate the distance from the point to the origin (0,0), which is sqrt(x^2 + y^2). If this distance is less than or equal to 1, it means that the point lies within the unit circle, so increment the 'count' variable by one.After all 10000 points have been generated and tested, 'count' will hold the total number of points lying within the circle. To determine an estimation of π, use the formula 4 * (count / total_number_of_points).This process is based on the mathematical fact that the ratio of the area of a unit circle to the square it is inscribed in is π/4.

what percent of 1600 is 20?
20 is 1.25% of 1600.
(Part / Whole) * 100 = Percentage
20 by 1600:
20 / 1600 = 0.0125.
Multiply the result by 100 to get the percentage:
0.0125 * 100
= 1.25%.
So, 20 is 1.25% of 1600.

solve the following equation for 2 + √4y -3 = 11
Final answer:
To solve the equation 2 + √(4y - 3) = 11 for y, subtract 2 from both sides, square both sides to remove the square root, then solve for y to find that y = 21.
Explanation:
The question asks to solve the equation 2 + √(4y - 3) = 11 for y. To solve for y, follow the steps below:
First, subtract 2 from both sides of the equation to isolate the square root term: √(4y - 3) = 9.
Now, square both sides of the equation to eliminate the square root: (√(4y - 3))^2 = 9^2, which simplifies to 4y - 3 = 81.
Add 3 to both sides of the equation to isolate the term with y: 4y = 84.
Finally, divide both sides by 4 to solve for y: y = 21.
Therefore, the solution to the equation is y = 21.

True or false: the standard deviation is the square root of the variance.
Answer:
True. The standard deviation is indeed the square root of the variance.
Explanation:
The standard deviation measures the dispersion or spread of data points around the mean in a dataset. It quantifies the average distance of data points from the mean. Mathematically, it's the square root of the variance, which is the average of the squared differences between each data point and the mean. By taking the square root, we return to the original scale of the data, making the standard deviation more interpretable. A higher standard deviation indicates greater variability, while a lower standard deviation suggests that the data points are closer to the mean, signifying less variability within the dataset.

Find the equation of the curve that passes through the point 0, 1 6 and whose slope at each point (x, y) is − x 12y .
The equation is [tex]\(x^2 + 12y^2 - 3072 = 0\),[/tex] obtained from integrating [tex]\(12y \, dy = -x \, dx\)[/tex] with the initial condition.
To find the equation of the curve passing through the point (0, 16) with a slope given by [tex]\( \frac{{dy}}{{dx}} = -\frac{x}{12y} \),[/tex] you can use separation of variables.
Given that [tex]\( \frac{{dy}}{{dx}} = -\frac{x}{12y} \)[/tex], we can rewrite it as:
[tex]\[ 12y \, dy = -x \, dx \][/tex]
Now, integrate both sides:
[tex]\[ \int 12y \, dy = \int -x \, dx \]\[ 6y^2 = -\frac{1}{2}x^2 + C \][/tex]
Given that the curve passes through the point (0, 16), substitute these values into the equation:
[tex]\[ 6(16)^2 = -\frac{1}{2}(0)^2 + C \]\[ 6(256) = C \]\[ C = 1536 \][/tex]
Therefore, the equation of the curve is:
[tex]\[ 6y^2 = -\frac{1}{2}x^2 + 1536 \][/tex]
This can also be written in standard form as:
[tex]\[ x^2 + 12y^2 - 3072 = 0 \][/tex]
So, the equation of the curve is [tex]\( x^2 + 12y^2 - 3072 = 0 \).[/tex]
