The estimated cost for one student to purchase the ingredients for s'mores at the camp store is $2.10.
To estimate the cost for one student, we can divide the total cost for 15 students by the number of students. Given that the ingredients cost $31.50 for 15 students, we can calculate the cost for one student as follows:
Cost for 1 student = Total cost for 15 students / Number of students
Cost for 1 student = $31.50 / 15
Cost for 1 student ≈ $2.10
Therefore, the estimated cost for one student to purchase the ingredients for s'mores at the camp store is approximately $2.10. This calculation assumes that the cost is evenly distributed among the students and that the quantity of ingredients per student remains constant.

3 = x+3 – 5x how can I solve this using a multi step equation
Answer: x = 0
Step-by-step explanation:
Given equation (swapped position):
x + 3 - 5x = 3
Combine like terms:
(x - 5x) + 3 = 3
-4x + 3 = 3
Subtract 3 on both sides:
-4x + 3 - 3 = 3 - 3
-4x = 0
Divide -4 on both sides:
-4x / -4 = 0 / -4

The size of a computer monitor is usually given by the length of its diagonal. A monitor's aspect ratio is the ratio of its width to its height. This monitor has a diagonal length of 27 inches and an aspect ratio of 16:9. Using ratios and the Pythagorean Theorem the approximate width is 23.5 inches and the height is inches.
The length and width of the computer monitor is 23.36 inches
and 13.14 inches.
According to the given statement
we have given that
The length of diagonal of rectangular monitor = 27 inches
The length to width ratio is 16:9
So , Let the Length of monitor = 16x
and The Width of monitor = 9x
And we have to find the length and width of the computer monitor.
So, For this purpose,
From Pythagoras theorem
(Diagonal)² = Length² + width²
Put the values in it and then
27² = (16x)² + (9x)²
729 = 256x² + 81x²
After solving we get
337x² = 729
So, x² = 2.16
∴ x = = 1.46 inches
So, The length = 16x = 23.36 inches
And The width = 9x = 13.14 inches.
Hence, The length and width of the computer monitor is 23.36 inches
and 13.14 inches.

If 2x + 3y = 194 and x = 28, what is the value of y?
Answer:
46
Step-by-step explanation:
For the value of y, substitute x = 28 into the equation.
2x + 3y = 194
2(28) + 3(y) = 194
56 + 3y = 194
3y = 194 - 56
3y = 138
dividing bothsides by 3
y = 46
Answer:
y = 46
Step-by-step explanation:
We want to find the value of y
2x+3y = 194
We are given the value of x
x=28
Substitute the value of x into the first equation
2(28)+3y = 194
56 + 3y = 194
Subtract 56 from each side
56+3y -56 = 194 -56
3y = 138
Divide each side by 3
3y/3 = 138/3
y =46

Solve the system of equations 2x-2y=-14 and 3x-y=-1 by combining the equations.
Combining the equations, the solution to the system of equations is: x = 3, y = 10.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the equations are:

What is the approximate area of the triangle below?
95 degrees 35 degrees 14cm.
By utilizing the law of the sines and Heron's formula, we find that the approximate area of the triangle is approximately 73.1 square centimeters. (Correct choice: A)
How to calculate the area of a triangle by Heron's formula
Prior to using Heron's formula, we must find the lengths of the missing sides by law of the sines:
A = 180° - 95° - 35°
A = 50°
[tex]b = 14\,cm \times \frac{\sin 35^{\circ}}{\sin 50^{\circ}}[/tex]
b ≈ 10.483 cm
[tex]c = 14\,cm \times \frac{\sin 95^{\circ}}{\sin 50^{\circ}}[/tex]
c ≈ 18.206 cm
Now, we proceed to calculate the area of the triangle:
s = 0.5 · (14 cm + 10.483 cm + 18.206 cm)
s = 21.345 cm
[tex]A = \sqrt{(21.345\, cm) \cdot (21.345\, cm - 14\,cm)\cdot (21.345\, cm - 10.483\,cm)\cdot (21.345\,cm - 18.206\,cm)}[/tex]
A ≈ 73.113 cm²

The measure of each exterior angle of a regular polygon is $30$ degrees. What is the sum of the measures of the interior angles, in degrees
Answer: 1800
Step-by-step explanation:
Exterior angles of a polygon add to 360 degrees, so this means the polygon has 12 sides.
We also know that since an interior angle and its corresponding exterior angle are supplementary, each interior angle is 150 degrees.
Therefore, the sum of the measures of the interior angles is (150)(12)=1800 degrees.

How to difference between parent quadratic equations and resulting quadratic equations
Herein we find the graph of the parent quadratic equation f(x) = x² and two proposed resulting functions, whose difference with the former one have to be explained in terms of the kind of rigid transformations they have.
By comparing them, we find that both functions g(x) and h(x) are the result of a rigid transformation of the form f'(x) = k · f(x), where the transformation is a simple vertical dilation for k > 1, simple vertical contraction for 0 < k < 1, vertical contraction and reflection around the x-axis for - 1 < k < 0 and vertical dilation and reflection around the x-axis for k < - 1.
Function g(x) is the result of dilating f(x) by a factor of 3 and function h(x) is the result of dilating and reflecting f(x) around the x-axis by a factor of - 3.
The tables for each quadratic function are summarized below:

If the mean is 382 and standard deviation is 97 then according to empirical rule 50% students scored between 285 and 479 on the exam.
Given mean of 382 and standard deviation of 97.
We have to calculate the percentage of students scored between 285 and 479 on the exam.
Percentage is a number or ratio that is expressed in terms of 100.
We have to use z statistic in this question.
z=X-μ/σ
where μ is mean and
σ is standard deviation
from 285 to 382
z=285-383/97

p value =0.1587.
From 382 to 479
z=479-382/97

p value =0.3413
Total probability from 285 to 382 is 0.3413+0.1587=0.5
