15. The volumes of two similar solids are 857.5 mm^3 and 540 mm^3. The surface area of the smaller solid is 108 mm^2. What is the surface area of the larger solid?
The required surface area of the larger solid is approximately 147 mm². Option A is correct.
We know that,
The surface area of any form is the area of the shape that is fronted.
The surface area of a 3D object is the amount of area covering the outside.
Let's say the surface area of the bigger solid S.
Since the two solids are similar, their volumes have a ratio of (side length)³.
Let's say the ratio of the side lengths of the larger to the smaller solid as k. Then,
⇒ k³ (540 mm³) = 857.5 mm³
Simplifying the above equation, we get:
⇒ k = 7/6
So, the larger solid is about 7/6=1.183 times bigger than the smaller solid in terms of side length.
Since the surface area has a ratio of (side length)²,
we can find the surface area of the larger solid by:
⇒ (1.83²)(108 mm³)
≈ 174 mm³
Therefore, the surface area of the larger solid is approximately 147 mm².

The simplified form of the expression 3 1/5x + 10 7/9 - 2 2/5x - 10 8/9 is 4/5x - 1/9.
To simplify the expression: 3 1/5x + 10 7/9 - 2 2/5x - 10 8/9, we need to perform the addition and subtraction of the terms.
First, let's focus on the x terms: 3 1/5x - 2 2/5x.
The whole numbers can be treated as fractions with a denominator of 1. Thus, we have:
(3 1/5)x - (2 2/5)x.
To perform the subtraction, we need to find a common denominator for the fractions involved, which is 5.
(3 1/5)x - (2 2/5)x = (16/5)x - (12/5)x.
Now we can subtract the terms:
(16/5)x - (12/5)x = (16 - 12)/5x.

Given the functions listed,
a) Determine the rule for (f - g)(x)
b) Evaluate (f – g)(-2)
f(x)=2x^2-3x+4 & g(x) = 8x +7
The rule for (f - g)(x) is (f - g)(x) = 2x² - 11x - 3 and the value of (f - g)(-2) is 27
Determining the rule for (f - g)(x)From the question, we have the following parameters that can be used in our computation:
f(x) = 2x² - 3x + 4
g(x) = 8x + 7
The rule for (f - g)(x) is calculated as
(f - g)(x) = f(x) - g(x)
Substitute the known values in the above equation, so, we have the following representation
(f - g)(x) = 2x² - 3x + 4 - 8x - 7
So, we have
(f - g)(x) = 2x² - 11x - 3
Evaluating the function (f - g)(-2)Here, we have
x = -2
Substitute the known values in the (f - g)(x) = 2x² - 11x - 3, so, we have the following representation
(f - g)(-2) = 2(-2)² - 11(-2) - 3
Evaluate
(f - g)(-2) = 27
Hence, the value of (f - g)(-2) is 27

Jace kicked a soccer ball at a speed of 40 feet per second. If the ball never leaves the ground, then it can be represented by the function H(t) = −16t2 + 40t. Determine the time the ball traveled. (1 point)
t = 0.4 seconds
t = 2.5 seconds
t = 24 seconds
t = 40 seconds
The time that the ball traveled is given as follows:
t = 2.5 seconds.
How to obtain the time that the ball traveled?The quadratic function modeling the ball's height after t seconds is given as follows:
H(t) = -16t² + 40t.
To obtain the time traveled by the height, we must obtain the roots of the quadratic function, as follows:
-16t² + 40t = 0.
16t² - 40t = 0
t(16t - 40) = 0.
Hence the roots are:
t = 0.16t - 40 = 0 -> t = 40/16 -> t = 2.5.Which means that the time traveled by the ball is given as follows:
2.5 - 0 = 2.5 seconds.

The maximum error of the midpoint approximation is 0.55.
How to find the maximum error of the midpointTo estimate the maximum error, we can consider the worst-case scenario by assuming that the second derivative is at its maximum value throughout the interval [11, 31]. In this case, we can use the largest possible value for M.
To find the maximum error of the midpoint approximation, we need to determine the width of the interval and divide it by 2.
Width of the interval = upper bound - lower bound = 10.5 - 9.4 = 1.1
Maximum error (E) = (Width of the interval) / 2 = 1.1 / 2 = 0.55
Therefore, the maximum error of the midpoint approximation is 0.55.

A picture framing business designs two types
of pictures -- matted and unmatted.
The company employees can complete 36
pictures each day using up to 80 total man-
hours of labor. It takes 4 man-hours to complete
one matted and framed picture, and 2 man-hours
to complete one unmatted and framed picture.
How many of each type of picture should be
made daily to maximize the company's profit,
if the profit on a matted picture is $40 and the
profit on an unmatted picture is $35?
To determine the optimal number of matted and unmatted pictures to maximize the company's profit, we can set up a linear programming problem.
Let's denote:
- x: the number of matted pictures
- y: the number of unmatted pictures
The objective is to maximize the profit, which can be expressed as:
Profit = 40x + 35y
We need to consider the following constraints:
1) The number of pictures completed each day cannot exceed 36:
x + y ≤ 36
2) The total man-hours of labor cannot exceed 80:
4x + 2y ≤ 80
3) The number of pictures cannot be negative:
x, y ≥ 0
Now we can solve this linear programming problem to find the optimal values for x and y.
First, let's graph the feasible region defined by the constraints:
```
x + y ≤ 36
4x + 2y ≤ 80
x, y ≥ 0
```
The feasible region is the area of the graph that satisfies all the constraints.
Next, we need to evaluate the objective function (Profit = 40x + 35y) at the vertices of the feasible region to find the maximum profit.
We can use different methods such as the corner-point method or the simplex method to determine the vertices and evaluate the profit at each vertex.
Thus, once we find the vertex that yields the maximum profit, we will have the optimal values for x and y.

A rectangles width is 1/2 of its length. Its area is 338 square centimeters. What are its dimensions?
The width of the rectangle is 13 cm and the dimension is 26 cm x 13 cm
Given data ,
Let the length be L and width be W
Now , the width is 1/2 of the length, so we can write:
W = (1/2)L
The area of a rectangle is given by the formula:
Area = Length x Width
Given that the area is 338 square centimeters, we can write:
338 = L × W
Substituting W with (1/2)L, we have:
338 = L × (1/2)L
To solve this equation, we can multiply both sides by 2 to eliminate the fraction:
676 = L²
Taking the square root of both sides, we find:
L = √676
L = 26
So the length of the rectangle is 26 centimeters.
Substituting this value back into the equation for the width, we have:
W = (1/2)L
W = (1/2)(26)
W = 13
Hence , the dimensions of the rectangle are length = 26 centimeters and width = 13 centimeters

Combine like terms:
[tex]1/5y + 2 - 4/5 = 1/2y - 1 + 1/10y[/tex]
Simplify the equation by getting rid of fractions. To do this, we can multiply every term by the least common denominator (LCD) of 10:
[tex]10 * (1/5y + 6/5) = 10 * (3/5y - 1 + 1/10y)[/tex]
Simplifying further:
[tex]2y + 12 = 6y - 10 + y[/tex]
Now, let's combine like terms again:
[tex]2y + 12 = 7y - 10[/tex]
Next, let's isolate the variable y. Subtract 2y from both sides and add 10 to both sides:
[tex]12 + 10 = 7y - 2y[/tex]
Simplifying:
22 = 5y
Finally, divide both sides by 5 to solve for y:
