Joseph's bedroom is 7 feet long
and 8 feet wide. His brother's
room is 10 feet long and 5 feet
wide. Whose bedroom has the
largest area? |
Joseph will have a room with the larger area than his brother.
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The space enclosed by the boundary of a plane figure is called its area.
The area of a figure is the number of unit squares that cover the surface of a closed figure.
Area is measured in square units like cm² and m².
Given that, Joseph's bedroom is 7 feet long and 8 feet wide. His brother's room is 10 feet long and 5 feet wide.
We need to find that whose bedroom has the larger area.
The area will be given by = length x width
So,
Joseph's room area = 7 x 8 = 56 sq ft
Brother's room area = 10 x 5 = 50 sq ft
Since, 50 < 56
Hence, Joseph will have a room with the larger area than his brother.

four pumpkins weigh 26 pounds altogether. Pumkin one weighs four less than three times the weight of Pumkin threee. Pumkin four weighs twice as much as pumkin One. Pumpkin Two weighs five more pounds than Pumkin three. What does each pumpkin weigh
Answer:
5, 8, 3, 10 lbs.
Step-by-step explanation:
We can solve this using a system of equations! We will call pumpkins \(a, b, c, d\).
Our equations are thus:
\(a + b + c + d = 26\)
\(a = 3c - 4\)
\(d = 2a\)
\(b = c + 5\)
So now we just need to solve this system of equations.
We can start by solving for the value of pumpkin \(c\) and go from there. So first we substitute some equations around.
First we write out pumpkin \(d\) in terms of \(a\).
\(d = 2a = 2(3c - 4) = 6c - 8\)
And now we put the three equations into the first equation:
\(a + b + c + d = 26\\(3c-4)+(c+5)+(c)+(6c-8)=26\)
Then we simplify to get:
\(11 c - 7 = 26\)
\(11c = 33\\c = 3\)
So we know pumpkin \(c\) weighs 3 pounds.
Then we use the equations from before to get the value of the other pumpkins:
\(a = 3c-4 = (3*3)-4=9-4=5\\d = 2a = 2*5=10\\b = c + 5 = 3 + 5 = 8\)
And we can check our results by putting into first equation:
\(5+8+3+10=26\)
So it works out!
Thus our pumpkins weigh 5, 8, 3, 10 lbs each.
A sample of 2,000 was sought to estimate the average achievement in science of fifth graders in a city’s public schools. The average fifth grade enrollment in the city’s elementary schools is 100 students. Thus, 20 schools were randomly selected and within each of those schools all fifth graders were tested. What sampling technique was used?
Answer:
"Clustering sampling" is the correct answer.
Step-by-step explanation:
If our entire demographic has been separated into segments or groupings, people employ clustering sampling. Those same groupings constitute diverse structurally and therefore are necessarily the same thing uniform.Researchers choose certain of the globular groupings, which are taken throughout the sampling one for each of the specified cluster centers.if x^x=4^(x+16), find x
The value of x in the equation x^x = 4^(x + 16) is 16
How to determine the value of xFrom the question, we have the following parameters that can be used in our computation:
x^x = 4^(x + 16)
Take the logarithm of both sides
So, we have
xlog(x) = (x + 16)log(4)
At this point, we make use of a graphing calculator
From the calculator, we have
x = 16
Hence, the solution is x = 16

Find the angle marked x in each of these polygons
The angles marked x in each of the polygons are 128° and 82° respectively.
What are Concave Polygons?Concave polygons are closed two dimensional figures whose at least one of the interior angle is more than 180 degrees.
The given polygons are named as ABCDEFGH and PQRSTU as shown below.
1) An interior angle and a corresponding exterior angles are supplementary.
Interior angle ∠B = 180° - 42° = 138°
Similarly,
Interior angle, ∠E = 180° - 34° = 146°
Also, angle around a point = 360°
Interior angle at G = 360° - 141° = 219°
Sum of the angles of a polygon = (n - 2) 180°, where n is the number of sides.
Here, number of sides, n = 8
x + 138° + 107° + 145° + 146° + 126° + 219° + 71° = (8 - 2) 180°
x + 952° = 1080
x = 1080 - 952
x = 128°
2) The dotted line implies that the shape is symmetrical.
∠Q = ∠U and ∠R = ∠T
∠Q = ∠U = 34°
Exterior angle at T = 87°
Interior angle at T = 360° - 87° = 273°
So ∠R = ∠T = 273°
Again number of sides, n = 6
x + 34 + 273 + 24 + 273 + 34 = (6 - 2) 180
x + 638 = 720
x = 720 - 638 = 82°
Hence the angle are 128° and 82°.

You want to restrict the domain of the function shown in the graph below to make it one-to-one so that it will have an inverse. What are the largest domains, in interval notation you could use
Answer:
(-∞, -3] or [-3, ∞)
Step-by-step explanation:
You want the largest domain interval(s) on which the function shown in the graph could be one-to-one.
One-to-oneA one-to-one function must pass the horizontal line test. That is, no horizontal line can intersect its graph in more than one place.
ApplicationFor that to be true of the given function, the interval on which it is defined cannot include values on both sides of x=-3, where the graph has a minimum. That is, the domain must be either x ≤ -3, or x ≥ -3, (or some subset of either of these).
The largest intervals on which the function has an inverse are ...
(-∞, -3] or [-3, ∞)
<95141404393>
To make the given function one-to-one and have an inverse, we can restrict its domain to (-∞, a) or (a, ∞), where 'a' is the x-coordinate of the highest or lowest point on the graph.
Explanation:To make the given function one-to-one and have an inverse, we need to restrict its domain. The largest domains, in interval notation, that can be used are: (-∞, a) or (a, ∞) where 'a' is the x-coordinate of the highest or the lowest point on the graph, depending on the function type.
If the graph has a highest point, the domain is restricted to (a, ∞), where 'a' is the x-coordinate of the highest point. If the graph has a lowest point, the domain is restricted to (-∞, a), where 'a' is the x-coordinate of the lowest point.
For example, if the graph has a highest point at (3, 5), the domain would be restricted to (3, ∞) to make the function one-to-one and have an inverse.

B)
x = 49
C)
x = 15
D)
x = 21
Solution of the inequality x/5 + 2 ≤ 6 is x ≤ 20, so x = 15 is a solution.
Correct option is C.
What is inequality?An inequality is a mathematical expression in which both sides are not equal. In an inequality, unlike an equation, two values are compared. The equal sign between two numbers is replaced by a less than (or less than or equal to), greater than (or greater than or equal to) sign, or not equal to.
Given inequality
x/5 + 2 ≤ 6
taking LCM on left side
(x + 10)/5 ≤ 6
Multiplying by 5 on both sides
x + 10 ≤ 30
Subtracting 10 from both sides
x ≤ 30 - 10
x ≤ 20
x = 37 ; 37 > 20, it is not solution of inequality
x = 49 ; 49 > 20, it is not solution of inequality
x = 15 ; 15 < 20, it is a solution of inequality

___________________________________________________I AM ALWAYS HAPPY TO HELP :)(a) From Latoya's results, compute the experimental probability of rolling a 1 or 6.
(b)Assuming that the cube is fair, compute the theoretical probability of rolling a 1 or 6.
(c)Assuming that the cube is fair, choose the statement below that is true.
A. The experimental and theoretical probabilities must always be equal.
B. As the number of rolls increases, we expect the experimental and theoretical probabilities to
become closer, though they might not be equal.
C. As the number of rolls increases, we expect the experimental and theoretical probabilities to
become farther apart.
(a) To compute the experimental probability of rolling a 1 or 6 from Latoya's results, we need to determine the number of times a 1 or 6 was rolled and divide it by the total number of rolls Latoya made.
Let's assume that Latoya rolled the dice 100 times and obtained 20 1's and 10 6's. The total number of successful outcomes (rolling a 1 or 6) is 20 + 10 = 30.
Therefore, the experimental probability of rolling a 1 or 6 is 30/100 = 0.3 or 30%.
(b) Assuming the cube is fair, the theoretical probability of rolling a 1 or 6 can be determined by considering the favorable outcomes (rolling a 1 or 6) divided by the total possible outcomes (rolling any number from 1 to 6).
Since there are two favorable outcomes (1 and 6) out of six possible outcomes (1, 2, 3, 4, 5, 6), the theoretical probability is 2/6 = 1/3 or approximately 0.3333.
(c) The correct statement is B. As the number of rolls increases, we expect the experimental and theoretical probabilities to become closer, though they might not be equal. This is due to the law of large numbers, which states that as more trials are conducted, the experimental probability tends to converge towards the theoretical probability. However, it is not necessary for them to be exactly equal. Random variations can cause some discrepancy, but with a larger number of rolls, the experimental probability should approach the theoretical probability more closely.

The value of x in the polygon will be 13.25 degrees.
The value of x is 10.
We can find the value of x by plugging in the number of sides of the regular polygon into the formula x = (n-2)*15° - 1.
How to calculate the valueThe sum of the interior angles of a regular polygon with n sides is (n-2) x 180 degrees.
Sum of angles = (24-2) x 180 = 22 x 180 = 3960 degrees
Since all the angles in a regular polygon are congruent, we can divide the sum of the angles by the number of angles to find the measure of one angle:
Measure of one angle = 3960/24 = 165 degrees
165 = 12x + 6
159 = 12x
x = 13.25
Therefore, the value of x is 13.25 degrees.
Each of the triangles in our decomposition has one angle equal to (17x+2)°, so the sum of all the angles in the triangles is 43 × (17x+2)° = 731x+86°.
Therefore, we have:
731x+86° = 7380°
Solving for x, we get:
731x = 7294°
x = 10
Therefore, the value of x is 10.
The equation that can be used to find the value of x is:
(9x+48)° + (15x-24)° = (n-2)*180°
24x + 24 = (n-2)*180°
Dividing both sides by 24, we get:
x + 1 = (n-2)*15°
Subtracting 1 from both sides, we get:
x = (n-2)*15° - 1

A 6 foot wide painting should be centered on a 10 foot wide wall. Type the left side of an equation that can be used to determine how many feet (x) should be on each side of the painting.
The left side of the equation is (x + 6) + x. The sum of these two quantities should be equal to the total width of the wall, which is 10 feet.
To determine how many feet should be on each side of the painting to center it on a 10-foot wide wall, we can set up an equation. Let's denote the number of feet on each side of the painting as x.
The total width of the wall is 10 feet, and the painting is 6 feet wide. Since we want the painting to be centered, we need an equal amount of space on each side. So, we can subtract the width of the painting from the total width of the wall and divide it by 2:
(x + 6) + x = 10.
In this equation, (x + 6) represents the width of the painting and the additional x represents the space on the other side of the painting.
