Suppose you are building a storage box of volume 4368in^3. the length of the box will be 24 in. the height of the box will be 1 in. more than its width. find the height and the width of the box.
Answers
Answer:
height: 14 incheswidth: 13 inchesStep-by-step explanation:
The volume formula can be used to find the height and width of a box with volume 4368 in³ and height 1 in greater than width.
SetupThe volume formula is ...
V = LWH
Substituting given information, using w for the width, we have ...
4368 = (24)(w)(w+1)
SolutionWe want to find the value of w.
182 = w² +w . . . . . . . . divide by 24
182.25 = w² +w +0.25 = (w +0.5)² . . . . . . add 0.25 to complete the square
13.5 = w +0.5 . . . . . . . . take the positive square root
w = 13 . . . . . . . . . . . . subtract 0.5
h = w+1 = 14
The height of the box is 14 inches; the width is 13 inches.
__
Additional comment
By "completing the square", we can arrive at the exact dimensions of the box, as we did above. Note that we only added 0.25 to the equation to do this.
For numbers close together, the geometric mean (root of their product) is about the same as the arithmetic mean (half the sum):
\(\sqrt{w(w+1)}\approx\dfrac{w+(w+1)}{2}=w+\dfrac{1}{2}\\\\w\approx\sqrt{182}-\dfrac{1}{2}\approx12.99\)
Using this approximation to arrive at the conclusion w=13 saves the steps of figuring the value necessary to complete the square, then adding that before taking the root.
answer for 14+3y < 65
Answers
Answer:
The answer is y<17
Step-by-step explanation:
First, move the constant to the right.
3y<65-14
Then, subtract 65 and 14
3y<51
Lastly, divide both sides by 3.
y<17
14 + 3y < 65
SOME people replace “<”, “>”, “≥”, or “≤” as an equal sign (=) to make it easier to solve
14 + 3y < 65
14 + 3y = 65
SUBTRACT by 14 on both of your sides
3y + 14 - 14 = 65 - 14
CANCEL out: 14 - 14 because that gives you 0
KEEP: 65 - 14 because it helps you solve for “y”
**65 - 14 = 51**
NEW EQUATION: 3y = 51
DIVIDE by 3 both of your sides
3y/3 = 51/3
CANCEL out: 3/3 because that gives you 1
KEEP: 51/3 because it gives you the value of “y”
NEW EQUATION: y = 51/3
**51/3 = 17**

One endpoint of a line segment is (10,-1). The point (7,-2) i s one-third of the way from that endpoint to the other endpoint. Find the other endpoint
Answers
The coordinates of the other endpoint of the Line segment is (-2,-5).
If M(x.y) divides the line formed by two points A(a,b) and B(c,d) into a ratio m:n. Then the coordinates of the point M can be found out by using the formula,
x = (mc + na)/(m+n)
y = (md + nb)/(m+n)
This above mentioned formula is known as The section Formula.
The one of the End point of the line is (10,-1) and the point (7,-2) is dividing the line in the ratio of 1:3.
Let us assume the other end point to be (a,b).
Now, applying Section Formula,
7 = [(1)(a)+(3)(10)]/4 and
-2 = [(1)(b)+(3)(-1)]/4
Further solving,
a = -2 and

Answers
Answer:
(5,9)
(-19, - 15)

Step-by-step explanation:
Given that :
Coordinate of point A = - 7, - 3
Number of points between point A and B = 12
Possible coordinate of point B
Possible coordinates of point B:
(-7, - 3) + 12 = (5, 9)
(-7, - 3) - 12 = (-19, - 15)
(-7, - 3) = (-7 +12, -3 - 12) = (5, - 15)
(-7, - 3) = (-7 - 12, - 3 + 12) = (-19, 9)
Hence possible coordinates of be are :

3*7*13*11=1001*3=3003
Feel free to tell me if I did anything wrong! :)
The basketball team has 3,003,600 possible starting lineups. Given that there are 15 players on the roster and 5 players on the basketball court, this calculation involves determining the number of ways to select 5 players out of the total 15.
To calculate the number of possible starting lineups, we can use the concept of combinations. We have 15 players on the roster, and we need to select 5 players to form a starting lineup.
The number of ways to choose 5 players out of 15 can be calculated using the combination formula:
C(n, r) = n! / (r! * (n - r)!)
In this case, n represents the total number of players (15) and r represents the number of players needed for the lineup (5).
Plugging these values into the formula, we get:
C(15, 5) = 15! / (5! * (15 - 5)!)
= (15 * 14 * 13 * 12 * 11 * 10!) / (5! * 10!)
= (15 * 14 * 13 * 12 * 11) / (5 * 4 * 3 * 2 * 1)
= 3,003,600
Therefore, there are 3,003,600 possible starting lineups for the basketball team. This means that the team has a vast number of combinations to choose from when selecting the starting lineup from the 15 players on its roster.

* Let D and T be sets, and let X:D→T be a function from D to T. Let T be a σ-algebra of subsets of T, and define D={X−1(B):B∈T}, the collection of subsets A⊂D of the form A=X−1(B) for B∈T. (a) ∗ Show directly that D is a σ-algebra of subsets of D. [3 marks] Now let T=R and T=B, the Borel σ-algebra. Let Ω=D, let F be a σ-algebra of subsets of Ω, and let P be a probability measure on (Ω,F). (a) * Suppose that X is a random variable on the probability space (Ω,F,P). Show that D⊂F.
Answers
The set D, defined as D = {X^(-1)(B) : B ∈ T}, is a σ-algebra of subsets of D. If X is a random variable on a probability space (Ω, F, P), then D is a subset of the σ-algebra F.
To show that D is a σ-algebra of subsets of D, we need to verify three conditions:
1. D is non-empty: Since X is a function from D to T, the pre-image of the entire space T is D itself, so D is non-empty.
2. D is closed under complementation: For any set A ∈ D, there exists a corresponding set B ∈ T such that A = X^(-1)(B). Taking the complement of A, we have A^c = X^(-1)(B^c), where B^c is the complement of B in T. Since T is a σ-algebra, B^c ∈ T, and therefore A^c ∈ D.
3. D is closed under countable unions: Let {A_n} be a countable collection of sets in D, with corresponding sets {B_n} in T such that A_n = X^(-1)(B_n) for each n. Taking the union of all the A_n's, we have ∪A_n = X^(-1)(∪B_n), where ∪B_n is the union of all the B_n's in T. Since T is a σ-algebra, ∪B_n ∈ T, and therefore ∪A_n ∈ D.
Now, if X is a random variable on the probability space (Ω, F, P), it means that X is measurable with respect to the σ-algebra F. Since D is a σ-algebra of subsets of D, and X^(-1)(B) ∈ D for any B ∈ T, we can conclude that D ⊂ F.
Therefore, D is a subset of the σ-algebra F when X is a random variable on the probability space (Ω, F, P).

Let's calculate the mean of Becca's first eight:
Mean = sum of items/# of items
(10 + 10 + 15 + 15 + 18 + 20 + 20 + 20)/8 = 16

(10 + 10 + 15 + 15 + 18 + 20 + 20 + 20 + 25)/8 = 19 1/8 or 19.125

A = 4*4 = 16
A = area
l = length
l = 4
w = width
w = 4
The area is equal to 16.
P = 2*4 + 2*4 = 16
P = perimeter
2l = 2*length
2l = 2*4
2w = 2*width
2w = 2*4
The perimeter is equal to 16.

john has walked 15% of the way home from school. if he has walked 54 yards so far, how far does he walk home from school
Answers
Answer: John walks a total of 360 yards from school.
Step-by-step explanation:
Let's represent the total distance John walks from school as "x".
According to the problem, John has already walked 15% of the way, which can be written as:
0.15x
We also know that he has walked 54 yards so far, which means:
0.15x = 54
To find the total distance John walks from school, we can solve for "x" by dividing both sides of the equation by 0.15:
x = 54 ÷ 0.15
x = 360
Therefore, John walks a total of 360 yards from school.
