Answer:
Length could be 14.05 ft and width 3.41 ft.
Step-by-step explanation:
The volume of the sand in the second box = 24 ft^3.
Let its base be x feet wide and y feet long.
Then 2(x + y) < 35.
The volume of sand = 0.5xy ft^3.
So 0.5xy = 24
xy = 48.
x = 48/y
Substituting ih the above inequality:
2(48/y + y) < 35
96/y + 2y < 35
2y^2 - 35y + 96 < 0
Solving 2y^2 - 35y + 96 = 0 gives y = 3.41, 14.09.
So the length could be 14.05 ft and the width 48/14 = 3.41 ft.
The length could be 14.05 ft and the width will be 3.41 ft.
What is volume?The volume of the sand in the second box = 24 ft³.
Let its base be x feet wide and y feet long.
Then 2(x + y) < 35.
The volume of sand = 0.5xy ft^3.
So 0.5xy = 24
xy = 48.
x = 48/y
Substituting the above inequality:
2(48/y + y) < 35
96/y + 2y < 35
2y² - 35y + 96 < 0
Solving 2y² - 35y + 96 = 0 gives y = 3.41, 14.09.
So the length could be 14.05 ft and the width 48/14 = 3.41 ft.

solve for j
PLEASE SHOW WORK IF YOU CAN
Answer:
j = 15
Step-by-step explanation:
The angles shown form a straight line
Angles on a straight line must add up to 180 degrees
Hence, 2j + 32 + 6j - 2 + 30 = 180
( note that we just created an equation that we can use to solve for j )
We now solve for j using the equation we created.
2j + 32 + 6j - 2 + 30 = 180
step 1 combine like terms
2j + 6j = 8j
32 - 2 + 30 = 60
we now have 180 = 8j + 60
step 2 subtract 60 from each side
60 - 60 cancels out
180 - 60 = 120
we now have 120 = 8j
step 3 divide each side by 8
120 / 8 = 15
8j / 8 = j
we're left with j = 15

Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as
Daniel.
Let k be Kevin's age and let d be Daniel's age.
Which system of equations renresents this situation?
Answer:
k - 2 = 4d - 8
d + 1 = 4d - 8
Step-by-step explanation:
Daniel's age = d
Kevin's age = k
Given that, k = d + 3 -------------- (1)
Two years ago, the age of Daniel = d - 2
Two years ago, the age of Kevin = k - 2
Since, two years ago, Kevin was 4 times as old as
Daniel, k - 2 = 4(d - 2)
Opening the bracket,
k - 2 = 4d - 8
Since the value of k is d + 3 (see (1))
d + 3 - 2 = 4d - 8
d + 1 = 4d - 8
(I am just giving the answer cause I LOVE Linear Equation )
1 + 8 = 4d - d
9 = 3d
9/3 = d
3 = d
Therefore, Daniel's present age is 3 and Kevin's present age = 6

The product of two consecutive even integers is 36 less than 18 times their sum. Find the two integers
Answers:
There are two possible outcomes
The integers are 0 and 2The integers are 34 and 36If your teacher wants only positive integers, then go for the second scenario.
=========================================================
Explanation:
x = smaller integer
x+2 = larger integer
We can see that x+2 follows directly after x, so they are consecutive. Also, there's a gap of 2 units between the values. This is due to the phrasing "consecutive even" instead of just "consecutive".
Their product is x(x+2) = x^2+2x
Their sum is x+(x+2) = 2x+2
The product is 36 less than 18 times their sum, which means,
product = 18*(sum) - 36
x^2+2x = 18(2x+2) - 36
x^2+2x = 36x+36-36
x^2+2x = 36x
x^2+2x-36x = 0
x^2-34x = 0
x(x-34) = 0
x = 0 or x-34 = 0
x = 0 or x = 34
-------------------------------------------
If x = 0, then x+2 = 0+2 = 2
The product is x*(x+2) = 0*2 = 0
The sum is x+(x+2) = 0+2 = 2
If we multiply the sum by 18, then we get 18*2 = 36. Subtracting off 36 leads to 36-36 = 0
Therefore the equation below
product = 18*(sum) - 36
has been satisfied
-----------------------------------------
If x = 34, then x+2 = 34+2 = 36
product = x*(x+2) = 34*36 = 1224
sum = x+(x+2) = 34+36 = 70
then we can see that...
product = 18*(sum) - 36
1224 = 18*(70) - 36
1224 = 1260 - 36
1224 = 1224
So that works as well.
----------------------------------------
There are two possible outcomes
Either the integers are 0 and 2
OR
the integers are 34 and 36

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).

Answer:
1773.91 miles
Step-by-step explanation:
Given data
Completed miles= 816 miles
Percentage completion= 46%
Let the total distance be x
Hence
46% of x= 816
let us find x
46/100*x= 816
0.46x=816
x= 816/0.46
x= 1773.91
Therefore the total distance is 1773.91 miles

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]

What is the difference in the volume of a cylinder having a radius of 4 and a height of 8, and the volume of a rectangular prism having dimensions of length = 10, width = 7 and height = 6? Use 3.14.
Round to the nearest hundredth.
===========================================
Work Shown:
The cylinder has volume of...
V = pi*r^2*h
V = 3.14*4^2*8
V = 401.92
----------------
The rectangular prism has a volume of...
V = L*W*H
V = 10*7*6
V = 420
----------------
Subtract the two results:
420-401.92 = 18.08
The cylinder has roughly 18.08 more cubic units of volume compared to the rectangular prism.
Answer:
volume of cylinder: V=Sđ*h=R^2*3.14*8
volume of rectangular prism: V=Sđ*h=10*7*6

length of its diagonal. Round to the nearest tenth of a unit.
Answer:
d=11.7
Step-by-step explanation:
Patterns are made using straight lines and arcs.
Pattern A (one row)
Pattern B (two rows)
More rows are added to Pattern B so that
number of straight lines : number of arcs = 7:6
How many rows are added?
5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.
What is a pattern?
A pattern is a sequence. It can be an AP, GP also.
How to determine the number of rows to be added?
present ratio between number of straight lines and number of arcs
=8:9
When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.
Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.
Hence 5 rows are to be added in the pattern B to get the ratio 7:6.
