Answer:
Dimensions are 2 and 4
Step-by-step explanation:
Area= a*b=8
Perimeter=2(a+b)=12 => a+b = 12/2. a+b = 6
a+b=6 =>a=6-b
If a=2=>b=4 so 4+2=6 , 4*2=8 and 4*2+2*2=12
If a=4=>b=2 so 4+2=6 , 4*2=8 and 4*2+2*2=12
Dimensions are 2 and 4
The possible dimensions of the table are -
L = 2, B = 4.
or
L = 4, B = 2.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is a rectangular table top has an area of 8 ft and a perimeter of 12 ft.
Let the dimensions of the rectangular table be {x} ft and {y} ft respectively.
We can write -
xy = 8 ....... Eq(1)
2(x + y) = 12
x + y = 6 ....... Eq(2)
y = (6 - x)
Then, we can write -
x(6 - x) = 8
- x² + 6x = 8
x² - 6x + 8 = 0
(x - 2)(x - 4) = 0
We get -
x = 2 and x = 4
Now,
For x = 2, y = 4.
For x = 4, y = 2.
Therefore, the possible dimensions of the table are -
L = 2, B = 4.
or
L = 4, B = 2.

Step-by-step explanation:
A wire is bent to form semi circles as shown below. How long is the wire? Use 3.14 for pi and round your answer to the nearest hundredth if necessary
4 semi circles and the diameter is 41
======================================================
Explanation
Those 4 semicircles can be joined to form 4/2 = 2 full circles.
Each circle has diameter 41 cm.
Let's find the circumference of one circle
C = circumference, d = diameter = 41, pi = 3.14
C = pi*d
C = 3.14*41
C = 128.74
That's the perimeter of one full circle. Double it to get
2*128.74 = 257.48 cm
Which is the total length of the wire.
Which means "p decreased by 75"?

Step-by-step explanation:
Sharon has two liabilities: a credit card balance of $1300 and a car loan balance of $4800. Sharon car has a market value of $9000 she also has a balance of $1450 in her saving account and has stocks that are currently worth $1050. What is Sharon’s net worth?
Given:
Sharon has two liabilities: a credit card balance of $1300 and a car loan balance of $4800.
Car = $9000
Balance in her saving account = $1450
Stocks = $1050.
To find:
Sharon’s net worth.
Solution:
Total liabilities = Credit card balance + Car loan balance
= $1300 + $4800
= $6100
Total Assets = Car + Balance in her saving account + Stocks
= $9000 + $1450 + $1050
= $11500
Now,
Net worth = Total assets - Total liabilities
= $11500 - $6100
= $5400
Therefore, Sharon’s net worth is $5400.
Sharon's net worth, based on her assets and liabilities, is $5,400.
What is the net worth?Net worth refers to the difference between an individual's assets and liabilities.
Assets are the properties owned by the individual. Liabilities are the sources of funding for the assets. They are financial obligations owed to outsiders (creditors).
In business, the net worth of an entity is known as equity.
Data and Calculations:Liabilities:Credit card balance of $1300
Car loan balance of $4800
Total liabilities = $6,100
Assets:Sharon's car with a market value of $9000
Savings account balance of $1450
Stocks that are currently worth $1050
Total assets = $11,500
Net worth = $5,400 ($11,500 - $6,100)
Thus, Sharon's net worth is $5,400.

Answer:
5.25/25=0.21
Step-by-step explanation:
to find this you can do 0.21 times 25 which gets 5.25 so there is your answer
5.25/25=0.21 is the unit price per card.
What is division?Division is the process of splitting a number or an amount into equal parts.
Here, given that,
A store sells a package of 25 trading cards for $5.25.
So, price of per card = 5.25/25
=0.21
(to find this you can do 0.21 times 25 which gets 5.25 )
Hence, 0.21 is the unit price per card.

Function A(e) represents the surface area of a cube in terms of its edge length, e, and the difference quotient is 12e + 6h. What is the average rate of change in surface area of a cube as the edge length increases from 3 inches to 5 inches?
48 square inches per inch
54 square inches per inch
66 square inches per inch
96 square inches per inch
Answer: 48 square inches per inch
Step-by-step explanation:
The surface area of a cube of sidelength e is:
A(e) = 6*e^2.
The rate of change is:
A'(e) = 2*6*e
The average rate of change between 3 in and 5 in is:
r = (A(5in) + A(3in))/2 = (2*6*5in + 2*6*3in)/2 = 48in
Now, the options are given in:
"squere inches per inch"
This is written as:
in^2/in = in.
Then we can write our above rate as:
r = 48in = 48in^2/in = 48 square inches per inch.
Answer:
Just did the test, 48 square inches is correct on edge

Parallel lines have the same slope.
m = (y2-y1)/(x2-x1)
m = (-3-3)/(4-0)
m = -6/4 = -3/2
Substitute the values in y = mx + c,
-5 = (-3/2)(6) + c
-5 = -9 + c
c = 4
y = (-3/2)x + 4
Thus, Option D is the correct answer

Often we need to use exponents to correctly model the variation in situations:
The volume of a cylinder varies jointly with the square of its radius and its height. Its
general equation looks like V = kr’h where k= some constant number for all cylinders
and V, rand h are variables representing volume, radius and height, respectively. When
the radius is 3 cm and height is 5 cm, the cylinder has a volume of 141.3 cm. Find the
volume when the radius is 6 cm and the height is 10 cm.
Answer:
V = 1130.4 cm³
Step-by-step explanation:
Given that V varies jointly with r² and h then the equation relating them is
V = kr²h ← k is the constant of variation
To find k use the condition when r = 3 and h = 5 then V = 141.3 , then
141.3 = k × 3² × 5 = 45k ( divide both sides by 45 )
k = 3.14 ← note approximation for π
V = 3.14r²h ← equation of variation
When r = 6 and h = 10, then
V = 3.14 × 6² × 10 = 3.14 × 36 × 10 = 1130.4 cm³
