The area of the opening of a rectangular window is to be 120 square feet. If the length is to be 2 feet more than the width, what are the dimensions
Answers
Answer:
Width = 10ft
Length = 12ft
Step-by-step explanation:
For a rectangle of length L and width W, the area is calculated as:
A = L*W
In this case, we know that:
The area is 120 ft^2.
The length is 2 ft more than the width.
Then we can write:
L = W + 2ft.
If we use these two equations and replace them in the equation for the area of a rectangle, we get:
A = 120ft^2 = W*L = W*(W + 2ft)
120ft^2 = W*(W + 2ft)
Now we can solve this for W
120 ft^2 = W^2 + 2ft*W
Now we can rewrite this as:
W^2 + 2ft*W - 120ft^2 = 0
The solutions of this equation can be found by the Bhaskara's formula.
We know that for an equation of the form:
a*x^2 + b*x + c = 0
The two solutions are given by:
[tex]x = \frac{-b +\sqrt{b^2 - 4*a*c} }{2*a}[/tex]
in our case, we have:
a = 1
b = 2ft
c = -120ft^2
Then the solutions for the equation W^2 + 2ft*W - 120ft^2 = 0 are:
[tex]W = \frac{-2ft + -\sqrt{(2ft)^2 - 4*1*(-120ft^2)} }{2*1} = \frac{-2ft +- 22ft}{2}[/tex]
Then the two solutions are:
W = (-2ft - 22ft)/2 = -12ft (this is a negative measure, does not have a real meaning in this case, so this solution can be discarded)
The other solution is:
W = (-2ft + 22ft)/2 = 10ft (this is the correct solution)
Then the width is 10ft, and we know that the length is 2 ft longer than the width, then the length is:
L = W + 2ft = 10ft + 2ft = 12ft

What is a recession in an economy?
A recession is defined as a severe fall in economic activity that lasts more than a few episodes of time and is reflected in real GDP, income, employment, economic growth.
So if an economy is in a recession and vehicle prices drop by eight percent.
Then, we have:
= $25,295 × 8%
[tex]\mathbf{= 25295 \times \dfrac{8}{100}}[/tex]
= $2023.6
The price of a car that was previously worth 25,295 will be:
= $25295 - $2023.6
= $23271

A sign in front of a roller coaster says you must be 40 inches tall to ride what percentage of this height is 34 inches
Answers
Answer:
85% of 40
Step-by-step explanation:
We can do this in two ways, we can either use percent proportions or use benchmark percentages. I'll do both.
So the equation for percent proportions will look something like this:
34/x = 40/100
So to solve this, we do 34*100/40, which is 3400/40 which equals 85. That means that 34 is 85% of 40 inches.
Another way to do this is to use benchmark percents:
10% of 40 is 4 and, so you do 40-4 and get 36. Then we need to get 2 more down so we do 5% of 40 which is 2, so we do 36-2 or 40-6.
Then we add up the percents which would add up to 15%, we do 100-15 and get 85%
Or we could just say, well 6 is 15% of 40 so we do 100-15 and 40-6 and get that 34 = 85% of 40

the perimeter of a rectangular field is 374 yards. if the width of the field is 88 yards, what is its length
Answers
Answer:
99 yards
Step-by-step explanation:
374 - 88 = 286
286 - 88 = 198
198/2 = 99
length = 99
The required length of the given rectangular field is 99 yards.
What is a rectangle?A rectangle is a type of parallelogram having equal diagonals.
All the interior angles of a rectangle are equal to the right angle.
The diagonals of a rectangle do not bisect each other.
Given that,
the perimeter of rectangular field is 374 yards.
And its width is 88 yards.
Suppose the length is x yards.
Since the perimeter of a rectangle is given as P= 2(l + b), where l is the length and b is the width .
Substitute the respective values to get,
374 = 2(88 + x)
=> 2x = 374 - 176
=> 2x = 198
=> x = 99
Hence, the length of the rectangular field is given as 99 yards.
