Olivia has a 20 meter-long fence that she plans to use to enclose a rectangular garden of width w. The fencing will be placed around all four sides of the garden so that its area is 18.75 square meters. Write an equation in terms of w that models that situation.
Answer:
Step-by-step explanation:
Length of garden = 10-w
Area = (10-w)w = 18.75
w² - 10w + 18.75 = 0
Answer is [tex]w^{2} - 10w + 18.75 = 0[/tex]
Rectangle Formulas:
Area of the Rectangle (A) = length x breadth.
Perimeter of rectangle (P) = 2 x (length + breadth)
(Given),
A = 18.75square meters
P = 20 meter
Let's length be l and width be w.
P = 2 (l + w)
20 = 2(l + w)
l + w = 10
l = 10 - w ----( 1 )
Now, A = l x w
18.75 = (10 - w) x w
18.75 = 10w - [tex]w^{2}[/tex]
[tex]w^{2} - 10w + 18.75 = 0[/tex]

vamsi is X years old.his brother is 3 years elder to him. his uncle is 4 times his age and his aunt is 5 years younger than his uncle.what are the ages of vamis brother, uncle and aunt? what will be the age of his uncle 6 years from now
pls send the ans fast
Step-by-step explanation:
Vamsi is X years old
Vamsi = X
his brother is 3 years elder to him
Brother = X + 3
his uncle is 4 times his age
Uncle = 4X
his aunt is 5 years younger than his uncle
Aunt = Uncle - 5
what will be the age of his uncle 6 years from now
= 4X + 6
what are the ages of vamis brother, uncle and aunt?
Assume Vamis = 15 years
Brother = X + 3 = 15 + 3 = 18
Uncle = 4X = 4 * 15 = 60
Aunt = Uncle - 5 = 60 - 5 = 55
what will be the age of his uncle 6 years from now
Uncle = 4X + 6 = 60 + 6 = 66

what is the value of x and y?
Answer:
The right answer is x = 8, y = 40.
Step-by-step explanation:
Since this triangle is isosceles we know that...
∠ACB = ∠ABC
40° = (5x)°
40 = 5x
x = 40 / 5
x = 8
We also know that the sum of all angles inside the triangle is equal to 180°, therefore...
∠BAC = 180° - ∠ACB - ∠ABC
(2y + 20)° = 180° - 40° - 40°
2y + 20 = 100
2y = 100 - 20
2y = 80
y = 80 / 2
y = 40
From this, we know that the right answer is x = 8, y = 40.

How did you compute sums of dollar amounts that were not whole numbers?
Answer:
$7.34
Step-by-step explanation:
To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :
$5.89 + $1.45
Taking the whole numbers first:
$5 + $1 = $6
Take the sum of the decimals :
$0.89 + $0.45 = $1.34
Sum initial whole + whole of sum of decimal
$6 + $1 = $7
Remaining decimal : $1.34 - $1 = $0.34
$7 + $0.34 = $7.34

Find the value of x when (a) 9 : x : : 54 : 48 (b) 2, 6 , x are in continued proportion
Answer:
a) x = 8
b) x = 18
Step-by-step explanation:
Given that
9 : x : : 54 : 48
This may be rewritten as
9/x = 54/48
cross multiply
9 * 48 = 54 * x
Divide both sides by 54
x = 9 * 48/54
= 8
b Given that 2, 6, x are in continued proportion then
2/6 = 6/x
2 * x = 6 * 6
x = 36/2
= 18

can anyone do this quickly?
Answer:
4th option (x = 60)
Step-by-step explanation:
This is isosceles triangle so the angles are the same. Think of this as an mirror. AE is the same as BE so you can assume angle ABE is 30 degrees.
30+30=60
180-60=120
So angle AEB is 120.
That is supplementary angle so the other side must be 180-120=60.
So, the middle smaller triangle is isosceles as well, so BED and BDE are both 60.
60+60=120, 180-120=60
So angle x = 60

We call the square root curve a "relation" because it is not a function. A relation that is a function will have only one y-value for each x-value. For positive x-values, there are two square roots.
