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.
Answers
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]

Answer:
x ≈ 136.7 ft
Step-by-step explanation:
As you have marked, the relevant sides are the adjacent side and the hypotenuse. The mnemonic SOH CAH TOA reminds you ...
Cos = Adjacent/Hypotenuse
For this triangle, that means ...
cos(43°) = (100 ft)/x
x = (100 ft)/cos(43°) . . . . . . . . . . multiply both sides by x/cos(43°)
x ≈ 136.73 ft
The length x is about 136.7 feet.

12x = 60
x = 5
Answer:
5 boys
Step-by-step explanation:
Write it like this:
3/X=12/20
Then, cross multiply.
3*20=60
X*12=12X
12X=60
Divide both sides by 12
60/12=5
X=5
The unknown number is 5
If there are 3 girls, then there are 5 boys.

6. There are 785 students in the senior class. If there are 77 more females in
the class than males, how many male and female seniors are there?
... please solve this using if systems of equations
Answers
Answer:
there are 431 females and 354 males in the class
Step-by-step explanation:
Let the number of females student in the class be x
Let the males by y
If there are 785 students in the senior class, then;
x+y = 785 .... 1
If there are 77 more females in the class than males, then;
x = y+77 ....2
Substitute 2 into 1
y+77+y = 785
2y = 785 - 77
2y = 708
y = 708/2
y = 354
Since x = 785 - y
x = 785 - 354
x = 431
Hence there are 431 females and 354 males in the class
Given (11,2) and (x,−4), find all x such that the distance between these two points is 10. Separate multiple answers with a comma.
Answers
Answer: x = 3, 19
Step-by-step explanation:
Given
Two points i.e. [tex](11,2)\ \text{and}\ (x,-4)[/tex] are given
Distance between them is 10 units
Distance is given by the distance formula
[tex]\Rightarrow d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Distance between two points is
[tex]\Rightarrow 10=\sqrt{(x-11)^2+(-4-2)^2}[/tex]
Squaring both sides
[tex]\Rightarrow 100=(x-11)^2+(-6)^2\\\Rightarrow 100=x^2+121-22x+36\\\Rightarrow x^2-22x+57=0\\\Rightarrow x^2-19x-3x+57=0\\\Rightarrow x(x-19)-3(x-19)=0\\\Rightarrow (x-19)(x-3)=0[/tex]
i.e. [tex]x\ \text{can be }\ x=3\ or\ 19[/tex]
Find the Cartesian equation of the curve with parametric equations x = 2 sec(t) and y = 3 tan(t) for t ∈ π/2 , 3π/2, and describe the curve.
Answers
Answer:
4y^2 - 9x^2 = -36
Step-by-step explanation:
x = 2 sec t
y = 3 tan t
x^2 = 4 sec^2 t
y^2 = 9 tan^2 t
Now sec^2t = 1 + tan^2 t so we have:
4(1 + tan^2 t) + 9 tan^2 t = x^2 + y^2
4 + 13 tan^2 t = x^2 + y^2
13 tan^2 t = x^2 + y^2/ - 4
tan^2 t = x^2/13 + y^2/13 - 4/13
But , from the second equation tan t = y/3 so tan^2 t = y^2/9, so:
y^2/9 = x^2/13 + y^2/13 - 4/13
LCM of 9 and 13 is 117 so multiply thru by 117:
13y^2 = 9y^2 + 9x^2- 36
4y^2 - 9x^2 = -36

A regular pentagon has sides of 10 cm. Find the radius of the largest circle which can

Answers
Answer is 6.88 cm
Divide the pentagon radially into five congruent, isosceles triangles. Each triangle has a vertex angle of 360°÷5=72° and altitude of 5÷tan(36°).
radius of circle = 5÷tan(36°) = 6.88 cm
can anyone do this quickly?
Answers
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
