Step-by-step explanation:
Area of parallelogram is
A = base of parallelogram x height of parallelogram
= 14 x 12 = 168 sq feet
Break parallelogram down into figures
There would be 2 triangles and 1 square
Area of 1 triangle = 0.5 (3 x 12) = 18
Area for 2 triangles = 2 x 18 = 36
Area of square = base x height
= 11 x 12 = 132
132 + 36 = 168
Area of parallelogram is 168 sq feet
find the value of x and y in the parallelogram
Answer:
x=14
y=40
Step-by-step explanation:
A parallelogram is like a rectangle 2 parallel sides are equal.
so x+3=17 and y-2=38
x+3=17
x=17-3
x=14
y-2=38
y=38+2
y=40

Use the formula for simple interest to help solve the following questions
Answer:
1. ₹ 382.50
2. ₹ 14,583.33
3. 6%
Step-by-step explanation:
Interest = p × r × t
p = principal amount
r = rate of interest
t = time in years
(1) Interest = 10,200 × 0.025 × 1.5
= ₹ 382.50
(2) Principal = [tex]\frac{I}{(r\times t)}[/tex]
= [tex]\frac{1750}{(0.04 \times 3)}[/tex]
= [tex]\frac{1750}{0.12}[/tex]
= ₹ 14,583.33
(3) [tex]Rate=\frac{(I \times 100)}{(p \times t)}[/tex]
[tex]=\frac{(1186.5 \times 100)}{(5650 \times 3.5)}[/tex]
[tex]=\frac{118650}{19775}[/tex]
= 6%
A debt of $9000 is to be amortized with 4 equal semiannual payments. If the interest rate is 7%, compounded semiannually, what is the size of each payment?
Answer:
Instalment = Loan / PVAF (r%, n)
Where r is int rate per six months & n is no. of half years
= $ 9000 / PVAF (5% , 4)
= $ 9000/ 3.5460
= $ 2538.11

triangle area ?
Answer:
A= 21.65063509
Step-by-step explanation:
triangle area is =base*hight/2
Because we have a right triangle we can apply the trigonometric functions
sin30 =base/hypothenuse = base/10
cos 30 = hight/hypothenuse =hight/10
sin30 = base /10 ; multiply both sides by 10
base = 10*sin30
cos 30 = hight /10 ; multiply both sides by 10
hight = 10 cos 30
A= 10*sin30*10*cos30/2 =
100*sin 30*cos 30/2=
50*sin30*cos30 = ; use calculator make sure is set up in degrees
A= 21.65063509

Tessellations (image below)
9514 1404 393
Answer:
regular octagon
Step-by-step explanation:
In order for a shape to tessellate a plane, there must be a way to arrange the shapes so that the sum of angles at a node is 360°. An arrangement of kites is shown in the attachment. Of course, squares are used to tile planes all the time, as their four 90° corners fit together nicely.
An octagon has internal angles of 135°, which is not a sub-multiple of 360°. Hence there is no way for octagons to fit together to tile a plane.
Octagons will not tessellate a plane.

C. $27,100
OD. $20,876
9514 1404 393
Answer:
A. $26,346
Step-by-step explanation:
The cost is the sum of all of the payments made:
cost = down payment +24×monthly payment +deposit +acquisition fee +after-lease price
cost = $1500 +24×279 +350 +700 +17100 = $26,346
The total price of the car if you buy it after leasing is $26,346.

Well, I really don’t like graphic approaches in math, so hear ya go a formula:
Although there are easier ways that work for some quadratics, but this formula works for them all. (It is atached, have a look)
So,
( -(-2)+- square root of ((-2)^2-4(1)(-40)) ) / 2(1)
Note that for a hear I use one, since there is nothing in front of x.
( 2 + (12.8) ) / 2 < with plus
( 2 -(12.8) ) / 2 < with minus
X = 7.4
Or
X = -5.4

find two numbers whose ratios is 3 to 5 and whose sum is 88
Answer:
33 and 55
Step-by-step explanation:
[tex]\frac{x}{y}: \frac{3}{5}[/tex]
x + y = 88
3 + 5 = 8
[tex]y(\frac{x}{y}): y(\frac{3}{5})[/tex]
[tex]x= \frac{3}{5}y[/tex]
[tex]y+\frac{3}{5}y=88[/tex]
[tex]\frac{8y}{5}=88[/tex]
[tex]5(\frac{8y}{5})=5(88)[/tex]
8y = 440
8y ÷ 8 = 440 ÷ 8
y = 55
x + y = 88
x + 55 = 88
x + 55 - 55 = 88 - 55
x = 33

A rectangle is to be inscribed in an isosceles right triangle in such a way that one vertex of the rectangle is the intersection point of the legs of the triangle and the opposite vertex lies on the hypotenuse. Find the largest area (in cm 2 ) of the rectangle and its dimensions (in cm) given that the two equal legs of the triangle have length 4.
Answer:
x = 2 cm
y = 2 cm
A(max) = 4 cm²
Step-by-step explanation: See Annex
The right isosceles triangle has two 45° angles and the right angle.
tan 45° = 1 = x / 4 - y or x = 4 - y y = 4 - x
A(r) = x* y
Area of the rectangle as a function of x
A(x) = x * ( 4 - x ) A(x) = 4*x - x²
Tacking derivatives on both sides of the equation:
A´(x) = 4 - 2*x A´(x) = 0 4 - 2*x = 0
2*x = 4
x = 2 cm
And y = 4 - 2 = 2 cm
The rectangle of maximum area result to be a square of side 2 cm
A(max) = 2*2 = 4 cm²
To find out if A(x) has a maximum in the point x = 2
We get the second derivative
A´´(x) = -2 A´´(x) < 0 then A(x) has a maximum at x = 2
The maximum area of the rectangle inscribe in the right isosceles triangle
is [tex]\rm \bold{4\;cm^2}[/tex]
Given that a rectangle is to be inscribed in an isosceles triangle
As per the attached figure we can write the following
Let ΔABC represents the isosceles triangle from the given data in the question we can write the following observations
Length of AB = 4
Length of BC = 4
∠ACB = 45°
∠BAC = 45°
Length of AC = [tex]\rm 4\sqrt2[/tex]
We have to consider a rectangle within the isosceles triangle such that
area of rectangle is maximum
The area of rectangle is given by equation (1)
[tex]\rm Area \; of \; rectangle = Length \times Breadth ........(1) \\[/tex]
Let the area of rectangle inscribed by the isosceles triangle is " A"
Let the lenght of the rectangle be "x "
Let the width of the rectangle be " y "
So according to equation (1) the area of rectangle inscribed into the triangle is given by
[tex]\rm A = x \times y.......(2)[/tex]
In ΔAED we can write
[tex]\int\limits^a_b {x} \, dx \rm tan 45= \dfrac{Perpendicular}{Base } = \dfrac{4-y}{x} \\1 = \dfrac{4-y}{x} \\ x = 4-y .......(3) \\[/tex]
From equation (2) and (3) we get
[tex]\rm A = (4-y)(y) \\A = 4y -y^2......(4)[/tex]
On differentiating the given function with respect to y we get
[tex]\rm A' = 4- 2y \\[/tex]
On putting A' =0 we get
[tex]\rm 4-2y =0 \\2y = 4\\y = 2[/tex]
A'' is negative hence it is the maximum value of y
So we can conclude that the maximum value of y is 2
So from equation (4) the maximum area is [tex]\rm 2\times 2 = 4\; cm^2[/tex]
The maximum area of the rectangle inscribe in the right isosceles triangle
is [tex]\rm \bold{4\;cm^2}[/tex]
