Answer:
p=20cm
Step-by-step explanation:
Area of parallelogram is :
Since, it is a parallelogram, the four triangles are created by drawing diagonals of equal area=
.
Now, Height of the one triangle is 2cm and the other is 3 cm.
Therefore, From ΔODC,
Area=
=
Again, from ΔOAD,
Area=
Now, opposite sides of parallelogram are equal, therefore,AD=BC=4cm and DC=AB=6cm.
Perimeter of parallelogram= Sum of all the sides
=AB+BC+CD+AD
=6+4+6+4
=20cm
Answer:
1041.44
Step-by-step explanation:
A=2πrh+2πr^2
=2π6.5×19+2π6.5^2≈1041.43796
Answer is A. 12c
A monomial only consists of one term (12c),
Binomials consist of two terms (c^2 - 16)
Trinomials consist of three terms (c^2 + c + 6)
An easy way of remembering which is which is to look at the prefixes.
Mono= 1
Bi= 2
Tri= 3
He makes 240. All you do is make the 8% to a decimal (.8) and them multiply it by 3000. (3000*.08) It should be 240.
Answer:
Original Price = 160
Sale Price =40
Step-by-step explanation:
Let Original Price be x and Sale Price be y
y=1/4 of x (Equation 1)
x=120+y (Equation 2)
Put value of x from equation 2 in equation 1
y= (1/4)*(120+y)
y=120/4 + y/4
y-y/4=30
3y/4=30
y=30*4/3
y=40
Put value of y in Equation 2
x=120+40
x=160
