How do I solve A B C ?

Answers

Answer 1

Answer:

Answer:

see explanation

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

Thus CO = OA = a

(a)

CA = CO + OA = a + a = 2a

(b)

AB = AO + OB = - a + b = b - a

(c)

BC = BO + OC = - b - a

Answer 2

Answer:

Answer:

(a) CA=CO+OA=a+a=2a

(b) AB=AO+OB=-a+b=b-a

Step-by-step explanation:

a) CA=CO+OA=a+a=2a

(b) AB=AO+OB=-a+b=b-a

Adam uses coconut milk for the desert the coconut milk is in the can the can is 12 cm high and diameter of 8 cm the formula V equals three are 2H how much coconut milk is in the can

Answers

The last portion of the problem is not making sense (?)

However, if one assumes that the can is a straight circular cylinder, the volume of the can:

V = (PI)[(D/2)^2](H)

Given H = 12 cm, and D = 8 cm, substituting these values:

V = PI[(8/2)^2](12)

= 603.1857 cm^3

Is it possible for a trapezoid to have 3 right angles

Answers

No, because if a trapezoid were to have three right angles, the fourth angle would also be right, because the angles of a quadrilateral add up to 360, and a quadrilateral with four right angles is a rectangle, which has two sets of parallel sides instead of one set like a trapezoid does.

No, this is because if a trapezoid has 3 right angles, the fourth and last one would also have to be a right angle and it is supposed to be an acute angle. To make it less confusing, a right angle is is in the shape of a "L" and if it had three "L's" it would have to have another one too which would then make it a rectangle. I hope I helped!!

If x = 11 and y = 7, what is the value of the following expression?
x - 8 + 4y

Answers

I think it is 31 I might be wrong but I tried :)

If you change the x with the 11 and the y with 7, you subtract the 8 from 11, than add 4 times 7. And you get 31

Write 6)15 as a fraction with a denominator of 20

Answers

Consider the numbers in the fraction:
6 is 2 times 3
The denominator 15 is 5 times 3
Numerator : Denominator = 6 : 15 or 2 : 5
If the Denominator is to be 20 it is 4 times 5,
the Numerator has to be 4 times 2
Answer:
6/15 = 8/20
