Is ABCD a parallelogram?

Mathematics
1 answer:
spayn [35]2 years ago
7 0

Answer:

Yes

Step-by-step explanation:

We know that because AB and CD are parallel,

  • angles A and D are supplementary
  • angles B and C are supplementary

As supplements of congruent angles are congruent, this means angle B is congruent to angle C.

Thus, ABCD is a parallelogram because it is a quadrilateral with 2 pairs of opposite congruent angles.

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find
notsponge [240]
So we need to cover 5.5% into a decimal. 

0.055 = 5.5%

The house value is 120,000.
So 

(1.055x) * (120,000)= 

So

f(x)=1.055x * 120,000

Amanda is a cabinetmaker. She makes cabinets using one of three types of wood: birch, maple, or cherry. She can finish each type
padilas [110]
Assume that each material in each category has an equal chance of being selected.

Categories:
(a) Type of wood used to make the cabinet: birch, maple, cherry.
     Each type of wood has a probability of 1/3 to be selected.
(b) Type of finish: transparent, semi-transparent.
    Each type of finish has a probability of 1/2 to be selected.
(c) Knob: bronze, steel, wood.
     Each material has 1/3 probability to be selected.

Each event (selecting material for the cabinet, for the finish, and for the knob) is an independent event.

Therefore
Probablity(birch wood AND bronze knob) = (1/3)*(1/3) = 1/9
Probability(wood knob) = 1/3
Probability(transparent stain) = 1/2
Probability(cheryy wood AND semi-transparent stain) = (1/3)*(1/2) = 1/6
