A. antisymmetric
B. irreflexive
C. transitive
D. reflexive
E. symmetric
(b) a and b have a common grandparent;
A. reflexive
B. symmetric
C. irreflexive
D. transitive
E. antisymmetric
(c) a has the same first name as b;
A. reflexive
B. irreflexive
C. transitive
D. symmetric
E. antisymmetric
(d) a and b were born on the same day;
A. symmetric
B. reflexive
C. transitive
D. antisymmetric
E. irreflexive
Answer:
a) Options A, B & D.
b) Options C & D.
c) Options C, D & E
d) Options A, B & C
Step-by-step explanation:
a) Options A, B & D.
- It's irreflexive because b is not older than a.
- It's transitive because if a is older than b as we are told and b is older than c, then we can say that a is older than c.
- It's antisymmetric because if a is older than b, then we can say that b is not older than a.
b) Options C & D.
- It's symmetric because if a & b have a common grandparent, then we can say that b and a have a common grandparent.
- It's reflexive because a and b have common grandparents and thus implies all of a's grandparents.
c) Options C, D & E are correct.
It could be Transitive, symmetric or antisymmetric.
d) Options A, B & C are correct.
Sabrina bought a hoodie at the store when they were having a 25% off sale. If the regular
price of the hoodie was $50, how much did Sabrina save?
Answer:
$12.50

Given: M ≅ X
N ≅ Y
YO ≅ NZ
Prove: △MNO ≅ △XYZ
Answer:
Δ MNO ≅ ΔXYZ ⇒ proved down
Step-by-step explanation:
Cases of congruency
SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ HL ⇒ hypotenuse and leg of the 1st right Δ ≅ hypotenuse and leg of the 2nd right ΔLet us solve the question using the 4th rule above
∵ YZ = YO + OZ
∵ NO = NZ + ZO
∵ OZ = ZO ⇒ from the figure
∵ YO ≅ NZ ⇒ given
∴ YZ ≅ NO
In Δs MNO and XYZ
∵ ∠M ≅ ∠X ⇒ given
∵ ∠N ≅ ∠Y ⇒ given
∵ NO ≅ YZ ⇒ proved
→ By using the AAS postulate of congruency.
∴ Δ MNO ≅ ΔXYZ

A glass is
1
6
full. Then 95cm3 of orange juice is poured in.
The glass is now
4
5
full. What is the total volume of the glass?
Answer:
let x = the amount of orange juice in a full glass.
the glass is 1/6 full = 1/6 * x
add 95 cubic centimeters and the glass becomes 4/5 full.
equation for that is:
1/6 * x + 95 = 4/5 * x
subtract 1/6 * x from both sides of this equation to get:
95 = 4/5 * x - 1/6 * x
multiply 4/5 * 6/6 and multiply 1/6 * 5/5 and the equation becomes:
95 = 24/30 * x - 5/30 * x
combine like terms to get 95 = 19/30 * x
multiply both sides of the equation by 30/19 to get:
30/19 * 95 = 30/19 * 19/30 * x
simplify to get:
30/19 * 95 = x
solve for x to get x = 150.
the volume of the glass is 150 cubic centimeters.
1/6 * 150 = 25
4/5 * 150 = 120
the difference between 4/5 full and 1/6 full is 95 cubic centimeters.
solution is that the volume of the glass is 150 cubic centimeters.

Here is a list of numbers:
0, 10,-18, 7, -14,-7,7,-14,13,0
State the median.
describe how you would graph 2x+3y=6
Answer:
First get y by itself. (y=-2/3x +2). The y-intercept is at 2 and the slope is -2/3 so starting at (0,2) you would go down two and right three and continue doing that to create your graph.

Three weeks ago, an art supply store started selling a paint kit for 75% of the original price. Now the kit is 15% off of the sale price. The expression 0.75x - 0.15(0.75x) represents the current price of the paint kit where x is the kit’s original price (in dollars). Find the current price of the kit if it originally cost $48.
Answer:
$30.60
Step-by-step explanation:
0.75X-0.15(0.75X)
0.75(48)-0.15(0.75(48))
0.75(48)-0.15(36)
36-0.15(36)
36-5.4
