The answer would be A) X=5
Answer:
y = -9.3
if they are complementary it is 45 degrees
if they are supplementary it is 90 degrees
Step-by-step explanation:
-12.7 = y -3.4
-12.7 + 3.4 = y -3.4 + 3.4
-9.3 = y
complementary angles equal to 90 degrees
supplementary angles equal to 180 degrees
vertical angles have same degrees
so 90/2= 45
180/2 =90
Answer: 120
Step-by-step explanation:
From the question, we are informed that there are 10 people in a math club and that three people will be chosen for the Pi Day committee.
The number of different ways that the club members can structure the committee goes thus:
This can be solved by:
nCr = n! / r! (n - r)!
where n = 10
r = 3
= n! / r! (n - r)!
= 10! / 3! (10 - 3)!
= (10 × 9 × 8) / (3 × 2)
=120

The total percent discount on the jeans is 35% amounting to $77
<h3>Discount</h3>
- Cost of a pair of jean = $220
- Discount from last season = 15%
- Discount from Thanksgiving day = 20%
Total percentage discount = 15% + 20%
= 35%
Amount of discount = Total percentage discount × Cost of a pair of jean
= 35% × $220
= 0.35 × 220
= $77
Therefore, the total percent discount on the jeans is 35% amounting to $77
