Answer:
64° and 116°
Step-by-step explanation:
Supplementary angles sum to 180°
let one angle be x then the other is 2x - 12 ( 12 less than twice the other )
Sum the 2 angles and equate to 180
x + 2x - 12 = 180
3x - 12 = 180 ( add 12 to both sides )
3x = 192 ( divide both sides by 3 )
x = 64
The 2 angles are x = 64° and 2x - 12 = (2 × 64) - 12 = 128 - 12 = 116°
Answer:
4 T-shirts and 5 long sleeves shirts.
Step-by-step explanation:
T-shirt cost =$10
Long sleeve shirt cost = $15
Total number of shirts = 9
Total number of T-shirts = 4
Cost of 4 T-shirts = 4 × 10 =$ 40
Total number of long sleeve shirt = 5
Cost of 5 long sleeve shirt = 5 × 15 =$ 75
Verification:
75+40 = $115 proved!

Answer:
32 units^2
Step-by-step explanation:
This is a trapezoid
The area of a trapezoid is found by
A = 1/2 (b1+b2) h
A = 1/2 ( 4+12) *4
A = 1/2 (16) *4
A =32
Answer:
simple interest formula-
I = PRT
where,
I = simple interest,
P= principle(basic investment or loan),
R= annual interest
T= relevant time period
I = PRT
I = 45000× 3.5/100× 1
I = 1575
answer = 1575
