Answer:
$42.12
Step-by-step explanation:
35% off means she has to pay:
100 - 35 = 65% of the marked price.
65/100 × 60 = 39
Tax: 8%
8/100 × 39 = 3.12
To pay:
39 + 3.12 = 42.12
Her new balance is her new balance would be 435
heres my math
750-150-135=435
H=√d^2-w^2
=√146.4 1-92.16
=7.3 inches
the principle used here is pythagoras theorem
all the best.
Answer:
$33
Step-by-step explanation:
C = 6(3) + 15
C = 18 + 15
C = 33
Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles given and equate to 180
4x - 13 + 15 + x + 18 = 180 ( simplify left side )
5x + 20 = 180 ( subtract 20 from both sides )
5x = 160 ( divide both sides by 5 )
x = 32
∠A = 4x - 13 = (4 × 32) - 13 = 128 - 13 = 115°
∠C = x + 18 = 32 + 18 = 50°
As a check : 115° + 15° + 50° = 180° ← correct
