Answer:
19.30
Step-by-step explanation:
if your finding the discounted price, you'd take 20% and turn it into .20 and then subtract 19.50 and .20
Step-by-step explanation:
sin(2x) + cos(3x)
Use double angle formula sin(2x) = 2 sin x cos x.
Use triple angle formula cos(3x) = 4 cos³x − 3 cos x.
Substitute:
2 sin x cos x + 4 cos³x − 3 cos x
Answer:
Option A and C is correct.
Step-by-step explanation:
Discount is defined as a reduced price on something being sold or at a price lower than that item is normally sold for.
For a 20% discount,
Given:
Initial prices = $ d
Discounted price = % discount × original/initial cost
= 20/100 × d
= 0.2 × d
Selling price = original cost - discounted price
= d - 0.2d
= 0.8 × d
= 0.8d
26 x 3 would be 78 so that's the total 3rd grade students in the school if 4 are gone the it would be 78-4= 74 so the answer would be 74 students
