Notice that 38 and 52 make a total of 90
sinA=cos(90-A)
sin38=cos52, therefore the answer is zero
Answer:
Since it is vertical angles, 4x - 12 = 88.
Answer is 25
Step-by-step explanation:
88 + 12 = 100
100 / 4 = 25

Answer:
A √2 is an irrational number
Step-by-step explanation:
A: √2 ≈ 1.4142135623730950488... an infinite non-repeating decimal (irrational)
B: √4 = 2 (rational)
C: ∛8 = 2 (rational)
D: √16 = 4 (rational)
ANSWER
EXPLANATION
The given fractions are:
We factor to obtain:
We cancel the common factors to get:
We multiply the numerators and also multiply the denominators to get:
Therefore the two fractions simplifies to
The price difference/ the original price and times the whole equation by 100 (to get the percentage).
> ($50/$150) x 100 = 33% (rounded)
