Answer:
x = 8.8
Step-by-step explanation:
take 20 degree as reference angle .the,
hypotenuse = OQ = x (hypotenuse is always opposite of 90 degree)
perpendicular(opposite) = PQ 3 (opposite of reference angle is perpendicular or also called as opposite)
base(adjacent) = OP (side which lies on the same line where 90 degree and reference angle)
using sin rule
sin 20 = opposite / hypotenuse
0.34 = 3 / x
x = 3/0.34
x = 8.82
x = 8.8
Answer:
Step-by-step explanation:
A. "a pair of pants originally priced at &40$ and a shirt originally priced at $45. He pays $55"—correct
(1-0.30)$40 + (1-0.40)$45 = $55
B. "Mary buys two shirts originally priced at $25. She will pay $35."—incorrect
2×(1-0.40)$25 = $30
C. "a pack of four shirts on sale for $37.80. The pack of shirts was originally priced at $54"—incorrect
(1-0.40)$54 = $32.40
D. "a pair of pants for sale price of $40.60. The pair of pants was originally priced at $58."—correct
(1-0.30)$58 = $40.60
Answer:
there are 4.3 weeks in a month
so then,

Answer:
C
Step-by-step explanation:
Given
f(x) = 3x - 40 and f(x) = 8 , then equate the right sides, that is
3x - 40 = 8 ( add 40 to both sides )
3x = 48 ( divide both sides by 3 )
x = 16 → C
