Answer:
Step-by-step explanation:
Original price $595.00
Discount amount 595(0.30) = $178.50
Pre tax price 595.00 - 178.50 = $416.50
tax amount 416.50(0.07) = 29.155 = $29.16
cost to Victoria 416.50 + 29.16 = $445.66

THIS IS THE MEAN OF GIVEN DATA.
Answer:
y = 14
Step-by-step explanation:
Since AC = BC then the triangle is isosceles and the base angles are congruent, that is
∠A = ∠B = 50°, thus
∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°
= 180 - 100 = 80°, hence
5y + 10 = 80 ( subtract 10 from both sides )
5y = 70 ( divide both sides by 5 )
y = 14

I hope that's right I'm not too sure lol
Answer:
A/C
Step-by-step explanation:
Since the sum of the angles in a triangle equals 180°, and angle C is 90°.
That means angles A and B add up to 90°, that is, they are complementary angles. Therefore the cosine of B equals the sine of A.
We saw on the last page that sin A was the opposite side over the hypotenuse, that is, a/c. Hence, cos B equals a/c.
Your welcome! :)
