Assume the following sales data for a company: Current year $325,000
Preceding year 250,000

What is the percentage increase in sales from the preceding year to the current year?

a. 70%
b. 30%
c. 50%
d. 76.9%

b. 30%

Explanation:

The computation of the percentage increased in sales from the previous year to the current year is shown below:

= (Current year Sale - Preceding year Sale) ÷ (Preceding year Sale )

= ($325,000 - $250,000) ÷ ($250,000)

= ($75,000) ÷ ($250,000)

= 30%

Hence, the correct option is b. 30%

We simply applied the above formula to determine the percentage increased in sales

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
