What is the percentage of growth? in the first quarter of 2010, u. s. advertisers spent $5.9 billion on online advertising. in the first quarter of 2011, they spent $7.3 billion. what is the percentage rate of growth? (round to one percentage place.)

24%

Percentage change is computed as follows. When it is positive, it represents growth or increase. When it is negative, it represents decrease or decline.

... percent change = ((new value) - (old value))/(old value) × 100%

... = (7.3 -5.9)/5.9 × 100%

... = 1.4/5.9 × 100%

... ≈ 0.2373 × 100%

... ≈ 24% . . . . . rounded to nearest whole percent

Since the time difference is 1 year, this is the annual growth rate.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

you probably already have the answer but anyways it's b. 15.0
