Agarden store is purchasing iris bulbs to sell for spring planting. each year the store sells two varieties of iris bulbs. purple and yellow. last year, the store sold 260 yellow iris bulbs. the store manager noted that the ratio of yellow to total iris bulbs sold was 2: 5. how many purple iris bulbs were sold

390

Step-by-step explanation:

Only two varieties are involved: yellow and purple.

We know the ratio of yellow iris bulbs over the total is 2:5, so 40%.

That leaves 60% of the sales for the purple bulbs.

purple = (60% / 40%) * 260 = 1.5 * 260 = 390.

So, they sold 1.5 times more purple bulbs than yellow ones.

In total, the store sold 650 bulbs last year, and we hope they sell more this year.

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
