Answer:
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.
The specific heat of the gold is 1.67 (=125/(3*(43-18)) joule/ gram oC based on its heat energy, change in temperature and mass. This problem can be solved using the heat energy formula which stated as Q=c*m*(deltaT). In this formula, Q is the heat energy, c is the specific heat, m is the object's mass, and deltaT is the change in the temperature of the reaction<span>.</span>
