<span>No. Since the atom has 31 protons, that means it's an isotope of gallium. Looking up gallium, you can determine that in nature it's composed of the two stable isotopes, gallium-69 and gallium-71, which have 38 and 40 neutrons respectively. Looking further, you will find that gallium-62 has a half life of 116.18 milliseconds which means it's quite unstable.</span>

Answer: $690

Explanation:

The 2018 year- end adjusted balance of Salaries Payable will be calculated as:

= $0 + $690

= $690

Note: Salaries accrued at December 31, 2018 will be:

erik [133]

Answer:

b. The cable commercial

Explanation:

CPM or cost per mille is a measure used in advertising to determine how effectively a promotional message is getting to its audience. It is the cost of getting an advert in front of 1,000 people.

In this scenario when we calculate CPM for the radio station

$600 = 10,250 listeners

x= 1,000 listeners

Cross multiply

x= (600 * 1,000) ÷ 10,250 = $58.54

For the local cable commercial

$1000 = 18,500 viewers

y = 1,000 viewers

Cross multiply

y= (1,000 * 1,000) ÷ 18,500= $54.05
