The startup division made 80% of 1/2 of the established division. The startup division’s growth was 1/3 greater than the establi

Gnesinka [82]

Answer:

Step-by-step explanation:

First, let's create variables:

s = startup division

e = established divisioN

The startup division made 80% of 1/2 of the established division.

Let's take a look at what the above statement means: Making 80% of 1/2 means...

0.8 of 1/2 = 0.8*0.5 = 0.4 --> s = 0.4e.

Next: The startup division’s growth was 1/3 greater than the established division’s.

Seems like this is additional information is not needed.

If the divisions made 280,000 combined, how much did the startup division make?

s + e = 280,000 --> s = 280,000 - e, then we can substitude s = 0.4e for s -->

280,000 - e = 0.4e --> 1.4e = 280,000 --> e = 200,000.

This means that s = 80,000.

Alecsey [184]

Answer:201 students

Step-by-step explanation: Since there are seven kids riding in cars, you would subtract 7 from 1213 to get 1206 students. The six buses means you divide by 6 to get 201 students in each bus.

A 12,000-lb killer whale might eat as much as 14,000 lb of fish per month (assume a 30-day month). If the average weight of a ce

brilliants [131]

Answer:

2196 fish

Step-by-step explanation:

Weight of fish that the killer whale might eat in a month (30 days) = 14,000 lb

Weight of the fish that killer whale might eat in a day = $\frac{14000}{30} = \frac{1400}{3}$ lb.

Average weight of the fish that killer whale eats = 3.4 oz

Since,

1 pound(lb) = 16 ounces(oz)

So,

Weight of the fish that killer whale might eat in a day in ounces(oz) = $\frac{1400}{3} \times 16=\frac{22400}{3}$ oz

Since, a certain fish weighs 3.4 oz, in order to find the number of fish that killer whale must eat, we must divide the total weight in ounces by 3.4 ounces.

So, the number of fish that killer whale would eat = $\frac{22400}{3} \div 3.4 = 2196$ fish
