Answer:

Don caught 3.6 kg and Dan caught 0.6 kg.

Step-by-step explanation:

Set up a system of equations:

Don's fish is the variable a and Dan's fish is the variable b.

a + b = 4.2 (1)

a=6b          (2)

We can substitute a in the first equation using the second equation, so:

6b + b = 4.2

7b = 4.2

b = 0.6 kg

Dan caught 0.6 kg. Then, we can use equation 2 to find how much Don caught.

a = 6 x 0.6

a = 3.6

Don caught 3.6 kg.

Please help and thank you

Answer:

D) 130 workers

Step-by-step explanation:

We have the equation, <em>y = 2x + 40</em>, and <em>y, 300</em> (since the y-coordinate represents the # of bottles made), so we can solve for x, <em>the number of workers needed</em>.

Substitute: <em>300 = 2x + 40</em>

Subtract: <em>260 = 2x</em>

Divide: <em>x = 130</em>

Since x = 130 when y = 300, 130 workers are required to make 300 bottles in a day.

the population of the state of colorado was about 5,030,000 people in 2013 which number best approximates the population as a si
PIT_PIT [208]

Answer:

5 • 10^6

Step-by-step explanation:

When we talk about approximations, it is important to know that their purpose is not to find the correct value, only close enough that will do the job. We use them when we want to write something in a shortened way, to save time or when it's impossible to find precise value. Of course, our approximation won't be 100% precise, but it will be acceptable.

So, in this case, we are dealing with a population that is just above five million.

Milion (1 000 000) is a seven-digit number written with six zeros, so its power of ten will be 10^6 (ten to the power of six).

Since the population is around five million, we will approximate it to  

5 • 10^6 (five times ten to the power of six)
