Suppose a lake contains blue and green algae. The blue algae has an initial mass of 20 kg and doubles its mass every hour. The g
loris [4]

Answer:  1) D

2) C

Step-by-step explanation:

1. The blue algae has an initial mass of 20 kg and doubles its mass every hour. Then after t hours, the mass of blue algae is

2. The green algae has an initial mass of 160 kg and grows at a constant rate of 0.20 kg per minute. Then after t hours (60t minutes), the mass of green algae is

Part I) At t=3:

The mass of green algae has 196-160=36 kg more mass at 3 hours.

Part II) At t=4:

The blue algae has 320-208=112 kg more mass at 4 hours.

F(x) = 3x + 1; g(x) = 5x - 1<br> Find f/g. (1 point)
zysi [14]

Answer:

\frac{f}{g} =\frac{3x+1}{5x-1}

x\neq \frac{1}{5}

Step-by-step explanation:

we are given

f(x)=3x+1

g(x)=5x-1

we have to find f/g

we can write as

\frac{f}{g} =\frac{f(x)}{g(x)}

now, we can plug values

and we get

\frac{f(x)}{g(x)} =\frac{3x+1}{5x-1}

so,

\frac{f}{g} =\frac{3x+1}{5x-1}

we know that denominator can not be zero

so,

5x-1\neq 0

now, we can solve for x

5x-1+1\neq 0+1

5x\neq 1

Divide both sides by 5

and we get

x\neq \frac{1}{5}

Help please i really really really need it.....
ruslelena [56]

A)

s = sweater

j = jeans

Equations:

4s + 2j = 140

2s + 3j = 150

B)

4s + 2j = 140

2s + 3j = 150

Multiply (-2) to the second equation

-2 (2s + 3j = 150)

-4s - 6j = -300

Now you have the equations:

4s + 2j = 140

-4s - 6j = -300

-----------------------------add

-4j = -160

  j = 40

4s + 2(40) = 140

4s + 80 = 140

4s = 60

 s = 15

The cost for a sweater is $15 and the cost for a jean is $40

We used the elimination method to solve the system of equations.

C)

Each pair of jean, she will buy 3 sweaters so total = 40 + 3(15) = $85

Total cost for 1 pair of jeans and 3 sweaters = $85

If she has $225 the

$225 / $85 = 2.64

2 jeans = 2 x 40 = $80

6 sweaters = 6 x $15 = $90

So She can only buy 2 jeans and 6 sweaters

A store charges a restocking fee for any returned item based upon the item price. An item priced at $200 has a fee of $12. An it
lyudmila [28]

Answer:

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.

Step-by-step explanation:

For the $200, the restocking fee is $12, so the ratio of the restocking fee to the price of the item is 12/200.

For the $150, the restocking fee is $9, so the ratio of the restocking fee to the price of the item is 9/150.

Now we find out if the ratios 12/200 and 9/150 are equal.

12/200 = 3/50

9/150 = 3/50

Both ratios reduce to the same ratio 3/50, so the restocking fee is proportional.
