<h3>Answer: Choice C</h3>

Reason:

k = constant of proportionality

The value of k is determined by the formula

k = y/x

Let's say we picked the first row of table C

k = y/x

k = 3/18

k = 1/6

You should get the same k value for the other rows of this table. Treat the mixed number 4 1/2 as 4.5, if you prefer.

John is at a local bait shop; he wants to buy bait for his fishing trip. At the store, they are selling love bait for $12 a poun
Scrat [10]

Answer:

  1. 12x+7y\le 63
  2. x\ge 3

Step-by-step explanation:

Let us assume that, x be the amount of live bait and y be the amount of natural bait.

The price of live bait is $12 per pound and that of the natural bait is $7 per pound.

As John has a budget of $63, so he spend any amount less than or equal to $63, not more than that. So the inequality for this will be,

12x+7y\le 63

John would like to get at least 3 pounds of live bait, so the inequality for this will be,

x\ge 3

A spherical party balloon is being inflated with helium pumped in at a rate of 10 cubic feet per minute. How fast is the radius
Anastaziya [24]

Answer:

The radius is growing at a rate of   \frac{dr}{dt}  = \frac{10}{4 \pi} = 0.795 ft per minute.

Step-by-step explanation:

From the information given we know that

\frac{dV}{dt} = 10

And we know as well that .

V = \frac{4}{3} \pi r^3

Since everything is changing with the time we can compute the implicit  derivative and we would get that

\frac{dV}{dt} = 10 = 4\pi r^2 \frac{dr}{dt}

We are told that we are looking for how fast is the radius growing at the instant when the radius has reached 1 ft, therefore  r = 1.

And when we solve for  \frac{dr}{dt}  = \frac{10}{4 \pi} = 0.795
