Step-by-step explanation:

Let's get the constant (k) first.

Now, let's find q when r=1.6 and s=.01.

no1. if i'm not mistaken k=1/15 while a=18/5

Step-by-step explanation: follow the equation a=kbc

Okay kinda guessing you're a Lasallian student becoz we have the same quiz hmM u grade 9 peeps I think so

80

Step-by-step explanation:

If q varies jointly as r and s, then we know that the following equation is true:

where k is a certain constant.

Rearranging the equation, we get:

First, we need to solve for k. Then, we'll use that to solve for the new q.

The following series of equations will display and explain the full solution to solve for q.

k = (60) / (3)(4)

k = 60 / 12

k = 5

q = (5)(2)(8)

q = (10)(8)

q = 80

Thus, the value of the new q must be 80.

Hope this helps!

Step-by-step explanation:

3. If q varies jointly as r and s, and q = 60 when r=3 and s = 5. Find q when r=7 and s=2

4. If y varies directly as x and inversely as the square z, and y = 4 when x = 12 and z= 3.find z when

9 and x = 75.

First find k:

If q varies jointly as r and s, the formation should be:

q = krs                                                         q=24

24= k(6)(8)                                                    r=6

24= 48k                                                        s=8

24/48 = k

1/2= k or k= 1/2

Then proceed to the problem:

k=1/2

r=16

s=8

q=?

q=krs

q=(1/2)(16)(10)

q=80
