Answer:

y = 9 - 1.75x

Step-by-step explanation:

Given

Initial\ Height = 9ft

Rate = 1.75ft per hour

Required:

Determine the linear function

Let y represent the function and x represent the number of hours

The function can be represented with:

y = Initial\ Height- Rate * x

We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.

So, we have:

y = 9 - 1.75 * x

y = 9 - 1.75x

When p = 12, t = 2, and s = 1/6, r = 18. If r varies directly with p and inversely with the product of s and t, what is the cons
Ilia_Sergeevich [38]
R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k

Suppose the movie theater you work at sells popcorn I'm three different sizes. A small cost $2, a medium cost $5, and a large co
VMariaS [17]

Let, number of small, medium and large popcorn sold are s, m and l respectively.

So, s + m + l = 250    ....1)

Also, l = 2s     ....2)

Total sum = $1726 = 2s + 5m + 10l     .....3)

Putting value of l from 2) to 1) is :

s + m + 2s = 250

m + 3s = 250    

m = 250 - 3s      ....4)

Putting value of m and l in terms of s in equation 3)

We get :

2s + 5( 250 - 3s ) + 20s = 1726

7s = 1726 - 1250

s = 68

l = 136

m = 250 -3(68) = 46

Now,

P_s=68\times 2 = \$136\\\\P_m = 46\times 5 = \$230\\\\P_l = 136\times 10 = \$1360

Hence, this is the required solution.
