Answer:

The wedding planner must have purchased 28 small lanterns and 12 large lanterns.

Step-by-step explanation:

Let the number of small and large lanterns purchased be S and L respectively.

S + L = 40  ........ Equation 1

L = 40 - S

25S + 40L = 1180  ....... Equation 2

25S + 40(40 - S) = 1180

25S + 1600 - 40S = 1180

-15S = 1180 - 1600

-15S = -420

S = 28

L = 40 - S

L = 40 - 28

L = 12

The wedding planner must have purchased 28 small lanterns and 12 large lanterns.

Answer: y=12 x=28

Explanation:
x=Amount of Small Lanterns y=Amount of Large Lanterns
25x+40y=1180
x+y=40
x=40-y
25(40-y)+40y=1180
1000-25y+40y=1180
1000+15y=1180
15y=180
y=12
x+12=40
x=28

A hyperbola centered at the origin has a vertex at (0, 36) and a focus at (0, 39).
likoan [24]
To solve this problem you must apply the proccedure shown below:
 1. You have that the hyperbola <span>has a vertex at (0,36) and a focus at (0,39).
 2. Therefore, the equation of the directrices is:

 a=36
 a^2=1296
 c=39

 y=a^2/c

 3. When you susbtitute the values of a^2 and c into </span>y=a^2/c, you obtain:
<span>
 </span>y=a^2/c
<span> y=1296/13

 4. When you simplify:

 y=432/13

 Therefore, the answer is: </span><span>y = ±432/13</span>
