Each time Henry visits the art museum he pays $15 for parking and $25 for admission.
irina [24]

For this case we have to:

x: Variable that represents the number of times Henry visits the art museum.

If you pay 15 for parking and 25 for admission every time you go, we have:

(15 + 25) x = 40x

Now, if you buy a membership at a net cost (it does not depend on the number of visits to the museum) of $ 110 and only pay $ 10 of parking, every time you attend the museum, we have:

110 + 10x

Finally, the two equations that represent the situation are:

40x; 110 + 10x

Answer:

Option A

A theater is selling movie tickets. The first night, 19 Senior tickets and 57 Adult tickets were sold. The second night, 20 Seni
Butoxors [25]

Answer:

The theater sold a higher ratio of Senior tickets to Adult tickets on the first night.

Step-by-step explanation:

Rate of senior tickets to adult tickets:

Can also be interpreted as the percentage of senior tickets, out of the number of total tickets, which is the number of senior tickets multiplied by 100% and divided by the number of total tickets.

The first night, 19 Senior tickets and 57 Adult tickets were sold.

19 out of 19 + 57 = 76. So

19*100%/76 = 25%

The second night, 20 Senior tickets and 62 Adult tickets were sold.

20 out of 20 + 62 = 82. So

20*100%/82 = 24.39%

25% > 24.39%, so the theater sold a higher ratio of Senior tickets to Adult tickets on the first night.

. A regular hexagon is composed of 12 congruent 30 o -60 o -90 o triangles. If the length of the hypotenuse of one of those tria
sergey [27]

see  the attached figure to better understand the problem

Let

2L---------> lenght side of hexagon


we know that

in one of those triangles

sin 30=1/2

sin 30=L/hypotenuse

solve for L

L=hypotenuse*sin 30-------->L=( 1 8 √ 3 )*(1 /2)------> L=9√3 units


Find the perimeter

perimeter=(2L)*6--------> L*12-------> Perimeter=9√3*12--------->108√3 units


therefore


the answer is

the perimeter of the regular hexagon is 108√3 units
