Answer:
1 Adult ticket=$35
1 Children ticket=$20
Step-by-step explanation:
21C+15A=945
6C+6A=330
we find adult tickets first
42C+30A=1890
42C+42A=2310
12A=420
A=35
we will find children ticket next
42c+30a=1890
30c+30a=1650
12c=240
C=20

Answer:
The question is:
The following function, L, gives the approximate percent literacy rate in India t years after 1900.
L(t)=5.3 x 1.025^t
Which of the following equivalent functions shows, as a constant or coefficient, the approximate number of years it took for the literacy rate to triple?
(a) L(t)=5.3 x 3^t/44.5
(b) L(t)=5.3 x 1.077^t/3
(c) L(t)=5.3 x 1.008^3t
(d) L(t)=3 x 1.025^t+23
Explanation:
The ability of Anthony to be able to smell the gas in his house because of the activation of his olfactory receptors through the process of sensation.
<h3>What is olfactory system?</h3>
The olfactory system refers to the sense of smell. Human being feel the sensation of smell through the nose. The nose is the organ of the body responsible for perceiving both good and bad odor.
There are five major sense organs in the body:
- Eyes - Sight
- Nose - Smell
- Tongue - Taste
- Skin - Touch
- Ears - Hearing

Answer:
Krypton is a noble gas, so it was difficult for chemists to find it, as though it was a secret.
Explanation:
Krypton (₃₆Kr), an element with atomic number 36, belongs to group 18 on the periodic table of elements. This group is a specific one - it's made up of elements known as noble gases. Besides krypton, these elements are: helium, neon, argon, xenon, and radon. All noble gases were characterized relatively late compared to other elements. They all conduct electricity, fluoresce, and are odorless and colorless. Besides that, they have very low chemical reactivity. Because of their stability, they are often used to maintain a safe, constant environment. As krypton shares all of these characteristics, it was difficult for chemists to find it. That's why it was most likely given that name.
Sin(30°) =1/2 0.5
cos(30°) = (√3)/2
Note that the sin of an angle is equal to the cos of the complementary angle:
sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)
