Answer:

adult: $5
student: $15

Step-by-step explanation:

If we let 'a' represent the price of an adult ticket, and 's' represent the price of a student ticket, the two sales can be described by ...

5a +4s = 85

5a +2s = 55

Subtracting the second equation from the first gives ...

(5a +4s) -(5a +2s) = (85) -(55)

2s = 30 . . . . simplify

s = 15 . . . . divide by 2

Substituting this into the second equation, we have ...

5a +2(15) = 55

5a = 25 . . . . subtract 30

a = 5 . . . . . divide by 5

Each adult ticket sold for $5; each student ticket sold for $15.

For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is need

jasenka [17]

Diameter is 2.36 cm.

Given:
Circumference = 7.38 cm

Circumference of a circle is computed by multiplying 2, pi, and its radius.

C = 2πr

7.38 = 2 (3.14) r
7.38 = 6.28r
7.38/6.28 = 6.28r/6.28
1.18 = radius

Diameter = 2r
Diameter = 2(1.18)
Diameter = 2.36 cm

Answer:

After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

Step-by-step explanation:

Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:

1/2 ^ 6 = X

0.015625 = X

1/64 = X

1/2 ^ 28 = X

0.0000000037252902984619140625 = X

1/268435456 = X

Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 o

Arlecino [84]

Answer:

The population is all 600 members of the health club

Explanation:

50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.
