Christie sells lemonade in her driveway she spends $20 dollars on supplies lemons sugar and cups she can make enough lemonade fo
Rasek [7]

Answer:

Profit = $ 5

Step-by-step explanation:

Money spent on supplies = $ 20

Number of cups of lemonade sold by her = 100

Selling price for 1 cup of lemonade = 1 quarter = $ 0.25

∴ Selling price for 100 cups of lemonade = 0.25\times100=25

So, Christie can make $ 25 from 100 cups of lemonade.

Profit made by her = Selling price - Money spent on supplied

                                 = $ 25 - $ 20 = $ 5.

PLZ EXPLAIN , I WANT TO KNOW HOW TO DO
Phantasy [73]
Make sure you know the formula pertaining to the question. 

1. c=2(pi)(r)
2. c=2(pi)(d)

r= radius 
d= diameter
c= sircumference

So we are given that the circumference of a circle is 12.3pi and the radius is unknown. 

So let's plug in the known values 

**we use the formula with the radius, becuase we are looking for the radius. 

c=2(pi)(r)
12.3(pi)=2(pi)(r)

divide each side by pi

12.3=2(r)

divide each side by 2

r=6.15 in.

Write an explicit formula for a_na
Masja [62]

Explicit formula for the sequence 29,20,11....... is a_n=38-9n

Given :

term of the sequence 29, 20, 11, ...

We need to find out the formula for the nth term of the given sequence

Lets find out whether the given sequence is arithmetic or geometric

In the given sequence , common difference is 9

20-29=-9\\11-20=-9

we can say difference =-9

General explicit formula

a_n=a_1+(n-1)d

where a1 is the first term

common difference d=-9

substitute the values

a_n=a_1+(n-1)d\\a_n=29+(n-1)(-9)\\a_n=29-9n+9\\a_n=38-9n

Explicit formula for the sequence 29,20,11....... is a_n=38-9n
