Answer:
110 yards of string
Step-by-step explanation:
Converting the feet of the string of 1 balloon to yard
1 foot = 1/3 yard
6 feet = x
x = 6 × 1/3 yard
x = 2 yard
Hence 1 balloon uses 2 yard of string
Since:
1 balloon = 2 yard of string
55 ballons = x
x = 55 × 2 yard of string
x = 110 yards of string
Hence, for 55 balloons he would need 110 yards of string.
Okay well the starting is 28 dollars, right. But since there is a 20 percent discount, you have to turn 20% to a decimal. That means moving the decimal sign twice to the left to make it .20. From the it would be .20*28, that should equal 5.6. Now, that 5.6 is the amount you have to take away, it is the price of the sale. From then, you subtract which is 28-5.6 which should be 22.4. From that 22.4 you now take away two dollars and then it should be 22.4-2 which should be 20.4. Now that is your answer, 20.4.
The cost of one book = $ 6 7
Number of books = 1 0 2
The cost of 102 books = $ 67 × 102
= $ 6834
Therefore, cost of 102 books = $ 6834
There total revenue was like 7k or something
Answer: See below.
Step-by-step explanation:
The formatting is likely incorrect for these two options:
y=(x−1)2, and
y = ( x − − 1 ) 2
I'll assume they were meant to be:
y=(x−1)^2, and
y = ( x + 1 )^2
In this case they would be non-linear, since y depends on the value of 
Use a "^" sign to indicate raised to a power: x^2 means .
y=(x−1)2 means y = 2x - 2
y=(x−1)^2 means y =
