Answer:
The biggest difference is between fruit juice and lemonade ($0.6).
Step-by-step explanation:
Giving the following information:
items:
fruit juice. $0.89
iced tea. $1.29
lemonade. $1.49
pretzel. $2.50
popcorn. $1.25
First, popcorn and pretzel are not beverages.
<u>Now, we need to find the differences in prices between each beverage and determine the greatest:</u>
Fruit juice to ice tea= 0.89 - $0.4
Fruit juice to lemonade= 0.89 - 1.49= $0.6
Ice tea to lemonade= 1.29 - 1.49= $0.2
The biggest difference is between fruit juice and lemonade ($0.6).
Subtract 3 from both sides so that the equation becomes -2x^2 + 5x - 13 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √((5)^2 - 4(-2)(-13)) ] / ( 2(-2) )
x = [-5 ± √(25 - (104) ) ] / ( -4 )
x = [-5 ± √(-79) ] / ( -4)
Since √-79 is nonreal, the answer to this question is that there are no real solutions.
Answer:
0.000462
Step-by-step explanation:
From the given information:
The cotton count of the piled yarn is the ratio of the simple weight in (g) with the length by the simple length with weight.
Mathematically:
Using the function 2*1/2^3t given, it is just to input the value given to the function.
Or in other words, replace the letter, with the number.
Like this
F(2) = 2*1/2^3*2
F(2) = 2*1/2^6
F(2) = 2*1/64
F(2) = 2/64 = 1/32
1/32 is the answer.
If your formatting was correct. :)
