Answer:
1$/2.5lb
Step-by-step explanation:
This is a fraction equal to 5 pounds / 2 dollars
We want a unit rate where 1 is in the denominator, so we have to divide the top and bottom by 2.
5 pounds / 2
2 dollars / 2
This should progress to
2.5 pounds/a dollar
This means that the unit rate is 2.5 pounds per dollar.
Answer:
(2b - 3)(2b + 3)(b - 3)
Step-by-step explanation:
4b³ - 9b - 12b² + 27
b(4b² - 9) - 3(4b² - 9)
(4b² - 9)(b - 3)
(2b - 3)(2b + 3)(b - 3)
The y intercept is the point where x = 0 on the line.
When x = 0, y will equal 5.
y - intercept = (0,5)
The question involves what is referred to as a mass balance and can be solved as follows:
Ink A is:
total = 4ml
blue = 4 x 0.1 = 0.4ml
remaining = 3.6ml
Ink B is:
total = 10ml
blue = x
Remaining = 10 - x
Now, upon combination:
total = 4ml + 10ml = 14ml
Blue = 14ml * 0.35 = 4.9ml
Blue in total = blue in A + blue in B
4.9 = 0.4 + x
x = 4.5ml
Percentage of blue ink in B = 4.5/10 x 100
= 45%
The answer is A
