In the US, a pint is 16 fluid ounces and a quart is 2 pints. So, every quart will fill 2 coffee mugs.
Annie needs to fill 26 mugs, and she needs 1 quart for every 2 mugs. So Annie needs 13 quarts of coffee total.
Answer:
factorisation method
4x² - 3x + 9 = 2x + 1
4x² - 3x-2x +9-1 = 0
4x² - 5x + 8 = 0
sum = -5
product= 4x8
32
factors=(try to look for the numbers when added they give -5 a!d when multiplied they give 32
press the numbers in the position of -5
factorise
each blacket equal it to 0
and solve for the two values of x
Y=4^4-100=16-100=-84
Result is -84
It’s 7 because you round it
Explanation
The model has the form
Where a=initial amount
y= final amount
K= growth rate constant
t= time
When 140 kg of substance is left after 7 hours, the formula can be remodeled to be.
Therefore, the first solution is
For part b we have 16 hours.
Thus, the answer is 36kg
