One cup equals approximately 236 ml. Approximately how many ml are there in one gallon
GREYUIT [131]

Answer:

<u>Approximately there are 3,785.6 milliliters in one gallon </u>

Step-by-step explanation:

Let's find out how many milliliters are there in one gallon.

1 US Cup = 236.6 ml (actual equivalence)

Let's recall that:

16 US Cups = 1 US Gallon

Therefore,

1 US Gallon = 16 * 236.6 ml

1 US Gallon = 3,785.6 ml

<u>Approximately there are 3,785.6 milliliters in one gallon</u>

How to solve x^2+x-90=0 in completing the square method​
tigry1 [53]

Rearrange the equation by writing

x² + x - 90 = 0

x² + x = 90

x² + x + 1/4 = 90 + 1/4

Recall that (a + b)² = a² + 2ab + b². Then

x² + 2 • x/2 + (1/2)² = 361/4

(x + 1/2)² = 361/4

x + 1/2 = ± √(361/4)

x = -1/2 ± 19/2

x = 9   or   x = -10
