If a faucet leaks 7 oz of water per minute, how many gallons of water are wasted in a year? (128 oz/gallon)
blagie [28]

Well, how many minutes are there in a year? It would be way too easy to  say "too many".

First, we calculate minutes in a day, which is 60 x 24 (minutes in an hour x number of hour)

This equals 1440. There are 365 days in a year, so we multiply 365 by 1440, which equals 525,600

The conversion of oz to gallon occurs, and bigger units mean division since their capacity makes the necessity for them significantly smaller; we divide 525600 by 128, and we get 4106.25.

4106.25 gallons of water are wasted in a year

Find the measure of angle AEC.​
Anon25 [30]

Answer:

∠ AEC = 49°

Step-by-step explanation:

the sum of the angles in Δ ACE = 180° , that is

∠ AEC + 90° + 41° = 180°

∠ AEC + 131° = 180° ( subtract 131° from both sides )

∠ AEC = 49°

Write a quadratic equation with integer coefficients and the given numbers as solutions.
adoni [48]

Answer:

1.)  f(x) = x*x - 7x + 10

2.) f(x) = x*x - 5x

3.) f(x) = 4*x*x - 5x - 6

4.) f(x) = 6*x*x -5x + 1

Step-by-step explanation:

1.)  2 and 5     (x -2)(x - 5) = f(x)  =  x*x - 7x + 10

2.)  0 and 5     f(x) = x*(x -5) =  x*x - 5x

3.) -3/4  and 2     (x + 3/4)(x -2) = x*x - (5/4) x - 3/2,

 need integers   f(x) = 4xx - 5x - 6

4.) 1/2  and 1/3    (x - 1/2)(x - 1/3) = f(x)

 x*x  - 1/3 x  - 1/2 x +  1/6  

xx  -  5/6  x  + 1/6

6 xx - 5x  + 1
