To biil customers for water usage, one city converts the number of gallons used into units. This relationship is represented by

Finger [1]

The answer to this question would be:
<span>B.) u is the dependent variable.
</span>
In this case, the gallon is converted into unit which means the number of gallons is fixed(got from the customer water usage) but the number of units depends on the number of the gallon(748unit for every gallon). That is why "unit" become the dependent variable and "gallon" become the independent variable.

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph. Select from the drop-down menus to correctly co

rodikova [14]

Answer

The speedometer is likely to show the speed is either 36.0 mph or 44.0 mph.

To prove

Formula

$Percentage\ error = \frac{error\times 100}{Exact\ value}$

Where error = |Approx value - Exact value |

First case

As given

A speedometer has a percent error of 10%. The actual speed of the car is 40 mph.

Here

Percentage error = 10%

Exact value = 40 mph

error = - (Approx value - Exact value )

= - (Approx value - 40 )

= - Approx value + 40

Put in the formula

$10 = \frac{(-Approx\ value + 40)\times 100}{40}$

$400 = {(-Approx\ value + 40)\times 100}$

$\frac{400}{100} =-Approx\ value + 40$

$\4 =-Approx\ value + 40$

Thus

Approx value = 40 - 4

Approx value = 36 mph

Therefore Option (b) is correct .

Second Case

error = (Approx value - Exact value )

= (Approx value - 40 )

= Approx value - 40

Put in the formula

$10 = \frac{(Approx\ value - 40)\times 100}{40}$

$400 = {(Approx\ value - 40)\times 100}$

$\frac{400}{100} = Approx\ value - 40$

$\4 = Approx\ value - 40$

Thus

Approx value = 40 + 4

Approx value = 44 mph

Therefore Option (c) is correct .

In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

grandymaker [24]

The right answer for the question that is being asked and shown above is that: In the function f(x) = 4(x2 − 6x + ____) + 20, what number belongs in the blank to complete the square?

x2 - 6x + 9

So the answer on the blank space is 9. It should be a perfect square.
= 6/2
= 3^2
= 9

Try to simplify 72/6+85/6

Reil [10]

72/6+ 85/6
= (72+ 85)/6
= 157/6
= (156+1)/ 6
= 156/6+ 1/6
= 26+ 1/6
= 26 1/6

The final answer is 26 1/6~
