-12 divided by 3 x (-8 + (-4) ^2 - 6) + 2

riadik2000 [5.3K]

Answer:

-3/2

Step-by-step explanation:

Here we have an ambiguous notation. Hence, I assume you mean (-12/((3 x (-8+ (-4)^2 -6) +2), which is the one that makes more sense.

First, we work the arithmetic on the denominator (D).

D= 3 x (-8 + (-4)^2 - 6) + 2

D=3 x (-8 + (-4) x (-4) -6) + 2

D= 3x (-8 +16 -6) + 2

D= 3 x (2) + 2=6 + 2=8

Now, we just have to divide -12 by D to obtain the answer.

-12/D = -12/8 =(-2 x 2 x 3)/(2 x 2 x 2) = -3/2

It took 48 minutes to drive downtown. An app estimated it would be less than that. If the error was 20%, what was the app’s esti

IgorLugansk [536]

Answer:

The estimated taken to drive downtown using App is 38.4 minutes

Step-by-step explanation:

Given as :

The initial time taken to drive downtown = i = 48 minutes

The percentage error of time = r = 20%

Let The estimated time using app = t min

Let the time = 1 min

<u>Now, according to question</u>

The estimated time using app = The initial time taken to drive downtown × $(1-\dfrac{\textrm rate}{100})^{\textrm time}$

Or, t minutes = i minutes × $(1-\dfrac{\textrm r}{100})^{\textrm 1}$

Or, t = 48 minutes × $(1-\dfrac{\textrm 20}{100})^{\textrm 1}$

Or, t = 48 minutes × $\dfrac{100-20}{100}$

Or, t = 48 minutes × $\dfrac{80}{100}$

∴ t = $\dfrac{48\times 80}{100}$ minutes

I.e t = 38.4 minutes

Or, The estimated time using app = t = 38.4 min

Hence, The estimated taken to drive downtown using App is 38.4 minutes Answer
