2(10.7r - 9.5) = 33.8 rounded to the nearest tenth

Vikentia [17]

2(10.7r - 9.5) = 33.8

10.7r
this means the number is times a variable.

10.7r - 9.5 = 1.2r

2 x 1.2r = 33.8, so we need to find the value of the variable for 1.2r

the variable that makes sense to me would be approx.14.085, so 1.2r x 2 = approximately 33.8 if you round 14.085 to the nearest tenth.

so I would say it is 14.1. hope I helped you :)

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 .
