It took 48 minutes to drive downtown An app estimated it would be less than that If the error was 20% what was the apps estimate

Zina [86]

Answer:

The app's estimate was 38.4 minutes.

Step-by-step explanation:

Suppose, the app's estimated time was $t$ minutes.

Given that, it took 48 minutes to drive downtown. So, the error in estimated time by the app $=(48-t)$ minutes.

It is also given that the error was 20%. So, the amount of error $= (48*0.20)=9.6$ minutes.

Thus, the equation will be......

$48-t= 9.6\\ \\ -t=9.6-48\\ \\ -t=-38.4\\ \\ t= 38.4$

So, the app's estimate was 38.4 minutes.

The low temperature on Monday was 16°F. On Tuesday, the low was 18°F cooler. On Wednesday, the low temperature was –4 times Tues

drek231 [11]

Answer:

$-4(16-18)$ , $[16 + (-18)](-4)$

Step-by-step explanation:

Given: The low temperature on Monday was 16°F. The low temperature on Tuesday was 18°F cooler. The low temperature on Wednesday was –4 times Tuesday’s temperature.

To find: expression that can be used to describe the low temperature on Wednesday

Solution:

Temperature on Monday = 16°F

So,

Temperature on Tuesday = $(16-18)\°F$

Temperature on Wednesday = $-4(16-18)\°F$

So, expression $-4(16-18)=(16-18)(-4)$ can be used to describe the low temperature on Wednesday.

Also,

$(16-18)(-4)=[16 + (-18)](-4)\,\,\left \{\because (a-b)=\left [ a+(-b) \right ] \right \}$

So, expression $[16 + (-18)](-4)$ also represent temperature on Wednesday.
