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.

Mia found the area of a polygon The area is 32 square cm.

solniwko [45]

Answer:

Only the isosceles trapezoid has an area of 32 cm².

Step-by-step explanation:

Let's calculate the area of each polygon.

For the two triangles we have:

$A_{t} = \frac{bh}{2} = \frac{2 cm*4 cm}{2} = 4 cm^{2}$

This polygon does not have an area of 32 cm².

For the rectangle we have:

$A_{r} = bh = 6 cm*4 cm = 24 cm^{2}$

This polygon does not have an area of 32 cm².

For the rectangle trapezoid we have:

$A_{rt} = A_{t} + A_{r} = (4 + 24) cm^{2} = 28 cm^{2}$

So, this polygon does not have an area of 32 cm².

Finally, for the isosceles trapezoid:

$A_{it} = A_{t}*2 + A_{r} = (4*2 + 24) cm^{2} = 32 cm^{2}$

This polygon does have an area of 32 cm².

Therefore, only the isosceles trapezoid has an area of 32 cm².

I hope it helps you!
