340.34

Step-by-step explanation:

67.27

Step-by-step explanation:

7.1 x 7.1 for the square = 50.41

7.1 divided by 2 = 3.55

3.55 x 4.75= 16.86

Normally here you would divide by 2, but you don’t need two because there is 2 triangles that are the same

Add the 50.41 and the 16.86 and you have your answer!

Step-by-step explanation:

I would say it’s (0,-2) for the answer.

Step-by-step explanation:

-1, 0, 2, 4 1/4        the last 4 numbers

Step-by-step explanation:

everything that is greater than -2

-19=-2/3x

3*-19=-2x

-57=-2x

-57/-2=x

57/2=x

x=28.5

Step-by-step explanation:

16.86 square units

Step-by-step explanation:

I think this is the answer.

[tex]\huge\boxed{r=\dfrac{57}{5}\to r=11\dfrac{2}{5}\to r=11.4}[/tex]

Step-by-step explanation:

[tex]19=\dfrac{5}{3}r\to\dfrac{5}{3}r=19\qquad|\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup\cdot\dfrac{5}{3\!\!\!\!\diagup}r=19\cdot3\\\\5r=57\qquad|\text{divide both sides by 5}\\\\\dfrac{5r}{5}=\dfrac{57}{5}\\\\r=\dfrac{57}{5}\to r=11\dfrac{2}{5}\to r=11.4[/tex]

Average speed, v = 1.66 km/h

Explanation:

It is given that, Ian walks 2 km to his best friend’s house, then walks 0.5 km to the library. He then makes a 2.5 km walk home.

Total time taken in the entire walk, t = 3 hours

We need to find the average speed of the Ian during his journey.

Total distance covered is,

Average velocity,

So, the average speed during the entire journey is 1.66 km/h. Hence, this is the required solution.
