does somebody knows how to do this one?
vlada-n [284]

Answer:

Step-by-step explanation:

To find the area subtract the area of the semicircle from the area of the rectangle.

Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.

The area of rectangle is:

⇒ A = lw

⇒ A = (14)(8)

⇒ A = 112cm^{2}

The area of the semicircle;

⇒ A = \frac{1}{2}\pi r^{2}

⇒ A = \frac{1}{2}\pi (7)^{2}

*Note here that the radius is half the diameter, so it is 7cm, not 14cm

⇒ A = 76.97cm^{2}

Finally subtract the two areas;

⇒ A = 112 - 76.97

⇒ A = 35.03cm^{2}

Ed is on a road trip he has already traveled 201 miles and is driving at a rate of 61 mph the equation could be used to find how
Bas_tet [7]

Answer:

Ed has traveled for 3 hours and 17 minutes, and has 2 hours and 28 minutes left to travel.

Step-by-step explanation:

Given that Ed is on a road trip and he has already traveled 201 miles and is driving at a rate of 61 mph, the equation could be used to find how many hours he has traveled and how many and has left in his road trip traveling 697 total miles is the next:

201/61 = 3.29

100 = 60

29 = X

29 x 60/100 = X

29 x 0.6 = X

17.4 = X

So, Ed has traveled for 3 hours and 17 minutes.

697 - 201 = 496

496/201 = 2.46

100 = 60

46 = 0

46 x 0.6 = X

27.6 = X

Thus, he has 2 hours and 28 minutes to travel.
