Answer:

3 1/10

Step-by-step explanation:

You can make 3 1/2 an improper fraction and then subtract it from 2/5

We do across so 7 x 5 is 35. 2 x 2 is 4. 2 x 5 is 10. 35 - 4 is 31. 31/10 simplified is 3 1/10.

So your answer is: 3 1/10

Answer:

  71°

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary.

  ∠H = 180° -109° = 71°

_____

<em>Additional comment</em>

The above rule comes from the more general rule that the measure of an inscribed angle is half the measure of the arc it intercepts. Here, inscribed angle J intercepts arc GHI, so that arc has measure 2×109°. Then the measure of short arc GI is 360° -2×109°, and inscribed angle H is half that:

  ∠H = (1/2)(360° -2×109°)

  ∠H = 180° -109° = 71°

The area of a circle is 50.24 square miles. What is the circle's diameter? Use 3.14 for Pi.
ratelena [41]

Answer:

diameter = 8 miles

Step-by-step explanation:

Area of a circle = πr²

πr² = 50.24

3.14*r² = 50.24

r²= \frac{50.24}{3.14}\\\\

r² = 16

r² = 4²

r=√4²

r = 4 miles

diameter = 2 *radius = 2*4 = 8 miles
