One train was going 80 miles the other was going 50.

39 mph, because 390 divided by 30 equals 13, and since they both pass 3 hours later you do 13 multiplied by 3 which is 39

Any x in this set will be real numbers that are both less than -3 and greater than 5. But that's not possible, so this set is empty.

Find the area of the composite figure in terms of the figure (use 3.14 for pi)​
svp [43]

Answer:

105.12 ft²

Step-by-step explanation:

Let's first find the area of the rectangle.

10\cdot8=80 ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is \pi r^2. The radius is 4, as the diameter is 8.

3.14\cdot4^2

3.14\cdot16

50.24\div2=25.12

Add 80 and 25.12:

80+25.12=105.12

Hope this helped!

Can someone please do this for me?

Answer:

64°

Step-by-step explanation:

<em>So supplement angles are equal to 180, so first our two angles added together will be 180:</em>

x + x = 180

<em>Now one of these angles is 6 greater than half:</em>

x + (x/2 + 6) = 180

<em>Then we will solve for x:</em>

x + (x/2 + 6) = 180

x + x/2 + 6 = 180

x + x/2 = 174

\frac{3}{2}x = 174

x = 116

<em>Plug it back in:</em>

x + (x/2 + 6) = 180

         /\

     x/2 + 6

   (116)/2 + 6

        64

<em>To check:</em>

116 + 64 = 180 ✓
