well, what we do is, simply get the area of the containing rectangle, is an 8x10, and then get the area of the circle, with a radius of half of 4.3 or r = 2.15, and then if we subtract the area of the circle from the rectangle's, what's leftover is the shaded part.

\stackrel{\textit{\large Areas}}{\stackrel{rectangle's}{(8\cdot 10)}~~-~~\stackrel{circle's}{[\pi (2.15)^2]}}\implies 80-4.6225\pi ~~\approx~~65.5

You make punch for a party. The ratio og ginger ale to fruit juice is 8 cups to 3 cups. You decide to add 4 more cups of ginger
Dvinal [7]
To get the answer we can use proportion
8 ginger ----------------- 3 fruit
12 ginger ----------------x
Crossmultiply now
8x=12*3                /:8
x=\frac{12*3}{8}
x=<u />\frac{36}{8}  \\ x=4.5
To not change ratio we have to have 4.5 cups of fruilt juice. We initialy had 3, so we have to add 1.5 cup of fruit juice.

4. A ship travels due east at 10 mph for 5 hrs. It then turns on to a bearing 36° and continues for another 2 hrs. How far is it
Mama L [17]

Answer:

35.8miles

Step-by-step explanation:

The scalene triangle is a type of triangle with sides of three different lengths and angles of three different measurements. In every scalene triangle, the shortest side is opposite the smallest angle and the longest side is opposite the largest angle

10 mph x 5hrs = 50 miles could be the longest side

+36 degree = 1/10 of full rotation, is likely to be opposite the smallest angle =20 degree opposite 20miles but we deduct 1/10 rotation to show 1/10 of 20 is 0.8 x 0.8 = 0.64 and is the inverse 1/10 of 36 degree.

We use trigonometry function the sine of the angle = the length of the opposite side. the length of the hypotenuse = 20/50 sin (30)= 1.25 and this estimates the larger angle 125

We find 35.8m through division.

We can check that 35.8 + 20 + 50 = 105.804 perimeter

We cna also multiply the radical adding -1 infront of the angle 36 and multiplifyling the scale of 5 and 2 = 2.5

2.17874 x -136 x 2.5 = -741

1800-741 = 1058/10 perimeter.

and each has angle 36, 124.8,  19.2
