Lindsey is fishing from a small boat her fishing hook is 12 m below her, and a fish is swimming at the same depth as the hook, 16 m away. how far is lindsey from the fish

Lindsey is 20 m away from the fish.

Step-by-step explanation:

To solve this, I first drew it out. Lindsey is in a boat and her hook is a vertical line below her. Label this line 12m since the hook is 12 m below her.

Next, go from the hook and draw a horizontal line to the fish. Label this line 16m since that's how far the fish is from the hook.

Now, create a dashed  diagonal line from Lindsey to the fish, this is the distance we want to find.

Notice that we've created a triangle and that the dashed line is the hypotenuse. A hypotenuse is the side of a triangle that is opposite to a 90 degree angle in a right triangle. To find the length of a hypotenuse we can use the Pythagorean theorem.

a and b are the lengths of the two sides of the triangle that are not the hypotenuse, so:

the length of the dashed line between Lindsey and the fish is 20m, so Lindsey is 20m away from the fish.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
