Answer is 1/16 because if you look at 4, we can toss it 16 times by arranging in a different way .

2. The beam of a lighthouse can be seen for up to 20 miles. You are on a ship that is 10 miles east and 16 miles north of the li

Answer:

<em>The person on the ship can see the lighthouse </em>

Step-by-step explanation:

<u>The Circle Function </u>

A circle centered in the point (h,k) with a radius r can be written as the equation

$(x-h)^2+(y-k)^2=r^2$

Any point (x,y) can be known if it's inside of the circle if

$(x-h)^2+(y-k)^2\leq r^2$

The question is about a beam of a lighthouse than can be seen for up to 20 miles. If we assume the lighthouse is emitting the beam as the shape of a circle centered in (0,0), then its radius is 20 miles. Thus any person riding a ship inside the circle can see the lighthouse. This means that

$x^2+y^2\leq 20^2$

$x^2+y^2\leq 400$

The ship's coordinates respect to the lighthouse are (10,16). We should test the point to verify if the above inequality stands

$10^2+16^2\leq 400$

$356 \leq 400$

The inequality is true, so the person on the ship can see the lighthouse

PLEASE HELP!!!! Emily is making 2 gallons of punch with 4 parts grape juice to 3 parts pineapple juice to 1 part sparkling cider

True [87]

1 gallon = 16 cups. She is making 2 gallons so needs 32 total cups.

The ratio is 4:3:1

Add the ratios: 4+ 3 + 1 = 8

Divide total cups by total ratio:

32/8 =4

Now multiply that by each portion of the ratio:

Grape juice = 4 x 4 = 16 cups

Pineapple juice = 3x4 = 12 cups

Cider = 1x 4 = 4 cups

She needs 12 cups of pineapple juice.

What is the answer to this problem?

Amanda [17]

Answer:

B.) Transitive Property of Congruency; If parallel lines have a transversal, then alternative interior angles are congruent.

Step-by-step explanation:

Alternate interior angles are the two angles that are inbetween the parallel lines but are on opposite sides of the transversal. Angles 4 and 5 are alternate interior, and therefore, they are congruent.
