I need 3 equivalent ratios for 21:56, 48:36, 6:54 and 22:55

This seems like a high school question. I will use trigonometry.

The three points (P, O, and the point on the ground directly below P [call it G]) form a right triangle. The 42-degree angle is opposite PG, the altitude of the plane. Since we are told to find x, which is PO, we can use the definition of the sine function, which is opposite divided by hypotenuse.

Solving for x,

This makes sense because the hypotenuse must be longer than either of the legs.

Answer:

first one or a  perimeter is 24 and area is 20 second or b perimeter is 18 and area is 20

third or c is 24 and area is 36 fourth or d  is perimeter is 26 and area is 36

Step-by-step explanation:

Answer: the answer is four

Final answer:

To find the number of seashells Carme has now, multiply the initial number of seashells by the number of boxes and subtract the number she gave away.

Explanation:

To find the number of seashells Carmen has now, follow these steps:

1. Multiply the number of boxes she initially had (10) by the number of seashells in each box (6). This gives you the total number of seashells she started with (60).
2. Subtract the number of seashells she gave away (5) from the total number she started with. This will give you the number of seashells she has now.

Using the steps above, we can calculate:

1. Initial number of seashells = 10 boxes x 6 seashells per box = 60 seashells
2. Number of seashells she has now = 60 seashells - 5 seashells she gave away = 55 seashells

Therefore, Carmen now has 55 seashells.
