Answer:
es ocho es facil cuenta si esque estoy bien
Step-by-step explanation:
50*2= 100
So 50 is one half of One hundred and if we use 100 divided by 2 to get 50 then we need to do 80 / 2 which will give us 40.

Answer:

Step-by-step explanation:
In this problem, one is given a circle with two secants (that is a line that intersects a circle at two points). One is given certain measurements, the problem asks one to find the unknown measurements.
The product of the lengths theorem gives a ratio between the lengths in the secants. Call the part of the secant that is inside the circle (inside), and the part of the secant between the exterior of the circle and the point of intersection of the secants (outside). The sum of (inside) and (outside) make up the entire secant, call this measurement (total). Remember, there are two secants, (
) and (
) in this situation. With these naming in mind, one can state the product of the length ratio as the following:

Alternatively, one can state it like the following ratio:

Apply this ratio to the given problem, substitute the lengths of the sides of the secants in and solve for the unknown.


Cross products, multiply the numerator and denominators of opposite sides of the fraction together,


Simplify,


Inverse operations,


Substitute this value into the equation given for the measure of (EF),

Answer:
The least possible number of coins the Pirate has = 81
Step-by-step explanation:
Given:
Pirate Jack has equal number of gold and silver coins.
When the pirate splits the coins into 7 equal piles he has 4 coins left.
When the pirate splits the coins into 11 equal piles he has 4 coins left.
Every pile has at least 1 coin.
To find the least possible number of coins Pirate Jack has.
Solution:
In order to find the least possible number of coins pirate Jack has, we must find the least common multiple of the number of piles the coins are split into.
So, the least common multiple of 7 and 11 can be found by listing the multiples.


So, we find the least common multiple of 7 and 11 is 77.
Number of coins left = 4
Total number of coins the pirate must have = 
We can check the answer by dividing 81 by 7 and 11. I both cases we get remainder = 4.
So, the least possible number of coins the pirate has = 81
