What must the measure of angle LMN be? m∠LMN = °
luda_lava [24]
Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.
25x  = 22x + 9
Subtract 22x from both sides.
3x = 9
and you're left with this.
Next, divide 3 from both sides.
x = 3
re-insert 3 into one of the equations.
25(3) = 75
add up both angles
75 + 75 = 150
all angles (for quadrilaterals)added up equals 360.
150 + 2x = 360
solve for x. Subtract 150 from both sides.
2x = 210
and divide 2 from both sides
x = 105
AngleLMN= 105

Answer:

After 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.

Step-by-step explanation:

Since after a while, Jada picks up a coin that seems different than the others, and she notices that the next day, only half of the coin is left, while on the second day, only 1/4 of the coin is left and, on the third day, 1/8 of the coin remains, to determine what fraction of the coin remains after 6 days, what fraction of the coin remains after 28 days and determine if the coin will disappear completely, the following calculation must be performed:

1/2 ^ 6 = X

0.015625 = X

1/64 = X

1/2 ^ 28 = X

0.0000000037252902984619140625 = X

1/268435456 = X

Thus, after 6 days 1/64 of the coin will remain, while after 28 days 1/268435456 will remain. Now, it will never completely disappear, since it can always be reduced to a larger number.
