100 x .4 = 40
40 x 12 = 480
The bank account would have $480 over 12 years. Hope this helps and please mark brainliest
I'm assuming, from what you've given me that the question is asking to do this.
15n=647
647 divided by 15 equals 43.13...repeated
Let me know if this is what you are looking for.
The legs of the triangle are 6.91 feet, 7.9 feet, and 10.5 feet.
<h3>What is a Pythagoras theorem?</h3>
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The ratio of the one leg of the right triangle to the other leg of the right triangle must be 8:7.
Let x be one leg and y be another leg. Then we have
x/y = 8/7
y = 7x/8
Then the greatest length of one leg of the right triangle given the other leg of the right triangle is 10.5 feet will be
10.5² = x² + (7x/8)²
110.25 = x² + 49x²/64
110.25 = 113x²/64
x² = 62.44
x = 7.902
x ≅ 7.9 feet
Then the other leg will be
y = 7.9 x 7 / 8
y = 6.91

Ok here we go, I will go step-by-step:
So first we have to figure out what y is. we see that the angles outside y are 52 and 59, so we add those together and get 111. now we know whatever y is, it has to equal 180 when added to 111 because it is a straight line. Therefore, angle y is 69 degrees. Now, we also know the angles inside a triangle have to equal 180 when added together. we know two of them. They are 63 and 69. Add those together and we get 132. That means x has to equal 48, to make the inside angles equal 180. The answer is x=48
