Remark
I'm going to assume that it is just the 0.41 that is doing the repeating. If it is not leave me a note.
Solution
The trick is to call x = 3.4141414141 ....
then multiply by 100
100 x = 341.4141414141 ............ Now write the original decimal underneath.
<u>. . . x = 3.414141414141 ......</u>...... Subtract
99 x = 338 That's all that's left. The decimal part cancels out.
x = 338 / 99 Fractional answer.
x = 3 39/99
x = 3 13/33 If this isn't one of your answers, leave me a note.
Answer:
X+12
Step-by-step explanation:
"Increased by" means addition.
Answer:
-36
Step-by-step explanation:
To get 4% of 800 you times 800 by 4 and divide it by 100. Once you have that amount you add it to 800 to find the amount you will have in your bank the first year.
To get the next year's amount you then get 4% of 832(because after the first year you have more than $800) and then add the 4% to 832, that is the answer for the second year.
To find the third year's amount you get 4% of the new amount (last year's total) and add it to last year's total, that is your total for the third year.
So the first year will be:
(800x4÷100)+800
=32+800
=832
The second year will be:
832+(832x4÷100)
=832+33.28
=865.28
The third year will be:
(865.28×4÷100)+865.28
=34.61(rounded off)+865.28
=899.89
Answer:
- w = 8
- x = 8√2
- y = 8√2
- z = 16
Step-by-step explanation:
A 45-45-90 right triangle is isosceles. That means both legs are the same length, and its hypotenuse is √2 times the leg length. You can figure these facts using trigonometry or the Pythagorean theorem, or you can rely on your memory of them.
w = 8 . . . . . . . . . . . same as the leg length shown
x = y = 8√2 . . . . . hypotenuse of smaller triangle; both legs are the same
z = (8√2)√2 = 16 . . . . hypotenuse of larger triangle
