Answer:
The price of the computer is $1,152
Step-by-step explanation:
Let the price of the computer be $x
The first boy boy had 7/8 of this amount, the amount he has is thus 7/8 × $x = 7x/8
The second boy had 5/6 of what the first boy had. The amount of money he has is thus 5/6 × 7x/8 = 35x/48
Now, the addition of what they have is $696 more than what they need to pay. This amount is x+ 696
Mathematically, this can be represented as;
7x/8 + 35x/48 = x + 696
(42x + 35x)/48 = (x + 696)
77x/48 = (x + 696)
77x = 48(x + 696)
77x = 48x + 33408
77x - 48x = 33408
29x = 33, 408
x = 33,408/29
x = $1,152
-3 × 1/3 equals -1 because -1 is one third of -3.
Answer:
454.54 days
Step-by-step explanation:
100,000/220= 454.54 (divide)
This is a 45/45/90 triangle, meaning that one angle is 90 degrees and the two legs both are 45 degrees. So, we can come to the conclusion that both of the legs are the same, which is the 3 radical two.
The hypotenuse in this type of triangle is twice as big, so we would multiply 3 radical 2 by radical 2. That gives us 6 for an answer.
So, the hypotenuse equals 6.
If you need help multiplying radicals let me know and I can explain :)
