Answer:
$81.92
Step-by-step explanation:
Week 1:
250 * 20% = 50
250 - 50 = 200
Week 2:
200 * 20% = 40
200 - 40 = 160
Week 3:
160 * 20% = 32
160 - 32 = 128
Week 4:
128 * 20% = 25.6
128 - 25.6 = 102.4
Week 5:
102.4 * 20% = 20.48
102.4 - 20.48 = 81.92
42 x 1.07 = 44.94
44.94 - 2.94 = 42
58 x 1.07 = 62.06$
Answer:
After solving we get
Step-by-step explanation:
We need to solve the equation:
Solving:
Multiply 4x with terms inside the bracket
We need to solve above equation to find value of x
Using quadratic formula for finding value of x:
We have a=180, b=-28 and c=-57
Values of x are
So, After solving we get
Answer:
150161 in base 8.
= 347^2 base 8.
Step-by-step explanation:
11100111^2
the last 4 digits of this binary number = 7 in base 10.
The number 11100000 in base 10 = 1*2^5 + 1*2^6 + 1*2^7
= 224 base 10
So 11100111 = 231 base 10.
231^2 = 53361.
Now convert this to base 8:
We divide by 8
8 | 53361
8 | 6670 remainder 1
8 | 833 rem 6
8 | 104 rem 1
8 | 13 rem 0
8 | 1 rem 5
| 0 rem 1
So the answer is 150161
