hope this helps <3
Step-by-step explanation:
- write down the binary number; 110011
- multiply each digit of the binary number by the corresponding power of two: (1×2)5 + (1×2)4 +(0×2)2 +(0×2)2 + (1×2)1 +(1×2)0
- Solve the power: 1×32+1×16+0×8+0×4+1×2+1×1= 32+16+0+0+2+1
- Add up the numbers written above: 32+16+0+0+2+1= 51
So, 51 is the decimal equivalent of the binary number 110011.
Call the number of hours babysitting
and the number of hours walking dogs
.
We know that she earns $6/hr for babysitting or
, and $5/hr walking dogs or
. We also know the total money is $43 and the total time is 8hours. Therefore:
To solve: First rearrange equation 1 to solve for either
or
(doesn't matter which, I'll use
):
Now substitute into equation 2:
and solve for
Now backsubstitute to solve for
:

Answer:
50, 60, 50, and 60
Step-by-step explanation:
xy = 3000
2x + 2y = 220
Rewrite the second equation
y = -x + 110
Substitute this into the first equation.
x(-x + 110) = 3000
-x^2 + 110x - 3000
Divide by -1
x^2 - 110x + 3000
(x - 60) (x - 50)
x = 60, 50
When x = 60, y = 50 and vice versa, so the sides are 50, 60, 50, and 60.
