Answer:
You save 86 cents per pound.
Step-by-step explanation:
According to the given problem, grocery store B charges chicken 5 pounds of chicken for $38.20. Consider finding the unit price:
To find the unit price of any item, do the following calculation:
Total Price / Total amount = $$$ per amount.
The unit price of store b is . In other words, every pound of chicken costs $7.64 at store b.
For store a, we are provided with a table. Given how the question is being asked, we should <u>expect a higher unit price</u>. We can take any charge to find the unit price since the price should be consistent no matter how many pounds you buy. I will calculate the first row:
In other words, every pound of chicken costs $8.50 at store a. <u>This price is higher</u>. You can verify this is the correct unit price by multiplying the unit price with any amount of pounds provided at the table. You should get the total cost.
So, now that we have both unit prices, we can calculate the difference to find out how much we save per pound when choosing store b:
8.50-7.64=0.86.
Answer:
Step-by-step explanation:
To find out the m(slope) of the equation use the formula:
.
Substitute the values:
Combine the values:
Find the value of the fraction:
M is -3.
The equation so far is
To find the y intercept, substitute one pair of coordinates into the equation and solve for b:
.
We see that b =-17 so the full equation would be:
.
Answer:

.
Step-by-step explanation:
The question states that is proportional to
. In other words, there is a constant
(
) such that
for all

Step-by-step explanation:
a). The decimal numbers is equal to the sum of binary numbers times their powers of
That is,
=
= 58490
b).
The left most bit of the number represents the sign of the number. If bit = 1, the number is negative else if the bit is 0, the number is positive.
All the remaining bits (i.e all the bits except the leftmost bit) represent the magnitude of the number.
Now, X = 1110 0100 0111 1010
left most bit = 1 => number is negative
remaining bits Y = 110 0100 0111 1010
converting Y to decimal => Y = 25722
c).
Check the leftmost bit(lmb) of the number
if leftmost bit is 0 => convert do the binary to decimal conversion
if leftmost bit is 1, follow the following steps
1. Flip the bits (convert the 0's into 1's and the vice versa)
2. convert the new number from binary to decimal.
3. Add a negative sign / multiply by -1
Now, X = 1110 0100 0111 1010
left most bit = 1;
flipping the bits => Y = 0001 1011 1000 0101
converting Y into decimal => Y = 7045
multiplying Y with -1 => Y = -7045
Therefore, one's complement of X to decimal is -7045
Thus, X = -25722 in decimal.
d).
Check the leftmost bit(lmb) of the number
if leftmost bit is 0 => convert do the binary to decimal conversion
if leftmost bit is 1, follow the following steps
1. Flip the bits (convert the 0's into 1's and the vice versa)
2. convert the new number from binary to decimal.
3. Add 1 to the converted number
4. Add a negative sign / multiply by -1
Now, X = 1110 0100 0111 1010
left most bit = 1;
flipping the bits => Y = 0001 1011 1000 0101
converting Y into decimal => Y = 7045
Adding 1 to Y => Y = 7046
multiplying Y with -1 => Y = -7046
Thus, two's complement of X to decimal is -7046
