Answer:
13 cents, 17 cents, Brand A
Step-by-step explanation:
The unit price is the price of a single pencil. You can find that by dividing the total price by the number of pencils.
Brand A= $2.36/18= $0.13
Band B= $4.09/24= $0.17
0.13 < 0.17
Brand A is cheaper because the price per pencil is less.
2/5/9 solved will be 0.4 repeating as a decimal, & 4/9 as a fraction
With every imaginary term, there are 2 complex conjugates with opposing signs. So if I had the term a+bi, the complex conjugate would be a-bi. So given your example of -1+4i, the complex conjugate would just be the opposite sign, now negative, to get -1-4i.
Answer:
Find below:
Step-by-step explanation:
To solve this, we either find the total cos5 of buying 40 bouquets at $2.50 or find the cost of one bouquet at $120.
Cost of one in pack of 40 at $120.
120 divided by 40 = $ 3
Now, we can see that $3>$2.50
This means that Kendra is wrong to buy the bouquet pack of 40 for $120
Hope this helps.
Good Luck
