I would say 244.8 minutes but I've been wrong before.
Answer:
Ellen will pay $16.22 for the book.
Step-by-step explanation:
Part 1:
We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.
18 x 0.15 = $2.70
This lets us know that there is a $2.70 discount.
Now, let's subtract the discount from the regular price.
18 - 2.70 = $15.30
So, now we know the discounted price is $15.30
Part 2:
We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.
15.30 x 1.06 = $16.22 when rounded to the nearest cent.
Therefore, Ellen will pay the total amount of $16.22.
Answer:4/9
Step-by-step explanation:
Answer:
The correct answer is P = 24 + 8x.
Step-by-step explanation:
First, we must express the length and width of the frame.
Length = 7 + 2x
Width = 5 + 2x
The perimeter is the sum of the four sides of the frame.
P = 2 * (7 + 2x) + 2 * (5 + 2x)
P = 14 + 4x + 10 + 4x
P = 24 + 8x
In this way, we express the perimeter (P) of the frame.
Have a nice day!
Answer:
5050
Step-by-step explanation:
∑_{n=1 to 50} (4n-1)
a1=4×1-1=3
a2=4×2-1=7
a3=4×3-1=11
......................
......................
......................
a50=4×50-1=199
n=50
Sn=n/2(a1+an)
S50=50/2(3+199)=50/2×202=50×101=5050
