Answer:
8
Step-by-step explanation:
Let's set this up to see if we can simplify it a bit:

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top. And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom. Now that looks like this:

10 divided by 5 is 2, and 2 cubed is 8
Answer:
7.25
Step-by-step explanation:
In the question, the term at least means less than or equal to is represented by ≥
Let the cost of each gift = c
He is buying gifts for 8 friends = 8 gifts
Hence, our Inequality equation is written as:
(c + $1.50)× 8 ≥ $70
8c + 12 ≥ 70
8c ≥70 - 12
c ≥ 58/8
c≥ 7.25
Therefore, the amount Claudio needs to spend on each gift in order to receive free shipping is 7.25
The answer is 19. Hopefully this helps
Answer:
15,9,3
Step-by-step explanation:
We need to identify the perimeter of the rectangle EFGH which has points as below:
G (-3, 4)
H (2, 2)
E (1, -1)
F (-4, 1)
The distance of EF, we have it:
d² = (-4-1) ² + (1--1)² = 25 + 4 = 29
d = √29
The distance from point F to point G:
d² = (-4--3)² + (1-4)² = 1 + 9
d = √10
Hence, we can solve for the perimeter as below:
Perimeter EFGH = 2L + 2W
Perimeter EFGH = 2(√29) + 2(√10)
Perimeter EFGH = 17.09 units
The answer is the second item in the choices or the letter B which is 2√10 + 2√29 units.
