Answer:
12 cans of Coke for $23
Step-by-step explanation:
6 cans of coke for $ 12 means for each can I will pay $2 ( $12/6)
12 cans of Coke for $23 means for each can I will pay $1.92 ($23/12)
I would rather buy 12 cans of coke for $23 because 6×2=12 and 12×2=24 as you can see with 6 can its twice as much to buy it but with 12 cans it's a little less than twice probably like 1.5 or smth but it's one dollar less than what it was supposed to be
6.72
7.26
67.02
72.06
Answer:
76.2, 72.06, 67.02, 7.26, 6.72
Step-by-step explanation:
the largest number is 76.2, while the smallest is 6.72. The rest is clear afterwards.
PART A: At a certain number of visits, both plans will cost the same. At that number, how much will both plans cost, in dollars?
PART B: Which plan is more expensive at the 10th visit?
Write the number of the plan in the box.
After 15 number of visits, both plans cost $55 and at the 10th visit, plan 2 is more expensive than plan 1.
Arithmetic sequence is a sequence of numbers where the numbers are arranged ion a definite order such that the difference of two consecutive numbers is a constant. This constant of difference is called common difference which is commonly denoted by the letter 'd'.
Part A :
From the table, we can clearly express both plans as Arithmetic sequence.
Plan 1 : First term, a = 27 and common difference, d = 2
Plan 2 : First term, a = 41 and common difference, d = 1
Let n be the number of visits that both plans costs the same.
27 + 2(n - 1) = 41 + (n - 1)
27 + 2n - 2 = 41 + n - 1
2n + 25 = n + 40
n = 15
Cost = 41 + (15 - 1) = $55
Part B :
We have to find the 10th term.
For plan 1 :
Cost at 10th visit = 27 + 2(10 - 1) = $45
For plan 2 :
Cost at 10th visit = 41 + (10 - 1) = $50
The plan 2 is more expensive at the 10th visit.
Hence at the 10th visit, plan 2 is more expensive.

Step-by-step explanation:
From the looks of it, Plan A is 25 + 2x and plan B is 40 + x.
Part A:
25 + 2x = 40 + x
x = 15
plug in any: 40 + 15 = $55
Part B:
Plan A = $45
Plan B = $50
Plan B is $5 more expensive.
b. 5.454 x 10^6 square kilometers
c. 1.44 x 10^7 square kilometers
d. 5.454 x 10^7 square kilometers
Answer:
d. 5.454 x 10^7 square kilometers
Step-by-step explanation:
Adding 4.46×10^7 to 0.994×10^7 we get 5.454×10^7.
___
Before you can add numbers in scientific notation, they must both have the same multiplier. Here, we can see that the area of Asia will be written with an exponent of 7, so we choose to write both numbers that way.
44,600,000 = 4.4×10,000,000 = 4.4×10^7
9.94×10^6 = (0.994×10)×10^6 = 0.994×10^7
The sum is (4.400 +0.994)×10^7 = 5.454×10^7.
Combined area is 5.454 × 10^7 km²
Step-by-step explanation:
Area of Asia = 44,600,000 km²
Area of Europe = 9,943,106 km²
⇒ Combined Area = 44,600,000 + 9,943,106
= 54,543,106 km²
54,543,106 = 5.454 × 10^7 km² (Dividing and multiplying by 10^7)
