Answer:
The Possible dimension of the ring could be;
20 ft × 60 ft
25 ft × 48 ft
30 ft × 40 ft
60 ft × 20 ft
48 ft × 25 ft
40 ft × 30 ft
Step-by-step explanation:
Given:
Number of skaters = 30
Area for each skater = 40 sq ft
We need to find the dimension of rectangular ring the are going to build.
Now we know that they building the skating ring such that they all can use at same time.
Hence if the all use at same time then we will find the total area first.
Total area can be calculated by multiplying Number of skaters with area required for each skaters.
Framing the equation we get;
Total area = 
Hence The total area of the rectangular ring would be 1200 sq. ft.
Now we know that Total area is equal to product of length and width.
1200 can be written as = 20 × 60, 25 × 48, 30 × 40,60 × 20,48 × 25,40 × 30
Hence the Possible dimension of the ring could be;
20 ft × 60 ft
25 ft × 48 ft
30 ft × 40 ft
60 ft × 20 ft
48 ft × 25 ft
40 ft × 30 ft
9 packets.
36 divided by 3 = 12
49 divided by 5 = 9.8
76 divided by 7 = 10.8
Maximum packets that can be obtained is 9 packets because only 9 packets with 5 green beads each can be packaged.
Answer:
A) $2.42, $2.33, $2.58
B) The best deal is 24 cupcakes for $56
Step-by-step explanation:
<span>k= Keisha
k + 6=
John</span>
<span>
k + k + 6
= 4k</span>
<span>
2k + 6 ( - 2k)
= 4k ( - 2k)</span>
<span>
6 = 2k</span>
<span>
3 =
k
(Keisha= 3 years old)</span>
<span>
k + 6 = 9
(John = 9 years old)
</span>
3 + 3 + 6 = 4 (3)
<span>
12 = 12
</span><span>So
we made the pawn represent Keisha’s age.
Then we knew that John is 6 years older than Keisha so we represented
his age with a pawn plus 6. This went on 1 side of the equation because it said
that together they equal 4 times Keisha’s age. So on the other side of the
equation we put 4 pawns because we are using each pawn as Keisha’s age. Then we subtracted the pawns from each side
to keep the equation balanced. So we had
that 2 pawns equal 6, which means that each pawn equals 3 so Keisha is 3 years
old. Since John is 6 years older than
Keisha, he must be 9 years old. We
checked our work and substituted 6 in for each pawn and found that 12 equals
12, so our equation is balanced.

Hope this helps :)
