First, we need to find the original ratio of 7th to 6th
6th = 12
7th = 21
21:12
Then find any common factors
21: 1,3,7,21
12: 1,2,3,4,6,12
divide 21 and 12 both by 3
21/ 3 = 7
12 / 3 = 4
7:4 is your ratio
For every 7 students in 7th grade, there are 4 students in 6th grade.
Answer:
Step-by-step explanation:

42240/60
because it's yards to min not yards to hours any more
= 704 yds

Answer:
answer of 13) Lenght of one edge of this cube = 3cm
answer of 14) The area of BCE = 25 cm^2
Step-by-step explanation:
Any cube has six identical sides.
Let one side have an area of A.
Let the lenght of one cubic side be L.
L * L = A
So this results in L = SQRT (A)
All six A combined add up to 54 cm^2.
Then 6 * A = 54
A = 54/6 = 9 cm^2
L = SQRT (9)
Lenght of one edge of this cube = 3cm
To find the area of BCE you can simply subtract the area of CDE from the biggest triangle BDE.
2 * BDE = {5+4) * 10
so BDE = 45
2 * CDE = 4 * 10
so CDE = 20
BCE = BDE - CDE
BCE = 45 - 20
The area of BCE = 25 cm^2
