Answer:
A. 10,000
B. 1,000,000
C. 10,000,000,000
D. 1,000,000,000,000
Step-by-step explanation:
10,000/ 10∧4 = 1
1,000,000/ 10∧6 = 1
10,000,000,000/ 10∧10 = 1
1,000,000,000,000/ 10∧12 = 1
Hope this helps! Good luck!
Answer:
The numbers are 3, 12 and 5.
Step-by-step explanation:
Let the numbers =x, y and z.
The sum of three numbers is 20 implies x+y+z=20----------------i
The second number is 4 times the first implies y=4x--------------ii
The sum of the first and the third is 8 means x+z=8---------------iii
from (i), z=20-x-y---------iv
Put (iv) in (iii),
x+20-x-y=8
20-y=8
y=20-8=12
y=12
Put y=12 in (ii)
4x=y
x=y/4 = 12/4 = 3
x=3
Put x=3 and y=12 in (iv)
z=20-3-12=5
z=5
Therefore, the numbers are 3, 12 and 5.
Answer:
28:26
Explanation:
Because a ratio compares things. Since there are 26 students on the floor, and 28 students on the bleachers, you would type 28:26.

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
ANSWER: 10
