Answer:
22 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 3600° , then
180° (n - 2) = 3600° ( divide both sides by 180° )
n - 2 = 20 ( add 2 to both sides )
n = 22
Maybe let's just do the prime factorization.
40=2x2x2x5
answer:2^3x5
Answer:
e) 75
Step-by-step explanation:
Given the following :
Total length of cable = 60 foot
Length of each stripe = (4/5) of a feet
Number of stripes = ( total cable length / length of each stripe)
Number of stripes = ( 60 / (4/5))
Number of stripes = 60 ÷ 4/5
Number of stripes = (60 * (5/4)
= (60 * 5) / 4
= 300 / 4
= 75
Number of stripes made = 75
280=.7x
.7 because 100%-30% is 70%
Solve
280/.7=x
400=x

Answer: No
Step-by-step explanation:
The diver is at 60m below sea level, and swims upward 2m every 5 seconds.
So, since there are 24 five-second periods in 2 minutes (60secs/min), the diver would have swam up 48m after 2 minutes.
Since 60m - 48m is 12m, the diver has not yet reached the sea surface.
Hope it helps :)
