Answer:
M = 20
Step-by-step explanation:
Given that M is directly proportional to r³ then the equation relating them is
M = kr³ ← k is the constant of proportion
To find k use the condition when r = 4, M = 160, that is
160 = k × 4³ = 64k (divide both sides by 64 )
2.5 = k
M = 2.5r³ ← equation of proportion
When r = 2, then
M = 2.5 × 2³ = 2.5 × 8 = 20
Answer:
C.0
since it's literally impossible for a triangle to have a right angle only squares and other shapes. triangles are made of acute angles
I got 27.5 for the mean
mean: you add up all the #'s and divide them my their quantity( in other words by how many numbers there are)
In your case you have 8 numbers, you add them and divide them by 8!
Hope it helps ;)
Answer:
The time at which they will all meet at a place together is 350 minutes
Step-by-step explanation:
The time it takes Faiza to cycle the park = 60 seconds
The time it takes Krish to cycle the park = 14 seconds
The time it takes Joe to cycle the park = 25 seconds
Therefore, the time they will all meet at a place together is given by their Lowest Common Multiple as follows;
LCM = 60 × 14 × 25 = 21,000 seconds
Therefore, the time at which they will all meet at a place together in minutes = 21000 seconds/(60)×minute/second = 350 minutes
