Answer:
Step-by-step explanation:
To find the HCF of 144 and 180
By using product of prime method
Firstly express 144 as a product of it prime and express 180 as a product of it prime
140=2×2×2×2×3×3
180=2×2×3×3×5
Common factor =2×2×3×3
36
in term of m
m=36
13m-3
To find m
Substitute for m when m=36
13(36)-3=
465
Answer:
D 28 inches
Step-by-step explanation:
mean : average
So to find the mean add all of the numbers in April and divide by the total number of different heights there were:
(12+15+23+11+12+19+20+12+11+14+12+13) ÷ 12 = 14.5
Do the same for the heights in June:
(42+45+44+39+45+45+40+43+41+40+45+41) ÷ 12 = 42.5
Then subtract the means to find the difference:
14.5 - 42.5 = -28
Since its a real world problem the answer can’t be negative
Therefore the answer is D 28 inches
