13 red, 5 blue, 7 green...for a total of 25
percentage of green ones is : 7/25 = 0.28 = 28% <==
So in order to find line AC you must find line AD and DC then plus them together.
to find AD use Pythagoras theorem
a^2 = c^2 - b^2
AD^2 = 7.5^2 - 6.5^2
AD^2 = 56.25 - 42.25
AD^2 = 14
square root both sides to get rid of the ^2
AD ≈ 3.7 or 3.74
Do the same for DC
DC^2 = 10^2 - 6.5^2
DC^2 = 100 - 42.25
DC^2 = 57.75
DC ≈ 7.6
now plus AD and DC which should give u 11.3
Answer:
74 cm squared
Step-by-step explanation:
because each triangle will be 7, and each rectangle will be 20. (7*2)+(3*20)=74
To find the median, first arrange from least to greatest.
11 , 13 , 17 , 19 , 19 ,23
The median is now between 17 and 19 which is 18.
Ur answer is C)
Answer:
b. 256
Step-by-step explanation:
Data:
W= 8
L= 8
H= 8
soln:
firstly the formula of lateral area is
LSA = (2W+2L) H
therefore:
LSA = (2×8+2×8) 8
LSA = (16+16) 8
LSA = (32) 8
LSA = 256
