Answer:
113 
Step-by-step explanation:
top rectangle = l x w = 6 x 13 = 78
lower rectangle width = 13-8=5. so a = l x w. 7 5 = 35
78+35= 113
Answer:
x = 20
Step-by-step explanation:
90 = 60 + (x + 10)
90 - 60 = x + 10
30 = x + 10
30 - 10 = x
20 = x
A = bh
b = 4h
A = 324
324 = 4h * h
324 = 4h^2
324/4 = h^2
81 = h^2
sqrt 81 = h
9 = h
b = 4h
b = 4(9)
b = 36
so the height (h) = 9 cm and the base (b) = 36 cm
<u>Answer:
</u>
The probability of rolling a number greater than 4 or less than 3 is 
<u>Solution:
</u>
In the given question there are two events as follows:
(a) Rolling a number greater than 4 i.e. A = {5,6}
(b) Rolling a number less than 3 i.e. B = {1,2}
Since a die has 6 numbers,
P(A) =
where P(A) is the probability of occurrence of event A and P(B) = 
Since, Event A and Event B has nothing in common therefore they are mutually exclusive events.
P(A∪B) = P(A) + P(B)



Therefore the probability of getting a number greater than 4 or less than 3 is
