Answer:
1) Area = 12cm²
2) x = 5cm
Surface area : 69cm²
Step-by-step explanation:
Opposites sides in a rectangle would equal the same.
so Top/bottom = 20+20=40
Front/back = 15+15=30
40+30=70cm²
94-70=24cm² for left and right side 24÷2=12cm²
2) Those lines represents what side it is equal too which also means the same.
3cm, you know that base x height = surface area so surface area ÷ height = base
15/3=5cm
x=5cm
Formula : Base x Height = One surface area
Front/Back= 15+15=30
Top/bottom = 5x3 = 15+15=30
side/side = 3x3=9
30+30+9=69cm²
Answer: B
Step-by-step explanation:
none of the other's worked except for B
A : 2(1), 2(1) = (2,2) which is A'
B : 2(2), 2(4) = (4, 8) which is B'
C : 2(4), 2(1) = (8, 2) which is C'
Answer:
see explanation
Step-by-step explanation:
The n th term (explicit rule) of a geometric sequence is
= a₁ 
where a₁ is the first term and r is the common ratio
here a₁ = 60 and r = 
= 
, hence
= 60 
The probability of randomly selecting a tree or a flower is 8/15.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of randomly selecting a tree or a flower = (number of trees / total number of flash cards) + (number of flowers / total number of flash cards)
8/30 + 8/30 = 16/30 = 8/15
