Step-by-step explanation:
SA=lw+lh+hw
6*10=60
10*5=50
5*6=30
60+50+30=140
Both are similar, so Yes.
-All the sides of the squares are equal
-The triangles are also the same, just one is smaller. The one on the right is 2/3 of the one on the left.

Answer:
25%
Step-by-step explanation:
First we calculate the probability of rolling a number greater than 3, that is, it can be 4, 5 or 6.
The probability of each number is 1/6, so:
P1 = (1/6) + (1/6) + (1/6) = 3/6 = 1/2
Then, we calculate the probability of rolling a prime number, that is, 2, 3 or 5.
As we have again 3 numbers, the probability P2 will also be 1/2
Then, the final probability is the product of both P1 and P2:
P = P1 * P2 = (1/2) * (1/2) = 1/4 = 25%
Answer:
28.4 degrees
Step-by-step explanation:
In the diagram attached
Height of the cliff, AB=54 m
Distance of the raft to the base of the cliff, AC=100m
We want to determine the angle of depression from the top of the cliff to the raft. This is angle OBA.
The angle of depression from the top of the cliff to the raft is 28.4 degrees correct to the nearest tenth.
