$147.68 is the awnser too this one
Answer: B
Step-by-step explanation:
A = 0/360 ×π×r^2
=135/360×π×11×11
=142.55 yd^2
If 19 is half (50%) of something, find that number you would just have to multiply 19 by 2.
This means that 19 is 50% of 38.
Answer:
144 ways
Step-by-step explanation:
Number of paintings = 7
Renaissance = 4
Baroque = 3
We are hanging from left to right and we will first hang Renaissance painting before baroque painting.
For Renaissance we have 4! Ways of doing so. 4 x3x2x1 = 24
For baroque we have 3! Ways of doing so. 3x2x1 = 6
We have 4!ways x 3!ways
= (4x3x2x1) * (3x2x1) ways
= 144 ways
Therefore we have 144 ways to hang the painting.
20,21,22,23,24 add them all and you get 110
