The formula of a volume of a rectangular prism a × b × c:
![V=abc](https://tex.z-dn.net/?f=V%3Dabc)
We have two rectangular prisms.
![1:\ 2cm\times2cm\times5cm\\2:\ 2cm\times2cm\times6cm](https://tex.z-dn.net/?f=1%3A%5C%202cm%5Ctimes2cm%5Ctimes5cm%5C%5C2%3A%5C%202cm%5Ctimes2cm%5Ctimes6cm)
Calculate the volume:
![V_1=2\cdot2\cdot5=20(cm^3)\\\\V_2=2\cdot2\cdot6=24(cm^3)](https://tex.z-dn.net/?f=V_1%3D2%5Ccdot2%5Ccdot5%3D20%28cm%5E3%29%5C%5C%5C%5CV_2%3D2%5Ccdot2%5Ccdot6%3D24%28cm%5E3%29)
The volume of the irregular figure:
![V_F=V_1+V_2\\\\V_F=20cm^3+24cm^3=44cm^3](https://tex.z-dn.net/?f=V_F%3DV_1%2BV_2%5C%5C%5C%5CV_F%3D20cm%5E3%2B24cm%5E3%3D44cm%5E3)
Whats the question suposed to say
Hello from MrBillDoesMath!
Answer:
L = 35, W = 25
Discussion:
The attachment shows that
P = 2L + 2W = 120
and
L = 10 + W
2L + 2W = 120 => Substitute the last equation into the first one
2(10 + W) + 2W = 120 =>
20 + 2W + 2W = 120 => combine like terms
20 + 4W = 120 => subtract 20 from both sides
4W = 120 -20 = 100 => divide both sides by 4
W = 100/4 = 25
Hence, L = 10 + W = 10 + 25 = 35
Thank you,

Subtracting ‘blank’ space from a larger figure:
(5*12) - (6*3) = 42
60 - 18 = 42
5*12 = 60
6*3 = 18
Breaking down the figure into smaller figures:
(12*2) + (3*3) + (3*3) = 42
12*2 = 24
3*3 = 9
3*3 = 9
Answer:
P(5R) = 0.60^5
P(5R) = 0.07776 = 0.078
Therefore the probability that it will be effective in each of five (5 out of 5) separate trials is 0.078
Step-by-step explanation:
Given;
The probability that the rhythm method of contraception is effective once is P(R) = 0.60
The probability that it will be effective n times is;
P(nR) = 0.60^n
For this case n= 5
P(5R) = 0.60^5
P(5R) = 0.07776
P(5R) = 0.078
