<span>DH = x + 2, HF = 2y, GH = 3x – 3, and HE = 5y + 1
DH = HF
</span>x + 2 = 2y
and
GH = HE
3x – 3 = 5y + 1
so now you have
x + 2 = 2y
3x – 3 = 5y + 1
re-write and simply
x = 2y - 2
3x = 5y + 4
substitute x = 2y - 2 into 3x = 5y + 4
3x = 5y + 4
3(2y - 2) = 5y + 4
6y - 6 = 5y + 4
y = 10
x = 2y - 2
x = 2(10) - 2
x = 20 - 2
x = 18
answer
x = 18 and y = 10
I think since the boy runs 9/10 in 5 minutes you are supposed to times that by 12 because if you count by fives the number 60 stops at 12 so times that then you will get 108/10 then simplify it then it will be 10 8/10
Answer: ![h=8.33\ cm](https://tex.z-dn.net/?f=h%3D8.33%5C%20cm)
Step-by-step explanation:
Given
The length of a cuboid is ![l=15\ cm](https://tex.z-dn.net/?f=l%3D15%5C%20cm)
breadth is ![b=12\ cm](https://tex.z-dn.net/?f=b%3D12%5C%20cm)
Total surface area is ![S.A.=900\ cm^2](https://tex.z-dn.net/?f=S.A.%3D900%5C%20cm%5E2)
Surface area is given by ![2(lb+hl+bh)](https://tex.z-dn.net/?f=2%28lb%2Bhl%2Bbh%29)
Insert the values
![\Rightarrow 900=2(15\times 12+15h+12h)\\\Rightarrow 450=225+27h\\\Rightarrow 225=27h\\\Rightarrow h=8.33\ cm](https://tex.z-dn.net/?f=%5CRightarrow%20900%3D2%2815%5Ctimes%2012%2B15h%2B12h%29%5C%5C%5CRightarrow%20450%3D225%2B27h%5C%5C%5CRightarrow%20225%3D27h%5C%5C%5CRightarrow%20h%3D8.33%5C%20cm)
The probability of rolling a die is 0.25.
What is probability?
- Probability is a number that indicates the likelihood of an event occurring.
- Probability is characterized by the ratio of favourable outcomes to all outcomes.
- Probability is calculated as follows: N = N samples / N favourable outcomes.
A fair dice is thrown twice as a matter of course. The following formula will be used to determine the Probability of at least one even number:
Number of successful outcomes = 2, 4, and 6 = 3
Total favourable outcomes after two rolls are 3 x 3 or 9.
6 times 6 samples equals 36 samples.
The likelihood will be computed as follows:
Probability is calculated as follows: N = N samples / N favourable outcomes
9/36 is the probability.
Probability is equal to 0.25.
Consequently, the Probability of at least once receiving an even number is 0.25.
