Y=-3-6+78^34. mmHg gm JHVH
Answer:
23°
Step-by-step explanation:
mABD is just the angle of B
9x-22 = 6x -7
3x -22 = -7
3x = 15
x = 5
9(5) -22
45-22
23
Answer: The weight of X is
of weight of mixture.
Step-by-step explanation:
Since we have given that
Percentage of seed mixture X for ryegrass = 40%
Percentage of seed mixture Y for ryegrass = 25%
If a mixture of X and Y contains 30 percent ryegrass,
Let total seed mixture be 100
So, for seed X = x
For seed Y = 100-x
So, According to question,
![0.4x+0.25(100-x)=30\\\\0.4x+25-0.25x=30\\\\0.15x=30-25\\\\0.15x=5\\\\x=\dfrac{5}{0.15}\\\\x=\dfrac{100}{3}](https://tex.z-dn.net/?f=0.4x%2B0.25%28100-x%29%3D30%5C%5C%5C%5C0.4x%2B25-0.25x%3D30%5C%5C%5C%5C0.15x%3D30-25%5C%5C%5C%5C0.15x%3D5%5C%5C%5C%5Cx%3D%5Cdfrac%7B5%7D%7B0.15%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B100%7D%7B3%7D)
So, weight of mixture X is given by
![\dfrac{\text{Weight of X}}{\text{Weight of mixture}}\times 100\\\\=\dfrac{\dfrac{100}{3}}{100}\times 100\\\\=\dfrac{100}{3}\%\\\\=33\dfrac{1}{3}\%](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BWeight%20of%20X%7D%7D%7B%5Ctext%7BWeight%20of%20mixture%7D%7D%5Ctimes%20100%5C%5C%5C%5C%3D%5Cdfrac%7B%5Cdfrac%7B100%7D%7B3%7D%7D%7B100%7D%5Ctimes%20100%5C%5C%5C%5C%3D%5Cdfrac%7B100%7D%7B3%7D%5C%25%5C%5C%5C%5C%3D33%5Cdfrac%7B1%7D%7B3%7D%5C%25)
Hence, the weight of X is
of weight of mixture.
