Answer:
Step-by-step explanation:
a) Percentage of potato filling = 100 - (30 + 25) = 100 - 55 = 45 %
b) Let the number of pies sold = x
45% of x = 90
![\dfrac{45}{100}*x=90\\\\\\x=90*\dfrac{100}{45}\\\\\\x=2*100\\](https://tex.z-dn.net/?f=%5Cdfrac%7B45%7D%7B100%7D%2Ax%3D90%5C%5C%5C%5C%5C%5Cx%3D90%2A%5Cdfrac%7B100%7D%7B45%7D%5C%5C%5C%5C%5C%5Cx%3D2%2A100%5C%5C)
Number of pies = 200
c) Number of cheese filling = 30% of 200
![=\dfrac{30}{100}*200\\\\= 30*2\\\\\\= 60](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B30%7D%7B100%7D%2A200%5C%5C%5C%5C%3D%2030%2A2%5C%5C%5C%5C%5C%5C%3D%2060)
Number of beef pies = 25% of 200
![=\dfrac{25}{100}*200\\\\\\=25*2\\\\= 50](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B25%7D%7B100%7D%2A200%5C%5C%5C%5C%5C%5C%3D25%2A2%5C%5C%5C%5C%3D%2050)
Difference = 60 - 50 = 10
There are 10 more cheese pies than beef pies.
Answer:
512 is a perfect cube because 512 = 8 times 8 times 8
Step-by-step explanation:
A perfect cube is a number that can be rewritten as a product of three identical numbers.
For example: 8 is perfect cube as 8 can be rewritten as:
8 = 2 × 2 × 2
So, from the definition of the perfect cubes, the option that matches it is third option.
512 is a perfect cube as it can be expressed as the product of 8 three times.
512 = 8 × 8 × 8
Therefore, third option is correct.
All the remaining options doesn't fulfill the definition of perfect cubes.
Depends how you were taught to solve it but if it were me I’d choose B) minimum value at -6
Answer:
cylinder radius and height
cone radius height
sphere raduis
Let the angles be 3x,3x and 4x
so 3x+3x+4x = 180
therefore x= 18
so, angles are 54,54,72 °
so it's B !!
