Answer:
(x-4) (x-1)(x+1)
Step-by-step explanation:
denominator 1 x^2 -5x+4
factor
(x-4) (x-1)
denominator 2 x^2 -16
factor
(x-4) (x+4)
to find the LCD you have to find the LCM of the denominator
LCM Multiply each factor the greatest number of times it occurs in any of the numbers.
LCD: (x-4) (x-1)(x+1)
Answer:
615.44 units squared
Step-by-step explanation:
Let the volume and surface area of the sphere be V and S respectively.
![\therefore V = \frac{28}{3} \times S\\\\\therefore \frac{4}{3} \pi {r}^{3} = \frac{28}{3} \pi {r}^{2} \\ \\ \frac{ {r}^{3} }{ {r}^{2} } = \frac{28\pi}{3} \times \frac{3}{4\pi} \\ \\ r = 7 \: units \\ \\ \because S = 4\pi {r}^{2} \\ \\ \therefore \: S = 4 \times 3.14 \times {7}^{2} \\ \\ \therefore \: S = 12.56 \times 49 \\ \\ \therefore \: S =615.44 \: {units}^{2}](https://tex.z-dn.net/?f=%5Ctherefore%20V%20%3D%20%5Cfrac%7B28%7D%7B3%7D%20%5Ctimes%20S%5C%5C%5C%5C%5Ctherefore%20%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B3%7D%20%20%3D%20%20%5Cfrac%7B28%7D%7B3%7D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Cfrac%7B%20%7Br%7D%5E%7B3%7D%20%7D%7B%20%7Br%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%5Cfrac%7B28%5Cpi%7D%7B3%7D%20%20%5Ctimes%20%20%5Cfrac%7B3%7D%7B4%5Cpi%7D%20%20%5C%5C%20%20%5C%5C%20r%20%3D%207%20%5C%3A%20units%20%5C%5C%20%20%5C%5C%20%5Cbecause%20S%20%3D%204%5Cpi%20%7Br%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20S%20%3D%204%20%5Ctimes%203.14%20%5Ctimes%20%20%7B7%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%20S%20%3D%2012.56%20%5Ctimes%2049%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%20S%20%3D615.44%20%5C%3A%20%20%7Bunits%7D%5E%7B2%7D%20)
Percentages are easy to represent as decimals. Just remember this: If the value is under 100%, just place a decimal point in front of the percent value and remove the percentage sign. If it's over 100%, you'd put the decimal after whatever is in the hundreds place. The reason you can do this is because percent represents a value out of one hundred, and decimals do the same representing values as part of one.
So, 39%->.39
Answer:
It would be the square root of 36.
Step-by-step explanation:
The answer is simply all you do is subtract 72 from 97 and you'll have the answer which is 25, so the temperature decreased by 25 degrees
