Answer:
A
Step-by-step explanation:
Using the pythagorean theorem, ![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
we plug the numbers in; ![3^{2} + 6^{2} =c^{2}](https://tex.z-dn.net/?f=3%5E%7B2%7D%20%2B%206%5E%7B2%7D%20%3Dc%5E%7B2%7D)
9+36=c^2
45=c^2
sqr root of 45 is ![\sqrt{45}](https://tex.z-dn.net/?f=%5Csqrt%7B45%7D)
next find the positive perfect sqr root of 45 which will be 9.
9 goes into 45 5 times so it will be ![\sqrt{9x5}](https://tex.z-dn.net/?f=%5Csqrt%7B9x5%7D)
Sqr root of 9 is 3 so it will be ![3 \sqrt{5}](https://tex.z-dn.net/?f=3%20%5Csqrt%7B5%7D)
Answer:
60% of 25 = 15 and 2.52
Step-by-step explanation:
8 / 24 = 0.3
1 muffin = 0.3 cups of flour
30 muffins * 0.3 cups of flour= 10 cups of flour.
10 cups of flour are needed to make 30 muffins.
