Answer:
12 of $3.2 grade is needed
Step-by-step explanation:
Answer:
22.2m
Step-by-step explanation:
vol of a sphere = 4/3 x pi x r^3
vol of a hemisphere is 1/2 the vol of a sphere, so vol of a hemisphere= 2/3 x pi x r^3
2/3pi x r^3 = 257
Divide both sides by 2/3pi
r^3 = 122.708
Cube root both sides.
r = 11.077
Diameter is twice the radius, so diameter = 22.154m
To the nearest 10th of a meter this is 22.2m.

To find whether or not the ratios are proportional, simplify. The first ratio is already simplified, so simplify the second one. to do this, find what factors 24 and 35 have in common.
Factors of 24: 1, 2, 3 ,4, 6, 8, 12, 24
Factors of 35: 1, 5, 7, 35
It looks like there are now common factors between 24 and 35. For the ratios to be proportional, they have to have the same value. If 24/35 can't be simplified to 4/7, the factors are not proportional.
So, to answer the question: No, the ratios are NOT proportions. I hope this helps and have a great rest of your day!
