The answer is B because facts
The ratios of the sides
hypotnuse=2x
x=short leg (oposite 30)
x√3=long leg (oposite 60)
long leg=x√3
to find x, divide by √3
longleg/√3=short leg=x
rationalize denomenator, times √3/√3
(longleg√3)/3=short leg
the legnth of the short leg is
(longleg√3)/3
V= π r^2 h/3
V= π 4^2 9/3
V= π 16 3
V= 150.72
V=151
Explanation
Formula is the first line. R is the radius with us 4 and h is the height which is 9. Substituting these values into the formula will get you pi times 4 squared times 9 divided by 3. When simplified this gets pi times 16 times 3. Using the approximate value of pi which is 3.14, multiple it with 16 and 3 will get you 150.72, round this to 150.8, which rounds to 151.
Hope this helps
to answer on cube root we need to use the prime factorisation.
which means using only prime number and dividing the number by suitable prime number.
after find prime factorisation we know that cube root is 3th power of number.
so if we have same three number we need to take it as one because it is a cube root .
for example![\sqrt[3]{5*5*5} =\sqrt[3]{5^3} =5.](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B5%2A5%2A5%7D%20%3D%5Csqrt%5B3%5D%7B5%5E3%7D%20%3D5.%20)
Answer:
2 equations
28.8/100*75 = $21.6 - 10% 21.6/100*90 = $19.44
Step-by-step explanation:
First one we determine the 25% ans second we deduct 10% from that result.
