What is 3 root of 384?

Mathematics
1 answer:
Brrunno [24]3 years ago
5 0
1. The cube root of 384 can be rewritten as the cube root of (8*48). That can be simplified to 2 cube root of 48. That can be simplified down further to 2 cube root of (6*8), which is 2*2 cube root of 6, or 4 cube root of 6. So, the answer is C.

You do the same thing for each of the problems. If you actually want me to just give you the answers, they are:
1. C
2. D
3. D

Q#1:The volume of a cube is 46656 cubic metres.Find the length of each side?
Lady_Fox [76]

Answer:

Step-by-step explanation:

1) To find the cube root of a number prime factorize

46656 = 2*2*2*2*2*2 * 3 * 3 * 3 * 3 * 3 * 3

\sqrt[3]{46656}=\sqrt[3]{2*2*2*2*2*2*3*3*3*3*3*3}  =2*2*3*3 = 36

Length of each side = 36 m

Q) i) -512 = (-8) * (-8)*(-8)

-512 is a cube number

v) -17576 = (-26) * (-26)*(-26)

        -17576 is cube number

The product of two positive integers plus their sum is 95. The integers are relatively prime, and each is less than 20. What is
creativ13 [48]
Let the fist integer be x, the second is x+20
the product of the numbers is:
x(x+20)
the sum of the numbers is:
x+x+20=2x+20
the sum of the above operations will give us:
2x+20+x^2+20x=95
x^2+22x+20=95
this can be written as quadratic to be:
x^2+22x-75=0
solving the above we get:
x=3 and x=-25
but since the integers should be positive, then x=3
the second number is x+20=3+20=23
hence the numbers are:
3 and 23

The two triangles we can see in the diagram are similar, which means that their measurements are proportional. Line MN on the larger triangle MNP is 71.5ft long, and its corresponding line, MA, on the smaller triangle is 71.5-22= 49.5ft long. This means that the scale factor from the bigger to the smaller triangle is 71.5/49.5=13/9.
If line MP on the bigger rectangle is 97.5ft long, then its corresponding line, MB, must be 97.5÷13/9=67.5 ft long.
Therefore, x=67.5 ft
