Answer:
4 : 7
Step-by-step explanation:
No. of families = 2400
No. of cars = 4200
Family : Cars
= 2400 : 4200
= 24 : 42
= 6 x 4 : 6 x 7
= 4 : 7

As 64 is a perfect cube, the coefficient part does not present any problems. However, for the variable with an exponent, it is easier to obtain the cube root by multiplying the exponent by (1/3), since the cube root operator is equivalent to raising a number to the power of (1/3). This is shown below:
cube root (64x^12) = 4 * x^(12)(1/3) = 4 *x^4
Therefore, the answer is 4x^4.
(-3 - 2i) x (-4+ 2i) if you simplify using FOIL you will get 16+2i
Answer:
D 381.7 in^3
Step-by-step explanation:
V=4/3pi r^3
V=4/3pi 4.5^3
4/3x3.14x4.5x4.5x4.5
It is approximately 381.51 when you use 3.14 as pi. This is closest to answer D, so I would assume it is that.
Sorry, I thought it said circle at first.
